Zhongxin Jingwei Client September 16 (Feng Fang) Recently, many places have successively issued new provident fund policies, stipulating that real estate development enterprises shall not restrict, obstruct or refuse buyers to use housing provident fund loans by raising housing sales prices and reducing price discounts. This is one of the illegal acts of real estate development enterprises that are mainly rectified by the Ministry of Housing and Urban-Rural Development and other seven departments.

　　On June 28th, seven departments, including the Ministry of Housing and Urban-Rural Development, jointly issued the "Notice on Launching Special Actions in Some Cities to Combat Illegal Acts against the Interests of the Masses and Control the Chaos in the Real Estate Market", which focused on six kinds of illegal acts of real estate development enterprises, including restricting, obstructing and refusing buyers to use housing provident fund loans or mortgage loans.

　　1 province and 9 cities responded within 80 days.

　　According to the incomplete statistics of the Sino-Singapore Jingwei client (WeChat WeChat official account: jwview), since the announcement of the notice on June 28th, nine cities including Xinxiang, Foshan, Chengdu, Urumqi, Yichang, Beijing, Zhengzhou, Luoyang and Nanjing, as well as Hunan Province, have successively issued new provident fund policies, specifically to rectify the illegal behaviors of housing enterprises refusing to purchase houses with provident fund loans in disguise.

　　Hunan, Nanjing, Foshan and other places have issued corresponding plans or measures to crack down on the illegal acts of the above-mentioned housing enterprises. On September 12, the Interim Measures for the Administration of Serious Dishonest List of Real Estate Market Operators in Hunan Province was promulgated, which stipulated that if real estate enterprises restrict, obstruct or refuse to use housing provident fund loans or mortgage loans, they will be blacklisted by real estate authorities at or above the county level.

　　On August 15th, Yichang Housing Provident Fund Management Center held a special office meeting to arrange the deployment center to carry out the special rectification action of "restricting, refusing and obstructing the use of provident fund loans by buyers".

　　In addition, Beijing, Chengdu, Zhengzhou, Luoyang, Xinxiang, Urumqi and other cities have issued notices or announcements respectively, stipulating that housing companies and intermediaries shall not restrict, obstruct or refuse buyers to use housing provident fund loans by raising housing sales prices and reducing price discounts. Chengdu Housing Provident Fund Management Center said on August 13th that it will focus on rectifying the illegal behaviors of development enterprises that restrict, obstruct and refuse the use of provident fund loans by employees who purchase houses through on-site inspections, unannounced visits and key spot checks.

　　However, this is not the first time that the Ministry of Housing and Urban-Rural Development and other relevant departments have mentioned safeguarding the rights and interests of provident fund housing loans.

　　On December 26th, 2017, the Ministry of Housing and Urban-Rural Development, the Ministry of Finance, the Bank of China, and the Ministry of Land and Resources jointly issued the Notice on Safeguarding the Rights and Interests of Housing Provident Fund Deposited in Employees’ Housing Loans, demanding that real estate development enterprises and sales intermediaries that restrict, obstruct or refuse employees to use housing provident fund loans to purchase houses be ordered to rectify. If the violation is serious and refuses to be rectified, it should be publicly exposed and incorporated into the enterprise credit information system, and it should be dealt with seriously according to law.

　　Since then, various localities have issued documents to regulate the use of housing provident fund loans to purchase houses in commercial housing sales and safeguard the rights and interests of employees who have paid provident fund. According to the preliminary statistics of the Sino-Singapore Jingwei client (WeChat WeChat official account: jwview), Hainan, Guangzhou, Shenzhen, Wuhan, Hangzhou, Xi ‘an, Taiyuan, Lanzhou, Suzhou, Foshan and other 20 leeways have publicly stated that they have ordered the housing enterprises and intermediary agencies that restrict, obstruct or refuse employees to use housing provident fund loans to purchase houses to rectify.

　　"Blackout", fine! Multi-measures to contain violations of housing enterprises

　　According to Xinhua News Agency on April 2, after the notice was issued in December last year, some developers in Shanghai, Guangdong, Fujian and other places still refused provident fund loans in disguise by setting the proportion of subscription funds, the payment period and refusing portfolio loans, which harmed the rights and interests of buyers.

　　Zhang Bo, chief analyst of Anjuke Real Estate Research Institute, said that the slow payment rate is the main reason why developers exclude buyers from using provident fund loans. The complicated process of provident fund loans and the long loan period lead to the decline of enterprise capital turnover rate, and the pursuit of high turnover housing enterprises will have resistance to provident fund loans.

　　Zhang Bo also said that it is often necessary to cooperate with banks in the development of housing enterprises. One of the conditions for many banks to agree to lend is to obtain a large number of high-quality mortgage customers, which is also a reason why developers refuse provident fund loans.

　　Yan Yuejin, director of the think tank research center of Shanghai Yiju Research Institute, believes that due to the tightening of commercial loans, the support for the withdrawal of provident fund can effectively protect renters, the reasonable need to buy a house and the improved demand, and the follow-up should also work hard to implement the policy link.

　　On August 17th, Beijing Housing Provident Fund Management Center stated in the Notice on Further Safeguarding the Rights and Interests of Housing Provident Fund Deposited into Employees’ Housing Loans that the refusal or disguised refusal of housing provident fund loans should be ordered to rectify; Those who refuse to rectify should be publicly exposed. All departments should share the exposure when they break their promises to illegal enterprises or individuals, so that one place is broken and illegal, and it is blocked everywhere.

　　On August 21st, Zhengzhou Municipal People’s Government issued the Notice on Investigating and Punishing Illegal Pre-sale of Commercial Houses according to Law, requiring real estate enterprises to post a written commitment not to refuse buyers to use housing provident fund loans in a prominent position in the sales department after obtaining the Pre-sale Permit of Commercial Houses. Illegal enterprises shall be publicly exposed by the municipal housing provident fund management center, investigated and dealt with by relevant departments according to law, and recorded in enterprise credit files.

　　Nanjing Housing Provident Fund Management Center issued the Measures for the Administration of Housing Provident Fund Mortgage Agreement in Nanjing on September 11th, requiring developers to sign the Nanjing Housing Provident Fund Loan Mortgage Agreement with Nanjing Housing Provident Fund Management Center. Those who refuse or obstruct the purchase of houses with provident fund loans shall be ordered to make rectification; If no rectification is made within the time limit, a fine of not less than 3,000 yuan but not more than 30,000 yuan may be imposed on the unit, and a fine of not less than 200 yuan but not more than 2,000 yuan may be imposed on the person in charge who is directly responsible.

　　Urumqi Housing Provident Fund Management Center published an article entitled "Urumqi Housing Provident Fund Management Center and other five departments jointly act to resolutely safeguard the rights and interests of paid employees’ housing loans" on August 15. According to the article, if there are any violations such as asking buyers to give up their housing provident fund loan rights or adding other restrictions and additional conditions, Or the housing enterprises that have not signed the housing provident fund mortgage loan agreement with Urumqi Housing Provident Fund Management Center within the specified time, and refuse to rectify, will be publicly exposed and taken disciplinary measures such as suspending online signing, suspending the pre-sale fund supervision account fund allocation, and incorporating it into the enterprise credit information system.

　　Zhang Bo believes that to solve the problem of housing enterprises refusing provident fund loans, it is necessary to "block" and "sparse". On the one hand, it is necessary to increase the penalties for developers to refuse provident fund loans, on the other hand, it is necessary to further lower the operating threshold of provident fund loans themselves, simplify the process of provident fund loans, and shorten the time for provident fund loans.

　　The notice issued in December last year pointed out that the housing provident fund management center and the entrusted banks should standardize the loan business process, reduce the examination and approval links and shorten the examination and approval time limit. Complete the examination and approval within 10 working days from the date of accepting the loan application. If the loan is granted, notify the entrusted bank to handle the loan procedures; If the loan is not granted, the reasons shall be explained. (Zhongxin Jingwei APP)

Dear members:

Hello! First of all, thank you for your attention to china network television.

In order to understand users’ evaluation and experience of china network television’s content, china network television is now launching the "Evaluation of User Satisfaction in the Third Quarter of 2010" to improve the content quality of the website and improve the user experience. The deadline for this evaluation is October 10th.

A phone call from Trump to Guo Taiming successfully reversed the collapse crisis of Foxconn’s American factory, which he called "the eighth wonder of the world".

On January 30th, Hu Guohui, the special assistant of Foxconn Chairman Guo Taiming, said in an interview with Reuters that Foxconn was rethinking its plan to invest 10 billion dollars to build an LCD panel factory in Wisconsin, USA, and would shift its recruitment Louis Woo engineers and researchers, rather than the manufacturing workers originally promised in this project. The panel factory plan may be reduced or even shelved.

As soon as the relevant report was published, it caused an uproar in the United States. After all, this largest foreign investment project in the history of the United States not only claims to provide 13,000 blue-collar jobs for Weizhou in the future, but also has always been regarded by Trump as his landmark victory in revitalizing American manufacturing.

On February 1st, Guo Taiming personally released a "real hammer" at Foxconn’s annual conference in Taipei, saying that Weizhou Investment "is making some changes, avoiding mass-produced projects and adjusting to the field of research and development". However, on the evening of Beijing time, an overseas phone call from Trump personally made Guo Taiming change his attitude again.

Foxconn issued a statement later that day, saying, "The Group will build a sixth-generation panel factory in Wisconsin Valley Science and Technology Park as planned. The whole park will serve as a local high-tech advanced manufacturing center and a hub for regional innovation and technology in the future. Shortly afterwards, Trump also announced this "great news" on Twitter.

In just two days, a storm suddenly happened and unexpectedly subsided. However, the "black history" of Foxconn’s repeated changes in Weizhou and other investment projects still makes the "10 billion dollar factory" under construction look distant.

On July 26, 2017, Foxconn officially announced the plan to set up a factory in Weizhou. At the White House press conference, Trump appeared and said: "If I am not elected, he (Guo Taiming) will definitely not invest this $10 billion. This is a great day for American workers and American manufacturing. Scott Walker, then governor of Weizhou, said: "This is a once-in-a-century opportunity for our state and even the whole United States, and Wisconsin is ready. 」

In order to attract Foxconn to Weizhou, the Weizhou government offered a total of $4 billion in tax relief and a series of incentive policies. However, according to the agreement signed by the two parties, Foxconn must achieve certain goals in capital investment and job creation every year in order to obtain the policy "red envelope" of that year. In 2018, Foxconn only created 178 jobs in Weizhou, which failed to meet the requirements of 260 jobs, thus missing the tax incentives of up to 9.5 million US dollars in that year.

Initially, Foxconn planned to produce large-screen panels suitable for TV and other consumer products in Weizhou factory. However, Hu Guohui said in an interview on January 30 that the cost of manufacturing TV display screens in the United States will increase due to the relatively high labor cost in the United States, so Foxconn’s investment direction in Weizhou will change: "As far as TV is concerned, we have no foothold in the United States and we are not competitive. 」

Hu Guohui said that instead of producing LCD panels in the United States, it would be more profitable to produce them in Greater China and Japan, then ship them to Mexico for final assembly, and then import the finished products into the United States. He said that this is a supply chain that conforms to Foxconn’s current "mobile and good business model."

Hu Guohui said that Foxconn would rather set up a "technology center" in Weizhou than a manufacturing plant. He revealed that this "technology center" will mainly include research departments and packaging and assembly businesses to produce technical products used in industry, health care and other professional fields.

The focus of Foxconn’s talent recruitment in Weizhou has also shifted. Hu Guohui said that in the future, about three-quarters of Foxconn’s recruitment in Weizhou will focus on R&D and design, rather than the blue-collar manufacturing workers promised before. "In Wisconsin, we are not building a factory. You can’t look at our investment in Weizhou from the perspective of a factory. 」

On February 1st, when Guo Taiming attended Foxconn’s annual conference in Taiwan Province, he also took the initiative to mention the change of Weizhou project. Guo Taiming said that the original plan was to do mass production, but in the United States, scientific and technological innovation has a good environment, talents and educational institutions, so the plan was adjusted to the direction of technology research and development.

Guo Taiming believes that investment projects and technologies in Weizhou should be "re-examined" to meet the current global market environment and meet the needs of local and customers, but he also said that the commitment to create 13,000 jobs has not changed. However, according to some sources, Foxconn has slowed down the pace of recruitment in Weizhou. It was originally expected to employ 5,200 people locally by 2020, but this number has been greatly reduced to 1,000. As for when Foxconn can complete the goal of 13,000 jobs, it is still unknown.

On the other side of the Pacific Ocean in the United States, Hu Guohui’s remarks were published by Reuters, which caused a sensation in Weizhou and caught officials off guard.

Tony Evers, the current governor of Weizhou, said that he was "surprised" by Foxconn’s latest plan. In last year’s election campaign against former Republican Governor Scott Walker, Democrat Tony Evers has always been a critic of Foxconn’s project. He said that Foxconn’s ever-changing plans have caused him a lot of troubles, and that the state’s $4 billion incentive for Foxconn is too high.

Gordon Hintz, the minority leader of the Victorian Parliament, said that Hu Guohui’s statement was completely contrary to Foxconn’s commitment made 18 months ago to revitalize the manufacturing industry in the southeastern part of the state. "Foxconn’s every step is exaggerated and it can’t achieve its goal. For taxpayers in Weizhou, this is simply disastrous news. 」

Nate Jensen, who studies incentive policies at the University of Texas at Austin, said that in view of the fact that Victoria’s drastic policies for Foxconn are extremely expensive and Foxconn’s investment changes are reducing the selling point of middle-income jobs, Victorian government officials should consider whether to renegotiate the incentive policies with Foxconn. Gordon Hintz also pointed out that "this is not the agreement promised to Wisconsin before". He said that local and state governments have invested millions of dollars in road improvement and other infrastructure, hoping to hold public hearings on Foxconn’s agreement and any renegotiation of the state contract.

On the occasion of discussions from all walks of life, Trump came out.

On the evening of February 1st, Foxconn issued a statement confirming that Guo Taiming and Trump had just spoken by phone in person, and "after the fruitful communication between the company team and the White House officials in the past year", Foxconn will continue to promote the planned Weizhou factory. Foxconn will build a "sixth generation" factory to produce small and medium-sized LCD panels as originally planned, including TV assembly and artificial intelligence R&D center, and will further expand its investment fields. Trump then wrote on Twitter: "After I talked to Guo Taiming, Foxconn in Wisconsin had good news. 」

The next day, February 2, at Foxconn’s annual meeting, Guo Taiming revealed the specific contents of his conversation with Trump: "Yesterday, I was fortunate to receive a phone call from Mr. Trump, the president of the United States, and he called me. In fact, I also went to the White House in December last year and had a detailed talk with him about the future economy and Sino-US trade, as well as investment in the United States. President Trump not only wants me to continue to invest in the research and development and manufacturing of LCD in Wisconsin, but also for self-driving and future aerospace technology. Then he also hopes that young talents can return to the midwest from (the United States) and invest in research and development, which gives us high expectations. 」

The Taiwanese businessman also turned Foxconn’s troubles in Weizhou into a compliment to Trump: "Mr. President, the unemployment rate in Wisconsin has dropped from 5-6% to 2.9% since you took office. That is to say, I can’t find any workers at all. Trump responded that he would try his best to help.

Guo Taiming believes that the United States is the largest market in the world, with the most talents, the highest technology and the best business environment: "Investing in the United States is a completely correct decision and in line with future economic trends. 」

A phone call has solved the recent worries of Weizhou, but it is difficult to worry about it.

The Wall Street Journal said that before the Weizhou project, Foxconn had many statements about expanding manufacturing in the United States, but they were not put into practice. In 2013, Foxconn said that it might invest $40 million in Pennsylvania for manufacturing and research. In 2014, Guo Taiming said that he was studying the feasibility of establishing an advanced display manufacturing factory in the United States. So far, neither of these two ideas has made any progress.

After Trump and Guo Taiming talked, CNN still reported that some experts who have been tracking the progress of Foxconn’s Weizhou project still doubt whether Foxconn can fully fulfill everything it promised to Weizhou. Steven Deller, a professor of economics at the University of Wisconsin, laughed after learning Foxconn’s latest statement: "I think Foxconn is playing tricks. They have done the same thing to India, Brazil and Pennsylvania. They have a black history of making promises but not fulfilling them. 」

Tim Culpan, a Bloomberg columnist who has long observed Foxconn’s dynamics, believes that Foxconn’s plan to invest in panels in the United States is completely unreasonable. He believes that it is not in Victoria’s interest to be too closely related to the panel industry, because it is a highly circular and cost-sensitive industry, and even if it recruits manpower on a large scale, it may lay off a large number of employees soon. He also said that recruiting more R&D jobs in the United States is only Foxconn’s "wishful thinking" because "there are not so many talents in the United States who can set foot in these fields. 」

On January 31st, Global Times, the official media in China, published an editorial article entitled "The Foxconn Project Changed from a Big Apple to a Small Begonia, Lessons". The article wrote in a sarcastic tone that Foxconn’s investment in Weizhou "is a strange investment that is economically unprofitable only by snapping fingers without using calculators". The article sarcastically said that Foxconn can’t really put it above "love for profit" if it wants to show "love for America". "If the Victorian government refuses to pay a huge sum of real money for all this, Foxconn will really go there to open an LCD factory with the level of" the eighth wonder of the world ",just to send it a certificate from the United States, which is really a ghost. 」

From the perspective of a multinational company, Guo Taiming has his own thoughts. He said at Foxconn’s annual meeting this year: "No matter what the outcome of the future world trade war is, on the one hand, the market will be in the west, the North American Free Trade Area headed by the United States, and on the other hand, the economic zone with a population of 1.4 billion will be headed by Chinese mainland. We have made great progress and investment on both sides, and both have trained many talents. 」

The practice of "seeing ghosts" in others’ eyes may be Foxconn’s "survival rule" under the new situation, and it also once again confirms Guo Taiming’s straightforward declaration that "businessmen have no motherland, and the market is my motherland."

First, the third generation synchrotron radiation light source with the highest energy in the world

SPring-8, a large-scale synchrotron radiation facility in Japan, is located in Harima Science Garden City, Hyogo) in Hyogo Prefecture, the center of the Japanese archipelago. It is the third generation synchrotron radiation source with the highest energy in the world. Its English name is Spring-8, which means "8GeV Super Photon Ring", that is, the output power is 8 GeV.

In 1991, under the leadership of MEXT (Ministry of Education, Culture, Sports, Science and Technology), Jaeri (Japan Atomic Energy Research Institute) and Riken (the Institute of Physical and Chemical Research) of Japan began to jointly build SPring-8. The construction cost of the first phase is about 110 billion yen, and the land is donated by Hyogo Prefecture for free. With the joint support of the county government, the county university, various research institutes and commercial enterprises, the project was completed in 1997, and the facilities were opened, which were managed by JASRI (Japan Synchrotron Radiation Research Institute), including the operation, maintenance, transformation, user service and scientific research and development of light sources. JASRI is the only statutory management organization of SPring-8, which is private and non-profit, and employs more than 1,000 employees, 80% of whom are researchers and technicians. From October 1997 to 2010, SPring-8 has built 55 beam line stations.It has served more than 100,000 people in science, industry and business circles in Japan and the world.

Spring-8 in Japan, advanced photon source APS (Argone) in Argonne National Laboratory of the United States and European synchrotron radiation facility ESRF (Grenoble) in Grenoble, France are the three largest high-energy synchrotron radiation facilities in the world.

Third, structural exploration

The accelerator of SPring-8 mainly consists of four parts:　

* injector, Linac, 1GeV；;　

* Booster, 8 GeV;

* large Storage Ring, storage ring, 8GeV, used for high brightness X-ray;　

* Small storage ring, NewSUBARU, 1.5GeV, used for medium short pulse soft X-ray.

　　1. Injector (Linac)　

The linear accelerator section is equipped with 26 3-meter-long accelerating units to accelerate the electron beam energy to 1GeV. The red part in the picture below is a quadrupole magnet used to focus the electron beam.　　

Linear accelerator unit 1　

The electron beam is generated by a thermionic gun impregnated with barium and tungsten. The ion gun is located on the high-voltage board with a voltage of about 180KV. The pulse duration is 1ns or 40ns. The selected beam is focused on a buncher and accelerated to 1GeV energy with 25 accelerating cavities. Electron beam energy dispersion is reduced by energy compressor system (ECS). Then, the linear accelerator as the injector transports the electron beam to the intensifier or the NewSUBARU small storage ring.　

Some parameters of linear accelerator:

2. Booster Synchrotron

Annular, with a circumference of 396 meters. The 1GeV electron beam output from the linear accelerator will be accelerated to 8GeV in the intensifier. The blue image below shows the deflection magnet, which is used to generate synchronous radiation light; The yellow part is a six-stage magnet for stabilizing the electron beam.

Intensifier tunnel intensifier branch point (left) electron beam transport line SSBT (right)　

In FODO, the magnetic focusing structure of the intensifier, bending magnets and quadrupole magnets are alternately arranged, and the repetition frequency of injection, acceleration and output is set to 1Hz, and the harmonic number is 672. If a single beam is injected into the storage ring, an RF elimination system is installed to eliminate other electron beams adjacent to the main beam. The special timing system injects different beams according to the types of light required by each outlet station of the storage ring.　

Some parameters of the enhancer:

3. The large Storage Ring (storage ring)

The electron beam is injected into the storage ring from the transport line SSBT (left).

Huge ring with a circumference of 1436 meters. Its conventional unit consists of 2 deflection magnets, 10 four-stage magnets and 7 six-stage magnets, and its length is about 30 meters. The linear joints are located between conventional units, and are used to install plug-ins, RF accelerating cavities, beam injection systems, beam diagnosis systems, etc., with a total of 44 linear joints.　

Some parameters of large storage ring:

The large storage ring can store 8GeV electron beams for a long time, more than 100 hours. The energy consumed by synchrotron radiation is replenished by accelerating equipment installed in four radio stations around the storage ring. The constant current (top-up) injection mode effectively ensures the constant beam current intensity in the storage ring.　

Link: The 86th academic seminar of the Oriental Science and Technology Forum was held on December 7-8, 2006, with the topic of "beam orbit stability of the third generation synchrotron radiation light source".　

Dr Kouichi Soutome from Japan synchrotron radiation research institute (JASRI) gave a special report on "constant current injection and beam orbit stability of SPring-8". He first emphasized the necessity of providing users with a stable X-ray beam for precision experiments. In order to stabilize the beam position, it is necessary to restrain the beam trajectory change. He pointed out that the top-up injection mode with constant beam intensity in the storage ring can effectively ensure the stability of the synchrotron radiation light intensity. For this reason, SPring-8 has made great efforts to study the sources of various factors that cause orbit change, such as the change of magnet power supply and the vibration of vacuum chamber caused by cooling water.

SPring-8 also improves the beam trajectory correction system and the corresponding measurement system. For top-up implantation, SPing-8 adopts many measures, such as reducing the vibration of stored electron beam caused by implantation, reducing the loss of implanted electron beam, and maintaining long-term high-purity single beam implantation. Finally, he reported the stability of SPring-8 in beam orbit and the performance of top-up injection operation mode. The total current stability in SPring-8 storage ring is controlled within 0.1%, and the current intensity inconsistency of each beam is also controlled within 10%.　

4. NewSUBARU

　　NewSUBARU storage ring　

NewSUBARU, a small storage ring with 1.5GeV, is mainly used to study the application of soft X-ray in industrial field. Built in 1998, Lasti (Laboratory of Advanced Science and Technology for Industry) of Hyogo University is responsible for its operation.　

The circumference of the small storage ring is about 119 meters, and it consists of two 14-meter and four 2.6-meter straight-line sections. In the long straight section, an 11-meter-long undulator and an optical klystron free electron laser device are installed. The electron beam of 1GeV in the linear accelerator can be directly injected into the storage ring.

　　11-meter-long undulator

Some parameters of small storage ring:

Four, beam line and experimental station

SPring-8 has 22 beam lines led by deflection magnets, and up to 24 can be built. There are 26 beam lines led out by the insert, up to 34 can be built, and the length of the straight line section is 4.5 meters; There is one beam line led by the long insert, and at most four beams can be built, and the length of the long straight line section is 25m. These beam lines are generally designed within 80 meters, but 9 can extend to 300 meters and 3 can extend to 1 kilometer.　

1. Layout and classification　

The front-end assembly of the beam line is designed to withstand radiation power, reduce the thermal load of the first optical element in contact, and protect the vacuum of the storage ring in case of beam line failure.

　　Beam line front end

　　Beam line

* common beam line

* Japan Atomic Energy Development and Research Institute (JAEA) beam line

* RIKEN beam line

* Other unit beam lines

* accelerator beam diagnosis

* Taiwan Province’s exclusive beam line

Taiwan Province National Synchrotron Radiation Research Center has built two hard X-ray beams dedicated to Taiwan Province on SPring-8: for the study of biological structures and materials and inelastic X-ray scattering. Taiwan Province has 75% to 80% of the usage time.

chronicle of events

December 18th, 1998: Signed the cooperation memorandum and contract of SPring-8 Taiwan Province exclusive beam line.　

October, 2000: Research on Biological Structure and Materials: The beam line came out and started trial operation. Derived from the deflection magnet of the storage ring, it can be used for researchers to engage in experiments such as X-ray absorption spectrum, high-resolution X-ray scattering, protein crystallography and micro-area diffraction, conduct forward-looking scientific experiments in life science, physics and chemistry, and open up new research fields of various cutting-edge materials.　

December 15th, 2000: Opening ceremony of beam line was held.

2. Introduction of some experimental stations

* BL02B2 (powder diffraction)

A large Debye-Scherrer camera with a radius of 286.5mm was installed in the shed. Its imaging plate is the detector, which is used to collect all powder patterns synchronously. The camera can be used in a wide temperature range (15 k—1000 k), and it can realize the rapid collection of high calculation statistics and high angular resolution powder diffraction data.

* BL04B1 (high pressure and high temperature)

SPEED-Mk. II, a high-pressure equipment, is a double-layer 1500-ton tamping multi-anvil press. It uses 14*14*14mm sintered diamond anvil to produce high pressure and high temperature conditions, reaching 50 GPa and 2000oC. It can complete the experiments of energy dispersive X-ray diffraction and high-speed CCD imaging.

* BL08W (high energy inelastic scattering)

Compton scattering magnetic spectrometer is mainly composed of 3 T superconducting magnet and 10 germanium solid state detectors (SSDs). Superconducting magnet can switch the magnetic field from -3 T to 3 T within 5 seconds. Germanium SSDs are symmetrically arranged around the grazing X-ray beam, achieving a scattering angle of nearly 180 degrees. The sample temperature is controlled by a cryocooler, which is between 10 K and room temperature.

V. Major scientific research achievements

1. Uncover the secret of the mysterious structure and movement mode of water molecules.

Water is a familiar substance, and the structure of water molecule H2O is well known. But perhaps people haven’t thought deeply: where does ice store huge cooling energy? Why is the density of water the highest at 4oC? But above or below 4oC, the water density decreases? Why is the density of solid ice less than liquid water?

Japanese scientists analyzed the structure of water and ice in SPring-8, and some new discoveries solved the long-debated problem about the nature of water. They successfully conducted Compton scattering experiment by using high-energy inelastic scattering beam line BL08W, directly observed the structure and function of ice at high resolution, and verified the accuracy of molecular dynamics simulation. This basic research result can help to develop thermal storage materials and analyze the thermal storage of new materials in the future. The paper was published in the top American science journals.

In fact, as early as 2008, scientists from RIKEN Institute of Physics and Chemistry in Japan proposed two water states with different hydrogen bonding modes by using BL17SU beam line and soft X-ray spectrum of SPring-8, as well as small angle scattering and Raman scattering.

2. Develop general-purpose plastic materials as strong as iron.

Plastic products such as plastic bags and plastic buckets have become widely used and indispensable items in our daily life because they are light, waterproof and cheap. But at the same time, it also has some disadvantages: low tensile strength, easy deformation and not high temperature resistance. They are synthesized from polymers such as polyethylene and polypropylene, and their structures at the molecular level are composed of long chains of carbon atoms. This "string" structure of polymer makes plastic products as soft as biomaterials. However, scientists have found that the tensile strength of materials will increase with the increase of polymer chain length; When carbon chains have tensile strength similar to covalent bonds of carbon atoms in diamonds, general plastics will harden, but they will not have diamond-like strength.

Distinguished professor Hikosaka of The Graduate School of Integrated Arts and Sciences (Hiroshima University) focuses on the study of polymer long chains and their structural and characteristic changes. He examined the blending phase structure of polyethylene long chain and its influence on properties by X-ray diffraction and other methods. The growth mechanism, sliding and diffusion effect mechanism of ideal polymer crystals are formulated. In 1987, the "sliding diffusion theory of polymer crystallization" was put forward.

The research team led by Professor Iwasaka and his doctoral student Kiyoka Okada, who used BL40B2 beam line in 2003-2007, observed the process of nuclear nucleation. ) From 2007 to 2010, using the X-ray scattering device of SPring-8, a new polypropylene-based plastic with strong tensile force and super heat resistance was successfully developed for the first time: NOCs(nano-oriented crystals).

The reason why ordinary plastics have poor tensile strength is because of low crystallinity. High-quality plastics are those with crystallinity of about 50%. In other words, the higher the crystallinity, the stronger the intermolecular interaction, and the stronger the tensile strength and heat resistance. When polymer molecules are regularly arranged, crystals form. Therefore, in order to improve the crystallinity, it is necessary to arrange the polymer molecules regularly as much as possible.

Professor Masamichi Hikosaka, Dr. Kiyoka Okada, holds a new type of polypropylene.

The research team led by Professor Iwasaka found a method to make polymers regularly arranged when plastics are in molten state, and proved that the crystallinity of the method is 92%. Because the structure of NOCsS looks like a real armor, it is composed of small pieces of iron plates, so the model is called "real armor" model. The tensile strength of the new polypropylene is about seven times higher than that of the ordinary plastic material, the heat-resistant temperature reaches 170°C or higher than 176°C, the light transmittance is 99%, and it is recyclable and cheap, because only one process is needed in the traditional polypropylene production process.

This wonderful new plastic material is most likely to be used in the transformation of steel body in traditional automobile industry. Although the thickness of the body will be doubled, its weight is only a quarter of that of steel.

3. Analyze the change of dynamic structure of calcium pump.

A variety of ions participate in the biological activity of organisms. Calcium 2+ ion promotes muscle movement and is one of the most important ions in organisms. It is stored in the endoplasmic reticulum of myofibrils. When calcium ions are released into muscle cells, muscles contract. At the same time, calcium ions need to return to the endoplasmic reticulum to relax the muscles. A membrane protein called calcium pump is responsible for pumping back calcium 2+ ions.

Pumping back calcium ions involves two processes: obtaining and releasing, and the structure of calcium pump changes accordingly. Chikashi Toyoshima (Institute of Molecular and Cellular Biosciences of the University of Tokyo) first discovered this structural change and analyzed the calcium pump structure in nine states.

His research results were published in the British journal Nature in 2000, 2002 and 2004. In view of this series of outstanding achievements, Professor Toyoda was awarded the Asahi Prize in 2009.

4. Discovery of new magnetic materials on meteorites

Every year, thousands of tons of meteorites fall to the earth. Although their surfaces are burnt black, their internal metal and mineral components remain unchanged, so they are called "fossils" in space. It provides powerful evidence for human beings to understand the mysteries of the solar system.

Masato Kotsugi, JASRI) of Japan Synchrotron Radiation Research Institute used the Photoelectron Emission Microscope (PEEM) on BL25SU beam line of SPring-8 to analyze the structure of iron meteorites. Iron meteorite is composed of α phase rich in iron and γ phase rich in nickel. Dr. Xiao Shan confirmed that there is a nano-scale mineral layer at the interface between iron and nickel, which is called Tetrataenite. However, it does not exist on the earth and will become an excellent new magnetic material. Dr. Xiao Shan further analyzed the characteristics of Tetrataenite, which is composed of 50% iron and 50% nickel, and the iron and nickel atoms are alternately arranged, which is a regular periodic crystal structure. It produces a kind of hard magnetism, that is, the magnetization direction will not change easily. Famous hard magnetic materials include permanent magnets and materials used in engines of hybrid vehicles.

Another important discovery of Dr. Xiao Shan: Tetrataenite will be a potential substitute in hard disk manufacturing. Platinum is an indispensable material for the next generation hard disk, but it is a rare metal, and its price is rising. At present, the demand for platinum has exceeded its production capacity. About 2 tons of platinum is used in global hard disk production every year. If Tetrataenite synthesized by iron and nickel can be used as hard disk material, the consumption of platinum will be greatly reduced, thus promoting resource conservation and low-cost production of hard disks.

Chiharu Mitsumata (Toho Kyu University) of Tohoku University in Japan is carrying out basic research on the synthesis of Tetrataenite.

As a result, Dr. Koyama and Professor Sanyan won the second place in Dubose-Crouse Award (international metallic graphic contest) in 2010.

　5. Successfully developed all-solid-state safety battery by nanotechnology.

Professor Hiroshi Kitagawa (Kyoto University) of Kyoto University and Dr Rie Makiura (Kyushu University) of Kyushu University have studied nano-scale silver iodide (AgI) particles. They proved for the first time in the world that it is possible to realize stable solid electrolyte at room temperature. This research achievement is highly valued because of its great development potential. The paper was published in the British scientific journal Nature Materials in May 2009.

6. the three-dimensional structures of Rab27B and Slac2-a are analyzed.

In 2004, Dr. Mitsunori Fukuda (Tohoku University) of the Graduate School of Life Sciences of Northeastern University clarified the transmission mechanism of melanin in melanocytes at the molecular level. In 2008, in cooperation with Shigeyuki Yokoyama of RIKEN Institute of Physical Chemistry, he successfully analyzed the three-dimensional structures of Rab27B and Slac2-a in BL41XU Experimental Station of Structural Biology on SPring-8. Their structural data will greatly promote the research and development of new skin whitening products and drugs to prevent white hair.

7. The new chewing gum Pos-Ca can effectively prevent tooth decay.

Dr. Tomoko Tanaka (the Health Science Laboratory of Ezaki Glico Co., Ltd.) found that calcium phosphate oligosaccharide supported the remineralization of teeth, which promoted the appearance of new chewing gum with calcium phosphate oligosaccharide (Pos-Ca).

8. Research and development of new drugs against influenza virus

Influenza virus consists of eight RNA genes, and there are two types of spike proteins on the surface of virus particles: hemagglutinin (HA) and neuraminidase (NA). Because of its simple structure, the virus cannot replicate itself. However, they can be skillfully replicated by using the replication system of human cells after invading human host cells.

HA, like a key, can invade the human body after combining with glycoprotein on the cell surface. NA plays an important role in the separation and release of progeny virus from cells, and is an enzyme that helps the virus infect other bacteria. The amino acids that make up the above two proteins are prone to mutation. So far, scientists have discovered 16 kinds of HA and 9 kinds of NA proteins. These protein are arbitrarily combined into various types of influenza viruses (H1N1–H16N9). For example, influenza A H1N1, which was prevalent in 2009, and H5N1 virus, avian influenza, which became prevalent in 1997.

Influenza virus encodes 10 kinds of proteins, among which RNA polymerase is very important in virus gene replication. It includes three subunits: PA, PB1 and PB2. When one of them is lacking, RNA polymerase loses its enzyme function and the virus cannot replicate. Therefore, if we can determine the three-dimensional structure of these three subunits, we can block the function of RNA polymerase.

In July 2008, Dr. Sam-Sam (Graduate School of Nanobioscience, yokohama city university) successfully analyzed the combined structure of PA and PB1, and analyzed the enzyme structure related to virus replication, which will accelerate the research and development of new antiviral drugs. It is not far away to realize the wish that people don’t have to worry about the flu in winter.

9. Reveal the secret of solar system formation by analyzing comet dust.

The American Stardust Project, 1999-2007) collected scattered dust samples of comet Wilder II (81P/Wild) and brought them back to Earth. It is expected that by analyzing these samples, information about the origin of comets and the entire solar system 4.6 billion years ago can be obtained.

Dr. Tomoki Nakamura (Kyushu University) of Kyushu University has conducted in-depth research on comet dust. He used the X-ray diffraction experimental device of BL37XU on SPring-8 and the synchrotron radiation facility of KEK to analyze and determine the crystal types and abundance ratio of dust. After that, Professor Akira Tsuchiyama (Osaka University) used the CT scan of BL47XU to visualize the internal structure of comet dust.

Dr. Nakamura found that "meteorite chondrules" originated from comet dust outside the solar system, so they can no longer be explained by the traditional model of solar system formation. "Meteorite chondrules" are the main components of ancient meteorites, rich in magnesium, silicon and a small amount of iron. The doctor believes that the migration of "globules" occurred in the primitive solar system composed of dust disks; However, he said that the analysis accuracy of at least 20 samples will be improved to obtain statistically significant conclusions. He will also continue to carry out comet meteorite dating and determine the migration time. It is expected that a new solar system formation model will be established soon.

10. Nanotechnology promotes the innovation of "new materials"

The shape characteristics of fullerenes discovered in 1985-containing 60 carbon atoms, like a football-have aroused widespread concern in the scientific community. In 1991, columnar carbon nanotubes were discovered. In January, 2008, Associate Professor Kitura & Hisa Nori Shinohara (Nagoya University) of Nagoya University successfully synthesized a nano-scale metal wire.

Carbon allotropes: diamonds and graphite, fullerenes and carbon nanotubes.

Pure gold is prone to oxidation reaction, but a very thin nanowire can exist stably in the air because nano-scale materials have a unique stable structure. In order to observe the internal structure of nanotubes, Associate Professor Bei Puliang conducted solid soft X-ray spectroscopy experiments at BL25SU experimental station in Spring–8. He observed that the absorption of Er by X-rays was unique, thus confirming that ErCl3 line was formed in carbon nanotubes.

Carbon nanotubes in fullerenes look like pods.

ErCL3 structural model (Er atoms in red and CL atoms in green)

Professor Tian Zhuo (University of Tokyo/RIKEN) of Tokyo University and Institute of Physical Chemistry is regarded as the most imaginative and productive polymer chemist in the world. In recent years, he took SPring-8 as an important research tool, and first successfully determined the structure of a new type of conductive graphite nanotubes. Then, he showed with solid evidence that the hydrophilicity and hydrophobicity of graphite molecules were closely connected in hydrophobic groups, forming tubular spiral molecular pairs. In addition, he also successfully designed a liquid crystal phase with short intermolecular programs. Both research results were published in the Journal American Chemical Society in 2008. In 2009, the design of "bicontinuous cubic liquid crystal materials in discoid molecules" was published on the cover of the magazine of American Chemical Society, and he also won the Polymer Chemistry Award of American Chemical Society.

11. Develop earthquake observation technology.

With the joint efforts of Tokyo Institute of Technology, Japan Agency of Marine-Earth Science and Technology and Japan Synchrotron Radiation Research Center (JASRI), it is found that the deepest part of the earth’s core is made of iron with hexagonal close-packed structure. The state of metallic iron under ultra-high pressure and ultra-high temperature conditions is similar to the state of the earth’s core simulated by ultra-high pressure and ultra-high temperature. Scientists used SPring-8 high-brightness X-ray to observe the changes of single crystal structure of metallic iron, and found for the first time that the hexagonal close-packed structure was stable under extreme conditions of high temperature and high pressure. The analysis of the crystal structure is helpful to the analysis of earthquake observation and greatly strengthens people’s understanding of the formation and development of the core. This achievement was published in the American journal Science on October 15th, 2010.

12. Analyze the gel mechanism of self-assembly from the molecular level.

Recently, a joint research group of The University of Kitakyushu and JARSI announced that the molecular structure of the solvent in the gel state was analyzed on the BL03XU Advanced Soft Materials and BL40B2 Structural Biology II Experimental Station by using SPring-8 high-brightness synchrotron radiation. The research results benefit from organogelator (low molecular weight compound). As long as 1% solvent is added to it, the whole solvent will gel, which will greatly help to prevent environmental pollution caused by offshore oil spill. The paper was published online in the October 2010 issue of Polymer Journal.

Sixth, look forward to the future

The resolution of traditional optical microscope is limited by the wavelength of light, while the wavelength of X-ray is 10,000 times shorter than that of visible light, and the resolution reaches the atomic level, which means that the three-dimensional structure of a single atom in matter can be observed. X-ray is widely used in medical treatment, life science and material science. However, the light generated by X-ray light sources (including synchrotron radiation) is not uniform and the wave fields are inconsistent. Laser can produce uniform light by using a pair of mirrors. This urges scientists to make every effort to explore a new technology to realize a mirrorless laser, that is, XFEL: X-ray Free Electron Laser (XFEL). XFEL is an X-ray that combines the characteristics of free-electron laser. It is called the most promising new light source in the future with the most scientific exploration and discovery value. It is also called "dream light source" and "new dawn of the scientific era". It has the dual characteristics of laser and radiation light, and can work in the whole X-ray band. It is much better than the third generation synchrotron radiation light source in brightness, coherence and time structure, and is internationally recognized as one of the feasible technical routes of the "fourth generation light source".

The United States, Europe and Japan have successively developed XFEL, and raised it to the height of national strategy to deploy and implement it. LCLS(Linac Coherent Light Source, Stanford Linear Accelerator Center, USA), the first X-ray free electron laser device in the world, came out in 2009. The European Free Electron Laser Facility (European XFEL) is jointly participated by DESY of Germany and 11 other European countries. The core project is a 3.4-kilometer underground tunnel, which was officially started on July 1, 2010. It is expected to be completed in 2014 and the first scientific experiment will be conducted in 2015.

SPring-8 has already started the prefabrication and research of XFEL, and the accelerator prototype has successfully produced the first laser beam. In 2006, the XFEL project started. At present, the 700-meter-long 8GeV X-ray free electron laser device is under final construction and is expected to be put into operation in fiscal year 2011. exist

2.XFEL facilities

SPring-8′ s X-rays can produce light 10 billion times brighter than the sun, while XFEL produces light 1 billion times brighter than SPring-8, and the pulse is 1000 times shorter than the existing X-ray source. The higher brightness light source enables scientists to observe the three-dimensional structure of atoms and their ultra-fast motion more realistically.

Design parameters:

Electron beam energy: 8 GeV

Electron beam diameter: 40 um

X-ray wavelength: > 0.06 nm

X-ray peak power: 5 GW

X-ray pulse length: < 100fsec

X-ray peak brightness: 1033 photons/s/mm2/mrad2/0.1% b.w. 。

The original quality of electron beam determines the quality of free electron laser. Scientists have specially designed an ultra-high voltage thermal electron gun, which uses a single-crystal cerium-hexabromoboride cathode (CEB 6) to emit a fine, highly collimated and stable electron beam. Then, it is transported into the electron beam compression system, and the peak current will be strengthened to several thousand amperes.

The electron beam energy is rapidly increased to 8GeV by a C-band linear accelerator, and then transported into a vacuum undulator to generate intense XFEL radiation.

3. Create new technologies

Coherent X-ray imaging technology: Microscopic images of various materials at atomic level can be obtained.

Imaging process: X-ray laser → sample → coherent scattering mode → phase recovery → clear structure image.

XFEL’s ultrashort pulse can detect the ultrafast motion of matter in femtosecond.

Protein Structure Analysis: The analysis of new materials will surely lead to the birth of new functional products in biology and medicine.

Living cell biology: Real-time data acquisition will open a new way for the study of living cells.

Nanotechnology: Ultra-short wave XFEL will help to create new functional materials.

With XFEL, scientists can observe extreme phenomena in astronomy, plasma science and basic physics.

The Institute for Molecular Science, Niigata University, Nagoya University and JASRI/RIKEN of the National Research Institute of Japan jointly studied the intense ultraviolet free electron laser irradiated to argon atoms, and successfully analyzed the specific process of multi-electron emission.

In order to accurately measure the fluctuation in free electron laser, scientists analyzed all the electronic energy of argon atom irradiated by laser pulse at the speed of 20 pulses per second. They found that the absorption of electrons and multiphotons only occurs when the light intensity is very high, and clarified the importance of resonance state in multiphoton absorption. The research results show that the research of nano-science, nano-technology and material preparation can be promoted by using X-free electron laser on the basis of selecting appropriate laser wavelength and corresponding resonance conditions. The paper was published in american physical society’s scientific journal Physical Review Express on September 24th, 2010.

　　Cctv newsOn October 27th, the Commission for Discipline Inspection of Xiangtan City, Hunan Province reported the investigation and handling of the illegal payment of subsidies for Tianjin by the No.1 Commercial Office, the Vegetable and Meat Office, the Catering Office, the Electronic Office, the Light Industry Office and the Machinery Office. Twelve leading cadres at or above the deputy division level involved in the case violated the relevant regulations and paid subsidies for Tianjin in the name of duty subsidies, subsidies for maintaining stability and conference fees for restructuring work during the "two sessions", and were put on file for review and punished by party discipline and discipline.

　　How to issue subsidies, subsidies or benefits is not a violation of discipline? Let’s make clear the difference between these concepts &mdash; &mdash;

　　salaryRefers to the labor remuneration paid by the employer to the laborer in the form of money according to the relevant provisions of the state or the labor contract.

　　allowanceRefers to the form of wage supplement to compensate employees for labor consumption and extra expenses of living expenses under special conditions.

　　subsidyIt is a variety of subsidies paid to ensure that the wage level of employees is not affected by price increases or changes.

　　Simply put, allowances and subsidies are included in wages. There is no difference between subsidies and subsidies in essence, but subsidies are subsidies for daily living expenses, focusing on life; The allowance is the compensation for extra and special labor consumption, focusing on productivity.

　　How to pay the allowance without violating the rules?

　　high subsidies

　　According to the Management Measures for Heatstroke Prevention and Cooling Measures revised in 2012, if the employer arranges the workers to engage in outdoor open-air operations in high-temperature weather above 35℃ and cannot take effective measures to reduce the workplace temperature below 33℃, it shall pay high-temperature allowance to the workers.

　　Overtime allowance

　　Overtime pay is a legal obligation set by the law to the employer, but overtime allowance is different. It is a welfare system set by the employer to the employees of the enterprise. There is no mandatory requirement for overtime allowance by the law. The employer can decide whether to set up and implement the overtime allowance system according to the business characteristics and the needs of the enterprise.　

　　Overtime allowance shall be subject to the principle of "no refund for more and no compensation for less"When the actual overtime pay is higher than the overtime allowance, the employer shall pay it according to the actual overtime pay; When the actual overtime pay is lower than the overtime allowance standard, the employer can pay according to the overtime allowance standard stipulated in the enterprise.

　　The question is, is there any overtime allowance for civil servants who work overtime? According to the provisions of Article 76 of the Civil Service Law, if civil servants work overtime outside the statutory working days, they shall be given corresponding compensatory time off, unless otherwise specified. Except for police, court and procuratorate staff.

　　In other words, civil servants (except the public security system) do not pay overtime pay for overtime work, but can arrange compensatory time off; The staff of police, courts and procuratorates can be subsidized according to the regulations if they work overtime.

　　Night shift allowance

　　Night shift allowance is an allowance standard to ensure the health of workers engaged in production at night and arouse the enthusiasm of frontline workers. Night shift usually refers to the situation in which an enterprise arranges workers to work for 2 hours or more from 22: 00 to 6: 00 the next day.

　　With regard to the night shift allowance, the state has not issued any relevant regulations, and various localities have issued corresponding standards, but the situation is uneven. Some provinces and cities, such as Jiangsu, Shandong, Fujian and other places, still implement the standards of the 1990s. Some provinces and cities, such as Tianjin, adjusted the night shift allowance standard in time according to social development.

　　Maternity allowance

　　Maternity allowance is the salary paid by maternity insurance fund to female employees during childbirth, that is, maternity leave salary. During the period of maternity leave, the unit may not pay their wages, and the wages during this period will be paid by the maternity insurance fund.

　　If the maternity allowance is higher than my maternity leave wage standard, the employer shall not deduct it; if the maternity allowance is lower than my maternity leave wage standard, the difference shall be made up by the employer. The amount of maternity allowance is directly related to the average monthly salary of workers in the unit where they work last year. The calculation method is:Maternity allowance = (the average monthly salary of employees in the previous year) ÷30× the specified number of holiday days.

　　old age allowance

　　Old age allowance is a social security system for the elderly. At present, most provinces in China have introduced the subsidy policy of old age allowance, and most provinces issue old age allowance or nutrition fee to local registered elderly people over 80 years old.

　　What other benefits are available?

　　In July 2014, the All-China Federation of Trade Unions issued the Notice on Strengthening the Management of Funds Revenue and Expenditure of Grass-roots Trade Unions, proposing that grass-roots trade unions can distribute a small amount of holiday condolences to all employees on holidays. Not long ago, the All-China Federation of Trade Unions issued the Supplementary Notice, which made more explicit provisions on some practical issues. For example, for the first time, it was made clear that "New Year’s Day" refers to seven statutory holidays stipulated by the state, including New Year’s Day, Spring Festival, Tomb-Sweeping Day, Labor Day, Dragon Boat Festival, Mid-Autumn Festival and National Day.

　　According to the regulations, the following benefits can be paid:

　　These expenses can’t be!

　　At the same time, it is clear that the following expenses cannot be:

　　1. Buy shopping cards, vouchers, etc., and engage in activities such as treating guests and giving gifts;

　　2, illegal spamming allowances, subsidies, bonuses;

　　3. Pay for high-consumption entertainment and fitness activities;

　　4. Set up a "small treasury" in violation of regulations;

　　5. Incorporate the trade union account into the unit administrative account, which makes the trade union expenditure out of control;

　　6. Interception and misappropriation of trade union funds;

　　7. Participate in illegal fund-raising activities or provide economic guarantee for illegal fund-raising activities;

　　8. Reimbursement of expenses unrelated to trade union activities.

In the era of knowledge economy, whether it is the change in the proportion of intangible assets among the 500 companies in the Standard & Poor’s Index of the United States, or the frequent patent wars on smart phones and a large number of patent acquisitions in recent years, it shows that patents have become an important asset of enterprises, a key factor of production, a protagonist of trade, a sharp weapon of competition, and a source of power to drive enterprises to last forever. By comparing and measuring the scale and quality of patent portfolio owned by enterprises, we can clearly and accurately analyze their technical strength, innovation ability and even competitiveness.

The patent strength rankings based on a series of objectively quantified patent statistical indicators, such as the Wall Street Journal Patent Scorecard, the IEEE Patent Strength Scorecard, and the Thomson Reuters Top 100 Innovative Institutions Ranking, provide a common comparison stage for all kinds of innovative entities at the technical level, which will cause great repercussions after each release. For the public, we can learn about the technology leaders and innovation benchmarks in the industry, while for enterprises, the shortlist is an excellent publicity. The following is a brief introduction to the above three categories of leaderboards based on the public information on the Internet.

I. Patent Scorecard of The Wall Street Journal

(1) Introduction

The Wall Street Journal (WSJ) publishes the technical strength rankings and stock market data of companies and research institutions in a certain industry in the form of PatentScorecard in the financial & investment column every Tuesday, and the same content is subsequently published in the market data center section of the online website of The Wall Street Journal. The patent scorecard mainly focuses on the patents in an industry, and the statistical indicators involve patent authorization, industrial influence, R&D intensity, technical intensity, scientific intensity, etc., and ranks the institutions in an industry according to technical intensity and scientific intensity, and gives the comparative results of patent strength after comprehensively considering the scale and quality of patent portfolio, and the statistical results are updated every 13 weeks. The patent scorecard covers 18 industries, including aerospace and national defense, automobiles and transportation, biology, chemistry, consumer electronics, personal consumer goods, comprehensive industries, electronic devices, energy and environment, food and beverage and tobacco, heavy industry equipment, industrial parts, raw materials, information technology, medical devices and services, pharmaceuticals, semiconductors and communications. While giving the ranking results of patent portfolio, The Wall Street Journal also correlated the patent scorecard data with Dow Jones financial data, and gave the comparative results of the industrial influence, R&D intensity, patent authorization, stock market and the overall level of an industry.

The data of the patent scorecard of The Wall Street Journal is provided by The Patent Board. The Patent Committee actually belongs to ipIQ Company (ipIQ refers to intellectual property, intelligence quota; Now it is renamed ip IQ Global Company), and its predecessor is CHIresearch. Founded in 1968, CHI has been devoted to the research and analysis of scientific and technological innovation indicators, and has created a series of patent indicators, especially the precedent of statistical analysis of patent citations. CHI’s patent index system is introduced and adopted in the American Science and Engineering Index compiled and published by the National Science Foundation of the United States and the Patent Manual in the OECD series of science and technology index manuals. CHI is an absolute international leader in the field of patent measurement, and the patent scoreboard is its distinctive research achievement and has been registered as a trademark. In November 2004, CHI Company was merged and renamed ipIQ Company.

The patent scorecard was first published in BusinessWeek magazine on August 3rd, 1992. Before 2007, the patent scorecard was published in Businessweek and MIT’s Technology Review every year. Since 2007, The Wall Street Journal and the Patent Committee have become partners and regularly publish patent scorecards in The Wall Street Journal in the form of patent portfolio rankings.

In addition to publishing the ranking results of industrial patent portfolio in cooperation with The Wall Street Journal, the Patent Committee also published The Global Patent Scorecard, The Patent Board 500 Scorecard and the University Scorecard.

(II) Main indicators

Patent scorecard indicators include four aspects and six indicators:

1. Quality: including technical strength and industrial influence indicators. Technical strength is the overall evaluation result of an institution’s patent portfolio strength by combining quantity and quality factors, and it is one of the ranking bases of patent portfolio. Industrial influence refers to the influence of an institution’s patent portfolio on subsequent technological innovation, which is calculated by the cited data of patents.

2. Quantity: The index of patent authorization refers to the number of American patents granted in a certain institution during the statistical period.

3. Science: including indicators of scientific intensity and research intensity. Scientific intensity is used to measure the extent to which enterprises use scientific research results to construct their patent portfolios, and it is also one of the ranking criteria of patent portfolios. Research intensity refers to the number of patents whose scientific relevance is higher than the industry average in an institution’s patent portfolio.

4. Speed: innovation cycle index, which is used to measure the old and new degree of the existing technology on which the patent or patent portfolio is based.

Second, the IEEE patent strength scorecard

(1) Introduction

On October 23rd, 2013, IEEE SPECTRUM published the 2013 IEEE (American Institute of Electrical and Electronics Engineers) Patent Power Scorecard. Patent strength scorecard is the result of objective and quantitative analysis of American patents of more than 5000 leading companies, academic institutions, non-profit organizations and government agencies around the world, which involves aerospace and national defense, automobiles and parts, biomedicine, chemistry, communication network equipment, communication network services, computer equipment and storage, computer software, computer systems, comprehensive enterprises, electronic products, government agencies, medical instruments, scientific instruments and semiconductor equipment manufacturing. The patent strength scorecard ranks according to the patent strength index, which comprehensively considers the quantity and quality of the patent portfolio, among which the patent quality is

It is reflected by the indicators related to patent growth, technological influence, technological originality and technological diffusion. As the scale of patent portfolio weighted by quality is adopted as the measurement basis, the technical strength of an institution can be measured as a whole, which is the best barometer to measure the technical R&D and innovation strength of various institutions. The list is published once a year, and the list in 2013 is the seventh release. The 2012 patent strength scorecard list was also published on Forbes website.

The patent strength scorecard is provided by 1790 Analytics. The founder of the company is Dr. Anthony Breitzman, who used to be the vice president of CHI and a world-renowned expert in science and technology assessment. Dr. Anthony Breitzman founded 1790 Analytical Company after he left CHI. Dr Patrick Thomas, head of patent analysis business and Chip D&rsquo, head of business development; Angelo is a former CHI researcher.

(II) Main indicators

The patent strength index in the IEEE patent strength scorecard is a comprehensive index after combining the number of patents and their growth, technical influence, originality and popularity. Its calculation formula is: patent strength index = number of patents × patent growth index × corrected technical influence index × technical originality index × technology diffusion index. Taking the patent strength index in 2012 as an example, the meaning of each parameter is:

1. The number of patents refers to the number of patents granted in the United States in 2012.

2. Patent growth index, which is used to reflect the patent activity of an institution, and then reflect the innovation activity of an institution. The calculation method is: the number of patents granted by an institution in the United States in the latest year (2012) divided by the average number granted each year in the previous five years (2007-2011).

3. The corrected technology impact index reflects the influence of an institution’s patent portfolio on the subsequent technology development. The calculation method is as follows: first, calculate the basic value of the technology impact index, and then correct it according to the self-citation rate (to eliminate the influence of extreme self-citation). The basic value of technology impact index refers to the number of times that all authorized patents of an institution were cited by all authorized patents in the United States in the last year (2012) in the first five years (2007-2011), divided by the average number of times that all authorized patents in the same period and in the same field as the patent portfolio of the institution were cited by all authorized patents in the United States in the last year.

4. The technical originality index reflects the breadth of the patented technology (i.e. cited patents) cited by an institution’s patent portfolio. Generally, improved inventions tend to refer to existing technologies from a single field, while important original inventions tend to combine patented technologies from different fields to form new inventions.

5. The technology diffusion index, also known as the technology popularization index, is similar to the technology originality index, but it reflects the breadth of the patented technology (i.e. cited patents) cited by an institution’s patent portfolio. The greater the technology diffusion index, it means that the patent application of an institution is popular, which has a large impact on the subsequent technological innovation.

Third, Thomson Reuters Global Top 100 Innovative Institutions Ranking

(1) Introduction

Thomson Reuters’s "Top 100 Innovative Institutions in the World" is the ranking result of the most innovative institutions in the world based on a series of patent indicators, which is published by Thomson Reuters Intellectual Property and Technology Division on its website. It has been published once a year since 2011 and has been published three times so far. According to the data of the top 100 innovative institutions in the world in 2013, according to the number of institutions on the list, there are 46 institutions from North America (45 from the United States and 1 from Canada), 32 institutions from Asia (28 from Japan, 3 from South Korea and 1 from Taiwan, China) and 22 institutions from Europe (including 12 from France and 4 from Switzerland). Although China leads the world in the number of patent applications, none of China companies are on the list due to the lack of patent quality and technical influence.

(II) Main indicators

The selection method of Thomson Reuters’s "Top 100 Global Innovation Institutions" is based on four criteria:

1. The total number of patents refers to the number of DWPI(Derwent World Patents Index) basic patents of an institution in recent three years. This basic patent refers to the patent that publicly released a new technology for the first time in the DWPI patent family.

2. The success rate of patent authorization refers to the number of patents published by an institution in the last three years divided by the number of patents authorized in the last three years.

3. The globality of patent portfolio refers to the number of four-party patents owned by an institution. The Quartet refers to China National Intellectual Property Administration, China, the European Patent Office, the Japanese Patent Office and the United States Patent and Trademark Office.

4. Patent influence based on citation refers to the number of times an institution’s patents have been cited by others in recent five years (excluding self-citation).

summary

Comparing the above three rankings comprehensively, the common point is that, while reflecting the scale and activity of innovation through patent quantity data, it is more important to introduce patent quality data such as technical influence, diffusion, originality and globalization to reflect the benefits of innovation, thus truly and reliably reflecting the comprehensive technical strength and innovation ability of enterprises. Patent ranking itself is only a means of comparison and a yardstick to measure innovation output. Its real strength lies in highlighting that innovation is the core factor driving development in the era of knowledge economy. Take the top 100 innovative institutions in the world as an example. For three consecutive years, the listed institutions are better than those involved in the Standard & Poor’s 500 Index in various indicators: the annual share price growth is 4% higher, the market value-weighted sales growth rate is 2% higher, and the new job growth rate is 0.81% higher. At the top of the wave, these listed companies are deducing realistic cases of innovation-driven development to the society with objective and detailed data.

-building a science and technology innovation center with global influence, creating a creation center, a transformation center and a protection highland for high-value patents.

　　Be the vanguard of reform and opening up and the pioneer of innovation and development. Over the years, Shanghai has continued to increase government guidance and investment, improve public welfare services, promote the transfer and transformation of patents, and build a creative center, transformation center and protection highland for high-value patents. Here, the trunk passenger plane C919 with completely independent intellectual property rights appeared in the sky, and China’s first lunar rover "Yutu" walked in the Moon Palace … The vision of an Asia-Pacific intellectual property center city is slowly being paved. How to grasp this great historical opportunity, better embrace innovation and promote transformation is a problem that everyone in Shanghai is thinking about. High-value patent, which contains the internal demand of continuous innovation and development, has become the "Shanghai password" to activate the driving force of innovation and win the initiative of development.

　　"Having a large number of high-value patents is a concentrated expression of a city’s innovation ability and competitiveness. One of the important symbols of Shanghai’s construction of a globally influential science and technology innovation center should be the creation center, transformation center and protection highland of high-value patents. Therefore, the cultivation of high-value patents is an important foundation and support for promoting the construction of a globally influential science and technology center in Shanghai. " Lu Guoqiang, director of the Shanghai Intellectual Property Office, said that in recent years, with the goal of building an Asia-Pacific intellectual property center city, Shanghai has vigorously implemented the intellectual property strategy, played a policy-oriented role, deepened reforms in all aspects of patent creation, application, protection, management and service, and strived to improve the quality of patents and deepen the "Shanghai value".

　　Encourage innovation and create value.

　　Large planes soar in the blue sky, with high-value patents as wings. This sentence is not a metaphor, but a true portrayal of the status of high-value patents in the "big country". C919 has adopted a large number of new technologies, new materials and new components from airframe structural parts to airborne system equipment, from nose test to tail composite material application, among which 102 key technological breakthroughs such as thrust reverser technology and active control technology have been made, which shows the overall scientific and technological strength and "China wisdom" of China’s aviation industry. Comac Shanghai Aircraft Design & Research Institute submitted 453 China patent applications, such as "fairing structure suspended in aircraft with wing crane layout" and "suspension structure with integrated propulsion system", around the nose, fuselage, wing and wing crane engine of C919, which marked a new height of "Creation by China" and attracted widespread attention from the international community. At present, C919 large passenger aircraft has 23 domestic and foreign users, including China International Airlines, and the total number of domestic and foreign orders has reached 570. International customers, such as General Electric Leasing Company of the United States, have become "buyers" of C919. Nie Xin, head of intellectual property of COMAC Shanghai Aircraft Design and Research Institute, said that COMAC Shanghai Aircraft Design and Research Institute has always insisted on quantity layout and quality win, promoted patent value orientation within the institute, promoted high-level patent creation, high-quality evaluation and high-value authorization, and built a competitive advantage with a high-value patent portfolio system. "We always insist on improving the research and development level from the forefront of innovation, establishing ourselves through high-value patents in foreign cooperation, and testing water through patents in new fields.With high-value patents in the domestic and foreign markets, through the patent value to highlight the value of the institute itself. "

　　If large enterprises and institutions with strong strength can "multiply" the accumulation of a large number of high-value patents, then small and medium-sized enterprises with flexible innovation methods can "play around" few but fine high-value patents, which is tantamount to "making an index". Shanghai Dianba New Energy Technology Group Co., Ltd. (hereinafter referred to as Dianba New Energy) is the best among the latter. Gu Qing, general manager of Electric Bus New Energy, told the reporter that at present, the company has 9 invention patents, 55 utility model patents and 2 design patents. These patent pieces are "swords", and the value they realize can be called "a small amount contains great energy". According to reports, the company’s patent for "an electric bus system" was submitted and granted in 2004, and the international patent application submitted through the Patent Cooperation Treaty (PCT) entered 21 countries and regions such as the United States, the European Union, Japan and Singapore. The patented technology can replace the battery for electric buses within 4 minutes, which has been widely used in Beijing Olympic Games, Shanghai World Expo and Guangzhou Asian Games, and has withstood the test of high density, large passenger flow and extreme weather. By the end of 2016, the company had achieved sales of about 200 million yuan only by selling charging and replacing power station equipment products converted from the above patents. Gu Qing said that the company has always adhered to development, research and development, and layout. Not only did it lay out early patents before research and development, but it also laid out improved patents in the process of technological improvement, inciting a vast market with a small number of patents with high value.

　　"High-value patents should first be high-quality patents, and the patented technology should be advanced and versatile. At the same time, the quality of patent writing is high and the scope of patent protection is wide." Lv Guoqiang believes that measuring whether a patent is a high-value patent should be multi-dimensional, and the technical level, writing quality and layout fields are indispensable. The "gestation" process before the birth of a patent determines whether it is a "fine variety" or a "weed", and the positive guidance for the creation of high-value patents has become one of the working hands of the Shanghai Intellectual Property Office. Lv Guoqiang introduced that in 2012, the Shanghai Patent Subsidy Measures was revised, which changed the original patent application fee and authorization fee from "full funding" to "partial funding" and changed from "funding upon application" to "funding after authorization", and focused on invention patents and foreign patents, effectively improving the quality of patents. At present, the number of effective invention patents in Shanghai has reached 90,000, and the maintenance rate of effective invention patents for more than five years ranks third in the country.

　　Strengthen application and realize value.

　　"The unit hired me as a manager, not to let me just queue up at the window to pay the annual fee." According to Cheng Leilei, head of intellectual property in the Scientific Research Department of Zhongshan Hospital affiliated to Fudan University, to tap the high value of patents, patent managers must first recognize their own value. Cheng Leilei told reporters that intellectual property managers in colleges and universities should give full play to their subjective initiative, not be satisfied with procedural "optional actions", but should assist front-line researchers to find the right direction of research and development, help them tap the value of achievements, and realize the effective transformation and application of patents. "Medical care is a knowledge-intensive industry with rich patent resources, but the patent technology transfer conversion rate of medical institutions in China does not match the existing technical level, and there is a significant gap with developed countries. To make the sleeping patent value alive, we must catch up, take various effective measures, quickly and effectively transform the latest achievements of medical research into clinical medical technologies and products, feed back the actual situation of clinical research to the laboratory, and create a’ two-way channel’ from laboratory to ward and from ward to laboratory, so as to popularize and socialize medical research achievements. " Cheng Leilei said that Zhongshan Hospital attaches great importance to the transfer and transformation of patents. As early as 2008, it set up a results management section in the hospital’s scientific research department to be responsible for the declaration, management and transformation of intellectual property projects. In order to maximize the value of the results, the hospital is managed by the scientific research department in a unified way, exploring valuable achievements from various scientific research projects at all levels, analyzing and sorting out the patented and patentable achievements, and avoiding the low-value patents that are patented for the sake of patents.Ensure timely application, authorization and transformation of truly valuable and high-value projects. At present, Sun Yat-sen Hospital has established six transformation modes, namely, directly transforming patents into enterprises, relying on technology transfer institutions of universities to transform patents, establishing cooperative institutions with local governments, jointly establishing cooperative institutions with enterprises to transform patents, transforming patents through university science parks and transforming patents through national engineering centers. According to the characteristics of different projects, the specific conditions and requirements of licensees or transferees, each patent can be operated flexibly and in multiple ways according to local conditions, so as to maximize its potential.

　　"The value of a patent lies not only in its meaning of property rights, but also in people." Feng Hongbin, head of the intellectual property expert group of Shanghai Institute of Aerospace Technology, believes that the key to cultivating high-value patents is to change ideas and cultivate awareness. As a space backbone base with multiple models of "missile, arrow, satellite and ship" and integrated military and civilian development, Shanghai Aerospace established the Shanghai Space Administration Patent Office (the predecessor of the Shanghai Space Administration Patent Center) as early as 1985, which is the only national defense patent agency in Shanghai. On this basis, the Intellectual Property Center of Shanghai Institute of Aerospace Technology was established in 2013 to realize the transformation of intellectual property management from macro management of units to fine management of projects. The relevant person in charge told the reporter that while undertaking the task of national defense and military industry, Shanghai Aerospace has implemented the national policy of "combining the military with the people", taking constantly adapting to and meeting the needs of the development of national defense science, technology and industry and the development of national economy as the fundamental starting point, focusing on national major scientific and technological special projects such as manned spaceflight, lunar exploration project and high marks, as well as strategic emerging industrial projects such as photovoltaics and lithium batteries, and fully tapping the core technological value of military units. Shanghai Space Power Research Institute, a subsidiary of Shanghai Space Power Research Institute, undertakes the task of developing space power system and related stand-alone machines, and at the same time, vigorously develops civil new energy technologies such as power lithium-ion batteries, and promotes the transformation of innovation achievements. It has invested 15.1 million yuan in Shanghai Space Power Company with two patents for power lithium-ion batteries. Shanghai Aerospace Equipment Manufacturing General Factory has developed a series of friction stir welding equipment in combination with civil needs.It has provided products for dozens of domestic enterprises, with annual sales exceeding 40 million yuan. At the beginning of the lunar rover project, which is well-known as "Yutu", the intellectual property work plan and funds were included in the unified model management. The model team submitted a total of 55 patent applications, and established a patent database containing more than 1,500 domestic and foreign patent documents, which was supplemented and updated regularly, supporting the subsequent deep space exploration argumentation such as Mars, and the patent achievements were expanded and applied to the civil field, making the patent value everywhere from "heaven" to "human".

　　"High-quality patents can become veritable high-value patents by achieving considerable economic and social benefits through transformation and implementation, licensing transfer, investment operation, and litigation rights protection." Lu Guoqiang said that the Shanghai Intellectual Property Office has guided enterprises and institutions to pay attention to the cultivation of high-value patents by helping enterprises and institutions to transfer high-value patent achievements at high prices. Shanghai has set up a patent award for invention and creation, which is included in the municipal government’s award projects. It is evaluated once every three years, and more than 40 patent projects are awarded each time, and each project can be awarded a maximum of 100,000 yuan. The award-winning project not only has high patent quality, but also has been transformed and implemented, with good economic benefits, and is a veritable high-value patent. At the same time, the Shanghai Intellectual Property Office has vigorously promoted the construction of patent alliances. At present, patent alliances have been established in the fields of digital TV, motors and systems, medical devices, oil exploration equipment, etc. Leading enterprises have set up patent pools for related core patents, and carried out patent licensing, operation and collaborative research and development, so that high-value patents of different units can be interconnected and full of vitality.

　　Reform service and dig deep into value

　　"Roads and bridges are connected, and all industries are prosperous." In the view of Shan Xiaoguang, a professor at Tongji University’s Shanghai Institute of International Intellectual Property, the government should set up a communication channel for patent information, so that a large number of silent patents in universities and research institutes can "live" and realize their market value. Shan Xiaoguang pointed out that in 2016, the total number of invalid patents in colleges and universities in China was nearly 68,000, and a large number of patents were not transformed, even after they were granted rights, which was a serious waste of the value of scientific research results. Many researchers are limited by the policy orientation in the past, and submit patent applications only for job title evaluation and award declaration, etc., and their achievements are of low value and lack the value of transformation and application. In his view, the government should strengthen policy guidance, pave the way for bridging the gap between researchers and the market, and patent the essence of market economy and promote more and better achievements to realize value through transformation.

　　In recent years, the Shanghai Intellectual Property Office has frequently been a "matchmaker", bridging the gap between enterprises, institutions and patent service agencies, and deeply exploring the patent value. Shanghai Intellectual Property Office specially arranges funds to support enterprises to carry out patent navigation and patent evaluation projects. In the process of project implementation, the enterprise makes clear the direction of technology development in the industry through in-depth patent retrieval analysis, improves R&D and patent mining, actively develops patent layout, avoids the risk of patent infringement, supports and trains enterprises to carry out high-quality and high-value patent portfolio layout, and enhances patent competitiveness. As a frontline worker of patent service, Zhang Jingjie, general manager of Shanghai Xinhao Intellectual Property Agency Co., Ltd. (hereinafter referred to as Xinhao), has a deep understanding of the value of this service. She told reporters that adhering to the purpose of laying out high-value patent portfolio for enterprises, the company always attaches great importance to the writing quality of each patent application document, and starts from the source to ensure the protection and quality of each patent application, so that the patent portfolio of enterprises can truly reflect "high value" in actual intellectual property rights. On this basis, the company has made perfect patent analysis and patent strategy for enterprises for many years, laid out core patents with high market value and low substitutability, and attached importance to the layout of peripheral patents. In 2009, Xinyong made a 140-page boiler technology patent analysis for an enterprise in Shanghai in eight months, from technical details to R&D process, forming a comprehensive patent layout analysis, showing enterprises the tangible market prospects of related patent technologies.Enterprises can avoid intellectual property risks at home and abroad through patent layout in related fields, and at the same time produce a large number of high-quality patent applications. In 2016, the patent application rate of Xinhao Agency reached 63.43, ranking second in Shanghai. "Service organizations must generate value to society and cannot fall into low-level homogenization competition." Zhang Jingjie said that only by helping clients realize the value of patents, allowing enterprises and institutions to see the value of patents, and jointly enhancing the importance of high-value patents, can a virtuous circle in the field of patent services be formed.

　　Shanghai Rongzhi Intellectual Property Agency Co., Ltd. (hereinafter referred to as Rongzhi) is a model to help enterprises "gold rush" through high-value services. Under the organization of intellectual property organizations at all levels in Shanghai, Rong Zhi undertook the roadshow of intellectual property rights in Pudong New Area, Shanghai, and combined with specific projects, vividly demonstrated the value of high-value patent portfolio for participating enterprises and institutions, and realized the precise docking of patentees, technology demanders and investment and financing institutions. "In our view, high-value patents give R&D personnel new technical enlightenment in technology research and development, further improve the technical value of innovative achievements, and form high-quality, high-level patents or patent portfolios with great economic benefits and market strategic significance. In it, service organizations must do’ big waves to wash sand, wash away gold, improve gold, and build gold for treasure’. " Yu Xiaojing, general manager of Rongzhi, vividly compared the cultivation of high-value patents to the creation of jewelry: searching, excavating and improving the existing technical solutions of enterprises and institutions to form a higher-value solution, just like finding pearls in a clam; Through the improved scheme, the R&D personnel will be inspired to develop a better scheme, just like polishing the luster of pearls; Through high-quality document writing and perfect layout, the patent achievements will be transferred to the downstream to maximize the value, just like inlaying pearls into jewelry. From a penniless clam to priceless jewelry, it is the significance of cultivating high-value patents. Yu Xiaojing introduced that in the process of screening and layout practice of high-value patents, Rong Zhi gradually explored a set of innovations fromThe "seven-step patent precise operation" model of "retrieval-analysis-audit-layout-transfer/licensing-re-layout-linking industries" integrates the upstream and downstream technologies of the industrial chain, and the upstream demand drives the downstream industrialization, and the downstream demand promotes the upstream secondary research and development, forming a benign interactive circulation mechanism, thus realizing the precise operation of innovation transfer and transformation, and realizing the docking of patents and investment and financing industries.

　　With the support of Shanghai Intellectual Property Office, more and more patents realize their financial value through pledge or insurance. As an important intangible asset, high-value patents are increasingly favored by financial institutions. This year, Shanghai Intellectual Property Office has actively promoted patent pledge financing and insurance, and provided policy support for patent pledge financing in all districts and counties. Pudong New Area, Minhang District, Xuhui District, Fengxian District, Yangpu District, Huangpu District and Jing ‘an District have successively launched patent pledge financing and patent insurance pilot projects. From 2014 to 2016, Shanghai realized patent pledge financing of more than 2.7 billion yuan and pledged more than 500 patents; A total of more than 1,200 patents were insured, with a premium of 1.75 million yuan. Patents are intangible, but the patent value is not illusory, but heavy real money. The higher the value, the higher the return.

　　"We plan to develop a set of high-value patent evaluation system, screen and evaluate effective invention patents through a scientific evaluation index system, and implement stronger policy support for high-value patents to guide enterprises and institutions to pay attention to patent quality and the cultivation and layout of high-value patents. Through several years of hard work, the proportion of high-quality and high-value patents has been greatly increased. " Lv Guoqiang said that the improvement of patent quality and the cultivation of high-value patents are a systematic project and a long-term task in the process of building Shanghai into an Asia-Pacific intellectual property center city. In the next step, Shanghai will further increase investment in R&D, strengthen cooperation and collaborative innovation in Industry-University-Research, enhance the innovation ability of enterprises and institutions, and provide technical support for the cultivation of high-value patents; Further strengthen the professional training of patent agents, improve the quality of patent agents, and provide legal protection for the cultivation of high-value patents; Further strengthen patent operation, promote the implementation of patent transformation, transfer license, investment in shares, pledge insurance, etc., realize patent value and provide market protection for the cultivation of high-value patents; Further improve the patent support policy, increase the support for high-value patents, clarify the policy orientation, and provide policy guarantee for the cultivation of high-value patents. Innovative Shanghai, the future can be expected. (Intellectual Property News reporter Wang Yu Sun Di correspondent Nie Li)

　　At present, the epidemic situation in China is sporadic, frequent and local. The epidemic situation in the surrounding cities is severe and complicated, which coincides with the peak of return after the National Day, frequent personnel turnover, and the situation of epidemic prevention and control is not optimistic. The general public are requested to consciously abide by the relevant regulations on epidemic prevention and control, firmly establish the consciousness that "everyone is the first responsible person for their own health", wear masks scientifically, wash their hands frequently, ventilate frequently, and keep a social distance. When entering public places, we should consciously abide by various epidemic prevention and control measures such as temperature measurement, wearing masks, scanning place codes, and checking travel cards, and actively participate in nucleic acid testing organized by the village (community) and unit.

　　According to the relevant requirements of epidemic prevention and control:

　　2. Advocating the "three-day, three-inspection" of nucleic acids for people coming (returning) from other cities (except the above-mentioned areas).

　　Three inspections in three days: complete three nucleic acid tests within three days (with an interval of 24 hours), and do a good job of self-health monitoring. Do not gather, visit houses or go to crowded places within seven days, and strictly do personal protection when going out.

　　3. Promote "landing inspection"

　　Passengers are required to take the plane, high-speed rail, train, inter-provincial long-distance passenger bus, inter-provincial passenger ship and other means of transportation with negative proof of nucleic acid test within 48 hours.

　　Promote "landing inspection". In accordance with the principle of "taking and leaving voluntarily and free of charge, without restricting the flow", the inter-provincial migrants will take nucleic acid samples as soon as they arrive at their destinations. According to the requirements, complete the nucleic acid test in time, and incorporate the nucleic acid test results into the health code, so as to facilitate the masses to inquire about the test results.

　　4. Please pay close attention to the development of the epidemic situation, and avoid going to medium and high-risk areas and epidemic-related areas if it is not necessary.

　　Did not complete the whole vaccination of Covid-19 vaccine, to take the initiative to the designated inoculation point vaccination of COVID-19 vaccine. If you have symptoms such as fever, dry cough, fatigue, sore throat, decreased sense of smell (smell), nasal congestion, runny nose, conjunctivitis, myalgia and diarrhea, do a good job of personal protection, avoid taking public transport, and go to the fever clinic of the nearest medical institution in time.
