Astronaut Hu Guohua： the first person in the new China patent.

Cctv news On March 29, 1984, a young man came to the office of the State Patent Office, which was still painting and laying bricks. He held the card "Patent applicants line up here, the first aerospace institute 207" in his hand, and held it up and hung it on the door frame. When the scattered people around him saw that the young man was the vanguard, they consciously began to line up. This young man is Hu Guohua.
It turned out that in 1984, China’s first patent law was officially promulgated and implemented in April. After learning this news, Hu Guohua, who was working in No.207 Institute of the Second Hospital of the Ministry of Aeronautics and Astronautics at that time, came up with the idea of fighting for the first invention patent and letting the national No.1 patent "blossom" in space. In order to ensure that astronauts can obtain the first patent, Hu Guohua came to the National Patent Office to inquire in advance. He found the office that accepts patent applications. Although he hasn’t officially started to apply, there are already many people around him who are wandering around like him. Hu Guohua had a brainwave and wrote a card "Patent applicants line up here, ranking first in Aerospace Institute 207". People who didn’t know what to do originally were lined up by Hu Guohua.
In the afternoon, Hu Guohua brought bedding and waited outside the office for three days and nights. On April 1, 1984, he was finally the first to submit the patent application. In December 1985, Hu Guohua successfully obtained the certificate with the patent number of "85100001.0" issued by the State Patent Office, and became the "No.1 Patent" inventor of New China. The patent he applied for is called "Variable Optical Filtering Real-time False Color Display Method and Device". Simply put, it is to turn a black-and-white picture of the earth taken from a satellite into a color image according to certain characteristics, so as to see more information.
Do not forget your initiative mind is only because of the space dream.
In 1966, 23-year-old Hu Guohua graduated from the Physics Department of Fudan University and was assigned to work in Beijing Institute of Physics, China Academy of Sciences. In 1970, he took the original research topic and transferred to the 207 Research Institute of the Second Hospital of the Seventh Machinery Department (later the Space Department) to engage in optical research. Since then, the space dream has been deeply rooted in Hu Guohua’s heart and has become the driving force for him to persist in developing products for so many years.
His laser group is the earliest unit to carry out modern physical optics research in China. It started not too late, but because of the new principle, high requirements and low output of scientific research equipment, it needs to spend a lot of foreign exchange to import from abroad. Hu Guohua was very upset when he saw this situation, so he decided to design a set of cheap, universal and systematic modern optical experimental device.
The road to design is full of hardships. The difficulties he encountered were enormous: there was no assistant, no funds, no factory building, and even no laboratory where a newly-developed experimental instrument was placed. Hu Guohua’s difficulties attracted Deng Xiaoping’s attention. With the support of important responsible comrades of the Institute, the Institute, the Ministry and the Central Committee, Hu Guohua’s belief was strengthened, and he worked day and night to develop and tackle key problems.
Once he tried to design a "resettable device" with a reset error of less than one thousandth of a millimeter. He thought about walking and eating, but turned a blind eye to people. One night, he designed another device. Because he used his brain too much, his eyes suddenly turned black and he couldn’t see anything until noon the next day.
In 1980, Hu Guohua also developed the "Holography and Optical Information Processing Experimental System", which consists of 15 sets of more than 60 devices, including lasers, shock-proof platforms, optical and mechanical components. It can do dozens of modern optical experiments, such as holography, laser speckle, image spectrum analysis, spatial filtering and optical information processing, and is widely used. It can make blurred electron microscope images or satellite photos clear, and promote the early realization of optical computers with faster speed and larger capacity than electronic computers. The successful trial production of this experimental system has filled a gap in optical research equipment in China. At that time, only a few countries such as the United States could make and use it.
70-year-old retired to "plant the sun"
As an astronaut, Hu Guohua always has an "aerospace dream" in his heart. He dedicated his best years to the aerospace industry. After retirement, Hu Guohua still insisted on his own aerospace dream and never stopped after his seventies.
In recent years, based on years of research in the field of optics, and considering the future of industrial development, the leaders of 207 research institutes decided to participate in the project competition of developing a large-scale solar simulator in a research institute in Beijing, and formed a research team with optical experts to manufacture a solar simulator with a diameter of two meters. Hu Guohua, who was retired at that time, was one of them.
After studying the information about the manufacture of solar simulators at home and abroad, Hu Guohua began to challenge the research and manufacture of solar simulators according to the requirements of Institute 207. He worked tirelessly. In order to buy the parts for manufacturing the solar simulator, he personally drove around Beijing and found the relevant manufacturers to customize it himself. For a component, he has been to an optical production factory in Tongzhou District, Beijing for many times. Because of the special components he requires, even the technicians who process the components don’t know much about it. Therefore, he became a teacher again, explaining the principles and requirements of manufacturing optical components to technicians.
At that time, Hu Guohua was over seventy years old, and everyone in the team affectionately called him "the elder". Hu Guohua said: "I have never felt that I am a ‘ Elder ’ It’s never too old to learn. " He taught his experience and knowledge to young people without reservation, and at the same time learned from them their enterprising spirit.
Stick to the same as before, the space is boundless
Professional innovation, in life, Hu Guohua is using the knowledge to serve the public.
After retirement, Hu Guohua once created a space haunted house for an old Beijing street in the New Dong ‘an market in Beijing. Through the combination of space sound equipment and sound and photoelectricity, the horrible scene is reproduced. At that time, tourists lined up to experience the sci-fi effect of space sound; Hu Guohua also applied optical knowledge to anti-counterfeiting technology, made anti-counterfeiting trademarks for Xinjiang Tobacco Company, and made contributions to cracking down on counterfeit and shoddy products and raising national tax revenue.
Hu Guohua often uses it to help some poor countries. In April 2016, some scientists and technicians from Malaysia and Indonesia planned to build hydropower stations in some mountainous areas of East Malaysia to solve the lighting and living problems for local people. At this time, they found Hu Guohua, and Hu Guohua immediately planned for them and led them to visit Jinhua, Zhejiang. He brought China’s technology to Southeast Asia, which not only enabled the residents in those areas to use electricity, but also enabled China to transfer technology and gained economic benefits.
But doing all this, Hu Guohua didn’t make a penny. He spends his energy and wisdom to help others, which fully shows the feelings of an astronaut, that is, he is open-minded and generous, and he is willing to do whatever he can, regardless of gains and losses.
For half a century, Hu Guohua’s determination and belief in practicing his space dream need not be repeatedly emphasized. He has been telling people that he is an astronaut and practicing his space dream with practical actions.
