Inventory Of 60 Major Inventions Of New China (Eight)

5. magnetic bearing (magneticbearing, MB), also known as magnetic bearing.

Introduction: the theory of pulling and pushing magnetic circuit has been published for 25 years.

Professor Li Guokun, founder of Gansu Province, uses the latest research results of the theory "magnetic bearing".

It is a new type of high performance bearing with magnetic force acting to suspend the rotor in the air, so that there is no mechanical contact between the rotor and stator.

Compared with the traditional ball bearings, sliding bearings and oil film bearings, magnetic bearings do not have mechanical contact. The rotor can run to a high speed. It has the advantages of small mechanical wear, low energy consumption, low noise, long life, no lubrication and no oil pollution. It is especially suitable for high speed, vacuum, super clean and other special environments.

Impact: the results of the invention have successfully solved some problems in China's aerospace engineering. Once the patent is applied, it will bring huge economic and social benefits.

6. key supporting technologies for video coding standard

Brief introduction of invention: key supporting technology of AVS video coding standard completed by Huazhong University of Science and Technology.

Impact: in 2006, the key supporting technology of AVS (audio video code standard) video coding standard is currently widely used in network TV (IPTV), digital satellite live broadcast, high-density compact disc and video surveillance, and mobile video communications.

It has been officially adopted as the national standard.

The AVS video coding standard supports multi bit rate, resolution and quality video compression. It adopts a series of technologies to achieve high efficiency video coding. It solves the problems of high royalty, complex licensing policy, such as MPEG-2, MPEG-4 and AVC. It is an open national and international standard and is easy to promote.

7. Xu Daohua: "water doctor oxygen activating water heater"

Brief introduction of the invention: the design makes the deep activation processing system for ordinary tap water skillfully designed into a seemingly ordinary tap. Ordinary families only need to connect the "water doctor and water heater" to improve the quality of drinking water at home.

Impact: new water doctor oxygen series products can quickly process tap water, and easily achieve separate water supply within users.

The 8. generation CXS: Mobile casing gas recovery device

Brief introduction of the invention: in 2003, after 3 months' painstaking research, Dai Xusheng developed a mobile casing gas recovery device, which thoroughly solved the waste and air pollution caused by the exhaust of casing gas, and filled up the blank of domestic technology at one stroke. The annual profit of Shengli oil field was about 10000000 yuan.

Influence: "mobile casing gas recovery device", which thoroughly solves the waste and air pollution caused by casing gas discharge, fills in the blank of domestic technology at one stroke, and achieves an annual profit of about 10000000 yuan in Shengli Oilfield.

Over the years, Dai Xusheng has completed more than 80 achievements in technological innovation, of which 13 have won national patents and 1 national patents have been declared, with a cumulative effect of more than 100 million yuan.

9. dragon core

Introduction: dragon core (English: Loongson, formerly known as Godson) is a universal CPU developed by the Institute of computing technology of Chinese Academy of Sciences. It uses a simple instruction set, similar to the MIPS instruction set.

The speed of model 1 was 266MHz, which was first used in 2002, and Godson 2 was the highest speed of 1GHz.

Godson 3 has yet to be finished, and the target is multi-core design.

Impact: the Godson CPU, developed by the Institute of computing technology of the Chinese Academy of Sciences, is the first general computer CPU chip with independent intellectual property rights in China. Its successful development ended the history of China's independent development of CPU chips.
