Geoffrey Gaut
Geoffrey Charles Gaut CBE (12 October 1909 – 18 August 1992) was a pioneering scientist in Britain's semiconductor industry. Early life Gaut was born in Penwortham, Lancashire. He was educated at the Royal Grammar School Worcester. He went to University College, Oxford, gaining a degree in Chemistry. He remained at Oxford and researched colloidal materials. During six years at Oxford, he was a member of the Oxford University Air Squadron, where he learned to master aerobatics. Career Plessey He joined Plessey in 1934, as the second graduate employee at the company, earning £6 a week, and rose to Chief Chemist. By the start of World War II, he was in charge of all the company's research and development. He volunteered to join the RAF, passed the necessary tests, and was commissioned as an officer. When Allen Clark, of Plessey, was told of this, he coerced the RAF to stop Gaut's commission. Gaut would later work with Allen's brother, John Clark. He would later qualify a ...

Semiconductor Industry
The semiconductor industry is the aggregate of companies engaged in the design and fabrication of semiconductors and semiconductor devices, such as transistors and integrated circuits. It formed around 1960, once the fabrication of semiconductor devices became a viable business. The industry's annual semiconductor sales revenue has since grown to over , as of 2018. The semiconductor industry is in turn the driving force behind the wider electronics industry, with annual power electronics sales of £135billion () as of 2011, annual consumer electronics sales expected to reach by 2020, tech industry sales expected to reach in 2019, and e-commerce with over in 2017. In 2019, 32.4% of the semiconductor market segment was for networks and communications devices. In 2021, the sales of semiconductors reached a record $555.9 billion, up 26.2 percent with sales in China reaching $192.5 billion, according to the Semiconductor Industry Association. A record 1.15 trillion semiconduct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar-absorbent Material
In materials science, radiation-absorbent material, usually known as RAM, is a material which has been specially designed and shaped to absorb incident RF radiation (also known as non-ionising radiation), as effectively as possible, from as many incident directions as possible. The more effective the RAM, the lower the resulting level of reflected RF radiation. Many measurements in electromagnetic compatibility (EMC) and antenna radiation patterns require that spurious signals arising from the test setup, including reflections, are negligible to avoid the risk of causing measurement errors and ambiguities. Introduction One of the most effective types of RAM comprises arrays of pyramid shaped pieces, each of which is constructed from a suitably lossy material. To work effectively, all internal surfaces of the anechoic chamber must be entirely covered with RAM. Sections of RAM may be temporarily removed to install equipment but they must be replaced before performing any tes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Commanders Of The Order Of The British Empire
Commander (commonly abbreviated as Cmdr.) is a common naval officer rank. Commander is also used as a rank or title in other formal organizations, including several police forces. In several countries this naval rank is termed frigate captain. Commander is also a generic term for an officer commanding any armed forces unit, for example "platoon commander", "brigade commander" and "squadron commander". In the police, terms such as "borough commander" and "incident commander" are used. Commander as a naval and air force rank Commander is a rank used in navies but is very rarely used as a rank in armies. The title, originally "master and commander", originated in the 18th century to describe naval officers who commanded ships of war too large to be commanded by a lieutenant but too small to warrant the assignment of a post-captain and (before about 1770) a sailing master; the commanding officer served as his own master. In practice, these were usually unrated sloops-of-war of no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alumni Of University College, Oxford
Alumni (singular: alumnus (masculine) or alumna (feminine)) are former students of a school, college, or university who have either attended or graduated in some fashion from the institution. The feminine plural alumnae is sometimes used for groups of women. The word is Latin and means "one who is being (or has been) nourished". The term is not synonymous with "graduate"; one can be an alumnus without graduating (Burt Reynolds, alumnus but not graduate of Florida State, is an example). The term is sometimes used to refer to a former employee or member of an organization, contributor, or inmate. Etymology The Latin noun ''alumnus'' means "foster son" or "pupil". It is derived from PIE ''*h₂el-'' (grow, nourish), and it is a variant of the Latin verb ''alere'' "to nourish".Merriam-Webster: alumnus .. Separate, but from the s ...

1992 Deaths
Year 199 ( CXCIX) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was sometimes known as year 952 ''Ab urbe condita''. The denomination 199 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

New Year Honours
The New Year Honours is a part of the British honours system, with New Year's Day, 1 January, being marked by naming new members of orders of chivalry and recipients of other official honours. A number of other Commonwealth realms also mark this day in this way. The awards are presented by or in the name of the reigning monarch, currently King Charles III or his vice-regal representative. British honours are published in supplements to the ''London Gazette''. Honours have been awarded at New Year since at least 1890, in which year a list of Queen Victoria's awards was published by the ''London Gazette'' on 2 January. There was no honours list at New Year 1902, as a list had been published on the new King's birthday the previous November, but in January 1903 a list was again published, though including only Indian orders until 1909 (while the other orders were announced on the King's birthday in November). There were also no honours issued in 1940, due to the outbreak of the Secon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Research Development Corporation
The National Research Development Corporation (NRDC) was a non-departmental government body established by the British Government to transfer technology from the public sector to the private sector. History The NRDC was established by Attlee's Labour government in 1948 to meet a perceived need at the time to exploit the many products that had been developed during World War II by the Defence Research Establishments. It was set up by the Board of Trade under the Development of Inventions Act 1948 and the first managing director was Lord Giffard. The NRDC was established in India in 1953 to help develop and promote technologies developed at various national R&D institutions. The first commercial size hovercraft, the SR.N1, was built under a contract let by the NRDC to Saunders-Roe in 1958. In 1981, the NRDC was combined with the National Enterprise Board ('NEB') to form the British Technology Group ('BTG'). Operations Typically the NRDC would patent the product for commerci ...

Gunn Diode
A Gunn diode, also known as a transferred electron device (TED), is a form of diode, a two-terminal semiconductor electronic component, with negative resistance, used in high-frequency electronics. It is based on the "Gunn effect" discovered in 1962 by physicist J. B. Gunn. Its largest use is in electronic oscillators to generate microwaves, in applications such as radar speed guns, microwave relay data link transmitters, and automatic door openers. Its internal construction is unlike other diodes in that it consists only of N-doped semiconductor material, whereas most diodes consist of both P and N-doped regions. It therefore conducts in both directions and cannot rectify alternating current like other diodes, which is why some sources do not use the term ''diode'' but prefer TED. In the Gunn diode, three regions exist: two of those are heavily N-doped on each terminal, with a thin layer of lightly n-doped material between. When a voltage is applied to the device, the electrical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
