翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Electron Technologies, Inc. ： ウィキペディア英語版 Electron Technologies, Inc. Electron Technologies, Inc. (ETI) (formerly Electron Dynamics Division (EDD), a division of Hughes Aircraft Company) is a technology company specializing in the manufacture of microwave devices for ground-based, airborne and satellite communications and radar. ETI began operations at their Torrance, California, facility in 1967. They are known for their traveling-wave tubes (TWTs), traveling-wave tube amplifiers (TWTAs) and electronic power conditioners (EPCs) as well as xenon ion propulsion systems (XIPS).〔http://www.l-3com.com/divisions/overview.aspx?id=30 〕 Since its inception, ETI has produced tens of thousands of TWTs.〔http://www.l-3com.com/products-services/productservice.aspx?id=608&type=d 〕 They are the only U.S. supplier of space-qualified TWTs and TWTAs.〔http://articles.janes.com/articles/Janes-Space-Systems-and-Industry/Hughes-Electron-Dynamics-Division-United-States.html 〕 ==History== In the early 1950s, Hughes secured a military contract for the XF-108 Rapier interceptor's AN/ASG-18 fire control system and radar. At the end of the Korean War, the F-108 program was canceled, but Howard Hughes chose to keep the program going on company money. By 1959 Hughes Microwave Tube Division was operating in Culver City, California. The Microwave Tube Division was developing TWTs suitable for airborne radar and eventually won the contract for the F-14 radar system. By the time the F-14 program went into production, the tube division had outgrown the Culver City facility. Hughes moved the operation to Torrance, California, and it became Electron Dynamics Division (EDD). General Motors purchased Hughes Aircraft Company in 1985 and renamed the Torrance operations Electron Dynamics, a subsidiary of Hughes Electronics, maintaining the initials EDD. The Boeing Company purchased GM's satellite operation in 2000, acquiring EDD in the process, and renamed it Boeing Satellite Systems, Electron Dynamic Devices, again maintaining the initials EDD. Boeing sold EDD to L3 Communications, Inc. in 2005. L3 communications already owned another company with the initials EDD, thereby prompting a name change to L3 communications, Electron Technologies, Inc. or ETI for short. Boeing sold the property in Torrance to RREEF America REIT III Corporation (RREEF) in October 2006. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Electron Technologies, Inc.」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
