翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Unitron ： ウィキペディア英語版 Unitron Unitron is currently a US-based company and distributor of optical instruments including stereo microscopes and accessories, binoculars, and classic brass telescopes. Unitron was originally founded in 1951 by Lawrence A. Fine as the United Trading Company and located in Boston, MA.〔Sky and Telescope Magazine; October 1951〕 He registered the UNITRON trademark in the United States for first use in commerce in February, 1952.〔US Patent and Trademark Office: March 22, 1954〕 The company started out importing smaller (1.6" to 4" refractors) that were manufactured by Nihon Seiko of Japan.〔Classic Telescopes, Neil English, pg 152〕 By 1961 Unitron expanded the product line to include 5" and 6" models that were suited for observatory use. A very small number of the 5" and 6" models were produced. Several of the 6" Model 620's remain operational at observatories to include: Rafes Urban Astronomy Center, Denton, Texas; Castleton State College, Castleton, Vermont, and the University of Connecticut, Storrs, Connecticut.〔Unitronhistory.com Website, http://www.unitronhistory.com/locations/〕 Fine sold the company in 1975 to Ehrenreich Photo Optical Industries and it was relocated from Boston to New York.〔UnitronUSA Website: http://www.unitronusa.com/about〕 Unfortunately both he and his spouse Ellen were killed in a private airplane crash in Canada on 3 August 1978 and much of the early history of the company was lost. The Unitron as well as Polarex and lesser-known Weltblick telescopes were all manufactured by Nihon Seiko until that trading company went out of business in 1992. The telescopes (which included 1.6" to 9" refractors) were noted for their high quality specifications and metal and wood construction.〔Ting Ed (2007-12-30). (Telescope Reviews ) ''Scope Reviews'', retrieved February 13, 2009〕 (see UnitronHistory.com website) The company is currently located in Commack, New York and manufactures primarily microscopes and accessories for industrial use. The telescope product line is limited to several classic brass telescopes suited primarily for awards and presentations.〔UnitronUSA Website: http://www.unitronusa.com/about〕 ==References== 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「Unitron」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.
