However, the vast majority of hits from non-3M sources, including newspaper searches, Google, Google Books, and Google Scholar use the forms ''Thermofax,'' or ''thermofax,'' with lower-case f, no hyphen, and no trademark symbol. 〕) is 3M's trademarked name for a photocopying technology which was introduced in 1950.〔: "In the 1950s, 3M introduced the Thermo-Fax copying process..."〕〔: "The biggest seller was the Thermofax, introduced in 1950 by Minnesota Mining & Mfg. (3M). It was based on the thermographic process discovered by Carl S. Miller while he was studying for a Ph.D. in Physical Chemistry at the University of Minnesota in 1940."〕 It was a form of thermographic printing and an example of a dry silver process.〔The original 1950 process did not use silver, but a few years later the original process was supplanted by an improved silver-based version.〕 It was a significant advance as no chemicals were required, other than those contained in the copy paper itself. A thin sheet of heat sensitive copy paper was placed on the original document to be copied, and exposed to infrared energy. Wherever the image on the original paper contained carbon, the image absorbed the infrared energy when heated. The heated image then transferred the heat to the heat sensitive paper producing a blackened copy image of the original. ==Model 12== The first commercially available Thermofax machine was the Model 12. The 'layup' of the original and the copy paper was placed on a stationary glass platen and an infrared lamp and reflector assembly moved beneath the glass, radiating upwards. The layup was held in position by a lid with an inflatable rubber bladder that was latched down by the user. 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「Thermofax」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.
