…In 1793, Amaga invented the double free piston Amaga pressure gauge, which measured high pressures up to 300 MPa. Meanwhile, in 1797, Nicolas Jacques Conté (1755-1805) was the first to come up with the idea of a barometer using a thin diaphragm, and in 1844, Lucian Vidie (1805-66) created a vacuum box with a corrugated diaphragm attached, and invented a barometer that measured pressure using its elastic deformation. In contrast to the mercury barometer, Vidie named this the aneroid barometer, from the Greek word anēros, which means "not liquid." … *Some of the terminology that mentions "Vidie, L." is listed below.

…93年,アマガは複自由ピストン型のアマガ圧力計をくふうし,300MPaに至る高圧力の測定を行った。一方,1797年コンテNicolas Jacques Conté(1755‐1805)が薄いダイヤフラムを用いた気圧計を初めて考え,1844年ビディLucian Vidie(1805‐66)は波状形のダイヤフラムを張りつけた真空箱をつくり,その弾性変形を利用して圧力を測る気圧計を考案した。水銀気圧計に対して,〈液体でない〉の意味のギリシア語anērosから,ビディはこれをアネロイド型気圧計aneroid barometerと名付けた。… ※「Vidie,L.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
