plastic instabilityとは 意味・読み方・使い方

To provide a combustion pressure sensor, capable of reducing a possibility of generating decline in the combustion pressure sealability, plug looseness or the like, based on instability of a seat surface shape caused by plastic working or a weld bead, and also of reducing the possibility of opening of a preload of a pressure detection element caused by deformation of a welded zone, or sensitivity deterioration of the pressure detection element caused by heat during welding.例文帳に追加

塑性加工や溶接ビードによる座面形状の不安定性に基づく燃焼圧シール性の低下やプラグゆるみ等の発生の虞を低減することができるとともに、溶接部の変形による圧力検出素子のプリロードの開放や溶接時の熱による圧力検出素子の感度劣化の虞を低減することのできる燃焼圧センサを提供する。 - 特許庁
