critical hardnessとは 意味・読み方・使い方

To provide an optical information recording medium which has a hard coat layer of high hardness, is hardly splotched due to its low critical surface tension, has small warpage when used as a card and excellent bending resistance.例文帳に追加

ハードコート層の硬さが高く、臨界表面張力が小さく汚れが付きにくく、カードの反りが小さく、かつ曲げ耐性に優れた光情報記録媒体を提供する。 - 特許庁

By making hardness of the inner face higher than that of the outer face by forming a diffusion hardening layer on the inner face of the metal sheath, and by applying wire drawing by filling a MgB_2 superconductor, and as needed, improvement materials of the critical current density such as indium, copper, and tin into the sheath in the state, the superconducting wire rod is produced.例文帳に追加

金属シースの内面に拡散硬化層を形成して内面の硬さを外面の硬さよりも高くし、その状態でシース内にＭｇＢ_２超電導体、更に必要に応じてインジウム、銅、錫等の臨界密度向上物質を充填して伸線加工を施し、超電導線材を製造する。 - 特許庁
