絶対真空計の英語

安価で正圧に対しても耐久性のある相対圧真空計を用いて金型内キャビティの圧力を測定しながら、実質的には、絶対圧真空計を用いたのと同様に正確な真空圧値を表示し、それに基づいて真空ポンプを制御し、キャビティ内の真空度を設定値通りの値まで真空度を高める。例文帳に追加

To increase vacuum in a cavity to a set value using a relative pressure vacuum meter to measure pressure in the cavity and controlling a vacuum pump based on the accurate value of vacuum obtained by the relative pressure vacuum meter, the relative pressure vacuum meter which is inexpensive, durable to positive pressure and indicates such an accurate value of vacuum as the value obtained by using absolute pressure vacuum meter. - 特許庁

予めダイカストマシン周辺の大気圧を測定し、その結果を金型キャビティ内への溶湯注入時の真空度測定装置にフィードバックし、大気圧分をオフセットにして前記相対圧真空計で金型キャビティ内の絶対圧真空度を測定しながら金型キャビティ内を減圧する。例文帳に追加

The atmospheric pressure surrounding a die casting machine is measured beforehand and the feedback of this result is fed back to a vacuum measuring instrument used when the molten metal is poured into the cavity in the die, and while measuring the absolute pressure vacuum in the cavity in the die by the relative pressure vacuum meter by offsetting the atmospheric pressure, the pressure in the inner part of the cavity in the die is reduced. - 特許庁

そのサンプルに対する干渉波の位相変化量と真空に対する干渉波の位相変化量とに基づいて各測定区間について絶対屈折率を計算する。例文帳に追加

An absolute refractive index is calculated on each measurement section on the basis of the variation of phase of interference wave to the sample and the variation of phase of interference wave to vacuum. - 特許庁
