cylinder cut off testとは 意味・読み方・使い方

The electron microscope is provided in which an excitation current or an impressing voltage to an objective lens or an acceleration cylinder for accelerating electron beams of the scanning electron microscope is cut off when the measuring object test piece is separated from underneath of the objective lens, or is made weak excitation compared with before separation for excitation current, or cut off or made to be lower voltage compared with before the separation for impressing voltage.例文帳に追加

上記目的を達成するために、走査電子顕微鏡の対物レンズ、或いは電子ビームを加速するための加速円筒への励磁電流、或いは印加電圧を、測定対象試料を対物レンズ下から離間させたときに、励磁電流をオフ、或いは離間させる前に比べて弱励磁、又は印加電圧をオフ、或いは離間させる前に比べて低電圧とする電子顕微鏡を提案する。 - 特許庁
