normal gap lengthとは 意味・読み方・使い方

In D.C. type discharge lamps 20 and 30, both the electrodes are discharged and worn by applying a voltage having a polarity reverse to that in normal lighting for a predetermined period, so that the discharge gap length is adjusted to a predetermined length.例文帳に追加

また、直流形放電ランプ２０，３０においては、通常の点灯時とは逆極性の電圧を所定期間にわたり印加して両電極を放電磨耗させ、放電ギャップ長を所定の長さに調整する。 - 特許庁

In an A.C. type discharge lamp 10 with a pair of electrodes 13a and 13b oppositely disposed, both the electrodes 13a and 13b are discharged and worn by previously applying, between both the electrodes 13a and 13b, a voltage with its duty cycle varied with respect to an application voltage in normal lighting, so that the discharge gap length is adjusted to a predetermined length.例文帳に追加

一対の電極１３ａ，１３ｂが対向配置された交流形放電ランプ１０において、通常の点灯時の印加電圧に対してデューティーサイクルを変化させた電圧を両電極１３ａ，１３ｂ間に予め印加して両電極１３ａ，１３ｂを放電磨耗させ、放電ギャップ長を所定の長さに調整する。 - 特許庁
