とも電圧が印加されないため、動作せず、電極８に高圧
がかからなくなる。As a result, the voltage between both ends a and b of the thyristor 3 becomes approximately 0■, and the photosensitive solid state oscillation element 5 and the light emitting diode 6
Since no voltage is applied to both, they do not operate and no high voltage is applied to the electrodes 8.
一方、ガスが立消えると、発振素子４には、光が照射さ

こり、放電によりガスが点火する。On the other hand, when the gas disappears, the oscillation element 4 is no longer irradiated with light, the thyristor 3 is turned off, and the light emitting diode 6 irradiates the oscillation cord 5 again, causing oscillation, and the gas is ignited by discharge. do.
ガスコックが閉栓されると、スイッチ２も同じオフとな
る。When the gas cock is closed, switch 2 is also turned off.
