摘要：The present invention includes a Zener diodes (D1,D2) connected between ahelix electrode and an anode electrode, transistors (Q11,Q12) that close or open a circuitbetween a cathode and an anode of the Zener diodes, photocouplers (IC1,IC2) for turning
ON/OFF the transistor through phototransistors (D3,D4), a first switch (SW) for supplyingor cutting off a DC voltage for the photodiode of the photocoupler, a capacitor (C1) towhich the DC voltage that is to be supplied to the photodiode is applied and a controlunit that turns ON the first switch beforehand to apply a DC voltage to the photocouplerand the capacitor and that turns OFF the first switch simultaneously with an application ofa helix voltage.
