れる。When the sliding contact 5G contacts the resistance pattern part 46 from the insulation pattern part 41 by operating the 1IJtiD operator 34 of the grip tube connection pipe part 28 of the hose 24, the switch is turned on, and the AC power supply 55 is connected to the rectifier circuit. The current, which is full-wave rectified by 65 and regulated by a Zeno diode 71, is charged in a capacitor by controlling the charging amount by a charging cycle variable resistor 75 such as a safety resistor 73, a variable resistor 38, and a semi-fixed resistor 52. It is charged to 77. When the voltage across this =1 capacitor 71 reaches the reference voltage set by the resistor 81.82, the PUT 78 turns on, and the charge in the capacitor 7 is discharged from the anode of the P tJ T 78 to the quadrupole. From the cathode of this PUT78 to the thyristor 84
