Abstract

PURPOSE:To enhance working efficiency by providing a circuit unit forming the comparator of working space voltage and reference voltage at the time of pumping and a circuit unit forming the comparator similarly at the time of working, and making space control speed in response to comparision voltage at the time of pumping higher than that at the time of working. CONSTITUTION:Second circuit unit 23 operates at the time of working, and space 3 is controlled through bulb 10 and feeder 9 in accordance with the differential voltage between voltage Eo corresponding to reference voltage generator 11 and voltage e corresponding to working space 3. When a pumping signal is sent from oscillator 20 to electrodes 1, unit 23 stops its operation and first circuit unit 21 operates. A current in accordance with the differential voltage between Eo and e is similarly set with resistance R5 and supplied to bulb 10. By setting resistance R5 so that the response speed of space 3 at the time of operation of unit 21 is made higher than the response speed of unit 23, pumping time is minimized and working efficiency is enhanced.
