Abstract
PURPOSE: To obtain a high vacuum degree while shortening an exhausting time considerably by giving ultrasonic wave to a bulb to promote the gas emission from the inside wall and the electrode when vacuum exhausting is performed under the state where the electrode is stored in an electronic tube.
CONSTITUTION: Oil diffusion vacuum pump 7 and oil rotation vacuum pump 8 are operated to perform vacuum exhausting in magnetron 6, and ultarsonic wave oscillator 15 is caused to oscillate ultrasonic wave. Next, this ultrasonic wave energy is applied to ultrasonic wave conductor 15a which contacts witg magnetron 6, and the heating current is flown to auxiliary heater 19 which is wounded around the outside of conductor 15a, thereby emitting gas absored on the electrode surface of magnetron 6. After that, when the vacuum degree in magnetron 6 becomes proper, electricity is supplied to electrode terminal 6b to heat the filament electrode, and oxide is activated to continue exhausting. After that, conductor 15a is removed to apply the high voltage from power source 18 to electrode terminal 6b, and an electron impulse is given to the anode inside wall to emit gas, thereby enhancing the vacuum degree further.
