Abstract

PURPOSE:To improve characteristic in reduction of heating time, economization of its consuming energy and cost-down by performing the exhausting process of gas in the tube. CONSTITUTION:In the exhaust process of gas in a cathode-ray tube, degassing is performed out of the parts in the exhausting in a vacuum evacuation system composed of an oil rotary pump and an oil diffusion pump within normal temperatures or atmosphere under room temperature without heating the cathode-ray tube. In this case, for example, 10<-3>-10<-4> Torr is obtained for vacuity in the tube, the main content in the resiudal gases is found overwhelmingly much of H2O, which are then absorbed by Ba getter evaporating splashed membrance resulting in being 10<-5>-10<6> Torr of vacuity. Thus, is disopenses with any heating furnace for evacuating air, enables to sharply reduce the production cost and to save energy consumption.
