摘要： An apparatus for the high voltage treatment for a cathode ray tube including a neck having one end closed with a stem and housing an electron gun and stem pins for a focus electrode and other electrodes of the electron gun, establishes a high pressure gas atmosphere around the neck, and establishes a voltage which is sufficiently higher than the operating voltage of the cathode ray tube between the stem pins when the high pressure gas atmosphere. In order to prevent a creeping discharge due to the voltage applied to the stem pins, the temperature of the neck is maintained above the temperature of said high pressure gas atmosphere during the voltage application. In an alternative method, the dew point of the high pressure gas atmosphere is set at, at most, 25.degree. C.

摘要： A getter film is formed on an inner surface of a funnel portion of a cathode ray tube, and an inner conductor of the cathode ray tube is heated by a heating unit. According to this heating, the gas which is physically adsorbed by the inner conductor of the cathode ray tube other than the getter film is discharged and then chemically adsorbed again by the getter film, whereby a degree of vacuum in the cathode ray tube can be increased.
