摘要： For aging a cathode-ray tube which has a cathode capable of emitting an electron beam, a first electrode for limiting the electron beam, a second electrode for accelerating electrons of the limited electron beam, a third electrode for focusing the accelerated electron beam and an anode, the cathode is energized so that an electron beam is emitted therefrom while D.C. rated voltages are applied to the first and second electrodes, respectively, and first and second voltages are applied to the third electrode and the anode, respectively, for a predetermined time. The first and second voltages are time-varying within first and second zones each of which is between a first level lower than the D.C. rated voltage on the second electrode and a second level higher than the highest one of the voltages on the third electrode with which an electric current flows in the second electrode with the electron beam emitted from the cathode. The first time-varying voltage is in phase with and lower than the second time-varying voltage. The first time-varying voltage is varying so as to be at a level between the first and second levels at least for a part of the above-mentioned predetermined time.

摘要： An electrical conductor device is connected between an anode voltage supply terminal on the funnel and an electron gun assembly in the neck in parallel with a conductive inner graphite film for electrical connection of the terminal and the assembly. The conductive inner graphite film has a high-resistance portion and a low-resistance portion, and the electrical conductor device has a smaller resistance than that of the high-resistance portion. Upon spot knocking, high voltage is selectively supplied to the electron gun assembly through the electrical conductor device and in operation, through the conductive inner graphite film.

摘要： In a method of fabricating a cathode-ray tube, an evacuated and sealed bulb provided with a phosphor screen and an electron gun including a cathode is subjected to a process of flashing a getter attached to the inner wall of the bulb. Thereafter, the bulb is subjected to a scanning process of causing the electron gun to emit an electron beam therefrom while deflecting the electron beam. The scanning process is followed by an aging process for the cathode of the electron gun.
