    摘要： A method of manufacturing a cathode-ray tube comprises a process of forming a phosphor screen. The process comprises an application process, a shake-off process, and a drying process. In the application process, a glass panel is tilted with respect to a vertical axis and is rotated having a tilt axis as a central axis to spread a phosphor slurry over almost the entire area of an inner face of the glass panel. In the shake-off process, by rotating the glass panel, excess phosphor slurry is shaken off, and the excess phosphor slurry is recovered in phosphor-slurry recovery members provided at the four corners of the glass panel. In the drying process, the phosphor slurry is dried. In this method, the tilt angle and rotation speed of the glass panel at least in one process out of the application process, the shake-off process, and the drying process is changed at least in two stages. Thus, using large phosphor particles capable of obtaining a high luminance, a cathode-ray tube in which a phosphor screen, with uniform distribution of the phosphors and without a cross phenomenon, wall stain, and liquid spill onto the inner face, is formed on an inner face of a glass panel can be obtained.

    摘要： A first capacitor is arranged such that the electric potential at a first terminal is fixed. A first discharging circuit discharges the first capacitor at a timing that corresponds to a cyclic synchronization signal received from an external circuit. A first comparator compares the voltage at a second terminal of the first capacitor with a predetermined threshold voltage, and generate a judgment signal that corresponds to the comparison result. A charging circuit generates a charging current the current value of which is adjusted according to the level of the judgment signal at a timing that corresponds to the synchronization signal, and supplies the charging current thus generated to the first capacitor.
