摘要： It is an object to enable an optimum video display to be obtained by automatically adjusting a display size and a display position of a video image no matter what kind of video signal is supplied. A comparator detects a video display period of a video signal a and generates a detection signal b. A counter, latch circuits, comparing circuits, and the like form information of the start position or end position of the video display period of the video signal a and period information of the video signal a. An arithmetic operation control circuit generates control information of the display size, display position, and the like from those information by arithmetic operations by using a detection signal b and a horizontal sync signal h. A memory holds the control information. The control information is read out when a power source of the display is turned on at the next time.

摘要： A source-voltage controlling high voltage stabilizer for detecting the high voltage and controlling the source voltage, while providing a detector detecting the envelope of a horizontal deflection current, wherein the deflection current is stabilized as the voltage distribution of two scanning capacitors in a diode modulation type output stage and is so controlled that a coincidence is attained between the wave form of the output signal and that of the horizontal deflection current modulation signal. The source voltage supplied to the input side of the flyback transformer is controlled in such a manner that the high voltage obtained from the output side of the flyback transformer is maintained constant, and the circuit further has a variation detector for detecting the variation in the source voltage, wherein the detected variation component is applied to one of the junctions of the modulation coil.

摘要： A high-voltage stabilizing circuit for stabilizing high voltages such as those generated by the fly-back transformer of a television. The stabilizer includes a common-emitter type PNP transistor and an inverse current-absorbing capacitor with a small capacitance in order to provide a high-speed response. The collector of the transistor is connected with the primary coil of the fly-back transformer and the capacitor. The emitter of the transistor is connected with a power source. With this arrangement, even though parabolic wave voltages are generated at the capacitor due to the small capacitance, the PNP transistor hardly cuts off at all and can therefore supply adequate current to the fly-back transformer.
