摘要： A horizontal deflection circuit comprises a horizontal oscillator circuit (2), a drive transistor (4), a horizontal output transistor (51) driven by the output of the drive transistor, a timing circuit (7) for setting a timing delayed by about one fourth the horizontal scanning period from the terminating point of the flyback pulse generated at the collector of the horizontal output transistor, a phase difference detector circuit (9) for detecting the phase difference between the leading edge of the collector pulse of the horizontal drive transistor and the timing set by the timing circuit, and a pulse duration variable output circuit (3) triggered by the output of the horizontal oscillator circuit and with the output pulse duration thereof controlled by the output of the phase difference detector circuit. The horizontal drive transistor is driven by the output of the pulse duration variable output circuit, so that the leading edge of the collector pulse of the horizontal drive transistor is rendered to coincide with the timing set by the timing circuit.

摘要： A frontal light extraction type beam-indexing color picture tube arrangement comprises a phosphor screen which is formed on the inner surface of the tube panel (2) and includes an array of color phosphor stripes each of which has an appropriate afterglow time and an array of index phosphor stripes (12a; 18; 1 1 , 1 2 ) each of which has a short afterglow time and emits a light index signal representative of the scanning position of an electron beam in the forward direction of the tube panel. A photoelectric converter (7) for receiving the light index signal is provided in front of the tube panel.

摘要： An amplitude-adjusting circuit used for a contrast-adjusting circuit of resistor division type in which a video signal is applied across a pair of series-connected resistors (23,251) and an output is produced from the junction point of the two resistors. At least one of the resistors is used as a variable resistor. The amplitude-adjusting circuit comprises a current source for supplying a constant current steadily between the terminals of the variable resistor, a high-gain amplifier (29) for controlling the resistance value of the variable resistor, and a filter (31, 33) for separating the video signal component from the change of the value of the variable resistor represented by a voltage change, and introducing the resistance change to the high-gain differential amplifier.
