Abstract
PURPOSE:To apply the title horizontal deflection oscillating circuit of a direct driving system to a multi-scanning system, by controlling the pulse width and phase of a horizontal oscillating pulse with the output voltage of an F/V con verter. CONSTITUTION:For example, a horizontal synchronizing signal from a personal computer is given to a monostable circuit IC1, and the IC1 outputs the horizontal oscillating pulse in synchronization with the horizontal synchronizing signal. On the other hand, and F/V converter IC2 outputs the voltage corresponding to the frequencies of the horizontal synchronizing signal given to a sixth termi nal 11 from a first terminal 12, and gives the base of respective control transistors(TR) 1 and 2. Thus, the collector resistances of the TR 1 and 2 are changed, change synthetic resistances RX1 and RX2 to determine the hourly timing of the leading edge and trailing edge of the output pulse of the circuit IC1, and control the pulse width and phase of the horizontal deflection oscillating circuit. Consequently, the horizontal deflection oscillating circuit of the direct driving system can be applied to the multi-scanning system.
