Abstract
PURPOSE:To block a vertical output pass with which the horizontal signal component of a positive feedback circuit is mixed and to make a separately excited vibrating action by connecting in series a switching diode with a positive feedback circuit. CONSTITUTION:When a vertical synchronizing signal is inputted, an electrode negative signal is turned to a straight polarity pulse by an inverter transistor 2, an oscillating transister 9a is triggered through a coupling capacitor 4. A sawtooth output prepared at an oscillating circuit is amplified in a drive circuit 10 and generates a vertical output pulse P in the output circuit of 11. This pulse is partial-pressed in resistances 7, 8 through the coupling capacitor, a stepped-down vertical output pulse voltage is generated to the resistance 7, however since a diode serially connected with a resistance 6 is of a reverse polarity, can not be triggered by a switching transistor 9a. Consequently, the action is of a direct driving system without a positive feedback pulse.
