Abstract

PURPOSE:To realize the formation of the titled device by an ordinary transistor circuit, by obtaining an output pulse having prescribed pulse width by a means which inverts output by a trigger pulse and sets a self-holding state, aud a means which cancels the self-holding state by a voltage boosting due to the charge of a capacitor when a charging voltage arrives at a prescribed level. CONSTITUTION:The titled device is constituted of a current driving type transistor circuit, and the collectors and the emitters of transistors Q1 and Q2 are connected, respectively, and the self-holding state is generated by inputting the trigger pulse to the base of the transistor Q1, and the following boosting of the charging potential of the capacitor cancels the above self-holding state, then, an output pulse can be obtained from the collectors of the transistors Q1 and Q2. In other words, the circuit is constituted so that a constant current can be supplied from a power source circuit to the transistors Q1-Q5 and the capacitor C1. In such a way, the titled device can be formed by the ordinary transistor circuit possible to be integrated.
