Abstract

PURPOSE:To facilitate actuation by connecting a diode in the forward direction from an electric power source to a base circuit. CONSTITUTION:In actuation, it is necessary to flow sufficient current to bases of transistors (TR) Q1 and Q2. To flow the sufficient current to bases of TRQ1 and Q2, a voltage applied to medium point A of the winding of the base circuit should be high. A voltage from electric power source V is applied to medium point A of the winding after being divided through diode D and resistances R1 and R2. Since backward resistance rd of diode D is extremely high, a high voltage can be obtained at medium point A. In normal operation, base current flows in the forward direction of diode D, so that the value of base resistance R2 adequate to flow the best current in the normal state can be selected.
