Abstract

PURPOSE: To enable a simple and miniature constitution to prevent a large current from flowing through a gate pattern, by allowing the discharging current of a capacitor, connected in series between the gate pattern and switching circuit, to by-pass through a forward diode.
CONSTITUTION: Switching transistor 5 turns ON-OFF by pulse generator 3 and NAND circuit 4, and in its ON state, a fixed amount of a direct-current flows from direct-current source 6 to pattern 2 through capacitor 8 series-connected together with current control resistance between gate pattern 2 of a bubble memory and transistor 5, thereby performing gate operation. If transistor 5 would stay ON due to a fault of a switching circuit, the discharging current of capacitor 8 flows through diode 10 and resistance 9 of fixed resistance by by-passing pattern 2. Therefore the inflow of an overcurrent can be avoided by a simple and miniature constitution using no pulse transformer, preventing the pattern from burning.
