Abstract: 1,256,752. Transistor bi-stable circuits. OMRON TATEISI ELECTRONICS CO. 28 May, 1969 [8 June, 1968 (2)], No. 26962/69. Heading H3T. The first stage, such as F.E.T.'s 102, 103, of a flip-flop is set by the inputs 4 or 7 fed through diodes 3, 5 during a first clock pulse # 1 , and the second stage 105, 106 is set in consequence during a second clock pulse # 2 , the output 8 being fed back to the input 2, such as by a diode 13. The feedback may be through a resistor (13<SP>1</SP>, Fig. 3, not shown). If S i  is negative (1), diode 3 passes the negative level to a F.E.T. 101 which opens on the next clock pulse # 1  to apply the negative signal to the gate of F.E.T. 102. The drain of the latter goes positive (O) developing a potential across the impedance-connected F.E.T. 103 connected to the negative supply. On the next clock pulse of a second train # 2 , a F.E.T. 104 opens and turns off the F.E.T. 105 whose drain is connected to the output 8, 9 and goes negative. This negative signal is fed back to point 2 to maintain the state of the flip-flop, even after the input S i  has changed. The state of the flip-flop can only be changed by a reset input R i ; when this goes negative (1) an inverter 6 applies a positive signal R i  through diode 5 to input point 2 and changes the output 8 via diode 13, and the flip-flop changes over on receipt of the next clock pulses # 1 , # 2 .
