5 reverse transistor transistors, and a capacitor, the first plate of which is connected to the common bus, and the second to the emitter of the first direct transistor, and through co0 therefore the first and second resistors connected to the base of the first reverse transistor transistor whose base is connected to the collector of the first direct transistor, and the emitter is connected to a common bus, the base of the second reverse transistor transistor is connected to the input signal bus and Through the third resistor - with a common bus, the collector of the second reverse-conductor transformer is connected to the first output bus, and the emitter is connected to the common bus, the input signal bus is connected through the fourth resistor to the base of the first forward transistor, through the second transistor the fifth resistor is connected to the 11th first output signal, and through the sixth resistor it is connected to the busbar and the emitter of the same transistor, and the collector is connected to the combined terminals of the first and second resistors and bus second output. The drawing shows the scheme of the one-shot. The single-oscillator contains transistors 1 and 2 of direct conduction, transistors 3 and 4 of reverse conduction capacitor 5 and resistors 6-11, with the first plate of capacitor 5 connected to the common bus and the second to the emitter of transistor 1 and through series-connected resistors 6 and 7 is connected to the base of transistor 1 and the collector of transistor 3, the base of which is connected to the collector of transistor 1, and the emitter to the common bus. The base of transistor 4 is connected to the input signal bus 12 and through a resistor 9 to a common bus, the collector of transistor 4 is connected to the output signal bus 13, a. emitter with a common bus, bus 12 is connected via a resistor 8 to the base of the transistor base of transistor 2 is connected via resistor 10 to bus 13 and through resistor 11 to the power line 14 and emitter of transistor 2, the collector of which is connected to the combined terminals of resistors 6 and 7 and bus 15 output signal. The single-vibration device operates as follows. In the initial state, all the transistors are closed, the capacitor 5 is discharged at the bus 13 is high potential, and at the bus 15 is low. When a positive pulse is applied to bus 12, transistor 4 opens, the potential at output 13 drops to almost l and also transistor 10 opens through resistor 10

2. The potential at the output 15 increases to the voltage of the power source, the current through the resistors 7 and 8 keeps the transistor 4, and hence the transistor 2 in the open state. The capacitor 5 is charged through a resistor 6 from a high potential on the output 15. As the voltage on the capacitor 5 exceeds the voltage at the base of the transistor 1, which is determined by the voltage divider of resistors 7 and 8, the transistors 1 and 3 open and the input t in saturation. The open transistor 3 shunts the current passing through the resistor 8, the transistor 4 closes, the potential at output 13 increases to the supply voltage, the transistor 2 also closes and the potential at output 15 drops to almost zero, and the capacitor 5 discharges through open transistors 1 and 3, after which the transistors 3 and 1 are closed and the circuit returns to its original state. The invention allows two output signals to be generated at once, inverted relative to each other, and the Single Vibrator does not consume power in the absence of a pulse.
