Description

one

The invention relates to electrical time instruments. The device is intended to periodically send pulses from an electric watch station to a primary watch to the secondary clock of the secondary clock.

Pulse-generating devices are known that contain contactless transistor elements controlled by a primary clock, thyristors and diodes forming two parallel circuits connected to a power source.

These devices also contain contact devices that drastically reduce reliability.

The proposed device for contactless generation of pulses is characterized in that, in order to increase reliability, each of the parallel circuits is made in the form of a series of connected thyristors, diodes and output electrodes of the transistor.

The collector of the transistor of the connection circuit through the current limiting resistor with the control electrode of the second circuit thyristor, the collector of the second transistor through the other current limiting resistor with the resistance of the thyristor of the first circuit, and the load circuit of the secondary clock is connected between the thyristor anodes.

FIG. 1 shows the scheme of using the device when working with electronic watches; pas figs. 2 - the same scheme when working with the primary electric clock of the EFC.

The device contains two transistors 1 and 2, two thyristors 3 and 4, and two different transducers 5 and 6, successively connected to the source of the iithia. The collector 1 collector through a limiting resistor 7 is connected to the control unit 1, the thyristor electrode 4 by it, and the collector of the trapsistor 2 through a limited circuit,

a resistor 8 with a thyristor electrode 3 is controlled. The bases of traisistor 1 and 2 are the device inputs and the load is connected to the anodes of thyristors 3 and 4. An electronic clock connected to the device using two matching and trigger circuits with a counting input is occurring negative signals with a duration of 1-2 seconds alternately at the bases of transistors 1 and 2. When a negative signal is inserted into the base of transistor 1, the latter opens, and the positive potential of the power supply through diode 5 is applied to the line 9 of the output line and Odio through the limiting resistor 7 - to the control

thyristor electrode 4, which opens and connects the minus of the iTitany source to line 10 in the running line.

Thus, the source of power is connected. to the load line. At the end of the pulse, transistor 1 and thyristor 4 are closed3

are. The load line is de-energized. After a minute, when the impulse from the electronic clock arrives at the other input of the device, transistor 2 and thyristor 3 are opened. The load line is again connected to the power source. However, in this case, a negative potential is applied to the bus 9, and a positive potential is applied to the bus 10.
