Description

A switch made on a push-pull ferrite-transistor shift register, with a pulse-shift generator, is used to round the (ring) interrogation of memory cells. The proposed switch differs from the known ones in that it allows to shorten the time of interviewing correspondents by rapidly running them around if there is no information. if in the next cell the information is recorded, then the distributor stops for the time this information is processed by the executive body. This is achieved by including a multivibrator based on semiconductor triodes in the shift pulse generator, in the emitter circuits of the triodes which include control triodes, the bases of which are connected to the collectors of two triggers of the output device. The input of one of these triggers is connected to the output windings of odd memory cells, the input of the other to the windings of even cells, and the outputs of the triggers through the OR circuit are connected to the input of the actuator whose output is connected to other inputs of the triggers.

FIG. 1 is a block diagram of a switch; in fig. 2 is a schematic diagram of a shift pulse generator.

The switch consists of the following elements: pulse formers 1 that serve to receive pulses that are synchronous with the frequency of the shift pulse generator;

ferrite-transistor cells 2 of the memory, in which information is written from the pulse shapers upon the appearance of input signals;

an annular distributor 3, which serves to alternately poll the memory cells;

No. 146098-2 generator 4 shift pulses, which is a multivibrator on semiconductor triodes;

Scheme 5 OR for the number of inputs defined by the number of even and odd memory cells;

output device 6, containing the triggers 7 and 5 with the scheme 9 "OR.

The switch works as follows. If there is no information in the memory cells 2 in the ring distributor 3, the unit recorded during the initial installation circulates. When an input signal appears on any of the drivers / unit, the unit is recorded in the corresponding cell 2 of the memory.

I. pulse from the distributor 3 reads the signal from the first memory cell in which the unit is written. This signal puts state / flip-flop 7, or flip-flop 8, depending on whether the simplified cell is even or odd.

Triggers 7 and 5 through the triodes 10 and // (Fig. 2) control the multivibrator by breaking the emitter circuit of its triodes 12 and 13, stopping it at the beat corresponding to the simplified cell. Triggers 7 and 5 simultaneously with the shutdown. The multivibrator outputs through the circuit 9 “OR the signal to start the executive body. After testing this signal, the executive body sends a signal that returns the triggers 7 and § to the initial state. At the same time, the control triode 10 (11) opens, the multivibrator is started and the interrogation of the memory cells is resumed from the clock cycle corresponding to the cell following the last simplified one.

In conclusion, the IEM of the Academy of Sciences of the USSR notes the advantage of the proposed switch over the known performance and reliability.

Subject invention

A switch on a push-pull m ferrite-transistor shift register with a generator of shifting impulses, characterized in that, in order to "stop for the duration of information processing, a multivibrator is included in the generator of shifting pulses, the triodes incorporate triodes into the emitter circuit the divider is connected to the outputs of two triggers, the input of one of them is connected to the output windings of the odd memory cells, and the other one is even, and the outputs of the flip-flops are OR connected to the input of the actuator, the output of which, in turn, is connected to the other inputs of the triggers.
