The invention relates to a pulse technique, a computer and an automation, in particular, can be used as a pulse generator, memory. cell trigger, display element in optical computing machines

The purpose of the invention is to enhance the functionality by providing the JQ device with control of optical signals and the formation of both electrical and optical outputs, both direct and inverse.

FIG. 1 shows a basic optoelectric circuit of the device; in fig. 2 - volt-ampere characteristic and corresponding load direct for 1 -diode of the main bipolar element on the basis of which this device is built.

The common bus and the power bus are connected through parallel-connected voltage dividers, formed in pairs by a load resistor 1 and D 25 by a diode 2, photodetectors 3 and 4, electro-optical gates 5 and 6, 7 and 8. The average points of these dividers are connected by the output bus and. connected through a current-limiting resistor 9 with a galvanic. input 10 and directly with the electrical output 11 of the device. The device also contains a constant light emitter 12, made, for example, on an LED. In addition, the device has installation and resetting inputs 13 (R) and 14 (S) electrically developed from diode 2 and electrical output 11 due to the corresponding connection 13 (14)

waters of the electro-optical shutter 7 with the light input of the photodetector 4 (3). The input aperture of the electro-optical shutter 7 (8) is made in the virtual shutters 7 and 8 and the photodetectors 3 and 4. Let the electro-optical shutter 7 be closed at the initial time, and the shutter 8 open. The light passes through the light flux from the light detector to the photodetector 4, its diode 17 (18) and the corresponding bridge increases, the total loading (resetting) back-to-right moves to the upper optical input 19 (20) of the device. position 28 relative to the IVC of the L-diode Stream of a constant light output, the device switches to the gate 12 is directed through the optical fibers 55 to the logical 1.

operation of the device, the load resistor 1 is chosen such that, taking into account the voltage of the power source, the voltage characteristic of the load characteristic of the voltage source 23 intersects the current-voltage characteristic of the diode 24 at point 25 in the area with the negative. teltelny differential resistance; at the same time, the load characteristic 23 intersects the VAC of the L-diode at two more points, which are logical About 26 devices, and logical 1

In the process, the input binary

Signals go either to the galvanic input 10, or to the electrical R and S inputs 13,14, or directly to the optical R and S inputs 19 and 20. In relation to the galvanic input 10, the device operates as a storage cell. When the voltage drops across the galvanic - input 10 below zero, electrical output 11 appears logic O,

with increasing power supply voltage appears logical 1. With

at the galvanic input 10, between the indicated levels at the electrical output 11, the logical signal is maintained due to the last previous input signal that went beyond the specified range

When logic 1 is applied either to the electrical R (S) input 13 (14) or to the optical (R) (8) -input 19 (20), the logical O (1) is set at the electrical output 11. When this triggers electro-optical valves 5 (6), which ensures the formation, respectively. zero (single) light signal on the forward

act on photodetector 3, the et-o conductivity increases, the load current moves relative to the IVC-diode down, the device goes into a logical O state. Next, the switching process is repeated. Accordingly, the signal of the logic state at the electrical output 11 changes the signal at the forward optical output 21, and at the inverse optical signal the signal changes in antiphase.

Due to the presence of the installation and re-installation of optical inputs and direct and inverse optical outputs, this device can be used 5 as a typical element of optical computing machines. When executing the output apertures of electro optical shutters on the optical outputs in the form of symbols or symbol segments, it is possible to use this device; as an element of the light indication.
