SU428419A1 - INDICATOR DEVICE - Google Patents

Description

Previously, the device has been designed for radio engineering and can be used in a matrix and indicator devices with built-in memory.

Famous devices on gas: a series of panels contain, in logic, keys, diode-resistive elements, a driver, a clock voltage generator, and a control voltage driver. . In these automata systems, the reduction of false ignitions in the information field is achieved by using complex control circuits containing a large number of components, which leads to reliability.

The purpose of the present invention is to improve the reliability of the operation of the device; the way, the simplification of the scheme, which serves to eliminate spurious ignitions in the game of magic.

This is achieved due to the fact that the device contains an AND circuit, and a ccth delay, which is connected to an oscillator Tacti1 and AND a single-oscillator, the output of which is connected to an And circuit, whose output is connected to a control voltage generator.

The drawing shows the stream (Ktu1rN on the scheme of the proposed u1stroystviya.

The device contains a diode-resistive

elepheptics /, clock generator 2; 1, voltage driver 3, driver 4 of control voltage, delay circuit 5, one-shot 6, circuit 7, block 9, keys 9, gas-discharge display panel 10.

The synchronization of the operation of the entire device is derived from the generator 2 of such a voltage. Forming a world. The voltage 3 is triggered by a TaiKTCiBbiM voltage, and at the outputs /: / and 12, it produces different polarity reference voltage pulses, the amplitude of which is equal to the positive voltage of the cells and allows the lighted cells of the panel 10 to be maintained. the pulses also go through the delay circuit 5 to the electrofluencer 6, from the output of which the pulses of the required duration are fed to the input of the circuit "AND 7. When recording information of the Math unit, LOGI1KI 8, synchronized by the clock voltage generator 2, will generate a voltage And “7. At the same time, the pulses from the output of the one vibrator 6 are passed to the input

control voltage driver 4, which, in turn, produces, at outputs 13 and 14, opposite polarity pulses. As a result, at outputs 11 and 12, shaper 3 with a delay of relatively

reference voltage pulses appear

igniting imllu ss, and so that the positive imjulsu of the reference voltage corresponds to, negative nezh-imigayuschim imuluys, and vice versa. In this case, the voltage swing between outputs 11 and 12 is greater than or equal to the ignition potential of the cells. Keys 9 connected to dio1DO-1resi1Stivnymi elements / affect only the imulses of definite polarity, and on the igniting Imulses. If it is necessary to light the cell located at the intersection of the corresponding element, ro o1b, then the keys 9 connected to the indicated electrodes should be in the closed state. In this case, THEY do not affect igniting and / or pulses, and at the point of intersection of the indicated electrodes, a variety of potential will be created, which is necessary to ignite a cell. Remaining keys

should at the same time be in the open S01STOYIAI

and on the United with, Mn., elec / krodakh, they are present (pulses of apyurny voltage.

Subject invention

An indicator tap containing a gas discharge panel, the outlets of which are connected to the key cutter with a logic unit and through diode-resistive elements to the driver voltage, which is connected to the clock generator, and that, in order to increase the reliability of the device, it contains an AND circuit, a one-shot and a delay circuit, which is connected to the generator of such a voltage, and a one-shot, the output of which is connected to the circuit AND, the output of which is connected to The sponsor is a straightforward voltage.
