SU392485A1 - INKJET SHIFT REGISTER - Google Patents

Description

one

The invention relates to the field of automatic control and can be applied in pneumatic computing devices.

An inkjet shift register is known, which contains at least two close cells and two clock channels, one of which is connected to even and another one is odd, and a trigger with counting input, containing a memory element and a control circuit.

Such a device has low reliability due to the fact that the clock pulses generated at the outputs of the trigger with a counting input can be equal to one for a certain period of time, which leads to malfunction of the device.

The proposed inkjet shift register, containing an obegani circuit, two clock channels connected to it, and a trigger with a counting input, made in the form of a memory element and a control circuit, whose output channels are connected to the memory element, are reliability of the register, in it the channels of clock signals are connected to the input channels of the control circuit.

This allows the register clock pulses to be separated in time, which

eliminates the simultaneous appearance of single signals in both clock channels and increases the reliability of the device.

Pa figs. 1 shows the register structure; in fig. Figure 2 depicts the scheme and sequence diagram of the trigger with the counting input. The inkjet shift register (Fig. 1) consists of a circuit / run with channels 2 and 5 clock signals and a counting trigger 4

with a control circuit 5 and channels (3 and feedback). The counting input 8 of a flip-flop is the input of the entire device.

A trigger with a counting input (Fig. 2) consists of a control circuit formed by the logic elements L and L-, the blocking element / 7h, and the memory element T. Each logic element has two control inputs 5 and W, one inhibit input 7 / and two outputs / 2 and V3, and the memory element has two installation inputs 14 and 15, one reset input 16 and one output / 7.

The trigger operation is characterized by the fact that single signals at the outputs of the control circuit are separated in time by an interval

equal to the interval between the counting pulses, as shown in the sequence diagram (Fig. 2). Inkjet shift register operates as follows.

When a signal is applied to the trigger trigger input, a signal appears in channel 2 (if

This MOMeHt contains a single signal at the output 13 of element L, or a signal in channel 3 (if there is currently a single signal in channel 12 of the element L. These signals are clocking pulses that control the shift register and are separated in time by the interval determined by a pause between pulses at the counting input of the trigger.This eliminates the possibility of a through passage of the shifted number through two or more cells in the run-around chain.
