Description

one

The invention relates to instrumentation and can be used in information recording systems, in particular, in automatic drawing apparatus.

The aim of the invention is to improve the recording quality by creating additional pressure in the rapidograph.

FIG. 1 shows a block diagram of the device in FIG. 2 - time diagram of the device.

The device contains a power supply unit 1, a shaper 2 short pulses, a key 3, a key 4, an electrodes 5 and 6 of the racograph, a limiting element 7, a rapidograph 8.

The device works as follows.

The device for controlling the plotter (Fig. 1) generates a lowering signal of the 2-hour graph, which is fed to the input of the short pulse generator 2 and controls the operation of the key 3. The key 3 closes the circuit and the potential at the point shown in Fig. 2c. At the output of the shaper 2 short pulses, a signal L of the type shown in Figure 2B is generated. Key 4 is in the closed state for a time determined by shaper 2 short pulses. The potential point - electrode 5 rapograph has the form shown in figs.

The potentials of the listed points are measured relative to the electrode 6 of the rapidograph, which is connected to the power supply unit 1. Thus, the proposed 5 my device, in comparison with the SIV, allows at the initial moment of the rapidograph lowering signal to ensure the passage of a current pulse through the solution subjected to electrostimulation with an amplitude determined by the resistance of the solution and the duration determined by the shaper of short pulses.

The pulse duration of the short pulse shaper is shorter than the slow pulse of the rapidograph when the point is drawn. The presence in the structure of the former 2 short pulses and a key. 4 provides at the initial moment the magnitude of the pressure impulse sufficient to overcome the forces of the surface tension of the carcass in the rapidograph; there is a destruction of the carcass film, resulting from drying of the carcass.

The rapidograph contact with the surface occurs simultaneously with the formation of a droplet under the action of a pressure pulse.

.Application of the device will improve the recording quality, significantly reduce the time of machine design, no products, and also reduce the loss of paper, which leads to efficient use of ink.
