Description

The invention relates to computing texHHKe and can be used in integrated circuit control devices on cylindrical magnetic domains (CMD).

The purpose of the invention is to simplify the source of a rotating magnetic field.

FIG. Figure 1 shows the source of the rotating magnetic field; general appearance; in fig. 2 - inductance coil, general view; in fig. 3 is a series diagram of the connection of individual sections of the inductor.

The source of the rotating magnetic field (Fig. 1) contains two inductance coils 1 and 2 with a cross section in the form of a rectangular meander and double-sided printed circuit boards 3 with conductors corresponding to the wiring diagram of the individual sections 4 (Fig. 3). Into the coils 1) and 2 are inserted the bases 5 with the home-containing crystals. The harvesters 6 of the respective sections (Fig. 2) are used to connect coils 1 and 2 to current sources.

The proposed source of the rotating magnetic field works as follows.

for both odd and for a number of bases, while the design of the known device allows only

5 odd number of bases.

Due to the superposition of the magnetic fields created by each section of the coils, the strengths of the magnetic control fields are the same or

 They are admissiblely different with an even number of half-periods of the meander, and with an odd number, they differ significantly.

The design of the proposed device for two is optimal.

If the number of conductors in each section is the same, the intensity of the rotating magnetic field

20 decreases from the middle of the coil to its edge by 40-50%, with the main decline occurring at the edges of the coils, which is characteristic of all sources of the field of engraving. Proposed technical

25, the solution allows the floor voltage to be reduced to a few percent by applying different numbers of conductors in the coil sections, and thereby increasing

30 permissible source area for placing magnetic integrated circuits.

When applying sinusoidal current S1I sawtooth, shifted in phase by 90, the terminals of coils 1 and 2 between the corresponding sections 4 give rise to four regions of the rotating magnetic field of motion control of the CMD, so that on each base four magnetic integrated circuits or four groups of crystals can be placed with synchronous movement of cylindrical magnetic domains in each crystal. . Since all bases with crystals can be installed in the source without being covered by windings from all sides, the proposed device is structurally simpler than the known one, in which half of the bases with crystals should be necessarily covered with coils from all sides.

In addition, the design of the proposed device allows to implement
