Description

Known methods for manufacturing miniature resistivity in CTCK.iHHHoi insulation by means of), and the winding of this microwire on the tubular glass frameworks with its heating when applied to the frame-do not provide the possibility of HociTi to perform max. conductive elements used in TOMHofi equipment.

According to the described method, the luiMOTKa microfibers are produced on the frame, heated by 1 g out of the ground electric current, which reduces the mechanical stresses in the glass insulins and reaches the microwires of the microwire on the frames with a diameter of several tenths. For the insulator, an equivalent of this method is carried out in a built-in glass tube, a wire and a metal rod (core) and welded to it.

To form two current leads to the core wire of the skeleton, it can heat the current through it to melt the middle part of the core and disintegrate eiO Ia two isolated one from each other part, used as current leads.

rod, in chain P 0 b.yphosis from the tube, the end of the cylinder. Brazing is made by silver in the manner described in the ed. St. 104209.

Then the current is passed through the rod again, thus the carcass is heated up to the required temperature and brought it back into it. At the same time, the micron of the current, the end of which is irradiated to the rod, is first wound on the rod section between the point naiJKH and the beginning of the glass tube, and then after several turns on the surface of the tube and forms a one-sided 1st and.: 1and multilayer winding.

The microconductor is heated on the surface of the frame, which is heated from the surface and therefore is wound up with a strain that creates plastic deformation of the glass insulation on the frame and the section of the winding with each other and the glass frame of the frame.

After the end of the plug, the end of the microwire descends from the tube, makes several turns on the free end of the rod, and after stopping the machine it is soldered to this end in the indicated manner.

Then a rod with a pomotic resistance is again brought into rotation and is gradually heated by the current flowing through it until the rod melts inside the frame and the rod breaks into two insulated ones.

pieces, which, being welded to the ends of the tube, now become current leads of wound M1n roprovolnogo resistance.
