Title: Fabrication of disc type rotor for synchronous motor
Inventor: OKU HIDEAKI
IPC: H02K1/27
Filed: 1986-02-14
Abstract: PURPOSE:To dispense with a positioning jig by magnetizing necessary numbers of magnet elements one by one and by arranging and bonding these magnet elements so that the polarity may be different between one another for the magnet elements adjacent to both sides of a dough-nut-like metal plate. CONSTITUTION:A segmented flat-shaped magnet element 2 is punched by yokes 6 and 6' of a magnetizing device and a coil 7 is electrified to magnetize the magnet element. As this magnetization is performed individually for each magnet element 2, the yokes 6 and 6' are to be large enough for the magnet element 2 so that the flux density may not be lowered at the end tip portion of the magnet element 2. Thus, the required numbers of individually magnetized magnet element 2 are arranged so that the magnet elements of different polarity may come side by side to each other on both sides of a metal plate 1 of high permea bility in doughnut-like arrangement by applying an adhesive to the surface to contact with. Thus, it is not necessary to press with a positioning jig from upper and lower sides to fix them.

Abstract: PURPOSE:To perform the clear reproduction of a still picture with two heads, by connecting slidably the head on one side with the same track recorded in the same azimuth repeatedly, converting a signal to a video signal, and outputting it after delaying by one horizontal scanning period by a delay means. CONSTITUTION:When the heads R and L are connected slidably with a recording tape 2 with the same locus C being superposed on the same track TR recorded in the azimuth of the head R, the signal is reproduced from the head R on one side, and no signal is outputted from the head L on the other side since the azimuth is different. And while the head is connected slidably with the recording tape 2, the contact (a) of a head switch 6 is controlled so as to be connected to a common terminal (c), and the output of the head R is supplied to a video reproduction processing circuit 10 at every two horizontal scanning periods. Therefore, the video signal is supplied from the video reproduction processing circuit 10 to an output terminal 12 and a delay circuit 13 at every two horizontal scanning periods. And the video signal delayed only by one horizontal scanning period is supplied from the delay circuit 13 to the output terminal 12. In such a way, it is possible to perform the clear reproduction with high definition of the still picture.
