Abstract: PURPOSE:To obtain a control apparatus of a motor which is resistant to a noise and avoids a dangerous state for safety's sake by a method wherein a switching state of an inversion means is detected as an optical signal and this optical signal is transmitted to a control means. CONSTITUTION:An alternating-current output from an alternating-current power supply 1 is converted into a direct current by using a power rectifier 2; this direct-current output is converted into an alternating current corresponding to a motor velocity by using an inverter 4 constituted of a transistor; the transistor of the inverter 4 is controlled on the basis of a pulse-width modulation by using a control means. Then, the transistor of the inverter 4 is detected by a switching-state detection part 17; this detection result is output as an optical signal; the optical signal of the switching-state detection part 17 is transmitted to the control means by using an optical transmission means; the control means drives and controls the transistor of the inverter 4 on the basis of the optical signal of the optical transmission means. The switching-state detection part 17 is provided with resistances 19, 25 which limit an electric current flowing to optical modules 18, 24, 30 with built-in light-emitting elements.

Title: Rotary head assembly
Inventor: SUGI HIROMI
IPC: F16C17/10
Filed: 1987-08-31
Abstract: PURPOSE:To inexpensively offer a rotary head assembly with high accuracy and sufficient strength and excellent slidability, by using a metal-made or ceramic-made housing for a stationary cylinder and providing a synthetic resin coating layer to a tape running part. CONSTITUTION:The housing 20 being a core of a stationary cylinder 16 arranged under a rotary cylinder 2 is made of an aluminum alloy diecast and its outer peripheral face is covered by a synthetic resin coating layer 20B and a tape running part 21 made of a tape running face 21A and a read step face 21B is formed to the synthetic resin coating layer 20B. Thus, the NC precise processing for a long time is not required and mass-production is attained inexpensively. Since the synthetic resin coating layer 20B is lined by the housing 20 with thin but high rigidity, deformation such as bent, warpage or creep due to plastic forming is not caused and the accuracy of size and strength are ensured sufficiently.

Title: Device for housing/refeeding paper
Inventor: JIYOUDAI AKIYOSHI
IPC: B65H83/02
Filed: 1988-08-31
Abstract: PURPOSE:To rapidly move an end restricting member by providing a control means for controlling a driving means in such a way that the restricting member is moved at a first speed of high speed from a defined position to a position immediately before the position corresponding to the housing-direction length of paper while moving same at a second speed lower than the first speed up to the position corresponding to the housing-direction length of paper. CONSTITUTION:An end restricting member 140 is moved to a position immediately before the position corresponding to the housing-direction length of paper at a first speed of high speed right before a paper housing operation and, after that, moved to the position corresponding to the paper housing-direction length at a second speed of low speed. Thereby, the end restricting member 140 can be moved to the position corresponding to a paper size rapidly and accurately. Also, since the end restricting member 140 restricts the housing-direction end of a sheet of paper in a position corresponding to the paper size, the sheet of paper may travel in the housing portion only by the minimum distance, greatly reducing the probability of causing inferiority or impossibility of housing.
