Abstract: PURPOSE:To reduce a torque ripple and cogging by driving a motor device, etc., by switching and changing the amplitude of switching pulses in response to the operation of the motor device, etc. CONSTITUTION:A drive controller has a speed amplifier 51, current amplifiers 52-54, a three-phase sine wave generating circuit 55, a rotor-position detector 56, a triangular wave generating circuit 57, comparators 58-60, drivers 61-66, an output variable power circuit 67, a transistor bridge 68, a DC brushless motor 69 connected to the bridge 68, a rotary encoder 70, a speed detector 71, etc. A speed feedback signal 502 by the speed detector 71 is subtracted from a speed reference signal 501, and a speed command 503 is generated through the speed amplifier 51. On the other hand, the current feedback signals 523-524 of the motor 69 are extracted, and the signals corresponding to each phase are subtracted from said speed command 503, and values acquired are output through the current amplifiers 52-54. Accordingly, the amplitude of driving power supply pulses is also changed to a sine wave shape in response to the operation of the motor 69, thus reducing cogging, etc.

Title: Developer for electrostatic latent image
Inventor: MATSUBARA AKITOSHI
IPC: G03G9/087
Filed: 1987-08-21
Abstract: PURPOSE:To prevent toner filming on a photosensitive body and damaging of a cleaning blade and the photosensitive body by mixing fine polyester resin particles with a toner. CONSTITUTION:The fine polyester resin particles smaller in average particle diameter than the toner particles are mixed with the toner particles, and electrostatically and/or physically attached to the surface of each toner particle. The toner particles to be attached to the surface of the photosensitive body come into contact with said surface by the medium of said fine resin particles comparatively soft and small in surface energy, and also small in adhesive strength, thus permitting the toner filming on the surface of the photosensitive body to be prevented and damaging of said surface and the cleaning blade to be avoided.

Title: Divided type boot, joining method therefor, welding agent and heating body
Inventor: INUZUKA YASUAKI
IPC: F16D3/84
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To improve seal performance and fatigue strength at divided end parts joined each other of a divided type boot and to improve workability at the time of mounting the boot. SOLUTION: A projecting streak 16 formed at a divided end part 14 of a boot is temporarily coupled with a recessed streak 17 formed at the other divided end part 15 in engaged states of engaging difference of level parts 162a, 172a each other formed on the one side and is joined with the recessed streak 17 by welding, fusion or adhesion. By joining a polymerized projecting streak 173 formed on a non-engaged side (an inner peripheral side) of the recessed streak 17 by striding the streak 173 over an inner peripheral surface 16a of the projecting streak 16 and an inner peripheral surface 14b of the divided end part 14 continuous to this inner peripheral surface 16a, large joining area is secured. Because the projecting streak 16 is engaged on only one side, the insertion resistance is reduced.  Because the polymerized projecting streak 173 becomes a guide at the time of the insertion, a temporary coupling work becomes easy. Thickness of the divided end parts 14, 15 is reduced and fatigue durability can be improved.

IPC: C23C26/00
Filed: 1988-08-23
Abstract: PURPOSE:To form a uniformly hardened layer on the sliding surface of a cam by increasing the supply rate of the gaseous plasma to the rising part of the sliding surface of the cam to the rate larger than the supply rate to the falling part at the time of subjecting the sliding surface of the cam to a remelting and hardening treatment by a plasma torch. CONSTITUTION:The plasma torch 38 is displaced to advance and retreat in the major axis direction of a cam shaft W in proximity to the sliding surface 60a of the cam 60 and the shaft W is rotated in a direction D. A high voltage is impressed simultaneously between a tungsten electrode 44 and the shaft W to generate a plasma arc 32. A shielding gas is ejected from a passage 40a and a pilot gas is ejected from an ejection port 42b. The sliding surface 60a is irradiated with the plasma arc 52 and metal powder is supplied from a supply port 38c to execute the remelting and hardening treatment. The amt. of the gaseous plasma to the rising part (a, b, c1) of the sliding surface 60a of the cam is selected to the value larger than the amt. of the gaseous plasma of the rising part (C2, d, e). The generation of the deformation on the sliding surface of the cam is prevented in this way and the hardened layer having a uniform thickness is formed.

Title: Recording and reproducing device
Inventor: KAJI TOSHIO
IPC: G11B5/027
Filed: 1985-09-20
Abstract: PURPOSE:To prevent an unnecessary signal from being transferred from a head to a recording track by switching a recording mode to a reproducing one, for instance, at a head switching point after the head is moved to a guard band. CONSTITUTION:When three pulses (e) come in a step motor 6, the head 2 moves by a half track only. The motor 6 becomes 'normal feed' conveying the head 2 in a track internal periphery direction and 'reverse feed' conveying the head in a track external direction when a switching pulse (f) deciding the feeding direction of a motor 6 comes to a high level and a low level, respectively. Here it is assumed that recording is completed at a point of time t1. When a step motor driving pulse (e) is transmitted, the head 2 moves to the guard band being a half track off in the internal peripheral direction, because the pulse (f) is at a high level. Polarities of switching pulses at points (a) and (b) are inverted, and the recording mode is switched to the reproducing mode. The pulse (f) is simultaneously changed to a low level, and the pulse (e)moves the head 2 by a half track and returns it to the previous track. Thereby the recorded signal is reproduced.

Title: Position detecting device
Inventor: NOSE TETSUSHI
IPC: H01L21/027
Filed: 1989-08-14
Abstract: PURPOSE:To miniaturize the device and to enable high-accuracy detection by sharing some of physical optical device on a mask and a wafer. CONSTITUTION:A combination of Fresnel zone plates is set on the mask 2 and wafer 3, A and B detects a lateral position shift, and B and C measure the interval. In this case, the interval detection does not depend upon the lateral position shift and the lateral position shift detection has no interval dependency. Further, even if the wafer 3 tilts, variation in spot interval is not caused by the wafer tilt because both xy-plane shift detection and interval detection use information on the interval between two spots. Further, even if a projection system for incident luminous flux 1 and an alignment gap detection system where sensors 4 and 5 are held shift slightly and relatively from the mask 2 and wafer 3, no error is generated because the xy-plane shift is detected from the interval between spots 81 and 82 and the surface interval between the mask 2 and wafer 3 is detected from the interval between spots 82 and 83.
