Title: Method of setting tension of belt or timing chain
Inventor: KAWAMOTO SHIGERU
IPC: F16H7/12
Filed: 1979-06-22
Abstract: PURPOSE: To set simply and precisely a desired tension of a belt or timing chain, by determining the reaction of a tensioner when the rotation of an engine is at its peak, and pulling the belt by a servo-motor to allow the reaction to become a prescribed value and to set a desired tension in the belt.  
     CONSTITUTION: A crank pulley 5 is rotated by rotation of an engine, and the crank pulley causes, in turn, rotations of a cam pulley 1 and balancer pulley 6 through a timing belt 2. To the belt 2 is applied a tensioner pulley 3 having a rotation center 4 wherein the direction of reaction is designated an arrow A. When the rotation of the engine is at its peak, the tensioner reaction A is measured by a measuring device 7, and then the tensionin the timing belt 2 is caused to become a desired level such that the reaction will reach a prescribed value by pulling the tensioner pulley using a servo-motor or the like. Thus a desired tension is obtained simply, precisely, void of fluctuation without being affected by any influence of statical friction.

IPC: B05D3/06
Filed: 1987-03-31
Abstract: PURPOSE:To efficiently obtain an optical disk substrate which is small in the warpage, optical strain and double refraction of the substrate and has excellent characteristics by subjecting the substrate to precuring by using UV rays of specific light illuminance at a specific dose as energy rays in a pre-stage and subjecting the same to post curing by using UV rays of specific light illuminance in a post stage. CONSTITUTION:A photosetting resin molding material 3 of an acrylic and/or methacrylic system is packed into the spacing between a stamper 4 and a transparent supporting plate 1. The material is subjected to the precuring treatment by projecting the UV rays 5 having 1-20mW/cm<2> light illuminance at 365nm wavelength and 100-1,000mJ/cm<2> integrated quantity of light from a transparent base 1 side and is then subjected to the post curing treatment by projecting the UV rays having 20-300mW/cm<2> light illuminance at 365nm and 20-300mW/cm<2> thereon from the base 1 side to photoset the material 3 from the base 1 side. The warpage and optical strain, and more particularly double refractions of the substrate are thereby decreased as small as to a negligible level.

Title: Stabilizing circuit of servo gain
Inventor: TAKAGI AKIRA
IPC: G11B7/09
Filed: 1984-04-20
Abstract: PURPOSE:To omit the readjustment of a user to disks of different reflection factors by obtaining a laser output which is adversely proportional to the disk reflection factor to keep the servo gain at a fixed level. CONSTITUTION:Laser output stabilizing circuits 3-8-3-16 emit a laser 3-8 with a current flowing to a photodiode 3-9 in proportion to the output light of the laser 3-8 so that the voltage produced at a resistor 3-10 is equal to the reference voltage 3-11 or 3-12. When a disk having a large reflection factor is used, the input voltage of a level deciding circuit 3-7 is reduced. Then the circuit 3-7 delivers a control signal so that an SW3-13 is changed to the lower reference voltage 3-11. Therefore, the output light of the laser 3-8 is reduced to keep the focus servo gain at a fixed level. The focus servo gain can be kept at a fixed level even in case the disk is exchanged as long as the ratio of reflection factors between a disk of a high reflection factor and a disk of a low reflection factor is set equal to the ratio between both voltages 3-12 and 3-11.

Title: Method for discriminating partial discharge at power cable connecting section
Inventor: KASUYA MASAHARU
IPC: H02G1/14
Filed: 1992-02-29
Abstract: PURPOSE:To accurately detect partial discharge so as to prevent the occurrence of a dielectric breakdown by detecting specific ultrasonic waves out of AE waves (elastic wave vibrations) detected by means of an AE sensor (acoustic sensor) and discriminating the partial discharge from a specific waveform contained in the specific ultrasonic waves. CONSTITUTION:Of the AE waves detected by means of an AE sensor 2 provided to a power cable connecting section 1, ultrasonic waves of >=20kHz generated in the section 1 are outputted to a waveform length discrimination circuit 5 by intercepting ultrasonic waves other than those of <=20kHz generated in the section 1 through a filter circuit 4. The circuit 5 detects partial discharge generated in the section by detecting waveforms having length of <=5msec which is characteristic to the partial discharge by intercepting waveforms having lengths of >=5msec. Therefore, the occurrence of a dielectric breakdown can be prevented, because partial discharge generated at the power cable connecting section can be accurately discriminated without erroneously discriminating external noise generated in the vicinity of the connecting section as the partial discharge.

Abstract: PURPOSE: To facilitate grinding and also to enable a smooth turning with a load capacity increased, by a method wherein steel wires are caulked into grooves made in a circumferential direction of an outer and an inner ring, and a surface of the steel wire is ground in a concave R-shape.  
     CONSTITUTION: Steel wires 5EW5H are caulked into circumferential grooves 9EW 9H made in an outer ring 1 and upper and lower rings 2 and 3, and the steel wires, united with the outer ring 1 and the upper and lower rings 2 and 3 to form a completely monolithical object, are then grinding-finished in a concave R-shape. Working errors accumulated in the outer ring 1 and the upper and lower rings 2 and 3 in a first process are all corrected by the grinding-finish, and a section where a rotating object 4 and the steel wires 5EW5H make contact with each other is maintained within an extreme minor error range. Grinding of the steel wires 5EW5H can be completed in a short time because of the small volume thereof. Besides, a contact portion with the rotating object 4 is formed in the concave R-shape, and thereby a device can correspond to the increase in a load capacity and the movement of a contact point resulting from the somewhat deformation due to a load, which results in permitting the smooth rotation.
