Filed: 1992-10-07
Abstract: PURPOSE: To obtain a liquid-tight fastening by using a first elastic plastic bushing and a metal end cap which is covered by the outward/backward-expaned bushing when a screw is tightened. CONSTITUTION: A bushing 10 made of neoprene, nitrile rubber, etc., is inserted into a hole 12 of a thin wall 14, and an attachment member 18 to be fixed on the wall 14 is mounted on the flange 16. A screw 20 is screwed to a stamp aperture 22 of a metallic end cap 24 through a bushing 10, and the metallic end cap 24 is engaged with a reduced diameter part 26 of the bush 10. When the screw 20 is tightened, the reduced diameter part 26 is pressed inwardly against the screw 20, and if a stronger force is applied, an increased diameter part 32 of the bushing 10 is expanded outwardly to cover an open end 28 of the metallic end cap 24, and the open end 28 is subject to an inward-radial force. A result is that the metallic end cap 24 is centered to obtain a liquid-tight fastening.

Abstract: PROBLEM TO BE SOLVED: To reduce the deformation, improve the flatness and reduce the surface vibration of a magnetic disc by a method wherein the surface roughness of one of the surfaces of a plastic disc-type nonmagnetic substrate which is formed by injection molding or injection compression molding is set to be not larger than a specific value and the surface roughness of the other surface is set to be not less than a specific value and magnetic layers are formed on both the surfaces. SOLUTION: A 1st stamper whose transfer surface has a surface roughness of not larger than 2 nm and a 2nd stamper whose transfer surface has a surface roughness of not less than 4 nm are placed in a mold for injection molding or injection compression molding. If a disc-type nonmagnetic substrate 1 is formed by the injection molding or the injection compression molding of plastic which is substrate material by using the mold, the patterns of the respective transfer surfaces of the respective stampers are transferred onto the nonmagnetic substrate 1. That, is, the surface roughness of one 1a of the surfaces of the nonmagnetic substrate 1 is not larger than 2 nm and the surface roughness of the other surface 1b is not less than 4 nm. Magnetic layers 2 and protective layers are formed on both the surfaces.  With this constitution, the deformation of the substrate when the substrate is removed from the mold can be reduced, so that the flatness of a magnetic disc can be improved and its surface vibration can be reduced.

IPC: G01M1/16
Filed: 1991-10-17
Abstract: PURPOSE:To accurately correct an unbalanced wheel by detecting the acceleration of a lower arm in the longitudinal direction and finding the unbalanced amount and position of the wheel from the amplitude and phase of the waveform of the detected acceleration. CONSTITUTION:While a wheel 2 is rotated, the vibrating acceleration of a lower arm 9 vibrating in the longitudinal direction is detected 10. The detected signal is subject to spectrum analysis 12 and the waveform of the vibration acceleration is obtained by only extracting the frequency component generated by the unbalanced state of the wheel. 2. The obtained waveform is outputted to a data processor 13. The amount of the amplitude and phase of the acceleration waveform correspond to the unbalanced amount and position of the wheel 2. The processor 13 finds the phase phi of the acceleration waveform to a reference pulse P inputted from a phase detector 16 by comparing the inputted acceleration waveform with the pulse P. At the same time, the processor 13 also finds the amplitude A of the acceleration waveform and outputs the phase phiand amplitude A to a recorder, etc. Then the unbalanced amount and position of the wheel 2 are found from the amplitude A and phase based on a tuning chart obtained from previously conducted experiments.

Title: Method and device for molding ceramic green sheet
Inventor: YOSHIMURA TOSHIMI
IPC: B28B1/30
Filed: 1989-10-16
Abstract: PURPOSE:To prevent fluctuation of thickness in a ceramic green sheet by allowing ceramic slurry to flow along a gradient face and thereafter supplying this ceramic slurry to the gap between a metering roll and a coating roll. CONSTITUTION:Ceramic slurry 9 is allowed to flow along a gradient slope and thereafter supplied to the gap between a metering roll 2 and a coating roll 3. Therefore the pressure exerted from ceramic slurry 9 supplied to a slurry dam 10a is buffered by the gradient face or a gradient face forming member. Thereby it is nearly completely prevented that a turbulent flow is generated and undesirable fluctuation of pressure is caused for the ceramic slurry 9 which starts to be supplied to the gap between the metering roll 2 and the coating roll 3.

Filed: 1990-10-08
Abstract: PURPOSE:To obtain an optimum temperature characteristic for the power amplifier by providing a temperature sensor, a radiator for a heat sink, a Peltier element and a control section for current control of the Peltier element to the unit. CONSTITUTION:A temperature sensor 1 detects a temperature rise of an aluminum block 4 and a control section 5 controls a DC voltage applied to a Peltier element 2 fixed to the block 4. For example, when the temperature rise of the FET 7 is high, a current flows to the N pole of the element 2 to the P pole, the DC voltage gets higher, a heat in the FET 7 is absorbed forcibly by a pumping actin of the element 2 and is dissipated toward the heat sink radiator 3 in contact with the other face of the element 2. The control section 5 applies current control by the temperature detection information of the sensor 1 in this way and the heat in the FET 7 is controlled within a permissible temperature.
