Title: Refrigerator
Inventor: YAMAZAKI SUSUMU
IPC: F25D23/02
Filed: 1991-05-14
Abstract: PURPOSE:To obtain a power saving effect and to perform smooth door opening and closing operations by lapping a guide inside a refrigerator and a peas at the side of a rotary partition, and providing a protrusion for reducing a surface-contact range of a slide of the piece with the guide near an inlet of the guide. CONSTITUTION:At the time of sliding guides 17, 18 and upper and lower pieces 12, 13, an area of a surface contact is reduced by protrusions 23 on guides 17a, 18a. Particularly, at the time of advancing a rotary partition to the guides 17, 18, a lock of the slide 13c of the partition 7 due to surface contact of a large area with the guides 17, 18, is eliminated. Thus, a state that the partition 7 is locked on the way of rotation to completely close doors 3, 4, i.e., a state that gaps occurs between the doors 3, 4 and the partition 7 to leak chilled gas from the gaps, can be prevented.

Title: Mounting method of semiconductor chip
Inventor: KAWASHIMA AKIHIRO
IPC: H01L21/60
Filed: 1992-04-27
Abstract: PURPOSE:To eliminate the need for the removal of residual paste difficult to be removed after curing by conducting rework when conductive paste is brought to a semirigid state after bonding and performing main curing after all IC chip are changed into nondefectives. CONSTITUTION:A reaction progresses in a certain extent at a temperature of approximately 100 deg.C in conductive paste used for bonding a semiconductor chip mounted on a liquid-crystal cell substrate, and nondefective or defective semiconductor chips can be decided by electrical inspection. Consequently, the IC chips decided as defectives by an electrical check after temporary curing are removed by a head 3 for removing the chips. Residual paste 6 is left as it is on a panel 2 at that time, but a nondefective IC chip 8, on which paste is transferred, is bonded from the upper section of residual paste, temporary curing is conducted again, and main curing is carried out after all IC chips mounted by electrical inspection are changed into nondefectives. Accordingly, a troublesome work process can be executed simply.

Title: Alloy
Inventor: SAWASHITA AKIO
IPC: A01K63/00
Filed: 1979-08-23
Abstract: PURPOSE: To enhance the corrosion resistance, wear resistance and stainproof of a Cu alloy by plating the alloy with Cu.  
     CONSTITUTION: By plating a 40W75% Cu-contg. alloy with Cu, the galvanic corrosion of the alloy can be preventd even if the Cu plated layer is scratched or worn. The alloy is excellent in corrosion resistance and wear resistance by itself, yet it lacks in stainproof. By plating the alloy with Cu, a special Cu alloy layer of the alloy and Cu is formed to give an alloy having corrosion resistance, wear resistance and stainproof. In addition, patina formed on the alloy surface is hardly peeled off, causing no pollution.

Title: Capacity controlled type room air conditioner
Inventor: SERIZAWA YUKIO
IPC: F04B49/00
Filed: 1981-07-13
Abstract: PURPOSE:To enable to change the capacity of a room air conditioner freely to a desired level, by connecting a stepped bore having a structure of check valve to a cylinder of a compressor and a by-pass pipe that is communicated to a low- pressure section of a refrigerating cycle having a stop valve and a small tube arranged in parallel to each other. CONSTITUTION:With closing of a stop valve 22 during rated operation of a compressor, pressure in a space 33 defined between the stop valve 22 and a valve plate 24 is raised with time and finally becomes substantially equal to pressure P H in a compression chamber 9 at the time when a rolling piston 13  comes to a position of the setting angle thetaH of a stepped bore 19 opened in a  cylinder 11, so that the valve plate 24 is rendered immovable and an rated output can be obtained. This is because the valve plate 24 is opened each time the rolling piston 13 is turned and pressure in the space 33 is raised. However, the  pressure is not dropped since the valve plate 24 is forced back onto a valve  seat 20' by the force of a spring 25 just after the piston 13 passed through the  crank angle thetaH. The above principle holds true irrespective of the setting angle  thetaH of the stepped bore 19.

Abstract: PURPOSE:To raise the safety of an oil-pressure operator by providing a guide regulator coupled with the elevating guider of an operating lever but not coupled with the inside of a tilting guider to a lever shaft in a manner that its position can be freely altered or fixed. CONSTITUTION:In vertically moving or tilting a boom 5 attached to a vehicle 1 and an operator 7 attached to the tip of the boom 5 by tilting cylinders 6 and 8, an operating lever 26 is operated along guiders 31 and 32 for elevating and tilting purposes.

Filed: 1990-04-25
Abstract: PURPOSE:To improve the stopping accuracy by making a contact member abutting on the edge of a 1st stop pattern and the edge of a 2nd stop pattern the same in position. CONSTITUTION:This encoder printed board 14 is positioned not opposite the edge 18b-1 of a standard photography stop pattern 18b and the edge 18c-1 of a telephotography stop pattern 18c, but on the same side, and the distance L between those edges 18b-1 and 18c-1 is regarded as an extension quantity between standard photography and telephotography. If excessive or deficient etching about the distance L is caused, variation due to the excessive or deficient etching of the stop patterns 18b and 18c becomes an increase or decrease to cancel the excessive or deficient etching, so that the distance L has a little variation. Consequently, the stop accurate is improved.

Abstract: PURPOSE:To release internal stress by dividing a molded body at the specific part and to obtain the molded body having no defects such as the residual and the like of an internal distortion by a method wherein the axis of easy magnetization of the magnetic powder in the molded body is oriented in radial direction, the entire molded body has a cylindrical shape, and a groove extended in axial direction is provided on the internal circumferential surface of the molded body. CONSTITUTION:A molded body 10 has a cylindrical shape in which the axis of easy magnetization of magnetic powder is oriented in radial direction, and a groove 12 extending in axial direction is provided on the inner circumferential surface of the molded body. Said groove 12 is formed at two places in such a manner that it has an angle of 180 + or - 5 degrees or thereabout against the center axis. When said anisotropic cylindrical molded body 10 is sintered, the fractured surface is formed very neatly in the shortest distance in the sintering treatment, namely, it is broken in radial direction. As the large internal stress generated by the difference in degree of shrinkage is concentrated in the groove 12, the generation of microcracks on other parts is prevented, and the molded body is divided into two parts at the position of the groove 12. As a result, the internal stress disappears, and the internal distortion is not left.
