Title: Fuel injection valve for internal combustion engine
Inventor: KAARU HOOFUMAN
IPC: F02M61/16
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To obtain good sealing performance at all times by curving at least one of end surfaces moved together with each other of a valve main body and an intermediate disk plate toward an outside in a spheroidal shape, in a device formed in such a constitution that the intermediate disk plate is interposed between a valve body and a valve holding body. SOLUTION: The valve main body 1 of a fuel injection valve is tightly fitted to a valve holding body 5 through an intermediate disk plate 7 by a tightly fitting nut 3. The valve main body 1 is provided with a bag hole 11 extending from an end surface 9 adjacent to the intermediate disk plate 7, and a piston shaped valve member 13 is slidably fitted and inserted therein. A spring chamber 31 opened toward the intermediate disk plate 7 is formed in the valve holding body 5, a valve member 13 is energized by a valve spring 29 housed in the spring chamber 31 so as to seat the valve member 13 to a valve seat 15. In this case, since uniform force is led into a seal surface formed between the intermediate disk plate 7 and the valve main body 1, one of a seal surface 47 which is moved together with each other is curved toward an outside in a spheroidal shape.  It is thus possible to ensure good sealing performance.

Title: Alignment device
Inventor: SATOU KUNINAGA
IPC: B23Q17/24
Filed: 1987-01-06
Abstract: PURPOSE:To make a device inexpensive, by using two cameras, catching two marks on an object on a transfer table each separately with each corresponding camera, and taking an important point of a rotary mechanism of a positioning table at a position apart in the radial direction form a turning center of the table. CONSTITUTION:Corresponding to each position of two marks 2 and 3 on an object, two cameras 4 and 5 are used so that even if a distance of these marks between two points is made larger to raise measuring accuracy in rotation, these is unnecessary to lower the camera's magnification, so that three axes of X, Y and theta all are possible to do highly accurate measurement, thus highly accurate alignment is performable. And, owing to a rotary mechanism of a positioning table 6, compensation of a tilt angle gets off with calculation of the value equivalent to a difference in the Y direction without using a trigonometric function, so that operation is simplifiable, and simultaneously since indexing an angle of high resolution becomes unnecessary, so that a simple device is realizable from the mechanical standpoint. Therefore, it can be made into such one that is inexpensive and that highly accurate.

Title: Refrigerant compressor
Inventor: FUKUDA KATSUMI
IPC: C10M133/44
Filed: 1996-01-09
Abstract: PURPOSE: To realize a highly reliable refrigerant compressor which can withstand a prolonged application using excellent oil of a refrigerant machine allowing the using of fluorocarbon 134a or the like as alternative refrigerant of fluorocarbon 12 in conformity with the regulation of fluorocarbon. CONSTITUTION: An oil of a refrigerating machine with which a closed container of a refrigerant compressor is filled is produced by adding a moderate amount of an epoxy compound having more than one epoxy group in a molecule and moreover, a phenol based anti-oxidation agent preferably to the oil of the refrigerating machine such as an ester oil, alkyl benzone or mineral oil. The epoxy groups open the ring thereof to trap acid formed by a reaction between a refrigerant and the oil or the refrigerant and water thereby improving resistance of the oil to the refrigerant significantly. This can prevent corrosion, wearing and damage of a slide part of the compressor as caused by a rise in the total acid value of the oil, copper plating phenomenon or the like, thereby enabling the realization of a highly reliable refrigerant compressor.

Inventor: YONEYAMA RYOICHI
IPC: H01L23/522
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To provide sure contact with a very simple process, by so dry-etching that even a substrate under a conductive layer or a part of an insulation film is etched while the insulation film and the conductive layer are penetrated. SOLUTION: After a photo-resist film is applied on an insulation film 102b where a contact hole is to be formed, a resist film 103 which has an opening 103a is formed at a contact hole formation part. Then, with a resist 103 as an etching mask, an opening part 104 is formed at insulation films 102a and 102b by anisotropic dry-etching. Here, by performing dry-etching longer than the time-period with which the opening part 104 reaches the surface of a conductive layer 101, a contact hole 104 slightly lower than the surface of a substrate 100 is formed through the insulation films 102a and 102b and the conductive layer 101. Then, with the resist film 103 left out, a wet etching is performed with an etching liquid whose selection ratio between an insulation film and conductive layer is large.

Title: Shared memory management method
Inventor: ANAMI KAZUHIRO
IPC: G06F12/00
Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To attain an exclusive access via an application program almost with no consciousness and also to improve the convenience for production of the application program. SOLUTION: A multi-task operating system 3 has a virtual storage mechanism which generates an exception and manages a memory when an application has an access to a memory space where no physical memory 11 is allocated. In such an operating system, the memory space of a shared memory is added to the memory space of the application, and the memory 11 is not allocated to any application. Then an exception is generated when the application has an access to the memory space. If the access object area included in the shared memory is not occupied by another application when the exception is generated, the memory 11 corresponding to the preceding area is allocated to the preceding application. At the same time, the corresponding area is set in an occupation mode. Thus the accesses of other application can be excluded.

Inventor: KAWAI HIDEYUKI
IPC: B21D24/00
Filed: 1988-01-08
Abstract: PURPOSE:To form roundness in a parting part without generating cracks by elongating the neighborhood of a parting part as an upper die is being lowered, drawing a work reversely increasing liquid pressure in a lower die shell and forming a roundness small in radius at the parting part of the work. CONSTITUTION:The work 26 mounted on the upper surface of the lower die shell 24 full of liquid 23 is held between blank holders 28, 30 and when the upper die 22 is lowered, a flexible guide punch 32, too, provided on the side wall of the upper die 22 is lowered. The work 26 is pressurized by the lower end part of the guide punch 32 downward to elongate the neighborhood of the parting part 26a. When liquid pressure is increased as the upper die is lowered further, the work 26 is drawn reversely, the parting part 26a becomes smoother and small roundnesses hard to crack and small in radius are formed at parting parts. Since small roundnesses can be formed in one die, it is possible to present a molding die which does not require bending operation in forming roundness small in radius and excells in work efficiency.
