Title: Liquid level measuring instrument for fuel tank
Inventor: SASAKI MICHIAKI
IPC: B60K15/077
Filed: 1987-03-02
Abstract: PURPOSE:To prevent a read switch from hunting owing to variation in the liquid level in a tank main body by forming a float chamber in the tank main body and operating the reed switch by a float provided in the float chamber. CONSTITUTION:A suction pipe 28 for fuel is inserted into the tank main body 1 and the float chamber 32 is formed at the periphery of the tip end part of the suction pipe 28. The float chamber 32 is equipped with an intake 38 linked with the tank main body 1 at its lower part, and the float 35 and the reed switch 33 which operates following up the float is provided therein. Consequently, the float 35 is provided in the float chamber insulated from the tank main body by a partition wall 31, so even when the liquid level of the fuel in the tank main body fluctuates, abrupt fluctuations of the float 35 are suppressed. Thus, the reed switch 33 which operates following up the float is prevented from hunting.

Title: Tip for co2 gas shielded arc welding
Inventor: UTSUNOMIYA TAKAMASA
IPC: B23K9/26
Filed: 1982-03-26
Abstract: PURPOSE:To prevent sticking of spatter on a titled tip during welding and to enable the long-term use thereof, by applying a covering layer consisting of an insulating material on the outside surface of a tip body. CONSTITUTION:A covering layer 5 consisting of an insulating material such as a plastic or the like is provided on the outside surface of a tip body 1.

Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a lamination shaping method by which it is possible to contribute to shortening a laser beam irradiation time while securely maintaining the accuracy of a contour of the surface layer part of a shaped object and improve productivity advantageously. SOLUTION: A set layer 10 is formed by lasing a material which is set by irradiation with the laser beam and this formed set layer 10 is laminated to form a three-dimensionally shaped object. In addition, the appropriate diameter of the laser beam is selected out of the different diameters depending upon a part forming the surface layer part of the three-dimensionally shaped object and a part forming the inner part of the three-dimensionally shaped object. That is, the laser beam M1 of a large diameter irradiates the part forming the inner part and the laser beam M2 of a small diameter irradiates the part forming the surface layer part.

Abstract: PURPOSE:To improve the stability of characteristics and reliability and to improve a yield rate by arranging a plurality of coil positioning projections which are in contact with the edge of a coil, and performing injection molding of magnetic resin under the state wherein the coil is set at the specified position. CONSTITUTION:A coil 2 is arranged at a specified position in an injecting metal mold 11, i.e., a cavity 12 for a magnetic resin mold 1, e.g. on the axial center of the cavity 12. The coil 2 is supported with coil positioning projections 13 which are brought into contact with a plurality of places of the edge of the coil 2. Therefore, even if slightly unbalanced pressure is applied to each part of the coil when the injection of magnetic resin into the cavity 12 of the metal mold is started, the coil 2 is supported with the projections which are arranged at the approximately equal angular interval with respect to the axial center of the coil. Therefore, the deformation and the decentering of the coil 2 can be effectively avoided. The peeling of an insulating film due to the abrasion between the coil wire elements by the unbalanced pressure can be further avoided. Thus, the yield rate is improved, the characteristics are stabilized and made uniform and the reliability is improved. The following constitution can be further provided: the projections 13 are brought into contact with the edge 2a, and the coil 2 is pushed to one end of the cavity 12, e.g. to the bottom surface.

Title: Capacity control device for screw compressor
Inventor: YAMAGUCHI NORIHIDE
IPC: F04C18/16
Filed: 1994-03-18
Abstract: PURPOSE:To ensure a proper control speed in a wide operation range where a differential pressure between high and low pressures is fluctuated and to provide a proper load up speed regardless of a cooling water temperature during starting. CONSTITUTION:When a differential pressure between high and low pressures is low during load up, only an on-off valve SV2 on the low resistance side is opened, and oil is discharged through a first discharge passage 8a on the load up side. When the level differential pressure is high, only an on-off valve SV3 on the high resistance side is opened and oil is discharged through a second discharge passage 8b on the load up side. This constitution improves drainage of oil from a chamber 51 on the load side when the differential pressure is low, prevents the occurrence of defective operation of load up and a delay of load up, and prevents a load up speed from being excessively increased when the differential pressure is high.

Title: Buffer memory control system
Inventor: OONO NAOYA
IPC: G06F13/00
Filed: 1982-03-26
Abstract: PURPOSE:To speed up access, by making access to a main storage directly without storing a buffer memory when the locality of access to a segment of each program is low, and preserving the contents of the buffer memory. CONSTITUTION:When a request for access to a memory is generated, the logical address (i, j, k, l) of a request address is stored in an address register 1. An address conversion control circuit 4 retrieves an address converting buffer by using a logical page address (i, j) as a key and obtains buffer control information. An access control circuit 10 checks on the buffer control information and when the disuse of the buffer memory is specified, access to the main storage is attained by an actual address (n, k, l) without making access to the buffer memory. Thus, the hit rate of the buffer memory is increased to speed up the access.
