Filed: 1989-01-25
Abstract: PURPOSE:To prevent reaction between water, carbon dioxide gas, corrosive gas, etc. and Na2O of an anode layer, improving reliability by a method wherein the anode layer or a surface of an ion conductive ceramic plate including the anode layer is coated with a gas insulation layer. CONSTITUTION:An anode layer 12b formed on one end of a sodium ion conductor in a thin plate (NAXS plate) 11 and a surface of the NAXS plate 11 other than a cathode layer 12a are coated with a gas insulation layer 14 made of an amorphous glass layer.

Inventor: MORIMURA NOBORU
IPC: G11B19/20
Filed: 1989-01-25
Abstract: PURPOSE:To simplify the loading action of a magnetic disk and at the same time to prevent the eccentricity of a rotary system by writing a head positioning servo signal onto at least one of both sides of the disk, then reading out the servo signal for execution of control and a head positioning action. CONSTITUTION:A disk 9 has a hole at its center to hold a spindle motor hub 1 and forms a hole shape where a head is positioned through an approximately cylindrical surface of the hub 1 and three areas. The inner circumference of the disk 9 forms an approximately triangular shape which defines a flexible part 8 as one side. Thus the projecting parts of the triangle are bent and the head is loded fixedly via these three bent areas. At the same time, a head positioning servo signal is written onto at least one of both sides and then read out of control and to position a head. Then the hub 1 is loaded to the disk 9. Thus the hub 1 is positioned together with generation of the pilot pressure and attached easily. Furthermore no excentricity is produced when the inner circumferential surface is decided so as to secure the coincidence between the centroid of the disk 9 and the rotational center of the hub 1 in a loaded state of the disk 9.

Title: Scroll compressor
Inventor: SAWAI KIYOSHI
IPC: F04C18/02
Filed: 1985-01-30
Abstract: PURPOSE:To prevent over-compression of compression chamber by constructing such that the start-of-winding angle of fixed scroll is higher than the lap of a swivel scroll thereby enlarging the flow path from a compression chamber surrounded by the outer wall of fixed scroll and the inner wall of swivel scroll to a delivery hole. CONSTITUTION:With respect to an involute curve constituting the outer wall 21 of fixed scroll, the start-of-winding angle is made larger when compared with the involute curve constituting the outer wall 22 of swivel scroll lap. Consequently, at the time point when the compression chamber 16A has finished compression (at the time point when contacting with the lap 23), the start-of- winding section 19 has already been separated from the counter part lap inner wall 24 and forming the delivery path of compression chamber 16B. Upon transfer of the compression chamber 16A side into delivery process, high pressure gas is delivered quickly through a delivery hole 13. At the same time, large flow path is ensured between the compression chamber 16B to the delivery hole 13 to reduce over-compression in the compression chamber 16B thus to improve the compressor efficiency.

Title: Apparatus for improving restarting performance of supercharged engine
Inventor: HASEGAWA KUNIO
IPC: F02B37/16
Filed: 1983-02-03
Abstract: PURPOSE:To improve the restarting performance of an engine, preventing supply of over-rich mixture to a combustion chamber by introducing air into an intake passage at the time of starting the engine. CONSTITUTION:At the time of cranking for starting an engine, pressure at a portion 25 located on the downstream side of a throttle valve is higher than a prescribed negative pressure (for instance, -150mm.Hg), so that a vacuum-operated diaphragm means 22 is not set into operation. On the other hand, since pressure at a portion 19 located on the upstream side of the throttle valve is lower than a prescribed positive pressure (for instance, 50mm.Hg), a positive-pressure operated type diaphragm means 16 is not also set into operation. In this stage, an air inlet passage 5 is opened. When pressure at the portion 25 on the downstream side of the throttle valve becomes lower than said prescribed negative pressure with increasing of the engine speed, the vacuum-operated diaphragm means 22 is set into operation and the air inlet passage 5 is closed by a swing valve 10. When a supercharger 1 is set into operation with further increasing of the engine speed and pressure at the portion 19 on the upstream side of the throttle valve becomes higher than said prescribed pressure, the positive-pressure operated type diaphragm means 16 is set into operation and the air inlet passage 5 is closed by the swing valve 10.

Title: Insulating composition of power cable
Inventor: TANAKA SHIGENORI
IPC: H01B3/44
Filed: 1990-01-26
Abstract: PURPOSE:To improve the water tree-resistant characteristic of the insulating composition of a power cable without causing any lowering of the electric characteristic and any deterioration in the extrudability by compounding 0.1 to 5 pts.wt. of dihydroxydiphenyl sulfone derivative with 100 pts.wt. of polyolefine. CONSTITUTION:The insulating composition of a power cable has 0.1 to 5 pts.wt. of a dihydroxydiphenyl sulfone derivative(DHOPS) added to 100 pts.wt. of polyolefine. For the polyolefine in this case is generally used low-density polyethylene among the group of polyethylene, more particularly prepared through the manufacturing process of using no polymerization catalyzer. The DHDPS is accordingly represented by a formula 1 wherein R represents CnH2n. Also when necessary, a cross-linking agent and carbon black, an age resistor, etc., are properly added to the insulating composition. The water tree-resistant characteristic of the insulating composition can thus be improved without damaging each of the insulation resistance, the physical characteristic and the extrudability.
