IPC: B22C1/00
Filed: 1992-11-25
Abstract: PURPOSE:To enable casting of a this sheet having good surface characteristic with high quality and high yield by using a graphite-made mold and executing casting in the condition of reducing the pressure, at the time of manufacturing the metal thin sheet by casting method. CONSTITUTION:At the time of casting the metal thin sheet, by using the graphite-made mold 2, the casting is executed in the condition of reduced pressure at the casting temp. of >=1000 deg.C. As the graphite-made mold has large thermal conductivity, the surface characteristic is improved. Burning phenomenon is avoided and crack is not developed. As the graphite has small coefficient of thermal expension, the mold deformation caused by the heat is small and the deformation of cast block is restrained to be small and the dimensional precision is improved. Because of the casting in the reduced pressure, the generation of blow holes is reduced, and as the mold deformation is small, the thickness difference of the sheet is difficult to develop and micro porocity is reduced. By this method, a target material for forming the thin sheet without various defects of crack, etc., can be manufactured at a low cost and with high quality.

Title: Magnetic head for magneto-optical overwrite recording
Inventor: IZUMI HARUHIKO
IPC: G11B5/02
Filed: 1987-12-15
Abstract: PURPOSE:To improve high-speed parity by small inductance and to sharpen magnetic field distribution by coiling a wire around the core of a superconductive body having a groove and realizing a solenoid coil having a small sectional area. CONSTITUTION:A coil 12 is provided for a core 10 which is a square pole made of the superconductive body and to which a groove 11 whose sectional area is rectangular is provided in its longitudinal direction. The coil 12 is fitted to the end part of a floating slider 13 so that the longitudinal direction of the section of the groove 11 may face in the radius direction of a disk. Then, currents to flow in the coil 12 and the core 10 are in opposite directions, therefore, the groove becomes a solenoid and a magnetic field generated by a coil 12 is canceled except the groove 11. As the result, even when the inductance is made small, magnetic field intensity does not weaken and the high parity is improved. When the groove part 11 is arranged like mentioned above, even when a light spot moves in the radius direction because of the eccentricity of the disk, the groove part 11 does not get out of the light spot and therefore, the magnetic field distribution becomes sharp in the groove part 11.

Title: Hydraulic power steering system
Inventor: TASHIRO MORIKI
IPC: B62D5/07
Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To allow the hydraulic pressure to be relieved when the pressure in a reaction force chamber rises by providing a relief valve that opens when the pressure in the reaction force chamber is equal to or greater than a predetermined value in a linking oil passage between the reaction force chamber that introduces a high pressure oil to a plunger and a low pressure chamber that introduces a low pressure oil, so as to prohibit an increase in steering effort. SOLUTION: When a pressure oil discharged by a hydraulic pump, the flow rate of which is controlled to a predetermined value, is supplied to an inlet port 11 of a gear box portion, it is supplied to a high pressure chamber 82 between a valve housing 10 and a pinion shaft 40 through a solenoid valve. The pressure oil pressurizes the other end surface of a reaction force plunger 72, thus a projection of a valve shaft 20 is sandwiched by projections on both sides. This makes a relative rotation between a valve body 30 and a valve shaft 20 less likely to occur and reduces an assist force generated in the steering system. A relief valve 75 incorporated in a bolt 74 for preventing a reaction plunger from slipping relieves increased pressure in the high pressure chamber 82 to the low pressure chamber 80.  This enables control of steering effort with a large operation angle of a steering wheel.
