Title: Optical disk restoring device
Inventor: SOEEDA YOSHINOBU
IPC: G11B23/50
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To shorten a working time by making the surface of an optical disk to be in a viscous liquid state while heating it and restoring scratches while deforming the surface of the disk to a mirror face to make the restoration a simple one. SOLUTION: After the temp. of the surface of an optical disk 1 is heated to a fixed temp. by the heater and the temp. sensor incorporated in a thermal head 4 and it is stabilized, heat is transmitted to the surface of the optical disk to bring the surface to a high temp. by pressurizing the thermal head 4 to the surface while driving a contact/separation member 8. Here, when a turntable 2 is revolved by a driving mechanism 3, this state performs the retoring of scractches being on the surface of the optical disk 1 over the whole of peripheries. Then, the surface of the disk 1 is worked to a state near to a mirror face by allowing the thermal head 4 to slide on the surface while making the surface to be in the viscous liquid state and deforming the surface.  Since heights of projecting and recessing scratches being on the surface of the disk 1 are sizes of several microns, the surface of the disk is flattened completely by the working to the mirror face, that is, the scratches are eliminated completely.

Title: Magnetic head and its manufacture
Inventor: HASEGAWA HIROYUKI
IPC: G11B5/187
Filed: 1988-07-25
Abstract: PURPOSE:To manufacture a uniform narrow gap at high yield having a sufficient recording characteristic and an excellent gap length accuracy by directly forming a metallic magnetic body on the gap surface of the half body of a head core with the aid of sputtering or a vapor deposition method. CONSTITUTION:A head magnetic path is constituted by the half body of the head core 1 of a C type consisting of ferrite and the metallic magnetic body 2 of an I type which is directly formed on the gap surface of the half body of the head core 1 with the aid of the sputtering or the vapor deposition method and an operating gap is constituted by a joining layer 3 between the half body of the head core 1 and the metallic magnetic body 2. That means, when the metallic magnetic body 2 is not formed through a specified gap material but directly formed on the gap surface of the half body of the head core 1 by the sputtering or the vapor deposition method, the joining part between the ferrite 1 and the metallic magnetic body 2 performs the same effect as an operating gap in a head in a ring state. Thus, the operating gap for the time when the gap is narrow is easily formed and the uniform narrow gap having the excellent gap length accuracy can be manufactured at high yield.

IPC: F16N7/38
Filed: 1982-10-20
Abstract: PURPOSE:To prevent a siphon phenomenon from generating, by a method wherein a downward liquid flow and an upward liquid flow are checked in intermediate parts of branch pipes. CONSTITUTION:Opening pressures of checking mechanisms 6, 7 of a valve V are respectively set to be not lower than 1kg/cm<2> and not higher than 0.5kg/cm<2>. When the distance from the pipe 2 at a height of 3m to the valve V is 2.5m and the distance from the valve V to the distributing valve is 0.5m, the checking mechanism 6 blocks the downward liquid flow by a closing torque of about 0.7kg/cm<2> (1-0.25-0.05) when the pump is stopped. When a cause of leakage of the liquid is generated at a lower part of a pumping-up (main) pipe, the negative pressure exerted on the back flow is considered to be not higher than -0.1kg/cm<2>, so that when the negative pressure (siphon suction) exerted on the checking mechanism 7 is 0.1kg/cm<2>, the upward liquid flow is blocked by a closing torque of 0.4kg/cm<2> (0.5-0.1), whereby air is prevented from being sucked into the piping system.
