Title: Oil pressure actuator
Inventor: MAEDA HIROAKI
IPC: F15B9/09
Filed: 1982-09-29
Abstract: PURPOSE:To obtain a compact and inexpensive oil pressure actuator by selecting a differential type oil pressure cylinder and using a couple of small and inexpensive on-off valves. CONSTITUTION:When 10 is set by a displacement indicator 17 and a displacement detector 14 is displaced to 3, since the plus side of a comparator 16 is larger by 7, the electric current flows to a reed relay 20 to operate the first solenoid valve 9. Therefore, the oil of an oil pressure source 7 flows into the second chamber 6 to move a piston 4 towards right side. When the displacement detector 14 is displaced to the position 10, the comparator becomes plus minus 0 and no signal is emitted, which stops the operation f the reed relay 20 to close the first solenoid valve 9 and stop the piston 4 at that position. If the displacement indicator 17 is set at 3, the right side of an inverter 22 becomes plus and the current flows to a reed relay 21 to operate the second solenoid valve 11. The piston 4 moves toward left, and when the lever 14a is displaced to 3 of the displacement detector 14, it stops at that position.

Filed: 1990-06-29
Abstract: PURPOSE:To enable the magneto-optical recording at a high density and high speed transfer rate by diminishing an area of such a part in a magneto-optical recording medium that its temp. is to be more than the Curie temp. CONSTITUTION:A light spot in a recording part position of a prependicular magnetization film 3 to be formed by a laser beam SHG passing through a dichroic mirror and a light spot in a recording part position of the prependicular magnetization film 3 to be formed by a laser beam LD reflected by the dichroic mirror 13 are matched in position so as to be coincident in both the radial direction and the track direction of an optical disk 1.

Title: Magnetic recorder and its manufacture
Inventor: ECHIGO NORIYASU
IPC: G11B15/61
Filed: 1988-07-11
Abstract: PURPOSE:To reduce the coefficient of friction between the surface of a member which is brought into contact with a magnetic recording medium and the medium and, at the same time, to divide a water layer formed on the surface of the medium so as to suppress sticking of the member to the medium by providing bores having a specific mean diameter in the surface of the member. CONSTITUTION:A highly pure Al film 2 is formed on an Mn-Al base material 1 and regular hexagonal cells of Al2O3 3 are formed on the surface of the Al film by performing alkali etching and anodic oxidation. Then the mean diameter of bores 4 is enlarged to 500-10nm by performing electrysis on the anodically oxidized film with 1% phosphoric acid solution. The bores 4 thus enlarged are then filled up with paraffin which is soluble to an organic solvent. After filling up the bores 4, a tape guide is produced by grinding the surface smoothly to a desired shape and dissolving the paraffin by the solvent. Thus the coefficient of friction between the tape guide and a magnetic tape can be reduced and, even when a water layer is formed on the surface of the tape, sticking of the tape guide to the magnetic tape can be prevented because the guide can divide the water layer.

Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To stabilize the running resistance of the drum section of a magnetic recording and reproducing device using an upper drum-fixed type rotary head/ drum assembly by vibrating the upper drum of the assembly at a high frequency. SOLUTION: The upper end of a drum support 21 is connected to a drum holder 25 in a finely movable state with drum support coupling screws and, at the same time, the projection 27 of the upper end is connected to the holder 25 through a high-frequency vibration generating member 23. Thus, a lower drum 5 is connected to an upper drum 3 through the member 23 in a finely movable state. The fine high-frequency vibration of the member 23 is transmitted to the upper drum 23 through the drum holder 25 and finely vibrates the drum 3 at a high frequency. Since air is caught between the upper drum 3 and a magnetic tape 10, the substantial frictional resistance at the boundary between the drum 3 and tape 10 is reduced. In addition, an additional amount of air is caught due to the vibration transmitted to the tape 10, the frictional resistance is further reduced.
