Title: Manufacture of r-fe-b anisotropic compression-molded bonded magnet
Inventor: MURAMATSU RYOJI
IPC: H01F1/057
Filed: 1990-06-05
Abstract: PURPOSE:To improve the magnetic property of the title magnet, such as the packing ratio, degree of magnetic orientation, etc., of magnetic powder by performing the first compression molding on a mixture of R-Fe-B anisotropic magnetic powder and a binder under a low pressure in the direction perpendicular to a magnetic field impressing direction, and then, the second compressionmolding on the mixture with a pressure lower than the first pressure in the direction parallel to the magnetic field impressing direction. CONSTITUTION:The first compression-molded body is formed by performing the first compression-molding on a mixture of R-Fe-B anisotropic magnetic powder prepared by pulverizing thin bands obtained by quenching an R-Fe-B (R: a rare earth element containing Y) liquid and a binder after hot upsetting under a low pressure in the direction perpendicular to a magnetic field impressing direction. Then the second compression-molding is performed on the mixture with a pressure lower than the pressure of the first compression-molding in the direction parallel to the magnetic field impressing direction. As a result, an R-Fe-B anisotropic compression-molded magnet with anisotropic magnetic powder which is high in degree of magnetic orientation and packing ratio can be obtained. The second compression- molding can be performed while the magnetic field is applied in the same direction as the magnetic field applied direction and it is preferable to set the pressure of the first compression- molding at 0-3 tons/cm<2> (however, '0' is not contained).

Title: Optical recording and reproducing device
Inventor: YANAGIDA TSUNEO
IPC: G11B7/24
Filed: 1982-08-25
Abstract: PURPOSE:To obtain a portable optical recording/reproducing device having a compact and light-weight structure, by forming a light generating substrate serving as an optical spacer and a lubricant layer on the recording surface of a recording medium and pressure-fixing an objective lens to the lubricant layer to focus the laser light. CONSTITUTION:When a disk 50 is revolved by a disk driving motor 31, an objective lens 66 slides with a pressure contact on a transparent substrate 50B via a lubricant layer 50A. Thus a fixed sitance is always secured between the lens 66 and a record layer 50C. This can eliminate a focusing error owing to the wrap or recessing/projecting parts of the disk 50. Furthermore a cylindrical lens 63 is put between a collimator lens 62 and a polarized beam splitter 64 in a reproduction mode. As a result, the laser light condensed to the layer 50C is changed to an oval beam to track a pit. Thus the allowance value is increased to a tracking error.

Abstract: PURPOSE: To reduce the discharge gas in the whole body of a vacuum vessel, by generating a specific electromagnetic field in the vacuum vessel, so that a synchrotron radiating light is radiated concentratively to a beam damper where the gas radiation is little. CONSTITUTION: The charged particles 14 are deflected along a specific peripheral track in a vacuum vessel 11 and run by the electromagnetic field formed by a pair of deflection electromagnets 17 provided up and down in the vacuum tub 11, and at the same time, they produces an SOR light 18 in the tangent direction of the peripheral track. This SOR light 18 advances straightly in the vacuum vessel 11, and strikes concentratively to a beam damper 20 fixed and arranged along the inner wall 19 at the side surface of the second space 15. This beam damper 20 is formed of a material with little gas discharge, fixed through an insulating substance, and biased to the positive potential by a bias power source. The optical electrons 23 generated by the SOR light 18 are absorbed there.  In such a way, the beam damper 20 can be formed of a material with little gas discharge, regardless of the material of the vacuum vessel 11, and the discharge gas in the whole body of the vacuum vessel 11 can be reduced.
