Title: Magnetic disk excellent in durability
Inventor: HOSOMI KAZUHIRO
IPC: G11B5/84
Filed: 1990-06-20
Abstract: PURPOSE:To improve sliding durability and adsorption resistance by making the lubricant film of a CSS zone thicker than the lubricant film of a data area in a magnetic disk having surface coarseness higher than the surface coarseness of the data area. CONSTITUTION:The surface coarseness of the CSS zone is higher than that of the data area, and the ratio of average lubricant film thickness between the CSS zone and the data area is set within a range from 1:0.1 to 0.8. On the other hand, in the CSS zone enlarging the surface coarseness, the quantity of lubricant is made much and in the data area reducing the surface coarseness, the quantity of lubricant is made a little. As a manufacture, a spin coat method using two nozzles is applied, and solvent and lubricant is dropped down from the first nozzle at the central side of the disk. Only the solvent or the lubricant including much solvent is dropped down from the second nozzle at a boundary between the CSS zone and the data area, and the lubricant from the second nozzle onto the data area at an outer peripheral part is diluted. Then, after vaporizing the solvent, the lubricant is diluted, and the disk can be obtained with the difference of the lubricant film between the CSS zone and the data area.

Title: Bonding tool
Inventor: OKAMOTO JUNICHI
IPC: H01L21/603
Filed: 1987-06-26
Abstract: PURPOSE:To prevent a bonding tool from generating warp, and improve the yiels of bonding, by forming the bonding tool of the same material, and providing the bottom part with a diamond coating film. CONSTITUTION:A bonding tool is formed of the same material. A surface facing a junction part is provided with a diamond coating film 11. The warp of bonding tool generating at the time of bonding wherein a semiconductor element electrode and a film carrier lead are subjected to thermocompression bonding is prevented from generating, because the same material is used and unified in a body, so that the difference of thermal expansion coefficient does not exist. Further, as the film 11 is formed, cracks do not generate at the edge part of the bottom of the bonding tool. Thereby, the yield of bonding can be improved.

Title: Wavelength stabilized laser
Inventor: MATSUI YASUSHI
IPC: H01S5/0687
Filed: 1985-07-19
Abstract: PURPOSE:To make it possible to implement excellent etalon effect and to make it possible to stabilize the wavelength highly accurately, by adopting a lightguide having the cleavage surface of a semiconductor crystal, and making it possible to control the light path length of the lightguide at the same time. CONSTITUTION:A laser 1 and a lightguide 3 are constituted by a semiconductor material. In the lightguide 3, the length of the light path can be controlled by the electrooptic effect of the semiconductor and the temperature control. The light emitted from the lightguide 3 is measured by a light detector 4. At this time, the light output is varied by etalon effect depending on the wavelength. By utilizing the fact that the oscillating wavelength of the laser is proportional to the injected current, control is performed so that the emitted light output from the lightguide becomes constant. For this purpose, a minute current to the laser is controlled through an electric signal feedback device 7. Thus the oscillating wavelength can be stabilized.
