Title: Optical disc with protective film and its production
Inventor: SHIBATA ITARU
IPC: G11B7/24
Filed: 1984-08-31
Abstract: PURPOSE:To enhance the adhesive strength of a protective film to improve the durability by forming a metallic recording medium layer on a substrate and oxidizing the surface of this layer and coating the recording medium layer with a metal whose bonding strength to oxygen is higher than that of the metal of this layer and subjected the coating metal to heat treatment to form a metal oxide protective film. CONSTITUTION:A recording medium layer 2 consisting of a metal such as Te, TeOx, Te-C, or the like or a semimetal is formed on a substrate 1 consisting of glass, plastics, or the like, and the surface of the layer 2 is heated, for example, in a humid atmosphere to form an oxide area 3. A metallic thin film consisting of Ti, Si, Cr, or the like whose bonding strength to oxygen is higher than that of the metal of the layer 2 is formed on the area 3 by vapor-deposition or the like. This thin film 4 is subjected to heat treatment at about 70 deg.C for about 24hr. Thus, oxygen from the area 3 is migrated to the film 4 to form a protective film 5 consisting of a metal oxide. The internal stress of the film 5 is relaxed considerably in comparison with a directly vapor-deposited oxide, and the adhesive strength to the recording layer is high, and cracks or the like do not occur, and thus, an optical disc superior in durability is obtained.

Title: Horizontal type hydraulic hoist
Inventor: SAITO MAKOTO
IPC: B65G53/30
Filed: 1985-08-21
Abstract: PURPOSE:To aim at the prevention of wear in a slurry pressure-feed selector valve, by installing a photo-sensor, detecting a flow of slurry, at the inlet side of this valve, and controlling a slurry pump discharge. CONSTITUTION:A transparent plug 11 is installed in a position distant from a slurry pressure-feed selector valve 2a to the side of a feed pipe 7a, and a photo-sensor is constituted of a light emitting body 12 and a light receiving body 13. In the state that slurry is fed to the inside of the feed pipe 7a, if a driving fluid is fed to the feed pip from a driving fluid pump 8, the slurry is fed, with pressure, to a transport pipe 9 by way of the valve 2a. At this time, if the valve 2a is closed before a slurry rear part passes through the valve 2a, it is remarkably worn out. In this case, since slurry length inside the feed pipe means a quantity of the slurry to be fed to the feed pipe 7a from a slurry pump 6, time of up to each close signal of the light receiving body 12 and the valve 2a is counted in order to control this feed quantity, comparing it with the preset time, and when this preset time is longer than that, a discharge of the slurry pump 6 is reduced. With this constitution, when the pressure-feed selector valve is closed, it is always carried out in the driving fluid so that wear in the valve comes to nothing.

Title: Film-thickness measuring apparatus
Inventor: KOKUBO MASAHIKO
IPC: G01B11/06
Filed: 1995-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a film-thickness measuring apparatus by which the film thickness of a thin film on a substrate can be measured with good reproducibility irrespective of the inclination of a sample face tb be measured. SOLUTION: An illumination optical system 20 is provided with a glass rod GL which compensates the wavelength dependence on the luminance distribution of light sources HL, DL. When a sample SP to be measured is tilted and the shading of reflected light is generated, the energy of the reflected light is reduced. Even in this case, the distribution state of the spectrum of the reflected light which is incident on a spectral unit 40 is almost maintained. Consequently, in a control unit 50, the ratio of the mean value of a working- curve relative reflectance to the mean value of an actually measured relative reflectance decided on the basis of the output of the spectral unit 40 is converted into data by which the actually measured relative reflectance is multiplied, and the deviation between both is then found.  Thereby, it is possible to prevent the influence of the inclination of the sample SP to be measured, and a film thickness can be measured precisely.
