Title: Hologram transfer foil
Inventor: HOSHINO KAZUHISA
IPC: G03H1/18
Filed: 1991-07-05
Abstract: PURPOSE:To provide the hologram transfer foil which can partially form regions having no hologram images on the surface of a body to be transferred. CONSTITUTION:This hologram transfer foil is constituted by peelably laminating a transfer layer 20 consisting of a release layer 21, a high softening point resin layer 22, a low softening point resin layer 23, a light reflecting metallic thin film 24, and an adhesive layer 25 which are successively laminated, on one surface of a base film 10. The surface of the low softening point resin layer and the surface of the high softening point resin layer of the part where this low softening point resin layer does not exist constitutes the relief type hologram. The low softening point resin layer is softened and deformed by the heat or the heat and pressure at the time of or after transfer and the ruggedness on the surface thereof is annihilated; in addition, many very small and irregular cracks are generated in the light reflecting thin metallic film. The incident light which reproduces the hologram and forms observable virtual images is irregularly and randomly reflected in the cracked parts of this light reflecting metallic thin film. The irregularly reflected light does not only image in the virtual image positions but also becomes white light and does not allow dazzling to be felt.

Title: Wafer polishing method, and dressing method for wafer polishing pad
Inventor: HASHIMOTO SHIN
IPC: B24B37/10
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To avoid deterioration in flatness of a wafer resulting from local deterioration in polishing rate of a wafer polishing pad. SOLUTION: A wafer polishing method uses the lowest common multiple of mn made as large as possible, where (m) and (n) are natural numbers which are relatively prime to each other and representing the revolution per minute (rpm) of a platen mounted with a wafer polishing pad and that of a carrier mounted with a wafer. In such setting, until the platen revolves by the number of (m), the trajectory of a point on the pad brought into contact with a fixed point on the wafer never returns to the contact point at the polishing start and thus distributes uniformly on the pad, which allows any point on the wafer to contact the most region of the pad. This constitution thus avoids deterioration in flatness of the wafer resulting from the frequent contact of some points on the wafer with the pad region having a lower polishing rate as well as the infrequent contact of the other points on the wafer with this lower polishing rate region.

Title: Panel-type radiator for electric apparatus
Inventor: HATTORI MASASHI
IPC: H01F27/12
Filed: 1987-07-03
Abstract: PURPOSE:To surely prevent a peripheral edge part of a radiation panel from being corroded and to enhance the reliablity by a method wherein a material whose ionization tendency is larger than that of a thin iron sheet is attached to a jointed part at the peripheral edge part of the radiation panel and a painted sheet is pasted on an external periphery. CONSTITUTION:A material 16 whose ionization tendency is larger than that of thin iron sheets 5 is, e.g., a sheet of zinc foil or the like; this material is attached to a jointed part at a peripheral edge part of a radiation panel 10, especially to a part outside a seam-welded part 6 which has been a gap part in a conventional system. The material 16 which has been attached to the jointed part at the peripheral edge part of the radiation panel 10 and whose ionization tendency is large prevents moisture, salt or the like from penetrating there to the utmost. Even it the moisture or the like should penetrate, the material 16 whose ionization tendency is large is corroded, and it is possible to prevent the thin iron sheets 5 from being corroded. A corrosion- preventive film with a required thickness is formed at sharp edge parts 15 by using a painted sheet 17 which has been pasted on their external periphery. By this setup, it is possible to surely prevent the peripheral edge part of the radiation panel 10 from being corroded; the reliability can be enhanced.

IPC: G11B7/095
Filed: 1992-06-02
Abstract: PURPOSE:To heighten reliability for a focus setting operation. CONSTITUTION:This device is equipped with a convergence lens 3 to converge projection light on an optical disk 1, an optical detector 4 to receive reflected light, a lens driving part 8 to drive so as to perform the connection/ disconnection of the convergence lens 3 with the optical disk 1, a CPU 11 to control the lens driving part 8 by a sum signal SS and a differential signal DS from the optical detector 4, and a D/A converter 10 to generate a triangular wave current to be supplied to the lens driving part 8 when the focus setting operation is performed. The initial value of the sum signal SS when the convergence lens 3 most approaches the optical disk 1 in the focusing setting operation is detected, and such correction that the position of the convergence lens 3 can be kept constant by that value in the focus setting operation is performed.

Title: Semiconductor light emitting device
Inventor: IMAI HAJIME
IPC: H01S5/227
Filed: 1982-09-22
Abstract: PURPOSE:To reduce the temperature dependency of an oscillating threshold current of a semiconductor light emitting device and to improve the effectiveness of an active layer for narrowing the current by composing the device via a P type semiconductor layer before electrons are implanted from an N type clad layer to an active layer. CONSTITUTION:The first semiconductor layer 14 of the second conductive type having a band gap smaller than the layer 13 arranged on the first clad layer 13 of the first conductive type, the second layer 15 of the first conductive type arranged on the layer 14, a striped groove of the depth reaching the layer 14 formed in the layer 15, an active layer 16 having a band gap smaller than the layer 14 arranged in the groove, and the second clad layer 17 having a band gap larger than the layer 16 arranged on the layer 16 are formed. Thus, electrons in the layer 13 are temporarily implanted to the layer 14 to be lowered at the energy level, and then implanted to the layer 16. Accordingly, electron distribution in the layer 16 approaches the equilibrated state. In this manner, the probability of escaping the electrons to the layer 17 can be reduced, thereby improving the temperature dependency.

Title: Image pickup device
Inventor: SUZUKI MASAO
IPC: H04N5/347
Filed: 1995-06-30
Abstract: PURPOSE: To improve the transfer efficiency of a charge in a vertical transfer section of a CCD in a frame mode while keeping a broad dynamic range and high image quality. CONSTITUTION: For a period (t3 -t6 ) when a charge transfer pulse V3 reaches a high potential VH at first in the frame mode, a potential Vsub , if a semiconductor substrate and a transfer potential VM of charge transfer pulses V1 -V4 are increased to a level 1 from a level 2 in the field mode. Thus, the same transfer efficiency as the field mode is obtained. Moreover, since the charge leaked to the vertical transfer section from the picture element is not transferred, deterioration in the image quality due to blooming is avoided.

Title: Oxygen probe
Inventor: NAKAMURA HAJIME
IPC: G01N33/20
Filed: 1984-08-08
Abstract: PURPOSE:To shorten response time, by specifying the amount of a reference electrode material, which is filled in zirconia solid electrolyte, to be less than a specified value. CONSTITUTION:One-end-closed type solid electrolyte tube 4 of ZrO2-MgO is filled with a reference electrode material 6 comprising mixed powder of Cr/Cr2O3. The filling amount of the reference electrode material 6 is made to be 10mg or more and 60mg or less. The reason why the minimum filling amount of the reference electrode material 6 is made to be 10mg or more is as follows: when the amount is less than 10mg, it is difficult to fill the reference electrode material so as to contact with an Mo lead wire 8 and the inner wall of a tip part of solid electrolyte at the time of filling the reference electrode material; holding of a battery system becomes uncertain; and it is difficult to keep the oxygen potential in the reference electrode constant. The reason why the maximum filling amount is made to be 60mg is as follows: when the amount exceeds this value, the volume of the reference electrode becomes large, long time is required for increasing the temperature; and the improving effect of response cannot be expected.
