Title: Light wavelength conversion element
Inventor: YAMAMOTO KAZUHISA
IPC: G02F2/02

Abstract: PURPOSE:To obtain an element joined with a semiconductor laser in one body by forming the first selection mirror for reflecting fundamental wave and transmitting converted wave on the first terminal face of a light guide formed in a nonlinear optical crystal, and providing the second terminal face with the second selection mirror. CONSTITUTION:A light guide 4' is formed in a nonlinear optical crystal 3' of LiTaO3, LiNbO3, or the like by ion exchange of Ti or its ion injection. A multilayered film 7 of Ge-MgF2-TiO2 is vapor deposited on the terminal face of the light guide 4' on the side of a semiconductor laser 1 to form a mirror for transmitting the fundamental wave of laser beams and reflecting the converted wave having half wavelength of that of the laser beams. A multilayered film of Al-Ge-SiO2 is vapor deposited on the other terminal face 6 to form a mirror for reflecting the fundamental wave and transmitting the converted wave. The beams emitted from the laser 1 is condensed with a lens 2, falls on the light guide 4', and when phase alignment conditions are satisfied by adjusting temp., the converted wave is emitted from the other face 6 with high conversion efficiency. As a result, although the light guide is short, a conversion efficiency about four times that of the conventional element by substantially doubling the conversion distance.

Title: Power eject device
Inventor: SEKI KAKUJI
IPC: G11B15/675
Filed: 1990-08-23
Abstract: PURPOSE:To secure the excellent operability by operating an initial driving means by an operation of an eject lever, transferring the torque of a driving motor to a clutch plate and a swing arm, and allowing an inversion spring and a pack stopper to execute an eject operation. CONSTITUTION:By an operation of an eject lever 1, an initial driving means 4 is operated and the torque of a driving motor 34 is transmitted to a cam plate 20. Therefore, the cam plate 20 executes intermittent driving, and a clutch plate 6 is interlocked therewith. Accordingly, a swing arm 10 engaged to the clutch plate 6 oscillates, and an inversion spring 16 moves against elastic force of the inversion spring 16. Subsequently, when the inversion spring 16 reaches an inversion position, its elastic force works in the direction for discharging a cassette pack, and the cassette pack can be ejected. In such a way, pressing force at the time of operating the eject lever can be curtailed remarkably, and even if the eject lever is miniaturized, there is no fear that the operability deteriorates.

Title: Method for processing silver halide photographic sensitive material
Inventor: FUJITA YOSHIHIRO
IPC: G03C7/30
Filed: 1986-09-18
Abstract: PURPOSE:To prevent generation of bacteria or fungi in a water-washing tank, even in case of reducing an amount of the washing water by effecting a solid- liquid contact or a liquid-liquid contact a processing solution used in a water- washing step and/or a stabilizing step with a bactericide or a fungicide which is sightly soluble in water, at the time of processing the silver halide photographic sensitive material after exposing it. CONSTITUTION:In the water-washing step, etc., which is one of steps of processing the titled material, the residence time of water in the water-washing tank increases, when an amount of the used water is merely reduced, thereby propagating the bacteria in the water-washing tank resulted in generating a muddiness and a suspended solid therein. Thus, the exposed silver halide photographic sensitive material is processed by effecting the solid-liquid contact or the liquid-liquid contact the processing solution used in the water washing step and/or the stabilizing step with the bactericide or the fungicide which is slightly soluble in water, thereby preventing effectively the generation of the bacteria and fungi in the water-washing and stabilizing tank, also giving no adverse effect to the titled material which is exposed.

Title: Generator of fuel cell
Inventor: TOKUNO MASATOSHI
IPC: H01M8/06
Filed: 1988-09-02
Abstract: PURPOSE:To shorten the time between the interruption of operation and the restart by adding a heating means for insulating purpose in the insulating layer of a reformer. CONSTITUTION:The double layer of a primary insulator 2 and a secondary insulator 3 is placed in the enclosure of a reformer. A heating means for example, an electric heater 4 is embedded between the insulators. The electric heater 4 is being disconnected to a power supply during operation, however, after the reformer is interrupted, the power supply is connected to the electric heater 4 via a terminal box 5 so that the electric heater 4 is increased to the high temperature. Since the thermal difference between the inside of the reformer and the electric heater is reduced, the accumulated heat inside the reformer will not escape outside and therefore the radiation from the enclosure 1 means that from the electric heater 4. Thus the temperature of catalyst inside the reformer may be kept high and the time until the heat is increased enough for restarting be shortened so that the restarting may be effected within a shorter time.

Filed: 1999-08-03
Abstract: PROBLEM TO BE SOLVED: To provide an image display device in which an image with higher definition can be displayed in an easily visible state with a limited number of pixels. SOLUTION: The display device is equipped with an LCD having a plurality of pixels which are two-dimensionally arranged, a digital image processing circuit 7a which controls the LCD through each pixel to display the image based on the video signal, a wobbling optical element, a masking circuit 7b, and a control signal generating circuit. The wobbling optical element consists of a liquid crystal cell and a birefringent plate, and the element sequentially refracts the optical path of rays emitted from LCD to shift pixels. The masking circuit 7b masks the lateral ends of the image and displays a black color in this region where the apparent pixel density decreases because the pixels are shifted more than the pitch of the pixels when the pixels are shifted by the wobbling optical element.  The control signal generating circuit is housed in the masking circuit and judges the pixels to be masked on the basis of a start signal, vertical synchronizing signal, a horizontal synchronizing signal, a clock or the like.

Filed: 1993-08-12
Abstract: PURPOSE:To enhance the cooling efficiency of a filament by allowing a filament to be cooled, to run through a virtually enclosed casing and atomizing and vaporizing an inactive and proper low boiling point liquid near the filament in the casing. CONSTITUTION:A place in which a filament 1 runs is partially segmented in an enclosed state, thereby forming a casing 6. On the other hand, the outer ends of a high pressure resistant liquid transfer pipe, which is communicated with and extended into a high pressure vessel 2, are branched into a plurality where a pressure reducing valve 4 is installed to each of the branched parts. At the tip there is mounted each of spray nozzles 5. The spray nozzles 5 are laid out in such a manner that they may be opened near the filament 1 in the casing 6. A finely foggy low boiling point liquid 7 is sprayed to the filament 1 from the spray nozzles 5. Since the heat of vaporization is rapidly robbed of the filament and its near area when the liquid 7 is vaporized, this constitution makes it possible to cool every kind of filament effectively.
