Title: Production of hologram
Inventor: FUKAYA NAOKI
IPC: G03H1/02
Filed: 1990-03-23
Abstract: PURPOSE:To produce the hologram which is free from clouding and is uniform over the entire surface with high efficiency and good reproducibility by subjecting a gelatin dichromate film prior to exposing to hardening treatment. CONSTITUTION:Carboxylate having trivalent chromium as a hardener is incorporated into a soln. prepd. by dissolving ammonium dichromate into an aq. gelatin soln. The photosensitive liquid is prepd. in such a manner. The photosensitive liquid is then applied on a glass substrate and is dried to harden the film. The gelatin chromate film is hardened to a prescribed hardness in this stage. This film is exposed by a laser. The exposed dry plate is washed with water and is subjected to the hardening processing by a hardening fixer for photography. The influence of external atmospheres, such as temp. and humidity, and the influence of the fluctuation in exposure are substantially eliminated if this dry plate is hardened to the certain adequate hardness prior to the exposing. The hologram having the good reproducibility is thus obtd.

Title: Spectroscope
Inventor: NANKO TOMOAKI
IPC: G01J3/453
Filed: 1995-03-31
Abstract: PURPOSE: To precisely measure the spectral characteristic of a sample even when the emitted light is uneven by an environmental change on light source side by dividing the output light of an optical fiber and making the resulting lights incident to measuring and reference optical fibers. CONSTITUTION: The interference light from a Michelson interferometer 50 is converged to a part (d), and incident to an optical fiber 19. This interference light is divided into two by a coupler 20, and incident to optical fibers 7, 11 (for measurement and for reference). The spectral characteristic of the measured signal in an optical detector 10 contains the characteristics of a while light source 1 and the optical fibers 19, 7, 9 in addition to a sample 8. On the other hand, the reference signal in an optical detector 12 contains the spectral characteristics of the light source 1 and the optical fibers 19, 11. Since the optical fiber 11 is arranged in the same route as the optical fibers 7, 9, the optical fiber 11 and the optical fibers 7, 9 show the same spectral characteristic.  Thus, the spectral characteristic of the measured signal is divided by the spectral characteristic of the reference signal, whereby the influence of an environmental change can be compensated.

Title: Carrier tape
Inventor: TAKAHASHI TOSHIHARU
IPC: B65D73/02
Filed: 1989-03-29
Abstract: PURPOSE:To prevent the occurrence of rejected outer leads due to the deformation resulting from an accidental shock given to carrier tape by providing a cavity with a relief at each of its corners. CONSTITUTION:Each cavity 7 is provided with a relief 8 at each of the fur corners so as to avoid contact with an outer lead 3 located at each end of the individual rows of the outer leads 3 mounted to a semiconductor 1 received in the cavity 7. Four position limiting parts 9 are so arranged as to project to near the ends of the outer leads 3 at the central part of each row of the outer leads 3, thereby effecting a positional restraint substantially over the semiconductor 1 received in the cavity 7. Even if the semiconductor 1 is made to rotate by the shocks resulting from the dropping of carrier tape, the endmost outer leads 3 of each row are only entered into the reliefs 8 free from contact with the side walls of the cavity 7.

Title: Gas cast injection molding
Inventor: MATSUSHIMA MAKOTO
IPC: B29C45/00
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of shrink of a base of a boss while maintaining a strength of the boss by detouring a gas channel to a periphery of the boss and forming it. SOLUTION: When a position provided with a boss 1 is superposed on a position to be formed with a gas channel 5 of a hollow molding having the boss 1, the boss 1 is detoured and the channel 5 is formed. Thus, a reduction in thickness of the base is avoided, and simultaneously shrink of the base is prevented. In the case of detouring the channel 5, an outer periphery of the boss 1 and an outer periphery of the channel 5 formed by detouring are approached as near as possible in the molding. The shrink might be recessed in a ring state at the base or in a curved state. A detouring circuit of the channel 5 is provided near the boss 1, gas pressure is applied to a periphery where shrink is easily generated to effectively prevent the shrink. Thus, even with the boss 1, a strength of the boss 1 is not lowered, but the occurrence of the shrink of the base can be effectively prevented.

IPC: H01P1/203
Filed: 1991-04-08
Abstract: PURPOSE:To avoid dispersion as the filter and to assemble the filter with a comparatively large tolerance by forming one resonance electrode with a prescribed pattern and forming other resonance electrode with a prescribed pattern of a smaller size. CONSTITUTION:Plural strip resonance conductors 11, 12, 13 acting as the filter are formed to an inner surface directed inward at the assembly of a dielectric board 10. A ground conductor is formed to the surface of other dielectric board 20 and three strip resonance bodies 21, 22, 23 of the same pattern but of different width and length slightly are formed to a position corresponding to the three strip resonance conductors 11, 12, 13 on the inner surface of the one dielectric board 10. Since the three strip resonance conductors 11, 12, 13 are formed smaller than a desired pattern, even when the overlapping of the two dielectric boards 10, 20 is not exactly coincident and deviated more or less, the board 20 is not deviated from a range of the resonance conductor of the desired pattern provided to the one dielectric board 10.

Title: Solid-state relay
Inventor: AKIYAMA SHIGEO
IPC: H03K17/78
Filed: 1989-03-28
Abstract: PURPOSE:To improve the speed of switching by connecting a discharging path by an MOS thyristor between the gate and source of an MOSFET for output and discharging an accumulated charge between the gate and source of the MOSFET for output at high speed. CONSTITUTION:The serial circuit of a resistor 3 and a photo-transistor 4 is connected to the both ends of a photoelectromotive force diode array 2 and the potential of a connecting point is impressed to the gate of an MOS thyristor 5. Then, the MOS thyristor 5 is connected to the both ends of the photoelectromotive force diode array 2. When the optical signal of a light emitting element 1 is lost, the accumulated charge between the gate and source of MOSFET 6a and 6b for output is speedily discharged by the conduction of the MOS thyristor 5. When the optical signal of the light emitting element 1 is generated, the gate potential of the MOS thyristor 5 is held low by the conduction of the phototransistor 4. Accordingly, the switching can be realized at high speed without interrupting the accumulation of the charge between the gate and source of the MOSFET 6a and 6b for output.
