Patent JP-H05243672-A (JP)
Title: Manufacture of semiconductor laser device
Inventor: BAN YUZABURO
IPC: H01S5/00
Filed: 1992-03-02
Abstract: PURPOSE:To obtain a laser element of the shortest wavelength with the same active layer structure, by emitting an electron beam on an active layer and extinguishing a natural superlattice structure. CONSTITUTION:The element structure of an AlGaInP/GaAs visible light semiconductor laser device is fundamentally similar to that of conventional transverse mode control type. The point different from the former one is that an electron beam is emitted on an n-type AlGaInP:Si clad layer 3, a GaInP active layer 4, a p-type AlGaInP:Zn clad layer 5, a p-type GaInP etching element layer 6, a p-type GaInP intermediate layer 7, and a p-type GaAs:Zn cap layer 8. Natural superlattices are in an extinguished state in each crystal. Accordingly, the oscillation wavelength of the laser element becomes the shortest one of those in the case of the GaInP active layer, and the oscillation wavelength does not change with the passage of time. When the electron beam is applied to an resonator end surface, natural superlattice structure in an active layer in the vicinity of the resonator end surface is extinguished, and band gap energy there becomes larger compared to that of the inside, and it becomes possible to realize a high-output type laser.

Title: Hearing aid device
Inventor: UEMURA MASAHIKO
IPC: A61B5/12
Filed: 1981-03-25
Abstract: PURPOSE:To enable to adjust the amplification factor and the dynamic range optimizingly for persons who have a difficulty in hearing at each frequency band, by changing the cut-off frequency and the attenuator of a low pass filter and a high pass filter. CONSTITUTION:A band filter consists of a low pass filter 3 and a high pass filter 4, and a signal amplified at an amplifier 2 is split into three different frequency bands. An attenuator 5 adjusts the amplification factor, a compressor  amplifier 6 compresses the dynamic range, and an attenuator 7 adjusts the upper limit of the dynamic range. A mixer 8 mixes signals split into three zones and they are applied to a earphone 9. Thus, the amplification factor and the dynamic range at each frequency zone can optimizingly be adjusted to a person who has a difficulty in hearing, by changing the cutoff frequency of the low pass filter 3 and the high pass filter 4 and the attenuators 5 and 7.

Abstract: PURPOSE:To provide a luminous ornament which enables a specified pattern to be cubicly luminous and reflected even though the surface of its front cover is made flat in the luminous ornament mounted on the front grill, rear body and the like of an automobile. CONSTITUTION:This luminous ornament is equipped with a transparent resin- made front cover having a flat surface 24, a back face 22 with recessed sections 20, and a light guide 12 fixed on the back face side of the front cover.

When the light guide 12 is made luminous, its irradiating light passes through the semi-transparent light reflecting layer 16 so as to be irradiated outside out of the recessed sections. Meanwhile, outside light passes through the recessed sections, gets to the semi- transparent light reflecting layer 16 so as to be reflected therefrom, and it then passes through the recessed sections again so as to be led outside thereafter.

Title: Inverter device
Inventor: KAWAGUCHI AKIRA
IPC: H02M7/493
Filed: 1994-03-16
Abstract: PURPOSE:To suppress the current dispersion among inverter devices connected in parallel within a fixed value by giving control signal in pulse shape to the integration control of a voltage controller, according to the dispersion of currents among the inverter devices connected in parallel. CONSTITUTION:The output detected by the current detector 6 installed on the output side of an inverter device at large is inputted as a detected current 41 into a gain 43 and is increased 1/n time. The output of the current detector 3a installed on the output side of an inverter 10a is subtracted as a detected current 42 from the detected current 41 being increased 1/n time, so as to seek the deviation. This deviation is converted on the coordinate synchronized with the output voltage by a vector converter 32 so as to get an unbalance current. This unbalance current is proportional to the dispersion of the output current between inverter devices 10a and 10b connected in parallel. Accordingly, by suppressing the unbalance current to a fixed value or under, the dispersion of the output current between the inverters 10a and 10b can be suppressed to a fixed value or under.

Title: Motion vector searching method and device therefor
Inventor: YASHIMA YOSHIYUKI
IPC: H04N19/56
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To detect a correct motion vector even when an arithmetic amount is reduced by setting small a retrieval range of the motion vector when the motion vector is easily estimated from vicinity motion vectors and setting large the retrieval range of the motion vector when the estimate of the motion vector is difficult from vicinity motion vectors. SOLUTION: An evaluation value D(u, v) representing the similarity of a small block deviated by u, v on a reference image with each of 1st small blocks A, B being motion vector detection objects is calculated. The searching is executed within a 1st reaching sange being -Ru<=u<=Ru-Rv<=v<=Rv (wherein, u, v are predetermined). On the other hand, as for 2nd small blocks B, D, the searching is executed within a 2nd searching range around the center of the 1st range deviated by (U1, V1) being U1-R'u<=u<=U1+R'u, V1-R'v<=v<=V1+R' v. The range to be searched in the 2nd small block is smaller than the 1st searching range. Thus, even when the amount of arithmetic operation of motion detection processing is reduced, a correct motion vector is detected.
