Title: Buried hetero semiconductor laser
Inventor: KITAMURA MITSUHIRO
IPC: H01S5/227
Filed: 1981-10-13
Abstract: PURPOSE:To largely improve the manufacturing yield of a buried hetero semiconductor layer by forming wide mesa stripes of the same height at both sides of a mesa stripe containing an active layer, thereby preventing the mechanical damage occurred at the time of treating the substrate after mesa etching and buried growing time. CONSTITUTION:stripes are formed by photoresist method on a mutilayer film wafer sequentially grown on a (100) N type InP substrate 201, and are deeply mesa etched. A mesa stripe 205 of 2mum wide and 2.5mum high with an InGaAsP active layer 203 to be recombined with emission of light and protecting mesa stripes 206, 207 of 50mum wide isolated by 20mum from the stripe 205 are formed.

Title: Method and device for reconstituting picture having double-magnification function
Inventor: MATSUMURA SHIGERU
IPC: A61B6/03
Filed: 1988-06-30
Abstract: PURPOSE:To compensate frequency deterioration at the time of interpolation and to prevent the deterioration of picture quality by performing a filtering process in a state where data are in a frequency space. CONSTITUTION:A data collector 1 collects data and processor 2 converts the collected data into data in a two-dimensional Fourier plane. A filtering device 3 performs a filtering process on the data in the Fourier plane. Then a picture reconstituting device 4 converts the data in the Fourier plane into picture data by performing picture reconstituting calculation after a 2DFT (two-dimensional Fourier transformation) method. Finally, a liner interpolation device 5 finds the internally dividing points of 1:3 and 3:1 between adjacent picture data by interpolation, doubles the picture by using the interpolating points only, and displays the enlarged picture on a display device 6 having double resolution against collected data. Therefore, the high-frequency emphasized part offsets the frequency deteriorated part in the double magnified picture thus obtained and frequency deterioration of the picture can be prevented.

Title: Optical head
Inventor: ANDOU HIDEO
IPC: G02B7/28
Filed: 1982-09-21
Abstract: PURPOSE:To extract asymmetrical light with simple constitution by providing a mask which shuts off or scatters light in a part of an optical element which detects the reflected light of the light beam condensed on a recording medium. CONSTITUTION:The laser light emitted from a semiconductor laser 12 is condensed through a collimator lens 13, a polarization beam splitter (PS) 15, a lambda/4 plate 16, and an objective lens 17 onto a recording medium 4. The reflected light advances reverse to pass through the PS 15 and a half mirror 18 and is condensed by an optical lens 24 onto a photodetector 26, by which the out of focus is detected. The light asymmetrical with respect to the optical axis is extracted by the effect of a mask 36 and is condensed on the photodetector 26 when the light passes the lens 24. Since there is no need for a knife edge for extracting asymmetrical light, the constitution is simplified.

Title: Shutoff valve unit with nozzle
Inventor: KOJIMA TERUHISA
IPC: F16K31/06
Filed: 1987-06-30
Abstract: PURPOSE:To permit a valve unit to accurately hold its relatively separating distance from a nozzle by connecting the valve unit to the point end of a plunger through a valve shaft of non-magnetic material and a shutoff plate of magnetic material to the bottom surface of the nozzle. CONSTITUTION:Dividing a shutoff valve unit into a plunger 4 and a valve shaft 5a, a valve unit 5 and the valve shaft 5a, using a material consisting of non- magnetic substance, are connected to the plunger 4. A nozzle 8 is constituted of a cylindrical part 19, O ring 20 and a flange part 1, and a ring-shaped shutoff plate 22, consisting of magnetic substance, is provided in the bottom surface of the flange part 21. Since a protruding part of the plunger 4, when it is retracted, from a solenoid 3 is formed by the non-magnetic substance, a magnetic field can be left confined inside the solenoid 3. While when the plunger 4 is protruded, the magnetic field limits its leakage range by the shutoff plate 22.

Title: Overload protecting device
Inventor: SHINOHARA SHIGERU
IPC: H02P29/02
Filed: 1982-09-18
Abstract: PURPOSE:To protect a motor against overload by setting the rotating speed which is reset to the normal rotating speed control state from an overload operation state to smaller value than the rotating speed which is shifted from the normal rotating speed control state to an overload operation state becoming overload. CONSTITUTION:When a load is applied to a motor 3 to decelerate the motor 3 so that the motor becomes a rotating speed corresponding to the overload, the output of a comparator 11 becomes high level, a photodiode of a photocoupler 12 emits a light, and the photodiode becomes ON. A shunt resistor 39 shares the charging current to a condenser 43 to delay the charging of the condenser 43, the conducting angle of a semiconductor control element 4 is reduced to decrease the applied voltage to the motor 3, thereby suppressing the load current. When an overload is removed, the photodiode stops emitting the light, the phototransistor is turned OFF to become the normal rotation control state.

Abstract: PROBLEM TO BE SOLVED: To suppress depletion of a gate electrode by respectively doping multilayered amorphous semiconductor films on PMOS and NMOS, forming regions with an acceptor and a donor, and then melting the whole surfaces of the amorphous semiconductor films with a laser light. SOLUTION: After an amorphous Ge film 2 is formed on an Si substrate 4 to be subjected to element separation 3 as an Si-Ge combination, an amorphous Si film 1 is formed on the film 2 and irradiated with a laser light. In this case, an insulating layer of SiO2, etc., is formed as a base. In the melting- polycrystallizing process under the irradiation of the laser light, a thick gate layer can be melted and activated with laser light having extremely low power, and in addition, doping impurity can be uniformly activated more efficiently without causing insulation deterioration, etc., in the base gate insulating layer. Consequently, the depletion of a gate electrode can be suppressed by easily forming the electrode to a prescribed thickness.
