Patent JP-H01238181-A (JP)
Title: Semiconductor light emitting device
Inventor: OGITA SHOICHI
IPC: H01S5/12
Filed: 1988-03-18
Abstract: PURPOSE:To alleviate an electric field concentration near a 1/4 wavelength shifter and to uniformize an optical intensity distribution over a whole resonator by disposing diffraction gratings only at both ends in a 1/4 wavelength shift DFB laser, and equalizing it at the center to that of a normal Fabry-Perot laser. CONSTITUTION:A diffraction grating 4 is not formed on a whole waveguide layer 3, but gratings 4, 4' are formed only at both ends near the end face 7, and the grating is not provided at the central region. Accordingly, the central region is formed in a uniform part 8 having uniform thickness of the layer 3 similarly to that of a conventional Fabry-Perot laser. However, to form a 1/4 wavelength shift type, the space phases of the grating 4 at the connector of the part 8 to the two gratings 4, 4' are displaced by 1/4 wavelength. That is, the gratings are isolated in the 1/4 wavelength shifter, and the connector to the part 8 provided between the gratings 4 and 4' is formed as 1/4 wavelength shifters 9, 9'. With this configuration, the optical intensity distribution does not have a peak at the center, but is largely uniformized in comparison. Accordingly, even if the resonator length L is increased, a stable laser operation is maintained, thereby realizing a narrow beam width laser.

Title: Three-electrode magnetron sputtering device
Inventor: IWAMA RYUJI
IPC: C23C14/42
Filed: 1988-03-19
Abstract: PURPOSE:To uniformize the film-thickness distribution of a thin film formed on a substrate by attaching an anode between targets and also providing plural filaments which double as cathodes to the outer ends of the targets. CONSTITUTION:In a three-electrode magnetron sputtering device, targets 2, 3 are attached to a target stand 1. When filaments 5, 5 at both ends of a target stand 1 are connected to the negative pole of a D.C. power source 7 and an anode 8 attached between the targets 2, 3 is connected to the positive pole, electric fields E orthogonal to magnetic fields H generated at magnets 4, 4 are formed on the respective surfaces of the targets 2, 3. When electric currents are applied to the filaments 5, 5 by means of an A.C. power source 6 to heat the filaments 5, 5, electrons are emitted along the electric fields E, by which the electrons emitted from the filaments 5, 5 are allowed to perform cycloidal motions on the targets 2, 3 and increase the ionization of the gases introduced through inert gas-introducing holes 9, 9. As a result, plasma density is increased and sputtering efficiency can be improved.

Title: Dehumidifying membrane
Inventor: NAKAHARA SEIICHI
IPC: B01D71/40
Filed: 1988-03-18
Abstract: PURPOSE:To prevent the dehumidifying performance of a dehumidifying membrane of a PVA-based polymer from being affected by the steam content of mixed gas by incorporating an isobutylene-maleic anhydride copolymer, a salt thereof, gelatin, etc., into the membrane. CONSTITUTION:One or more among an isobutylene-maleic anhydride copolymer, a salt thereof, gelatin and polyvinylpyrrolidone are incorporated into a dehumidifying membrane of a PVA-based polymer by about 10-200wt.%. The dehumidifying performance of the membrane is made independent of the steam content of mixed gas. The performance of a dehumidifying membrane of PVA deteriorates extremely in accordance with the lowering of the steam content.

Title: Buried semiconductor laser and manufacture thereof
Inventor: SUGAO SHIGEO
IPC: H01S5/00
Filed: 1988-03-18
Abstract: PURPOSE:To reduce a leakage current in a current blocking layer, to decrease a parasitic capacity, to perform a low threshold value and a high speed operation, and obtain a high manufacturing yield by providing a resonator direction parallel to orientation <01 > on a surface in plane (100) so that an active region, first and second conductivity type semiconductor layers are in contact with a semi-insulating semiconductor layer in plane B (111) and plane (100). CONSTITUTION:In a first step, two stripelike SiO2 mask layers 20a are formed by a photolithography method in orientation direction <01 > on an N-type InP substrate 10 in plane (100), and a double hetero structure made of an active layer 12, a clad layer 13 and a contact layer 14 is epitaxially grown by a hydride vapor growth. Then, in a second step, after an SiO2 mask layer 20b is formed by a photolithography method on the upper face of a double hetero structure from which the layer 20a is newly removed, a semi-insulating semiconductor layer 18 is buried and grown by a halide vapor growth in the groove made of plane B (111) and plane (100) formed in the first step. Since this semiconductor layer has a less leakage current by a current blocking layer and small parasitic capacity, its low threshold value and high speed operation is performed.

Title: Vacuum valve
Inventor: TEZUKA MITSUO
IPC: F16K1/20
Filed: 1984-04-05
Abstract: PURPOSE:To lessen fastening force of a valve by coupling an open-and-close valve to a driving shaft having a horizontal rotary shaft on a straight line vertical to the open-and-close valve with a link and an arm. CONSTITUTION:A valve seat 1 is opened and closed by an open-and-close valve 2, and the open-and-close valve 2 comprises a rotary shaft 3 not to produce friction with the valve seat at the time of opening and closing. The driving shaft 4 is on s straight line vertical to the open-and-close valve at the central point of the open-and-close valve 2. The valve is opened and closed by an arm 5 coupled to the driving shaft 4 and a link 6 to change the turning torque of the shaft 4 to fastening force. Accordingly, in case of rotating the shaft, if the piston force of an air cylinder is produced by a link motion from the outside air of the valve, the diameter of the air cylinder may be small to reduce the whole valve to a compact size.

Title: Antenna device
Inventor: TSURU TERUHISA
IPC: H01Q1/50
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To improve antenna radiation efficiency. SOLUTION: A dielectric board 2 is board on which a chip antenna 1 and a transmission reception circuit module 3 are mounted. A feeder 4 is a line for supplying a high frequency signal from the transmission reception module 3 to the chip antenna 1 and forms a coplanar line 14 together with an antenna side ground conductor 10. The antenna side ground conductor 10 and a feeder side ground conductor 11 are formed by providing a slit 12 to the ground conductor. In this case, the slit 12 does not completely separate the ground conductor into two, but is provided so as to leave a part of the feeder 4 (connection ground conductor 13).  Since the connection ground conductor 13 acts as a high frequency choke to a high frequency current flowing to the feeder side ground conductor 10, the high frequency current flows up to the feeder side ground conductor 11 to suppress a bad effect on an antenna radiation field.
