Patent JP-S6369288-A (JP)
Title: Manufacture of semiconductor laser device
Inventor: SHIGIHARA KIMIO
IPC: H01S5/00
Filed: 1986-09-10
Abstract: PURPOSE:To effectively etch only an N-type Ga1-uAluAs layer by using an etchant exhibiting larger etching rate for the layer which becomes a current narrowing layer than a P-type Ga1-zAlzAs layer which becomes a clad layer. CONSTITUTION:A Ga1-xAlxAs layer 2 which becomes a clad layer, a Ga1-yAlyAs layer 3 which becomes an active layer, a P-type Ga1-zAlzAs layer 4 which becomes a clad layer and an N-type Ga1-uAluAs layer 5 which becomes a current narrowing layer are sequentially epitaxially grown on an N-type GaAs substrate 1, a pattern is formed on the layer 5, removed by etching until the layer 4 is exposed, and then a P-type Ga1-vAlvAs layer 7 is grown. An etchant selects to exhibit faster etching velocity for the layer 5 and not to etch the layer 4. Such an etchant is used to effectively remove by etching only the layer 5 without immersing the layer 4 to form an internal stripe structure with good reproducibility.

Title: Laminated filter
Inventor: KUSUDA MASATAKA
IPC: B01D63/08
Filed: 1986-09-11
Abstract: PURPOSE:To exclude the early fatigue failure of a membrane at a fulcrum at the time of supporting the membrane with many fulcrums, by placing the waveforms of the corrugated surfaces of the opposed membrane supporting sheets of the unit adjacent to each other in the same phase. CONSTITUTION:A membrane 12 is laid over both faces of a corrugated sheet 11 in the form of a triangular wave, etc., to form a unit 1, and the units are laminated to form a raw liq. passage 2 between the units in the laminated filter. In this case, the triangular waveforms of the adjacent membrane supporting sheets are placed in the same phase. By this method, although the membrane is expanded by the raw liq. pressure and bent inward and the raw liq. passage 2 is meandered, the flow velocity of the raw liq. can be fixed since the width of the passage is constant, the surging of the raw liq. flow due to repeated variations in the flow velocity can be excluded, the vibration of the membrane can be avoided, and the early fatigue of the membrane can be prevented.

Filed: 1987-08-29
Abstract: PURPOSE: To avert the fault of operation by the tacky adhesiveness of a surface by allowing the unsoaked parts of a waterproof coating material to exist in the inside near the surface of a fiber sheet member on the rear surface side. CONSTITUTION: An opaque colored coating material for forming a coating material layer 2 is applied on the front surface of the fibrous sheet member 1 to impregnate the section of the fibrous sheet member 1 with the material, by which the parts 6 impregnated with the opaque colored coating material are formed and the fibrous sheet member 1 and the coating material layer 2 are partially duplicated and laminated. In such a case, the application is so executed that the remaining parts of the fibrous sheet member 1 are assured as the unsoaked parts 4 of the colored coating material. The unsoaked parts 4 of the coating material are formed as the parts to be impregnated with adhesives which contribute to the additional improvement in the adhesive power based on an anchor effect.  The parts to be impregnated with the adhesives impart a tacky adhesive layer 9 to the sheet, thereby contributing as the parts to be impregnated with the tacky adhesives and to hold the adhesives in the case the sheet is used as the light reflective tacky adhesive sheet. As a result, the tacky adhesives embrace the fibers and make the peeling difficult.

Title: Reactor for photosynthesis
Inventor: MORI TAKASHI
IPC: C12M1/00
Filed: 1982-12-08
Abstract: PURPOSE:To enlarge the scale of a rector for photosynthesis and to improve production efficiency, by providing a reactor with many reaction tanks for photosynthesis having outer peripheral walls set at given intervals, consisting of hexagonal transparent members, and reflecting plates arranged between the reaction tanks. CONSTITUTION:The many reaction tanks 10 for photosynthesis having the outer peripheral walls 11 consisting of hexagonal transparent members are set at given intervals, and the reflecting plates 20 are arranged between the reaction tanks. Light rays reflected by the reflecting plates 20 are introduced through the outer peripheral walls 11 of the transparent members into the reaction tanks 10. In the operation, since a great number of light radiators are installed in the reaction tanks 10, and the light rays introduced into the tanks 10 are transmitted through the outer peripheral walls of the light radiators or air layers in the light radiators, the light rays are introduced more effectively into the inside, and contribute more effectively to photosynthesis reactions in the tanks 10. Consequently, the scale of a reactor for photosynthesis is enlarged, sunlight and/or artificial light are more effectively utilized, to improve production efficiency.

Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent the deposition of a hygroscopic combustion ash, to obviate the wear of the flue and heat-transfer tube and to reduce the equipment cost. SOLUTION: The coarse-grain powder 3 of combustion ash, sand, etc., from the upstream side of a denitrator 4 is supplied to a waste gas from a powder feed part 6, the ash is liberated from the surface of a catalyst by the collision of the coarse grain with the ash depositing on the catalyst, and the deposition of the combustion ash contg. a heavy metal as a catalytic poison and a deliquescent salt on the denitration catalys is prevented so that the catalytic activity is not deteriorated. If a catalyst 5 coated with combustion ash is stored as such, the catalytic poison is infiltrated and the pore is closed due to the deliquescence of the combustion ash, and the catalytic activity is lowered.  The powder is intermittently supplied when the combustion is started or suspended in the waste combustion gas source, and the solid powder is continuously supplied when the combustion is conducted in the source.

Title: Conversion method for voice information cell and assembling and disassembling device for the cell
Inventor: OSADA KAZUHIKO
IPC: H04L47/2416
Filed: 1996-08-16
Abstract: PROBLEM TO BE SOLVED: To effectively transmit both voice and data information with use of a single cell by packing a data packet into a free space of the cell that is produced, based on the cell assembling limit time. SOLUTION: The cell assembling limit time elapses when the compressed voice information are turned into the voice packets #1 to # and these packets are put into a cell. If no voice packet is generated in such cases, the data equivalent to the idle capacity of the cell are read out of a data information memory 16 and packed into the cell as a data packet. The data information is previously divided into the packets in the fixed length and packed into an idle part. If the idle capacity is smaller than the quantity of fixed length data, the data information Ds overflowed the cell is packed into the cell to be assembled next as a data packet. Thus, both voice and data information cells are filled with each relevant information and can be sent within the cell assembling limit time. Then the voice communication is possible with high efficiency and with no deterioration of the voice quality.
