Title: Semiconductor laser device
Inventor: WADA MASARU
IPC: H01S5/00
Filed: 1985-05-14
Abstract: PURPOSE:To limit a laser oscillating section into an extremely narrow region by selectively increasing the thickness of a clad layer in the vicinity of the ridge edge section of a semiconductor substrate. CONSTITUTION:A pair of ridges are projected from the main plane side of a semiconductor substrate 1 while thickness in the vicinity of the ridge side surface sections of an active layer 3 formed onto the main plane is made larger than that of other sections. The relationship of an optical output from the semiconductor laser device and currents has excellent linearity, and operating currents required for oscillating the laser device may be reduced. Since the thickness of a clad layer 2 on the top surfaces of the ridges 1a, 1b is shaped extremely thinly in the laser device, beams are absorbed to the substrate 1 in the sections on the top surfaces of the ridges, and oscillating sections are specified while the thickness of the clad layer 2 is increased in sections in the vicinity of the side surfaces on the outsides of the ridges 1a, 1b. Consequently, it is thought that the extension of currents is inhibited. The active layer 3 is also formed selectively in the same manner as the clad layer 2, thus further improving the effect of the inhibition of the extension of currents.

Title: Mold device for synthetic resin molded product and its manufacture
Inventor: KATAGAWA KOUSUKE
IPC: B29K105/20
Filed: 1989-04-21
Abstract: PURPOSE:To prevent a heating element from disconnection at the time of manufacturing and a recessed section from being formed after molding by forming a fluidizing port in a second channel disposed protrudingly in a first channel of a first mold, and fluidizing synthetic resin from the upper side and a second coating material disposed in a second channel. CONSTITUTION:A second coating material 12 is formed, and the second coating material 12 is fixed in a second channel 6 of a second mold 3. A heating element 10 is placed on the surface of the second coating material 12 and a first mold 2 is fixed on the second mold 3, and lastly fluidizing synthetic resin 4 is injected from a fluidizing port 8 into the second channel 6. Then, the fluidizing synthetic resin 4 once hits the upper surface of a first channel 5 of a first coating material 11 and flows from the upper surface of the heating element 10 to the left and right and back and forth to be filled in the first channel 5. Although the fluidizing synthetic resin 4 is injected under high pressure, the same is fluidized from the upper side of the heating element 10. Thus, even a foil-shaped heating element is free from disconnection and projected sections are not to be formed on the surface of a product after molding.

Title: Manufacture of thin film transistor
Inventor: KAWAI SATORU
IPC: H01L29/786
Filed: 1981-06-30
Abstract: PURPOSE:To obtain a high performance thin film transistor without variation in the operating point by forming the gate insulating film of the thin film transistor using hydrogenated amophous silicon in the same continuous steps, thereby suppressing the defect. CONSTITUTION:When gas containing oxygen or nitrogen is mixed with discharge atmosphere in an SiH4 glow discharge decomposition, the production of a high quality insulating film such as SiO2 or SiN4, is utilized. For example, a vacuum tank 1 is first evacuated, a substrate 5 formed with a gate electrode is heated by a heater 7, SiH4 is fed from a bomb 8, and oxygen is then fed from bomb 9, and electric power is applied from a high frequency oscillator 6. Then, the SiO2 is decomposed and deposited on the substrate 5 by the discharge between an anode 3 and a cathode 4. When the introduction of the oxygen from the bomb 9 is stopped, piling up of hydrogenated amorphous silicon is started.

Title: Method of filtering waste rice washing water
Inventor: IMURA SATORU
IPC: B01D29/00
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To meet the standards set for the discharge of waste rice washing water to sewerage by using a mesh filter of such a large mash that particles of maximum diameter of mixed particles in the waste water do not pass therethrough to filter the waste water. SOLUTION: Waste rice washing water containing mixed particles of 3 μto 1000 μ size is fed into a feed tank 1, and is drawn to an upper tank 3 through a pipe 3 by a drawing pump 2. In this state, the waste rice washing water in the upper tank 3 is sent into mesh filters 11 from a fall pipe 5. The waste rice washing water sent into the filters 11 is passed through meshes of the filters 7 and is returned to the feed tank 1. At the beginning, particles of large particle diameter mixed in the waste rice washing water are caught in the meshes of the filters 11. After that, however, by a capillary phenomenon in the particles, only water is passed through the filters 11 and is circulated as clean water. At this point of time, a switching cock 15 is switched so as to communicate with a drain pipe 17.

Abstract: PURPOSE:To reduce noise during running of a railway vehicle, by fitting an outer ring onto a core ring, which have polygonal fitting surfaces, respectively, with a predetermined interference ratio to effect a frictionally damping effect between the polygonal fitting surface. CONSTITUTION:A regularly polygonal ring-like member 4 having, for example, a regular dodecagon, is disposed between the fitting surfaces 3 of steel outer and inner rings 1, 2, and the outer ring 1 is fitted onto the inner ring 2 with an interference ratio in a range from 0.25/1000 to 0.8/1000 with both rings being locked by a stop ring 5. With the thus limited interference ratio it is possible to increase the restraint between the joint surfaces of the rings 1, 2 to restrain a slipping displacement therebetween. Thereby, it is possible to aim at enhancing the fractional damping of the wheel to reduce noise.

Abstract: PROBLEM TO BE SOLVED: To make highly efficiently performable degassing of even a liquid with a high viscosity by a degassing apparatus with a small size without causing disadvantageous pressure loss by immersing a degassing container having a gas permeation membrane and a gas permeation chamber in a gas-dissolving solution and removing the dissolved gas by permeating the gas through the gas permeation membrane while keeping the degassing container still. SOLUTION: The degassing container 1 is provided with a gas permeation chamber in the inside of a gas permeable membrane, equipped with a gas discharge pipe 13 for decreasing the pressure of the permeation chamber and a vacuum suction pump 14, and housed in a tank 2 as a whole. That is, the degassing container 1 is composed of overlaying two flat membrane 11 while sandwiching a spacer 13 for holding the permeation chamber, sealing the membrane by heat sealing, and connecting the gas discharge pipe 13 to the inside space between the flat membranes 11. The gas-dissolving solution is poured in the tank 2 and while keeping the poured solution still without forcibly moving the solution, the vacuum pump 14 is driven to carry out vacuum suction for the gas permeation chamber of the degassing container 1. In that case, the temperature gradation of the gas is generated in the solution accompanying the progress of the degassing, so that the gas in the solution is moved toward the membranes and discharged.

IPC: B22C7/00
Filed: 1981-07-02
Abstract: PURPOSE:To produce castings by green sand molds of good dimensional accuracy without making costly metallic molds by drilling fine holes in a wooden pattern, packing a synthetic resin in these holes and allowing the resin to cure. CONSTITUTION:Fine holes 8 are drilled in the cylindrical part 3 of a wooden pattern and a self-curing synthetic resin 9 is cast into these holes 8 to reinforce said parts. For example, an epoxy resin and the like are used for the self-curing synthetic resin. Since the cast resin cures after percolating partly in the soft parts of the wood, the resin columns and the wood parts are made into one body. The friction between both is large and the pattern withstands the compressive force during squeezing of the molding sand sufficiently.
