IPC: H01S5/30
Filed: 1981-05-25
Abstract: PURPOSE:To improve the reliability of the semiconductor laser element by means of extending the lifetime thereof and eliminating the unfavorable influence arising from the transition region of the active layer interface by a method wherein the carrier concentration of the crystal growing layer comprising the semiconductor laser is controlled. CONSTITUTION:In the process laminating N type clad layer 2, active layer 3, P type clad layer 4 and cap layer 5 on an N type GaAs substrate, the transition region is formed by means of mixing the impurities in the N type clad layer 2 in the active layer 3. This transient region is formed likewise on the interface between the active layer 3 and the P type clad layer 4. In order to settle this problem, the carrier concentration n2 of the active layer 3 is specified to be higher than the carrier concentration n1 of the N type clad layer 2 while the carrier concentration n3 of the P type clad layer 4 is specified to be higher than the carrier concentration n2 of the active layer 3, i.e. the transition region between the active layer 3 and the P type clad layer 4 may be eliminated by means of specifying the carrier concentration to be n1<n2<n3.

Title: Assembly of carbon fiber bundle
Inventor: YUKI IKUO
IPC: H01Q17/00
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To enable carbon fiber bundles to be disposed at a prescribed interval in a frame by a method wherein a large number of carbon long fibers prescribed in volume resistivity are bound together with adhesive agent into carbon fiber bundles, and the carbon fiber bundles are fixed to a flexible support in parallel at a certain interval. SOLUTION: A carbon fiber bundle 2 is made of carbon long fibers whose volume resistivity ranges from 10<-4> to 10<4> Ω.cm. An assembly of carbon fiber bundles made of carbon fibers smaller than the above carbon fibers in volume resistivity is not excellent in radio wave absorbent properties. Carbon fibers larger than 10<-4> to 10<4> Ω.cm in volume resistivity are unstable and fragile. Epoxy resin is used as adhesive agent, and it is preferable that the carbon fiber bundle is formed like a pole 0.8 to 20mm<2> in sectional area. The carbon fiber bundles 2 are tied down with string 6 like a screen. Therefore, carbon fiber bundles can be arranged in a frame at a prescribed interval.

Title: Freely bendable light guide tube
Inventor: MIYAMOTO KEIGO
IPC: E04H1/00
Filed: 1987-04-01
Abstract: PURPOSE:To permit easy installation of piping in order to introduce the solar light, etc., into the basement of a building by forming a titled tube of annular bodies each having a projecting margin in one marginal part and a recessed margin in the other marginal part and having a specular surface on the inside peripheral face. CONSTITUTION:This tube is formed by stacking and inserting many pieces of light guide units consisting of the annular bodies each having the projecting margin 2a in one marginal part and the recessed margin 2b in the other marginal part and having the specular surface 3 on the inside peripheral face into a flexible tubular body in such a manner that the projecting margins come into contact with the recessed margins. Then, even if the flexible tubular body is bent, the projecting margins engage freely bendably with the recessed margins and, therefore, the dissipation of the light to the outside is obviated and the light can be reflected on the specular surfaces and transmitted in a desired direction. The solar light is thus introduced into the room or basement of the building where no solar light falls and such light is usable for living such as illumination, ornamentation and horticulture in the room.

Abstract: PURPOSE:To obtain a gate oxide film of high quality which is excellent in dielectric breakdown strength and oxide film defect density even if a low temperature treatment is employed by a method wherein fluorine ions are implanted into the gate oxide film after or before a gate electrode film is formed on the gate oxide film through a CVD method. CONSTITUTION:A semiconductor substrate 1 is thermally oxidized at a comparatively low temperature by the use of an oxidizing agent to form a gate oxide film 2. Then, a polysilicon film 3 is deposited as a gate electrode film through a vacuum CVD method. In succession, ions of <19>F<+> are implanted into the gate oxide film 2 through the intermediary of the polysilicon film 3 so as to enable their concentration peak to be located in an SiO2 film. Then, the substrate 1 is annealed in an atmosphere of N2 for 30 minutes to combine Si of unsaturated bond with F to saturate for the formation of a gate oxide film 2a doped with fluorine. A process follows, where the polysilicon film 3 is doped with impurities to be lessened in resistance, and the impurity doped film 3 is patterned into a required shape for the formation of a gate electrode 3a.

Abstract: PURPOSE:To provide a positive prevention of leakage of electromagnetic wave, improve a thermal efficiency and prevent any irregular heating by a method wherein an inner seal surface abutting against a front plate of a heating chamber is formed into a second door plate separate from a first door plate formed with a small hole therein and the second door plate is formed with a slant surface. CONSTITUTION:A first door plate 20 is formed with small holes 24 and a second door plate 25 separate from the door plate 20 is formed with an inner seal surface 26 to be contacted with a front plate 17. Due to this fact, the seal surface 26 is not influenced by a stain caused by a punching operation for the small holes 24, resulting in that a high degree of flatness is attained, a high degree of surface contact of an entire surface 26 in respect to the front plate 17 is got and then a leakage of electromagnetic wave is positively prevented. In addition, since there are a choke groove 30 and an outer seal surface 21 outside the surface 26, if an electromagnetic wave passes between the surface 26 and the front plate 17, its electromagnetic wave is further attenuated by the groove 30 and between the surface 21 and the front plate 17. A circumferential surface of a concave part 27 of the door plate 25 is made as an inclined surface 28, thereby an electromagnetic wave or a heat is reflected toward a central part of the heating chamber 13 so as to improve an efficiency and then an irregular heating is prevented.
