Title: Optical fiber
Inventor: YAMAGISHI YOSHIO
IPC: G02B6/02
Filed: 1986-09-09
Abstract: PURPOSE:To improve the absorption efficiency of light from a light source to efficiently transmit the light by providing a non-reflective coating layer on the face, which the light from the light source is made incident on, of a core front end part. CONSTITUTION:An optical fiber 1 consists of a core 2 and a clad 3 coating the core 2 and a front end 4 of the core 2 is formed into a cone for the purpose of increasing the absorption efficiency of light from a light source 5. The front end 4 of the core 2 is provided with a nonreflective coating layer 6. An inorganic compound like an Al oxide, an Si dioxide, a Ti oxide, or an fluoride or an organic compound like Teflon, an epoxy, or a polyimide is coated with an optical film thickness 1/4lambda0, preferably with a combinational film thickness of 1/4lambda0 and 1/2eta0 and vapor-deposition, ion plating, or electrostatic coating is performed to form the non-reflective coating layer 6. Since the optical fiber 1 has the non-reflective coating layer in the core front end part, reflection of light due to mismatching of refractive index on the boundary between the optical fiber end face and a medium and the angle dependency on the angle of incidence are reduced.

Filed: 1983-11-11
Abstract: PURPOSE:To hold moisture generated at the fixing time temporarily and to prevent the generation of paper wrinkles by forming a prescribed uneven surface on the surface of a pressing roller contacting with a heat roller. CONSTITUTION:The pressing roller 11 contacting with the heat roller 1 is constituted by laminating an elastic layer 13 and an uneven surface layer 14 successively around a roller base material 12.

Filed: 1984-10-11
Abstract: PURPOSE:To obtain LSIs of high reliability which produce no cracks in the cover film at the time of sealing, by a method wherein double layers consisting of metallic layer and an organic substance insulation layer are adhered at a time or more, and a required pattern is formed in this formed. CONSTITUTION:After adhesion of a CVD cover film, the wafer is coated with an Mo layer 19 of 2,000Angstrom  thickness by sputtering. Thereafter, a precursor varnish of polyimide is applied by spin and baked for 1hr at 80 deg.C, and polyimide is developed by transcribing a required pattern; then, a polyimide film 20 of approx. 1-2mum thickness is obtained by baking for 1hr at 140, 200, 350 deg.C, respectively. The Mo layer 19 and the CVD cover film 18 are plasma-etched with the mask of the polyimide film 20, and a protection film is formed by dipping in a solution of acetic acid to stabilize the polyimide surface, rinsing, and drying. Further, the wafer is subjected to back polishing, back etching, annealing, and back Au evaporation. Such a manner can prevent the generation of cracks by decreasing the resistance against resin flows at the time sealing because the film surface more flattens by a thickness of 1mum or more.

IPC: B64G1/28
Filed: 1988-08-30
Abstract: PURPOSE: To automatically restore the lost earth direction of the yaw-directional axis of the satellite by making it possible to resupply the energy of a flywheel and an earth sensor, measure the rotational frequency or angular speed of the flywheel, and measure or predict each angular momentum of the satellite when the pitch directional attitude passes a zero point. CONSTITUTION: A new angular speed ωc which decreases or increases the rotational frequency of the flywheel 7 alternately is commanded each time the pitch-directional attitude detected by the earth sensor passes another zero point (θ=0). In this case, the variation in the commanded angular speed is qHs /Iw (Hs is the angular momentum of the satellite 2, Iw is the moment of inertia of the flywheel 7, and the coefficient (q) is represented as 1<q<2). Lastly, this is repeated until the angular momentum of the satellite 2 decreases below a previously given value Hso when a zero point is passed. Consequently, the satellite can speedily and automatically be re-set to its correct pitch-directional attitude at low cost.
