Abstract: PURPOSE:To reduce the thermal stress in a joint sealing part of an optical waveguide body by coating the outer periphery of the optical waveguide body with a joint material to be softened and fused at a temperature lower than that of the optical waveguide body and including a thermal expansion coefficient difference between the joint material itself and a ceramic wired substrate for embedding the optical waveguide body within a specific range. CONSTITUTION:A thousand thin optical fiber strands each of which consists of a core with high light transmissivity and a clad part are bound and respective clad parts of these strands are joined and fixed with each other. The outer periphery of the optical fiber flux 1 is coated with a glass tube 2 having almost the same heat softening property as that of the optical fiber flux 1 to form the optical waveguide substance. The outer periphery of the optical waveguide body is coated with the joint material 3. The joint material 3 is formed by a glass component softened and fused at a temperature lower than that of the optical waveguide body and having <=+ or -5X10<-7>/ deg.C difference of thermal expansion coefficients between the material 3 itself and the ceramic wired substrate for embedding the optical waveguide body.

Filed: 1985-05-21
Abstract: PURPOSE:To permit to cool directly a molten resin to an objective temperature under keeping the property of kneading by pouring inert gas from a pouring port and discharging it out of a vent port. CONSTITUTION:A barrel 12 is provided with a feed port 16, connected to a hopper 15, the vent port 17, connected to a vacuum source, and the pouring port 18, connected to the pressure source of the inert gas, sequentially from the right side thereof while the material resin in the hopper 15 is molten in the barrel 12 and the molten resin is sent to the left. The inert gas, poured by pressure from the pouring port 18, flows to the right because a kneading disc 13 is equipped at the left side of the port 18 and is discharged through the vent port 17 located before the kneading disc 14. In this case, the inert gas deprives the heat of molten resin and the amount of temperature decrease of the resin is determined by the amount of inert gas flowed therethrough.

Title: Combustion device for slurry fuel
Inventor: KAWAGUCHI YOSHITO
IPC: F23D11/38
Filed: 1984-05-30
Abstract: PURPOSE:To enable excellent dispersion of solid fuel particles in slurry fuel, by forming a space part in a sprayer plate. CONSTITUTION:Slurry fuel F fed through a slurry passage 3 produces a violent swirl flow within a slurry dispersion chamber 14. Solid fuel particles contained in the fuel, forming a particle lump consisting of a single particle or a relatively small quantity of particles, are effectively dispersed, and flow to a spray chamber 14b through a slurry injection nozzle 14a. The slurry fuel injected from the spray chamber 14b is burnt such that, in a fuel injection passage 7 formed in a manner that it crosses the passage axis of the slurry dispersion passage 14, solid particles, of which a particle lump consists, are further dispersed and atomized with a violent jet of steam and are injected through a nozzle 13. As noted above, the particles injected through the nozzle 13 are injected in an excellent dispersed condition, and this increases the ratio surface area of an individual particle in the sprayed slurry and improves ignitability and combustibility, resulting in shortening of flame and improvement of controllability.

IPC: G11B5/64
Filed: 1985-05-21
Abstract: PURPOSE:To protect the titled disk from mechanical contact with a magnetic head by laminating a film consisting essentially of amorphous carbon on a continuous magnetic thin film of iron oxide. CONSTITUTION:The surface of a nonmagnetic Al alloy substrate 1 is anodized 2, the surface is specularly finished and then a thin Fe3O4 film 3 is directly formed on the substrate 1 heated at 200-270 deg.C by using a target consisting essentially of iron and added with 2-3wt% copper and cobalt. Then the film is heated in the atmosphere at 300 deg.C for three hr to form a thin Fe2O3 film. Then after the surface of the magnetic film 3 is etched by sputtering, a carbon thin film 4 is coated in 100-1,000Angstrom  thickness by using a target obtained by sintering high-purity graphite powder. Since the thin film 4 is amorphous and extremely hard, excellent wear resistance is exhibited during the sliding of a magnetic head and the friction coefficient is also reduced.

Title: Magnetic tape drive system
Inventor: SAIJIYOU HIROAKI
IPC: H02P3/12
Filed: 1978-09-04
Abstract: PURPOSE: To prevent a cinching phenomenon from occurring by shorting the supply terminal of a motor in a stop of a tape and then by releasing the shorting when a short current exceeds a fuxed value.  
     CONSTITUTION: The moment stop signal D is inputted to terminal (d), a supply of tape drive signal A stops and a current supply to reel motor M is interrupted. At the same time, signal E from braking control circuit BDU turns transistor TrQ 2  ON to short terminals (b) and (c) of motor M, thereby braking motor M. This short current is fed as reel motor voltage signal B back to circuit BDU by resistance R. When signal B exceeds a fixed value, output signal E of circuit BUD is cut off and TrQ 2  turns OFF as the result to release terminals (b) and (c); when signal B is less than the fixed value, TrQ 2  is turned ON to form a short circuit between terminals (b) and (c). In this way, the braking of motor M is intermitted, so that no cinching phenomenon will occur.

Title: Solid state image pickup device and its manufacture
Inventor: KATANOSAKA RYUJI
IPC: H01L27/148
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To reduce a film thickness of a film which will be an underlying layer of a light shield film and resin smear by a method wherein an opening is formed in a portion corresponding to each photodetector of the light shield film formed via an insulation film on an impurity containing silicon glass film, and is formed in a depth which does not reach the impurity containing silicon glass film. SOLUTION: An opening 8 is formed by etching selectively a light shield film 18, in a depth which does not reach a phosphorus silicon glass PSG film 15. A plasma silicon nitride P-SiN film 20 covers the light shield film 18 containing a formation part of the opening 8. According to such a solid state image pickup device, as the opening 8 is formed in a depth which does not reach the PSG film 15, even if a thickness of the PSG film 15 is thin, fluctuations of a white point fail do not occur and there is no risk that a manufacturing yield reduces. Thus, it becomes possible to reduce a film thickness of the PSG film 15 which is an underlying layer of the light shield film 18, and in its turn, an attempt can be made to reduce resin smear.

Abstract: PURPOSE:To amplify entrance laser pulse light to have necessary energy by taking out entrance laser pulse light passed through active medium after sufficiently amplify in closed loop or repeatedly reflecting light passage. CONSTITUTION:Pulse laser 30 having S polarization component is entered to polarization element 27 and then entered to active medium 23 and amplified and entered to reflect mirror 21. The reflect mirror 21 passes this light to polarization surface rotary element 29 previously apllied by half wave voltage. The light becomes P polarization component by passing through the element 29. Then the half wave voltage is released. The light passed through the element 29 further passes reflect mirrors 24,25, active medium 23 and polarization element 27 as amplified and enters to a mirror 26. The light is reflected by the mirror 26 and return the aforegoing light passage to the reflect mirror 20 and there the light again is reflected and the light is repeatedly reflectd beween the mirrors 20 and 26 as amplified. To output this laser light, half wave voltage is applied to the element 29 immediately after the light of P polarization component passes through the element 29. Thus, the light becomes S polarization component and is reflected by a polarization element 28 and taken out as light 35.
