Title: Electrofusion coupling
Inventor: NISHIKATA NOBUHIRO
IPC: F16L47/02
Filed: 1999-02-17
Abstract: PROBLEM TO BE SOLVED: To enable fusion in a uniform state by embedding a heating element in tube socket inner peripheral surfaces on both ends of a thermoplastic resin coupling main body, forming a corrugate part in a central part, and bending a socket in the inserting direction of a resin tube. SOLUTION: A heating wire 2 is embedded in a resin coupling main body 1, and a corrugate part 3 having a recess/projection part is formed on an outer peripheral surface of the central part. The corrugate part 3 secures a specified thickness, and an inner peripheral surface is reduced in an inside diameter by depth quantity of a recessed groove. A corrugate part 3 similar to the outer peripheral surface may also be arranged on the inner peripheral surface. A resin tube is inserted into a socket of the coupling main body 1, and an electric current is carried to the heating wire 2 from connector pins of both end parts so that the resin tube is fused on a coupling.  When the resin tube is inserted in a state of applying bending force to the resin tube when inserting the resin tube into the socket, the corrugate part 3 bends by following the axis of the resin tube to which the bending force is applied. Thus, circumferential directional clearance surrounded by a socket inner peripheral surface and a resin tube outer peripheral surface is uniformized, so that the whole periphery can be normally fused.

Title: Both direction clutch
Inventor: ITO KENICHIRO
IPC: F16D41/08
Filed: 1988-02-19
Abstract: PURPOSE:To obtain the compact structure and cut production cost by forming a sprag whose outer surface is constituted of two clutch cylindrical surfaces having difficult radius of curvature and in which the centers of radii of curvatures of the both partial cylindrical surfaces are offset. CONSTITUTION:The part of a sprag 4 which contacts an outer peripheral engagement surface 7 is formed from a partial cylindrical surface 17 having radius R of curvature, while the part which contacts an inner peripheral engagement surface 6 is formed from a partial cylindrical surface 18 having a radius (r) of curvature. The centers O and O' of the radii of curvatures of the partial cylindrical surfaces 17 and 18 are offset. Since the radial gap is exceedingly small between the partial cylindrical surfaces 17 of the sprag 4 and the outer peripheral engagement surface 7 of an inner ring 3, if the inner ring 3 turns in the leftward direction, the sprag 4 tilts rightward, and is wedge-engaged with the both engagement surfaces 6 and 7, and locked. Therefore, a turning moment is transmitted to an outer ring 2 from the inner ring 3 through the sprag 4, and the inner ring 3 and the outer ring 2 are integrally revolved in the leftward direction. Further, if a holding device 5 is shifted in the turning direction, a pocket 9 tilts the sprag 4 in the leftward direction in a moment, and the wedge engagement is released.

Title: Method for continuously casting cast slab having little inclusion
Inventor: YAMAMURA HIDEAKI
IPC: B22D11/114
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To restrain the capture of inclusion into the inner part of a cast slab by giving static magnetic field having a specific intensity to molten steel flow spouted from an immersion nozzle and controlling the spouted flow in a suitable state. SOLUTION: The molten steel is poured into a mold while holding the magnetic field intensity so as to satisfy Stewart number N into the range of 3×10 to 5×10<2> corresponding to the molten steel flow speed decided by casting speed, shape of the immersion nozzle, angle of a spouting hole, size of the cast slab, etc., by using a law of similarity of Lorentz force and inertia force of the molten steel flow, i.e., the equation of the Stewart number N = Lorentz force/inertia force =σB<2> L/ρV. Then, in the equation, σ is electric conductivity, B is the intensity of magnetic field, L is the thickness of the cast slab, ρ is density and V is the molten steel flowing speed at the upper end of the magnetic field zinc.  Further, the molten steel flowing speed V uses the measured value with an electromagnetic flow meter embedded in the mold or the value obtd. by simulating the molten steel fluid in the mold with a numerical calculation, etc., and it is desirable to adjust the N value by changing the intensity of the magnetic field at any time according to the variations of the casting speed, width, etc.

Title: Heat pump type air conditioner
Inventor: WATANABE YUKIO
IPC: F24F1/00
Filed: 1989-02-17
Abstract: PURPOSE:To improve heating rise performance and enhance defrosting characteristic by installing a reaction heat exchanger which is capable of heating an absorption agent which reacts with an absorption medium and indicates reciprocal heat absorption and heat generation with a heating means, into a ventilation circuit so that it may exchange heat with a heat exchanger, and placing a damper which interrupts the ventilation to the reaction heat exchanger, to said ventilation circuit. CONSTITUTION:When heating operation starts, closing dampers 5a and 5b are simultaneously closed and the water in a reserve tank 6 moves to a reaction heat exchanger 4, reacts with zeolite 24, and gets exothermic. This built up heat exchanges heat with a main heat exchanger and serves as indoor heating source. As absorption reaction occurs promptly, hot air is available immediately after the heating operation starts. When a fixed amount of water moves and the reaction ends, the solenoid valve 8 is closed by a control mechanism. Then, regeneration operation follows. During the regeneration operation, the closing dampers 5a and 5b are opened so that the zeolite 24 may be heated by a heating means, such as a heater built in heating tubes 23. The zeolite 24 discharges water as vapor. The discharged vapor moves into ventilated air through metal meshes 21 and it is blown off indoors by a straight line-flow fan.
