Title: Sealing device
Inventor: KASAHARA FUMIAKI
IPC: F16J15/32
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To reduce the number of partitems and reduce a cost. SOLUTION: In a sealing device 3 formed such that a guide ring 4 and an oil seal 5 are assembled together, the surface of the guide ring 4 between an outer ring body 1 and the guide ring 4 is covered with an elastic substance 6 to form structure for ensuring sealing ability and this structure eliminates an O-ring used in a conventional type. This constitution further reduces a parts cost and labor required for assembly compared with a conventional type.

Title: Molding tool and molding method
Inventor: USUDA TOSHIYUKI
IPC: B29C45/04
Filed: 1994-03-29
Abstract: PURPOSE:To improve the accuracy in a helical gear part, by a method wherein in a turning-stop mechanism, the first movable mold is kept at a fitting-in condition at the time of mold break of a movable mold and stationary mold, and the first movable mold is made turnable freely at the time of ejection of the helical gear part by an ejection member after completion of mold break. CONSTITUTION:At the time of mold break, since the first movable mold 11 does not turn even if a mold release resistance from a stationary mold 6 is high due to a reason that a molded product 2 is a gate type molded product, in the molded product 2 an end face of a fitting part 4 is separated easily from a gate 27. Hereby, mold release is performed under a state where the helical gear part 3 is stuck to a gear part cavity 9 of the first movable mold A11A. Since a pin 30 is pulled out of a pin hole 32 after completion of the mold break, the first movable mold A11A of the first movable mold 11 becomes freely turnable by a bearing 12. Hereby, at the time of ejecton of the helical gear part 3 by the ejector pin 8, the first movable mold 11 turns smooth by the bearing 12 and the helical gear part 3 is released reliably.

Title: Controller for internal-combustion engine
Inventor: HOSOKAWA KAZUHIKO
IPC: F02D31/00
Filed: 1983-05-10
Abstract: PURPOSE:To heighten the output power of an internal-combustion engine and the efficiency of its operation and normalize its exhaust gas, by using the proportional integration/differentiation or proportional integration control signal of a revolution speed control unit to vary the air fuel ratio of the engine to automatically change its output power characteristic. CONSTITUTION:The buffer circuit 21 of an air fuel ratio controller 20 receives a proportional integration/differentiation (P.I.D.) control signal through a high impedance to prevent the signal from being affected due to the addition of the controller. When the level of the P.I.D. or proportional integration (P.I.) control signal of a revolution speed control unit 10 received as a load detection signal has exceeded the upper limit VH of the prescribed hysteresis width of a hysteresis comparison circuit 23, the air fuel ratio of an engine is dereased. When the level of the signal has become lower than the lower limit VL of the hysteresis width, the air fuel ratio is increased back to the original relatively-high value. The output power of the engine is thus adjusted.

Abstract: PURPOSE:To enable identifying of liquid to be identified having a low refractive index and detecting of water solution concentration, by using an optical transmission path in which transparent liquid is implanted into a clear pipe to form a core. CONSTITUTION:An optical transmission path 1 is constituted such that a clad 2 consists of an air layer, and clear liquid is implanted into a clear pipe 3 to form said liquid into a core 4. Light is transmitted through the core 4, and if liquid 5 to be identified is adhered to the outer periphery of the clear pipe 3 or said pipe 1 is eroded by said liquid 5, a clad 2 works in place of the liquid 5 to be identified, and strength of light outputted from the jet end of the core 4 changes to identify the type and concentration of the liquid 5 to be identified from said change. The refractive index distribution such that, since the refractive index of the core 4 is larger than that of the clad 2 due to an air layer, light is transmitted at the inside of the optical transmission path 1, but if the clad 2 produces the liquid to be identified, the refractive index of the liquid 5 to be identified is larger than that of the core 4, light leaks from the core 4 to the liquid 5 to be identified, and this causes changing of a strength of light outputted from the jet end of the core 4.

Title: Seal
Inventor: WASHIDA AKIRA
IPC: F16J15/44
Filed: 1978-07-06
Abstract: PURPOSE: To provide a seal having labyrinth function as well as pump function, by winding a metal wire into helical form and coating the outer surface of said helically wound metal wire with resilient material.  
     CONSTITUTION: Seal 4 is obtained by winding metal wire 1 having, for instance, a circular cross section into helical form 2 and coating the outer surface with resilient material 3 of high-molecular material or the like. The seal 4 thus obtained is fitted in the internal space of housing 5 and then shaft 7 is inserted into the seal 4 while leaving clearance 6 between them. With such an arrangement, when fluid passes through small gaps 8 and large gaps 9, velocity is increased at small gaps 8 whereas velocity is decreased at large gaps 9, which results in increasing of energy loss of the fluid, so that its leakage can be reduced. Further, since the gaps 8, 9 are in a helical form, a screw pump function is produced with rotation of shaft 7, so that leaking fluid is forced back by the pump function.
