Title: Joint sheet
Inventor: WATANABE YOSHIOMI
IPC: B29B15/00
Filed: 1979-09-29
Abstract: PURPOSE: To provide a joint sheet which is inexpensive and elastic and has great strength, by a method wherein part of an asbestos fiber is replaced with an org. fiber.  
     CONSTITUTION: An org. fiber (pref. a polyester long fiber) is added to an asbestos fiber which is main material. A rubber material, a vulcanizing agent, an accelerating agent, an antioxidant, a filler, a solvent, etc. are blended with the mixt. The resulting blend is kneaded, heated and pressed between rollers to prepare an asbestos joint sheet. When an asbestos long fiber is used, there is obtd a joint sheet which has great strength and is highly elastic. Since the asbestos long fiber is expensive, the joint sheet produced is necessarily expensive. But, by using an inexpensive asbestos short fiber and a high-molecular org. long fiber which is readily available, the joint sheet having excellent characteristics can be produced at low cost.

Title: Anti-lock device
Inventor: YOSHINO MASATO
IPC: B60T8/70
Filed: 1987-05-20
Abstract: PURPOSE:To restore a wheel from locking within a safe range by detecting the peak of deceleration while pressure is being reduced, judging whether the restoration after that is smooth by a linear function, and outputting the holding command of a brake pressure. CONSTITUTION:As a brake is applied and wheel speed Vw starts to be reduced, a circuit 5 obtains a slip speed 1 from an estimated body speed Vv and a slip speed evaluating signal S, and, when the slip speed lambda is above a defined value lambda1, while deceleration being smaller than -b without the peak value of the deceleration being appeared, an AND circuit 14 gives an H output, whereas, when the peak value is detected, it gives an L output. Then, when the slip speed lambda becomes lower than a slip restoring threshold value lambda2, a signal O8 is made H via AND circuits 15, 16 while, at the same time, with a Dwd obtained by subtracting a defined evaluating value + (d) from the peak value as an initial value, if the deceleration is smaller than a deceleration change reference value Dl of a defined reduction ratio, an AND circuit 20 gives an L output to continue pressure reduction, while giving an H output when it is larger to keep the pressure constant. Thereby, a wheel can be restored from locking within a safe range.

Title: Electromagnetic fuel injection valve
Inventor: NAKANO YASUYUKI
IPC: F02M61/16
Filed: 1993-05-28
Abstract: PURPOSE:To enhance the axial bonding strength after caulking an adjuster by applying knurling to a caulked part in the case of adjusting the fuel injection quantity by adjusting the energizing force of a spring for pressing a ball valve to the seat face, by the adjuster caulked to a core. CONSTITUTION:When a current is applied to a coil 11, a magnetic circuit is formed by a core 2, a yoke 3 and a plunger 4, and the plunger 4 is sucked to the core 2 side. Then a ball valve 5 is integrally moved and detached from the seat face 6 of a nozzle 19. The fuel, therefore, flows into a fuel injection valve 1 through a fuel passage 16 and then turned by a swirler 20 and injected from an orifice 14. The fuel injection quantity is made variable by adjusting the energizing force of a spring 7 for pressing a ball valve 5 by an adjuster 8 caulked to the core 2. In this case, knurling is applied to the caulked part A of the adjuster 8. The dislocation of the adjuster 8 is thereby prevented so as to dissolve the slippage of the fuel injection quantity across caulking.

Abstract: PURPOSE:To contrive high integration density and high operation rate of LSI by realizing with the lift-off method the flat structure without burrs or V-shaped groove through utilization of high melting point metal such as Mo, W, Ti as the material for lift-off and through the high temperature treatment process. CONSTITUTION:The Mo film 11 is etched with the resist pattern 12 used as the mask and then the poly-Si film 3 is etched with the resist film 12 and Mo film 11 used as the mask. The SiO2 film is deposited thereon by the deposition method such as sputtering method, ECR type plasma deposition method etc. The SiO2 film is deposited like 13 on the upper surface of the Mo film 11 and simultaneously deposited like 14 at the side wall of the Mo film 11 and poly-Si film 3. When this structure is subjected to the isotropy etching, the V-shaped groove is formed since the etching speed of SiO2 film 14 is higher than that of the SiO2 film 13. This is placed in the thermal processing under N2 ambient for 30 minutes at a temperature of 900 deg.C and thereby the film quality of SiO2 film 14 is changed to the quality similat to that of the SiO2 film 13. Thereby, the desired structure is obtained by the isotropy etching. This is then subjected to the lift-off in the mixed solution of H2SO4/2H2O2.

Filed: 1988-05-24
Abstract: PURPOSE:To perform an operation without any trouble even under a high water temperature at the time of heating, by effecting heat exchange between a piping part extending from an outlet part of a water heat exchanger on the non-used side to a restrictor for heating and a piping part extending from a selector valve to an inlet of an accumulator. CONSTITUTION:A piping part 12 extending from an outlet part of a water heat exchanger 3 on the non-used side to a heating capillary tube 6 and a suction piping part 13 extending from an outlet of a four-way valve to an inlet part of an accumulator 9 are welded to each other over a predetermined length so as to exchange heat between the two piping parts. When the temperature of water subjected to heat exchange in the water heat exchanger 3 is high, the temperature of a refrigerant evaporated in the heat exchanger 3 is raised nearly to the water temperature to become a superheated gaseous refrigerant. In the suction piping part 13 extending from the four-way valve to the inlet of the accumulator, however, the superheated gaseous refrigerant is subjected to heat exchange with a low-pressure refrigerant cooled to a low temperature through decompression by the capillary tube 6, whereby the temperature of the refrigerant sucked into a compressor is lowered, and the discharge temperature is also lowered. Therefore, the compressor can be operated even under a high water temperature.
