Title: Solenoid valve installation structure
Inventor: ISHIKAWA MITSUO
IPC: F16K31/06
Filed: 1983-12-26
Abstract: PURPOSE:To prevent the air leak from the periphery of ventilating holes by interposing an air-leak preventing member between the installation surface of a solenoid valve and the equipment and installing an elastic bush which independently acts onto each ventilating hole and a seat for holding said elastic bush. CONSTITUTION:The both edge surfaces 7a of a rubber bush 7 are dimension-set so as to protrude a little from a seat surface 8b, and when the rubber bush 7 is interposed between a solenoid valve 1 and the equipment 2, the both edge surfaces 7a of the rubber bush 7 are closely attached onto the periphery of a ventilating hole 1a on the solenoid valve side and a ventilating hole 2a on the equipment side, and air leak is prevented. When the ventilating holes are filled with compressed air, the pressure tends to restore the original shape of the rubber bush 7 in elastic deformation state, and therefore the periphery of each ventilating hole is strongly pushed onto the edge surface 7a of the rubber bush 7, and air-leak preventing effect can be made sure furthermore.

Title: Spark-assist type alcoholic engine
Inventor: KUDAMATSU TAKAO
IPC: F02M61/10
Filed: 1985-10-30
Abstract: PURPOSE:To prevent misfiring of a alcoholic fuel when the load of an engine is low, by disposing an assist plug at a position confronting a jet port which is opened even when the pressure of fuel is low. CONSTITUTION:A nozzle body 10 has a plurality of jet ports 19, 20, and the number of the jet ports which are opened varies in accordance with the pressure of fuel. When the load of the engine is low so that the pressure of fuel is low, the lower jet port 19 is alone opened. Accordingly, even though the amount of injection is small in total, the amount of fuel injected from the jet port 19 becomes relatively large. An assist plug 43 is disposed at a position confronting the jet port 19. As a result, it is possible to prevent misfiring in a low load condition in which the temperature of combustion is low and the intensity of transmission of flames is weak, thereby it is possible to attain stable combustion.

Filed: 1983-12-23
Abstract: PURPOSE:To improve remarkably dust removing effect by providing a fixed impeller and a rotating impeller in the inside of a nozzle main body and ejecting double whirling streams caused by the action of both blades to an object to be cleaned. CONSTITUTION:When a nozzle for air shower is fitted to an air chamber or the like by utilizing a fitting seat 14 and a through hole 15 for fitting and used, the supplied air passes through the inside of the nozzle main body 8 and is ejected from an air jet port 10 which is opened in the prescribed direction. On this occasion, air collides first with each blade 33 of a fixed impeller 22 inside the nozzle main body 8 and rotating force is given to the nozzle main body 8 by said blades 33, therefore the main body 8 is rotated around an axial line 16C and the air jet port 10 is oscillated. Further, since a rotating impeller 24 is rotated by the air flowing inside the main body 8, the air steam becomes a whirling stream and is flowed out from the port 10. Therefore, double whirling steams having excellent dust removing effect are formed at the outside the nozzle.

Abstract: PURPOSE:To improve measuring accuracy by making the housing plate of an ionization chamber in a curved surface structure while being insulated from the open air by sealing. CONSTITUTION:An ion current flowing inside an ionization chamber is almost dependent on intensity of radiation and on the density of air inside the ionization chamber. The ionization chamber formed of a housing plate 10a is sealed up by sealing 12 at the part of an outer case 7 and air 11 in the inside is insulated from the open air so as to be not influenced by a change of a state of the open air. The housing plate 10a is a composed of a curved surface of a projection type or of a recessed type so as to suppress deformation of the outer housing plate 10a due to a pressure change of the open air extremely small. Thereby, density 8 of the air 11 inside the ionization chamber is held almost constant so as to enable a radiation amount to be correctly measured.

Abstract: PURPOSE:To bend a sheet material to an accurate angle by deviating one of the lower ends of an upper die from the other end to perform a primary bending, measuring an interval between upper and lower dies and a bent angle of a sheet and lowering the lower end of the upper die in parallel with the lower die down to a value calculated based on the measured value to perform a secondary bending. CONSTITUTION:The sheet 3 is put on the lower die 6 and in a ram stroke in the initial state, the left end of the ram is given by XL0 and the right end thereof is given by XR0. Then, since one end of the upper die 4 is deviated and the left end of the ram stroke is given by XL1 and the right end is given by XR1 to perform the primary bending, intervals between the upper and lower dies 4, 6 differ and the bent angles thetaL1, thetaR1 of the sheet material, too, differ, therefore, the relation of the bent angle after a spring back is generated to the stroke of the upper die 4 is calculated, a stroke calculated as the lower edge of the upper die 4 is set in parallel with the lower die 6 is added to the upper die to perform the secondary bending. Consequently, accurate bent angles thetaL3, thetaR3 can be obtained without needing a trial bending.
