Title: Vibration reducing method of intermediate/low speed 4- cycle, 6-cylinder internal combustion engine
Inventor: MATSUI TAKEO
IPC: F16F15/24
Filed: 1978-06-22
Abstract: PURPOSE:To reduce engine vibrations, especially the tertiary vibration, by increasing the whole weight of the piston by 30-60% in an intermediate/low speed 4-cycle, 6-cylinder internal combustion engine by such a construction that the lower part of piston is formed large. CONSTITUTION:In a piston formed in combination of the piston proper 4 and a piston crown 2, the lower part of the piston's plug hole 3 is prolonged and thickened so that the whole weight of the piston increases by 30%. A further lengthening of the lower part of the piston's plug holew 3, an increase by 60% in the whole weight, makes the weights of the upper and lower parts approx. equal, and consequently can suppress the resultant force OB synthesized of component OA as the engine vibration, especially the tertiary vibration due to the combustion gas pressure acting against the basic line OX and component AB as the vibration due to inertia force at a reciprocating part. Thus, by lessening the tertiary vibration the lubrication oil film in the bearing part can be thickened and the extension of life can be expected.

Title: Vertical mosfet
Inventor: MORI SHOGO
IPC: H01L29/78
Filed: 1993-04-01
Abstract: PURPOSE:To improve avalanche withstanding voltage by preventing a local current concentration in a vertical type MOSFET. CONSTITUTION:The distance L1 between the P-type semiconductor region 14# of a body of a circumferential section and the P-type semiconductor region 14 of a body of the element region adjacent to it is shorter than the distance L2 between the P-type semiconductor regions 14, 14 of a body of a adjacent element region. Thus, the withstanding voltage is improved in the region facing the circumferential section where the distance between a body and a body is shorter. When the MOSFET is turned off in cases where the MOSFET is used as switching element with an inductive load connected, it is more difficult for the avalanche current to flow in the region facing the circumferential section than other element regions. Furthermore, the avalanche current flows nearly uniformly in other element region so that it is difficult for a local breakdown of the element to occur, thereby improving the avalanche withstanding voltage.

Abstract: PURPOSE:To detect a physical quantity highly accurately at a high SN ratio by introducing laser light whose wavelength is swept to a Fabry-P erot resonator wherein resonating waveform characteristics are changed in response to the physical quantity through a single mode optical fiber, and detecting the resonating output. CONSTITUTION:The single mode optical fiber 13 is coupled into a tube body 17 and fixed. Dielectric multiple layer films are evaporated on the surface of a thin plate 18 which is fixed to an opening part and the end surface of the optical fiber 13 and a light reflecting mirror is formed. Thus the Fabry P erot resonator 14 is constituted. The hollow space in the tube body 17 is communicated to the outside through a small hole 19. Therefore the thin plate 18 vibrates in the direction of an arrow in response to an external pressure P. When the laser light which is swept over a wavelength range is introduced to the resonator 14 from a laser oscillator 11 through the optical fiber 13, the resonator 14 is resonated at the wavelength corresponding to the conditions of the resonator 14. The light is inputted to the laser oscillator 11, and the decrease in the oscillating outputs is detected by a light detector 12. Therefore the physical quantity is detected highly accurately at a high SN ratio.

Abstract: PURPOSE:To prevent engine stall and rough idling particularly when the fuel temp. is high, by furnishing a solenoid valve to vary the valve passage on the basis of the fuel temp., and thereby performing fuel supply in accordance with the fuel temp. CONSTITUTION:When the fuel returned through a return pipe has raised the fuel temp. in an in-tank to a point at which vapor is generated, it is sensed by a thermosensor 31 to actuate a solenoid valve 30 with the aid of an electronic control device ECU.
