Title: Supporting structure of output shaft of motor and supporting structure of motor
Inventor: GOTO YASUO
IPC: H02K5/24
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent an influence of reactive force on an output shaft caused by gears joined with the output shaft in a motor. SOLUTION: In a motor unit 10, bearing parts 36 and 38 for a motor 20 have an O-rings 40 and 42 inserted inside for holding the motor 20 in a given position. A gear storing part 32 of a case body 12 has holding parts 50 and 52 projected to a motor output shaft 22. Even when the motor output shaft 22 is bent by reaction force F1 caused from a first gear 34, the motor output shaft 22 is held by the holding parts 50 and 52. In addition, when the reaction force F1 is applied to the motor output shaft 22, the motor 20 is shifted, and thereby the reaction force F1 is absorbed by elastic force of the O-rings 40 and 42. In this way, noised caused by bent or distortion of the motor output shaft 22 or the generation of backward electromotive voltage can be prevented.

Title: Fuel injection device for diesel engine
Inventor: MATSUOKA TAKESHI
IPC: F02M61/20
Filed: 1984-02-01
Abstract: PURPOSE:To aim at improvements in emission performance at an engine's low load range as well as in output of power at a high load range, by using plural fuel discharge passages properly according to an engine load state, while altering a lift control starting position for a needle valve. CONSTITUTION:High pressure fuel enters a fuel injection nozzle 7 from a fuel- injection pump, then enters a fuel pressure chamber 14 from an inlet 9 via a passage 15, and hereat it forcibly presses a pressure receiving part a 6c of a needle valve 16, lifting it against a spring 17 to open the valve, while the fuel in the chamber 14 passes through a fuel nozzle hole 8 and is fed to an engine's combustion chamber. What is more, pressure in the high pressure fuel entered from the inlet 9 passes a plunger member 18 to the needle valve 16 and controls the valve 16. And, at an engine's low load range, such a state that fuel is spouted at high speed from the fuel injection nozzle hole 8 continues to be long enough so that fuel atomization is well accelerated and unburned gas is reduced in a large measure, thus emission performance is improved. In addition, at a high load range, a fuel injection quantity for an engine is well secured, therefore an injection rate is improved, thus improvements in engine output is promotable.

Abstract: PURPOSE:To control electric potential of a substrate freely while showing normal attraction function by providing a substrate of a conductor or a semiconductor substance on a first electrode with an insulator between and by burying a second electrode which provides it with an electric potential in the insulator. CONSTITUTION:An Mo-made first electrode 61 has an outer diameter and an inner diameter of a large circle of 9cm and 6cm, respectively and a diameter of a small circle of 3cm and a space part of an Mo-made second electrode 63 which provides an electric potential to a substrate 64 is about 1mm.

When 1kV is applied in air and a 4 inch wafer is attracted, it is attracted completely by a force of 0.2N/cm or more. It becomes possible to control an electric potential of a substrate surface while making a large current flow through a substrate and to attract the substrate by electrostatic force. It is also resistant to thermal stress and is useful when controlling an electric potential at a positive side from self-bias by plasma and when a substrate of a large area is used.

Title: Substrate for flame-sprayed tile
Inventor: MATSUO MASATAKA
IPC: C04B41/85
Filed: 1988-01-27
Abstract: PURPOSE:To obtain the present substrate resistant to cracking and chipping caused by thermal spalling in the baking of glaze, by forming a surface layer made of fine particles on the surface of a substrate layer produced by dispersing coarse particles in an inorganic matrix. CONSTITUTION:A substrate for a flame-sprayed tile can be produced by dispersing coarse particles 4 having particle size of >=0.5mm in an inorganic matrix 3, using the dispersion as the substrate layer 1 of a flame-sprayed tile substrate material and forming a surface layer 2 composed of fine particles having particle size of <100mum on the surface of the substrate layer. The substrate layer 1 has excellent thermal shock resistance by the presence of the coarse particles 4 dispersed in the substrate material and is covered with a surface layer 2 made of fine particles having excellent smoothness. The stress generated by the local heated of the tile substrate material by flame-spraying burner is absorbed by the coarse particles 4 to prevent the generation of cracking and chipping. Since a glaze layer 5 is formed on the surface layer 2 having low surface roughness, the product produced by this process has excellent smoothness. A flame-spraying tile free from surface unevenness and having excellent quality can be produced by the use of the present substrate material.
