Title: Push-button switch
Inventor: NAGATOMO YASUSHI
IPC: H01H13/52
Filed: 1994-02-10
Abstract: PURPOSE:To provide a thin and excellent switch by setting a key top pushing- down time stroke as a stroke at which a cup rubber is contracted by reversal operation and a slidingly movable stroke to a key lever while bending a returning coil spring by a key top. CONSTITUTION:When a key top 6 is pressed against a returning coil spring 7, since a stem 6a is supported with a slidingly movable cylinder part 5a of a key lever 5, the key top is not inclined. Next, a cup rubber 8 is reversibly pressed through the lever 5, and a contact point and a membrance contact point 3 contact with the rubber 8, and a switch is closed. In this constitution, since a key top pushing-down stroke becomes a contractile stroke of the cup rubber and a key top stroke, an effective stroke becomes long. Thereby, thinning becomes possible, and an excellent push-button switch which does not cause a sense of incompatibility or an obstacle to an operator is formed.

Title: Throttle valve driving mechanism for internal combustion engine
Inventor: UEDA KATSUNORI
IPC: F02D29/02
Filed: 1990-02-19
Abstract: PURPOSE:To prevent an acceleration feeling of a depressing amount or more of an accelerator pedal by providing an electric motor-driven torque limiting means, in which torque is limited to a torque range not possible to overcome the second return spring but possible to overcome the first return spring, in a throttle valve control means. CONSTITUTION:In the case of a throttle valve 2 open/close driven by an electric motor 10 by placing the throttle valve 2 in a condition that it is opened to a certain degree by depressing an accelerattor pedal 3 by a driver, torque of the electric motor 10 is controlled such that the torque is weaker than a return amount of a stopper 5 by the second return spring 8 and stronger than return force of the throttle valve 2 by the first return spring 6. Consequently, the throttle valve 2 can be freely opened and closed in a step-in range of the accelerator pedal 3 by the electric motor 10, but the throttle valve 2 is prevented from opening more beyond a position of the stopper 5 even when the electric motor 10 tends to be driven by mistake in an opening direction by the step-in range or more.

Title: Socket welding piping fitting
Inventor: MIYATA KOICHI
IPC: F16L13/06
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To reduce high tensile residual stress at a weld root to prevent high- temperature cracking produced at the root by removing the outer circumferential surface of the end of a socket near a weld zone after welding a piping to the socket. SOLUTION: When pipings 2 are connected by inserting the piping 2 into a socket 3 and welding the piping to the socket 3 by weld metal 4, high tensile residual stress may be produced in particular at the weld root of the weld metal 4 by the heat of the weld medal 4. Since the stiffness of the socket is reduced and a gap is closed by removing the outer circumferential surface 13 (corner) of the end of the socket 3 by a grindstone 14 after welding, compressive stress is applied on the part suffering the high tensile residual stress to reduce the high tensile residual stress at the weld root, which prevents high temperature cracking from being produced or expanded.

Title: Dc brushless motor
Inventor: ONO HIROTOSHI
IPC: H02K29/14
Filed: 1985-02-27
Abstract: PURPOSE:To simplify the structure by using a torque ripple correcting magnetic field generating material also as a speed detector of a magnet rotor, and applying a torque ripple correcting magnetic flux generated therefrom to a torque detecting Hall element. CONSTITUTION:A feedback voltage Vt' is added by an adder A to a command voltage Vt input externally, amplified by an amplifier G to obtain a motor drive current I, thereby driving a motor phi. The motor drive current I is converted by a stator coil current conversion block K to a current I'=I.K (K is a constant) proportional to the current I. The magnetic flux coefficient phi' input from a magnet Vmt for correcting a torque ripple to a Hall element H3 is multiplied by the current I' to output a voltage designated by Vt'=I'.phi', and fed back to an adder A to form a motor torque detecting feedback loop. The magnet Mvt is used also for detecting the speed of the magnet rotor. Thus, it can prevent the torque from varying with a simple structure.

Title: Image forming device
Inventor: ISHIDA HIDEKI
IPC: G03G15/08
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device simplified in constitution for positioning a developing roller on a photoreceptor drum. SOLUTION: Regulating rollers 135 and 136 attached to a developing roller shaft 128 are abutted on bearings 126 and 127 respectively, while being supported by the slope 142 of a guiding part formed on a drum unit side plate for holding the photoreceptor drum and the developing roller. Thus, a force F exerted on the developing roller shaft 128, when rotational force is transmitted to the developing roller is resolved into a force f1 in a direction perpendicular to the supporting surface 142 and a force f2 in the direction parallel with the supporting surface 142. Since the force f2 in the direction parallel with the supporting surface 142 is of a force toward the bearings 126 and 127 from the regulating rollers 135 and 136, the regulating rollers 135 and 136 are pressed on the bearings 126 and 127 by the force f2 respectively.  Therefore, an energizing means for engaging the developing roller toward the photoreceptor drum and required in a conventional device is unnecessitated.
