    摘要: A power steering apparatus which generates a steering assist force by a hydraulic pressure of a pump driven by an electric motor. The apparatus includes: an electric current sensor for sensing an electric current flowing through the electric motor; and a control circuit for switching a voltage to be applied to the electric motor from a standby voltage to an assist voltage if the motor current is higher than a first threshold or if a change rate of the motor current is higher than a second threshold.

    摘要: Hot rolled steel plate having an absolute warp value of less than 20mm for a 3m length of cut plate and not subjected to deterioration of mechanical properties, is formed by subjecting steel strip from a hot rolled coil to a strong cold leveling to provide a maximum surface strain .epsilon. max within the range of 0.60% .ltoreq. .epsilon. max .ltoreq. 3.0%. The steel strip may then be subjected to a light cold leveling for slowly diminishing the surface strain. Further, after the straightening or leveling operation the plates are inspected, coated with a rust preventative, marked with identifying indicia and directed to a piling device. The inventive and novel method and apparatus of the present invention for manufacturing thick steel plate from hot rolled coil, which has not been previously successful, is extraordinarily excellent in amelioration of productivity compared with any of the conventional thick steel plate producing methods.

    摘要: A method of manufacturing golf balls having a highly transparent cover includes, prior to formation of the cover, a preformed body fabricating step wherein a fluorescent material that emits light when exposed to ultraviolet radiation is included in or coated onto the preformed body. In this way, a preformed body which matches a cover to be formed can be easily and reliably identified from among a plurality of types of preformed bodies stored at a temporary storage place. This manufacturing method enables golf balls of excellent visibility and stylishness to be efficiently produced.

    摘要: The invention provides damping techniques for a rotating shaft. The rotating shaft is supported by rotary bearings. The damping techniques control vibration of the rotating shaft by creating a fluid film in a support element of the rotating shaft. For example, the fluid film may be created between a housing and the rotary bearings. The fluid may be supplied by a pump, and the supply amount of fluid to create the fluid film is relative to the rotational velocity of the shaft. Vibration can be prevented for every operational rotational velocity of the rotating shaft. In some embodiments, the rotating shaft may be powered by or part of an electric motor for a vehicle.

    摘要: A drive unit is provided for driving a wheel installed on a vehicle. The drive unit includes a driving source equipped with a rotary shaft. A speed reducer is connected between the driving source and the wheel so as to reduce the rotational speed of the rotary shaft and transmit the reduced rotational speed to the wheel. A brake unit is provided having a rotary member rotationally connected to the speed reducer on a side of the speed reducer opposite from the wheel so as to brake the rotation of the wheel through the speed reducer.
