  • Wheel bearing apparatus
    Patent number: 9527345
    Abstract: A wheel bearing apparatus has an outer member, an inner member and double row rolling elements. A pulser ring is fit onto the inner ring. A second cap is fit on the inboard-side end of the outer member. A rotational speed sensor is mounted on the second cap. A cup-shaped first cap is press-fit into the inner circumference of an inboard-side end of the outer member. The first cap has a cylindrical fitting portion press-fit into the outer member. A disk portion extends radially inward from the fitting portion. The sensor abuts the disk portion. The second cap is press-fit into the inner circumference of an inboard-side end of the outer member via a predetermined interference.
    Type: Grant

  • Laser doping processing method and method for manufacturing semiconductor device
    Patent number: 7504325
    Abstract: It is an object of the present invention to provide an easy doping method where concentration control is easy, where doping with respect to a large area can be practically conducted and which does not require a special device. The present invention provides a laser doping method where a liquid including a dopant is applied to the surface of a semiconductor that is to be doped and the surface of the semiconductor is irradiated with laser light to add the dopant to the semiconductor. It is also possible to conduct crystallization at the same time.
