  • Publication number: 20120064236
    Abstract: The present invention has been aimed to propose a process and a device of fabricating a prepreg for a printed circuit board which are capable of controlling respective thicknesses of resin layers on the opposite surfaces of a resultant prepreg, removing air bubbles from the resultant prepreg, and improving productivity. The present invention is a process of resin-coating the opposite surfaces of an elongated substrate sheet 3. The process includes the steps of: feeding the substrate sheet 3 while tensioning the same in a feeding direction along the length of the substrate sheet 3; coating, by the coating head 2 of the first dispenser 1a, one surface of the substrate sheet 3 with the fluid resin 4 while pressing against the one surface to bend the substrate sheet 3; and subsequently coating, by the coating head 2 of the second dispenser 1b, the other surface of the substrate sheet 3 with the fluid resin 4 while pressing against the other surface to bend the substrate sheet 3.

  • Patent number: 7768175
    Abstract: A manufacturing method for a brush that can reduce contact surface area between a commutator and the brush, thereby reducing frictional noise, is provided. Specifically, a method to manufacture a brush, which provides one surface with contact surfaces that make sliding contact with the commutator, involves a step to mold a molded body and a step to cut the molded body. In the molding process, carbon powder containing copper powder is sintered to form a molded body having a groove on the top surface along the direction of the axis of rotation of the commutator, and curved surface margins in the margins of the top surface in the direction of the axis of rotation. In the cutting step, the central part of the top surface of the molded body is cut by a grinding stone along the cutting direction to form contact surfaces between the margins of the top surface.

  • Patent number: 7051834
    Abstract: In a power steering apparatus, a basic-target-rotational-speed setting portion 42 sets a basic target rotational speed Rb of an electric motor 27 on the basis of the vehicle speed and the angular velocity of steering. A temperature-coefficient setting portion 43 sets a temperature coefficient a which becomes smaller with an increase in the temperature. A target-rotational-speed setting portion 44 sets a target rotational speed R of the electric motor 27 on the basis of the formula R=?·Rb. A motor-drive control portion 45 controls a drive circuit 28 so that this target rotational speed R will be attained.
