摘要:
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.

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. A die coater and a roll coater can be used as the first dispenser 1a and the second dispenser 1b.
