  • Method for the single-sided polishing of bare semiconductor wafers
    Publication number: 20080305722
    Abstract: Single-sided polishing of bare semiconductor wafers is accomplished by using a polishing head with a membrane made of a resilient material by which polishing pressure is transmitted onto the backside of the semiconductor wafer to be polished, wherein the semiconductor wafer is pressed against a polishing cloth with a smooth surface while supplying a polishing agent, and is prevented from sliding off the membrane by a retainer ring. The retainer ring is provided with channels on a side surface facing the polishing cloth.

  • Mop
    Patent number: 6253408
    Abstract: A mop to be fastened at the end of a mop handle, including a holding device to which a number of relatively mobile, absorbent strips made of a textile material are fixed essentially transversely to the axis of the handle. At least one spring body is provided, which causes the strips to spread apart, at least in the region of the holding device.

  • Insulated dynamo windings
    Patent number: 4908535
    Abstract: The commutating poles of vehicular-type dc motors, for example for trolley buses or trolley cars, are made by winding, on edge, a copper strip, permitting the wound copper strip to resiliently, spring-like expand so that the individual spiral loops thereof will be slightly spaced from each other, and then exposing the copper strip in a fluidized bed to an insulating powder, for example polyethylene or polyurethane, which is subsequently cured in a hardening or sintering process.
    Type: Grant
    Filed: October 26, 1988
    Date of Patent: March 13, 1990
    Assignee: Robert Bosch GmbH
    Inventors: Helmut Kreuzer, Klaus-Peter Meier
  • Direct-current dynamo electric machine, and method of manufacture
    Patent number: 4782254
    Abstract: The commutating poles of vehicular-type d-c motors, for example for trolley buses or trolley cars, are made by winding, on edge, a copper strip, permitting the wound copper strip to resiliently, spring-like expand so that the individual spiral loops thereof will be slightly spaced from each other, and then exposing the copper strip in a fluidized bed to an insulating powder, for example polyethylene or polyurethane, which is subsequently cured in a hardening or sintering process.
