  • Patent number: 6723941
    Abstract: In the wire electric-discharge machining apparatus, when a measured voltage exceeds a proportional constant switching voltage that is set higher than a short circuit reference voltage, a relative feed rate determining unit outputs a relative feed rate based on a preliminarily set proportional constant A according to an increase in the measured voltage. When the measured voltage is equal to a reference voltage, the relative feed rate determining unit outputs a target feed rate that becomes a target value, and also outputs a relative feed rate that follows a preset proportional constant B (<A) and that is a positive value when the measured voltage exceeds the short circuit reference voltage but is below the proportional constant switching voltage.

    Abstract: A method for fixing and a structure for fixing a bearing member for a cylindrical substrate, a print cartridge and an apparatus for forming an image are provided, in which the deflection precision of the cylindrical substrate, such as an electrophotographic photoreceptor, is improved. A cylindrical substrate is expanded toward the outer periphery based on the expanding function caused by elasticity of a first inserting member and a second inserting member upon inserting into the cylindrical substrate from ends of the cylindrical substrate, so as to clamp the cylindrical member and bearing members interdigitated on the outer periphery of the cylindrical substrate. A second inserting member is inserted into the first inserting member.
