  • Publication number: 20190283207
    Abstract: A screw rotor lead correction calculation device includes an initial data input section configured to input an error as a distance with respect to a reference lead at each axial position of a rotor groove portion of a screw rotor, and a processing machine input correction amount/position output section configured to compute and output, based on the error as the distance input to the initial data input section, a lead correction amount with respect to the reference lead and a lead correction starting position as an axial position for starting lead correction. With this configuration, correction data for obtaining a screw rotor with a high-accuracy lead can be obtained from a lead error with respect to a reference lead in a screw rotor obtained by ground finish of the material of the screw rotor.

  • Patent number: 10384663
    Abstract: Provided is a vehicle electrification charge reducing apparatus, including: a steering operating device, a steering actuator; and a displacement transmitting system configured to transmit a displacement of the steering operating device to the steering actuator. At least one of the steering operating device, the steering actuator, or the displacement transmitting system includes two members that are engaged with each other through intermediation of a viscous lubricant agent so as to move relatively when the steering operating device is operated. A self-discharge type charge eliminator is fixed to a surface of a specific member forming the displacement transmitting system and the like, and the self-discharge type charge eliminator diselectrifies the specific member through self-discharge so as to decrease a charge amount of the specific member, to thereby decrease a difference in charge amount between the two members.
