Patents by Inventor Hisashi YABUKI

Hisashi YABUKI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.

  • Patent number: 10336270
    Abstract: A vehicle and a manufacturing method thereof is provided in which separation of positively charged airflow from a positively charged surface of a vehicle body can be prevented. A vehicle body is insulated from a road surface, and positive static charges accumulate on the vehicle body during propulsion. The vehicle comprises a self-discharge device that is adapted to decrease a positive potential of at least any one of specific points at which positively charged airflow flowing along a vehicle surface deviates therefrom, during propulsion of the vehicle, by discharging static electricity to produce negative ions according to the positive potential of the specific point.
