Yuichi Nanae 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).

  • Moving apparatus with drive force assist mechanism and movement control method
    Patent number: 6580188
    Abstract: A moving apparatus with a driving force assist mechanism traveled mainly by human power. This moving apparatus detects, in a non-contact manner, with respect to rotating portion such as traveling wheel, etc., rotation speed of the rotating portion to detect traveling state to deliver, from the driving force assist mechanism, assistant driving force corresponding to speed change information that a person who operates the moving apparatus intends to give on the basis of the detected traveling information to carry out traveling to thereby permit smooth traveling even in the case where traveling by only human power becomes difficult.
    Type: Grant
    Filed: May 9, 2001
    Date of Patent: June 17, 2003
    Assignee: Sony Corporation

  • Iron core motor device
    Patent number: 5754025
    Abstract: An iron motor device includes an iron core motor the rotor of which is rotationally driven a pre-set angle by electromagnetic induction responsive to phase switching of current supply to two-phase coils wound on an iron core, and a driving control unit for generating a driving control signal based on the phase information of differentially phased backward voltages induced in the two-phase coils. The driving control unit causes shorting of the backward voltage induced in the coil the current supply in which is interrupted by phase switching of current supply to the two-phase coils by providing a pre-set time delay in the turn-off timing of the switching device connected to the coil the current conduction in which is interrupted. The method for drive controlling the iron core motor device is also disclosed.
