Tomohiko Kawaguchi 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: 11421467
    Abstract: An opening-closing body controller includes a motor body that opens and closes an open-close body, a control unit that controls and drives the motor body, and an inner temperature detector that detects an inner temperature of the motor body. The control unit performs an entrapment detection process in a section excluding a mask section that is set from a fully closed position of the open-close body to a preset position in an opening direction of the open-close body. The control unit corrects the mask section in accordance with the inner temperature of the motor body detected by the inner temperature detector.

  • Publication number: 20190337366
    Abstract: An opening-closing body drive device includes a motor that opens and closes an opening-closing body; and a controller that controls driving of the motor. The controller recognizes an arrested position of the motor during a closing action as a reference position and performs an entrapment process in a section excluding a mask section from the reference position to a predetermined position toward an opening direction side. The controller updates the reference position when the arrested position of the motor is located toward a closing direction side of a set position, which is set in the mask section, and does not update the reference position when the arrested position of the motor is located toward an opening direction side of the set position.

  • Patent number: 10464399
    Abstract: A vehicle window opening device includes a controller, a change detector, and a drawing detector. The controller configured to control opening and closing of a vehicle window based on a drive force of a motor. The change detector is configured to detect a change in a state of movement of the vehicle window. A drawing detector is configured to detect drawing of a foreign matter by the vehicle window based on a change detected by the change detector. The controller is configured to restrict opening of the vehicle window after the drawing detection.

  • Patent number: 7206190
    Abstract: In an electrode for an electric double layer capacitor of the present invention, the peak value of particle size distribution of graphite particles added to a conductive adhesive is in a range of 2.6 to 3.2 ?m, not less than 100,000 dimples having a largest outer diameter in a range of 4 to 10 ?m and a depth in a range of 4 to 15 ?m are formed on the surface of the collector sheet per 1 cm2, and the occupied area of the dimples to the entire surface area of the collector sheet is not more than 50%. By determining the saponification value of polyvinylalcohol which is used as a binder component of the conductive adhesive in a range of 90.0 to 98.5, adhesiveness of the collector sheet and the electrode forming sheet is improved. Furthermore, by substituting H atoms contained in the polyvinylalcohol with Si atoms, adhesiveness of the collector sheet and the electrode forming sheet can be further improved.
