  • Patent number: 11945377
    Abstract: A vehicle exterior part includes a decorative body, a heater sheet, a connector pin. The decorative body includes a base material, and a transparent resin layer. The heater sheet includes a heat generating body, and an extending portion. A part of the heater wire in the extending portion is joined to the connector pin inside an outer periphery of the base material by a joining portion made of a conductive material. The outer periphery is formed with a window configured to join the heater wire to the connector pin by the joining portion in a state where a joining position is exposed to an outside of the outer periphery. The window is provided with a waterstop portion configured to restrict water from entering the joining position. The waterstop portion is formed by filling the window with a potting material.

  • Patent number: 8901874
    Abstract: An electric power steering system calculates a motor resistance Rm using a resistance map, and calculates an estimated inducted voltage based on a motor current and a motor voltage. If the estimated induced voltage is determined as being equal to or smaller than a determination value that is set in accordance with the current level, the electric power steering system calculates a motor resistance (estimated motor resistance Rma) and updates the resistance map based on the estimated motor resistance Rma.

  • Patent number: 8823305
    Abstract: In an electric power steering system, a back electromotive force constant is calculated on the basis of a steering angular velocity and an estimated induced voltage. Then, a rotation angular velocity of a motor is calculated as an estimated rotation angular velocity on the basis of a motor current, a motor voltage, the back electromotive force constant and a motor resistance.

  • Patent number: 8306647
    Abstract: In a flexible manufacturing system, a control apparatus for a transfer device stores in a memory section thereof correlation information for correlating workpieces (ante-machining workpieces) to be attached to pallets with blank materials contained in blank material baskets. When a selected one of the pallets is to be transferred to a pallet loading station, the control apparatus determines blank materials corresponding to the workpieces to be attached to the selected one of the pallets based on the correlation information and then, controls the transfer device to transfer a blank material basket containing the determined blank materials from a basket rack to a basket loading station located adjacent to the pallet loading station in connection with transferring the selected one of the pallets to the pallet loading station. Thus, when the selected one of the pallets is transferred to the pallet loading station, it becomes possible to reduce the time taken for the worker to search for the blank material basket.
