Abstract: Provided is a linear solenoid valve having at least one notch that opens on an end surface of the land of the spool on the drain chamber side and is formed on an outer peripheral surface of the land. In response to movement of the spool, a state is formed in which the end surface of the land on the drain chamber side is located inside the communication chamber and the output chamber and the drain chamber communicate with each other via the notch and the communication chamber, and a state is formed in which the end surface of the land on the drain chamber side is located inside the output chamber and the output chamber and the drain chamber communicate with each other via the communication chamber.

Abstract: An information acquiring section acquires identification information recorded in a card. A behavior DB stores a kind-of-card ID, and software associated with the kind-of-card ID. A processing section, when the identification information is acquired by the information acquiring section, specifies software associated with a kind of card by referring to storage contents of the behavior DB. Incidentally, the behavior DB stores the kind-of-card ID and processing for software with the kind-of-card ID and the processing being associated with each other. The processing section executes the processing stored in the behavior DB for the specified software.

Abstract: An electromagnetic valve for a transmission-use oil pressure control device including an oil pump that supplies oil pressure to a transmission, and an accumulator that accumulates an oil pressure generated by the oil pump. The electromagnetic valve includes: an electromagnetic valve main body connected to the accumulator and includes an oil path opening/closing valve element opening/closing an oil path between the accumulator and the transmission; a seal member disposed in the electromagnetic valve main body sealing against oil leakage from a sliding portion of the oil path opening/closing valve element in the opening/closing operation of the oil path opening/closing valve element; and a pressure regulation mechanism disposed in the electromagnetic valve main body regulating to release an internal pressure in the accumulator when an accumulator-side oil pressure in the electromagnetic valve main body rises to a predetermined pressure or more.

Abstract: A vehicle drive apparatus for supplying oil pressure to a hydraulic servo at restart of an engine. The vehicle drive apparatus includes an accumulator that accumulates the oil pressure, an electromagnetic switching valve that retains oil pressure of the accumulator when an oil pump is stopped, a switching valve control unit that controls opening and closing of the electromagnetic switching valve, and a restart determining unit that determines whether or not to restart the vehicle drive source from a stopped state. When it is determined by the restart determining unit to restart the vehicle drive source, the switching valve control unit is started so as to supply the oil pressure accumulated in the accumulator to the hydraulic servo. As a result, engine friction engagement elements are quickly engaged to enable starting of a vehicle.
