  • Patent number: 10174860
    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.

  • Patent number: 8028028
    Abstract: A message string output system which can prevent users from feeling uncomfortable due to repeated input of a particular string by another user is provided. A judging unit (36) judges whether or not a message string which is input by an input unit (30) contains a specific string. An input status information updating unit (38) updates, based on a judgment result by the judging unit (36), input status information stored in an input status information storage (46) in corresponding to user identification information corresponding to the message string. An output form determining unit (43) determines an output form of a specific string part contained in the message string based on the input status information stored in correspondence with the user identification information corresponding to the message string.

  • Patent number: 7552615
    Abstract: A failure detection device for detecting a failure of a rotation angle detection sensor, which sensor detects a rotational angle through which a rotary member has rotated, the failure detection device including a first detection element which has an output which increases as the rotational angle of the rotary member increases, a second detection element which has an output that decreases as the rotational angle of the rotary member increases, and a detecting unit that detects the failure of either the first detection element or the second detection element by comparing a calculated value, based on the outputs of both of the first and second detection elements, with at least one predetermined value.

  • Publication number: 20090054158
    Abstract: There is provided a game system capable of appropriately evaluating whether or not a game advertisement has been recognized by a player. An advertisement evaluation information storage unit (80) stores advertisement evaluation information representing an evaluation about outputting an advertisement. An advertisement output unit (72) outputs the advertisement. An output status determining unit (74) determines whether or not an output status of the advertisement satisfies a predetermined output status criterion. A game item selection accepting unit (68) accepts selection of a game item. A selection content determining unit (76) determines whether or not the selection of the game item corresponding to the advertisement has been accepted.

  • Patent number: 7261603
    Abstract: The connector includes a connector housing having two terminal fittings and terminal receiving chambers for receiving the terminal fittings, and a spacer 4 to be inserted into the connector housing through an opening. A receptacle for inserting an unlocking jig is formed on the spacer. The receptacle is opened at an outer wall of the spacer and a boundary wall to the connector housing 3. The receptacle is disposed in a manner not to spread across two terminal-receiving chambers. The receptacle communicates with one of the terminal-receiving chambers. A block of a main body of the spacer blocks a path between the receptacle and the other terminal-receiving chamber.
