  • Patent number: 5441031
    Abstract: A vent passage communicated to an upper space of a fuel tank mounted on an automobile is connected to a canister. A two-way valve, which includes a pair of one-way valves disposed oppositely and in parallel to each other, is provided in the vent passage. One one-way valve is adjusted its valve opening pressure in a two-staged manner according to the operational state of an internal combustion engine. In another method, a bypass passage bypassing the two-way valve is provided in the vent passage. A solenoid valve and a one-way valve are interposed in the bypass passage. The above one one-way valve of the two-way valve is set at a first valve opening set-up pressure, and the other one-way valve is set at a second valve opening set-up pressure lower than the first valve opening set-up pressure. The solenoid valve is opened or closed according to the operational state of the internal combustion engine.

  • Patent number: 5125685
    Abstract: The present invention relates to a cable reel in which an electrical connection between a fixed body and a movable body is made through a flat cable. The cable reel is suitable for installing on an expandable and contractible steering device of a vehicle, the device having a telescopic function. The cable reel includes the fixed body, the movable body rotatably attached to the fixed body, and the flat cable which is housed between the fixed body and the movable body while being wound around, and a storage housing having a pair of retaining bodies which are relatively and slidably connected to each other. Both the ends of the flat cable are electrically connected to the outsides of the fixed body and the movable body, respectively. The flat cable led out of the fixed body is affixed to the retaining bodies, respectively, and is curved in a semi-loop-like shape between fixed sections.

  • Patent number: 4945740
    Abstract: A vehicle steering lock device mounted to an automotive vehicle, in which a rotor in a cylinder lock is rotated to a lock position by the operation relevant to the rotor, comprises switching means for detecting a specific pushing operation to the rotor, etc. and switching means for detecting the situation of a shift lever to a parking position or not, in which rotation of the rotor to the locking position is allowed or inhibited in accordance with signals from both of the switching means and which enable safe parking on a downward slope and can prevent erroneous steering lock operation during down hill running without engine driving.
