  • Patent number: 7798462
    Abstract: A sliding-type automobile seat comprising a seat cushion frame, a slide rail mechanism for allowing the seat to be slidingly moved, slide lock mechanisms for causing the seat to be releasably locked at predetermined positions, a substantially U-shaped operating lever for causing the seat to be released from a locked state, and connection mechanisms for causing both end portions of the substantially U-shaped operating lever to the slide lock mechanisms, the slide rail mechanism comprising a pair of parallel lower rails mounted on a floor surface of an automobile, and a pair of parallel upper rails attached to a lower portion of the seat cushion frame and slidably engaged with the pair of parallel lower rails, each of the slide lock mechanisms comprising a lock member swingably mounted to a corresponding upper rail and urged upward at one end portion thereof by a spring, the lock member including a first engaging member, and a second engaging member provided at a corresponding lower rail, the first engaging mem

  • Patent number: 7394330
    Abstract: A magnetic rotor includes a soft ferrite substrate and a plurality of central conductors. The magnetic rotor is provided inside a casing. A permanent magnet is provided inside the casing, and disposed to overlap the magnetic rotor so as to apply a DC magnetic field to the magnetic rotor. The casing includes a magnetic metal material. The casing is coupled with the permanent magnet so as to form a yoke. A coupling portion is formed in a direction crossing a magnetic circuit of the yoke. The casing is coupled in a direction of the magnetic circuit through the coupling portion. The coupling portion includes a single plate capacitor having a high impedance in response to a DC current and has low impedance in response to a high frequency current.
