  • Publication number: 20130069628
    Abstract: Disclosed is an optical fibre birefringence compensation mirror. Also disclosed is a current sensor wherein vibration resistance has been increased due to the optical connection of the optical fibre birefringence compensation mirror. The optical fibre birefringence compensation mirror includes: an optical fibre, a birefringence element, a lens, a magnet, a Faraday rotator, and a mirror. From the light incidence/emission end surface of the optical fibre, the birefringence element, Faraday rotator, and mirror are arranged in said order. Light comes in from the optical fibre, and is separated into two linearly polarised lights by the birefringence element. The polarisation planes of the two linearly polarised lights are rotated by the Faraday rotator, and the two linearly polarised lights are point-symmetrically reflected at one point by the mirror, then again rotated by the Faraday rotator, then re-combined into one light by the birefringence element and made to enter the optical fibre.

  • Patent number: 8380380
    Abstract: A secondary self-resonant coil is installed at substantially the central region of the bottom face of the vehicle body, receiving electric power from a power feeding apparatus in a non-contact manner by resonating with a primary self-resonant coil of a power feeding apparatus provided external to the vehicle, via an electromagnetic field. In a power reception mode from the power feeding apparatus, high voltage is generated at the wire end of the secondary self-resonant coil, causing generation of a high electric field around the wire end. In order to keep the wire end distant from an ECU that is an electric apparatus located closest to the secondary self-resonant coil, the secondary self-resonant coil is arranged such that the wire end is located at a side opposite to the side where the ECU is deviated relative to the bilateral symmetric axis of the vehicle body.

  • Publication number: 20120133326
    Abstract: A charging system includes a locking device locking a connector provided at the end of a cable in the state where the connector is connected to an inlet provided in a vehicle; a release button for releasing locking by the locking device; a switch generating a signal indicating that the connector and the inlet are connected; a horn; and an ECU. In response to the operation of the release button, the switch stops generation of the signal. The ECU controls charging of a power storage device and detects whether the signal is issued or not. In the case where the ECU detects that generation of the signal is stopped during charging of the power storage device, the ECU causes the horn to issue an alarm.

  • Publication number: 20120098330
    Abstract: In a noncontact electric power feeding system by means of a resonance method, an electric power receiving apparatus includes a plurality of secondary self-resonant coils. The noncontact electric power feeding system makes a switch between these secondary self-resonant coils to detect a distance between the electric power receiving apparatus and an electric power transmitting unit, and selects, according to distance L as detected, a secondary self-resonant coil with high transfer efficiency for receiving electric power to accordingly feed electric power. In this way, distance L between the power receiving apparatus and the power transmitting unit can be precisely detected including distances from longer ones to shorter ones, and the transmission efficiency in transmitting electric power in a noncontact manner by means of the resonance method can be improved.
