  • Publication number: 20140256172
    Abstract: A power supplying plug lock device attachable to an operation arm of a power supplying plug, the operation arm operable to fix the power supplying plug to an inlet, is configured to restrict movement of the operation arm to prevent unauthorized removal of the power supplying plug. The power supplying plug lock device is externally attachable to the operation arm when an authentication member accomplishes authentication. A restriction member moves from an open position to a close position to engage with the operation arm when the power supplying plug lock device is attached to the operation arm. A position holding mechanism shifts to a lock state in cooperation with the movement of the restriction member to the close position, thereby holding the restriction member at the close position. The position holding mechanism maintains the lock state until the authentication member again accomplishes authentication.

  • 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.
