    摘要： A communication device and a cryptographic key creation method are provided that enable efficient creation of cryptographic keys of which different error rates are required. A communication device (11) that performs communication with another communication device (12) through a transmission link includes a cryptographic key sharing section (1103) that share a first cryptographic key with the other communication device, an error rate control section (1115, 1105-1108) that creates second cryptographic keys with error rates according to purposes of use of the cryptographic keys from the first cryptographic key, and an accumulation section (111, 1112) that separately accumulates the plurality of second cryptographic keys with the different error rates.

    摘要： In a contact of the present invention, a first plate spring piece portion 11c having a first fulcrum portion 11b in one side extends in a cantilevered manner from the first fulcrum portion 11b in a direction opposite to a card insertion direction so as to be elastically deformable in a thickness direction of the card. A second plate spring piece portion 11e having in one side a second fulcrum portion 11d which is the other side of the first plate spring piece portion 11c is formed in a shape where the second plate spring piece portion extends at an inclination angle from the second fulcrum portion 11d in the card insertion direction so as to be elastically deformable in the card thickness direction. The other side of the second plate spring piece portion 11e is to be contacted with the contact pad 2 of the card 1.

    摘要： An alternator for generating electric power is mounted on an automotive vehicle. The alternator includes a housing, a stator fixed in the housing, a rotor driven by an engine of the automotive vehicle, and electric components such as a brush holder. The brush holder is mounted on a rear surface of a rear frame constituting the housing and is covered with a rear cover fixed to the rear frame. The rear cover includes a surrounding wall covering the brush device to prevent water from reaching a brush area. The surrounding wall is composed of plural partial walls having respective radiuses from a rotational axis of the rotor. The surrounding wall may be continuously made by the partial walls. Alternatively, openings for draining water may be formed in the partial walls positioned downward of the rotational axis of the rotor.

    摘要： A disclosed lens actuator includes: an objective lens condensing a light beam on an optical storage medium; a diffractive element providing compatibility with plural types of optical storage media relative to light sources of plural different wavelengths; and a lens holder including the objective lens and diffractive element in an opposing manner. The objective lens is driven with the lens holder in at least a focusing direction and tracking direction relative to the optical storage medium. At least three protrusions are set on the lens holder in directions orthogonal to an optical axis of the objective lens. The protrusions are in contact with at least one of circumferential surfaces of the objective lens and the diffractive element and position the objective lens or the diffractive element. An end surface of the protrusion in contact with the circumferential surface of the objective lens or the diffractive element has a plane surface.
