  • Publication number: 20170225575
    Abstract: A charging device is for an electric moving body, which is compatible with multiple charging protocols having different settings for voltage, current. The vehicle charging device is provided with: a CHAdeMO control unit and a combined-charging control unit for performing battery charging control on the basis of the CHAdeMO protocol and the combined-charging protocol; power conversion systems (PCS) which are connected in parallel and convert alternating-current power into direct-current power; power-feeding connectors which connect to a power-receiving connector disposed in the vehicle; and a switching unit for setting a connection between the output of the PCSs and the power-feeding connectors. The switching unit performs settings such that when one vehicle is to be charged, the PCSs are connected to the battery of this vehicle, or when two vehicles are to be charged, the PCSs are respectively connected to the batteries of these vehicles.

  • Patent number: 9435982
    Abstract: According to one embodiment, a focus position changing apparatus is provided on an optical path of a confocal optical apparatus having a light source and an objective lens and is configured to change a focus position of the objective lens in an optical axis direction of the objective lens. The focus position changing apparatus includes at least a plurality of optical path changing pieces and a rotating plate. Each of the plurality of optical path changing pieces is differ from each other in at least one of a refractive index and a thickness. On the rotating plate, the plurality of optical path changing pieces is arranged along a rotation direction of the rotating plate so as to cross an optical axis of the objective lens. And an anti-reflection layer is formed in a predetermined region on a surface of the rotating plate on a side of the light source.

  • Patent number: 9341469
    Abstract: A continuous scan type measuring apparatus includes a continuous scan type optical application measuring instrument, a single-axis measuring instrument scanning stage and two carrier stages. The continuous scan type optical application measuring instrument performs a surface shape measurement of a measuring object. The single-axis measuring instrument scanning stage carries the optical application measuring instrument and causes the optical application measuring instrument to perform continuous scanning along a predetermined direction. The two carrier stages are detachably mount respective measuring objects thereon and move independently of each other. The two carrier stages are positioned independently at one of a measurement position within a scanning range of the optical application measuring instrument and a replacement position of the measuring objects.

  • Patent number: 9041940
    Abstract: According to one embodiment, a three-dimensional shape measuring apparatus includes at least an aperture plate that is provided with a plurality of confocal apertures which are two-dimensionally arranged to have a predetermined arrangement period, and an aperture plate displacement portion that displaces the aperture plate at a constant speed in a predetermined direction perpendicular to the optical axis direction. Further, the aperture plate is provided with a cover member which is moved integrally with the aperture plate and which includes a transparent body allowing the light beams from the light source to pass therethrough and to be irradiated to the plurality of confocal apertures, and protects the plurality of confocal apertures from dust. Further, an imaging optical system, by which each of reflected light beams is guided to a photo-detector, is designed in consideration of optical properties of the whole optical system including the transparent body of the cover member.
