    摘要: A vacuum valve includes a hermetically sealed vessel having an insulative cylinder, an end plate at a movable electrode end, and an end plate at a fixed electrode end. The vessel accommodates a movable contact and an opposed fixed contact. The movable contact is supported through a bellows allowing the contacts to open and close while maintaining an air-tight (hermetic) seal. The bellows used in at least one embodiment is a seam type bellows without metal plating. Nickel plating layers are formed on the end plate at movable contact end and on a cover, which are joined to the bellows. The ends of the bellows are soldered with the end plate and the cover using a silver solder at the solder joints.

    摘要: A scanner device includes a scanner body enclosed by a housing and an external cover covering an outer side of the housing. The external cover is comprised of a plurality of external members. By spacing the adjacent external members apart from each other at the side edge parts of the housing, recesses are formed between the adjacent external members so as to constitute parts of the external design of the scanner body. Preferably, the side edge parts of the housing are exposed between the adjacent external members at the side edge parts of the housing, and information providing devices providing information on the scanner device are provided at the side edge parts of the housing exposed between the adjacent external members.

    摘要: An optical transmission system includes an optical wavelength branching unit that shifts a wavelength transmission band in the short-wavelength or long-wavelength directions based on a branching filter operation temperature, and performs a branching operation on a wavelength-multiplexed signal. A reception transponder performs decoding on an error correction code. An error correction monitoring unit gathers an error correction amount upon which a branching filter temperature control unit sets the branching filter operation temperature. A transmission transponder performs encoding on an error correction code. An optical wavelength combining unit shifts the wavelength transmission band in the opposite direction from the shifting direction based on a combining filter operation temperature, to perform a combining operation on optical signals and output a wavelength-multiplexed optical signal. A combining filter temperature control unit sets the combining filter operation temperature based on the error correction amount sent from the optical reception device.
