  • Patent number: 10101264
    Abstract: This invention is a multiple reflection type cell that makes it possible to reduce a dead space resulting from a position adjusting mechanism and to adjust the light to a desired optical path length without complicating a structure. The multiple reflection type cell comprises a cell body where a cell chamber is formed, two or more reflecting members that are mounted on the cell body and whose reflecting surfaces locate in the cell chamber, and a position adjusting mechanism that adjusts a position of the reflecting member relative to the cell body. The cell body has a mounting part that communicates the cell chamber and the outside and on which the reflecting members are mounted. A seal member that seals a gap between the cell chamber and the outside of the cell body is arranged between the reflecting member mounted on the mounting part and the cell body so that the gap between the cell chamber and the outsider of the cell body is sealed by the seal member.

  • Patent number: 9116106
    Abstract: The X-ray detection apparatus is equipped with an X-ray irradiation unit, an X-ray detector, and a movable collimator having a plurality of apertures. The collimator is provided with a window unit through which light passes, and the apertures and the window unit are aligned in one direction. The collimator moves in the direction so as to change the diameter of an aperture for narrowing X-rays from the X-ray irradiation unit to be used for irradiation of a sample and move to a position to allow an imaging unit to photograph a sample through the window unit. It becomes possible to photograph a sample even in a state where the X-ray irradiation unit, the X-ray detector and the collimator are positioned proximally to each other.

  • Publication number: 20120062936
    Abstract: A printer includes an output unit, a management unit, and a transmission unit. The output unit outputs an image onto print paper. The management unit monitors an operating state of the output unit, and manages operating state information. The transmission unit transmits managed operating state information in response to an operating state acquisition request from a host device. Upon receipt of a request for obtaining operating state information from the host device, if the printer is set as a first device in tandem operation, the transmission unit does not transmit the operating state information to the host device. If the printer is set as a second device in tandem operation, the transmission unit transmits the managed operating state information including operating state information on the printer and operating state information on the first device to the host device.
