  • Patent number: 10295243
    Abstract: A gas supply device is configured such that its supply state is switchable between a first supply state supplying, as supply air, nitrogen-enriched air produced from outside air into a containe, and a second supply state in which the gas supply device takes outside air therein and supplies, as supply air, the outside air into the container. A CA system is provided with a branch pipe which guides at least part of the supply air flowing through a supply passage to an oxygen sensor, and an open/close valve which opens/closes the branch pipe. An outside air calibration operation is performed in which the open/close valve is opened in the second supply state to guide the least part of the outside air flowing through the supply passage to the oxygen sensor, thereby calibrating the oxygen sensor using the outside air.

  • Patent number: 8353227
    Abstract: A structure for sufficiently spacing a steering handle from a top bridge, thereby greatly improving design flexibility. A relief portion for allowing the deformation of a washer is formed to overlap a second contact surface and adjacent to a first contact surface as viewed in the axial direction of each bolt member. The first contact surface is located so as not to overlap the second contact surface as viewed in the axial direction of each bolt member. Therefore, a bending force acts on the washer to allow the deformation of the washer. That is, the washer can exhibit a spring function to relax the effect of the bending force. As a result, the steering handle can be sufficiently spaced from the top bridge to thereby greatly improve design flexibility.
