Abstract: A box device includes a box body having a housing portion with an upper opening, and a front movable member and a rear movable member slidably disposed in front and rear directions in the box body for opening and closing the upper opening of the housing portion. The box device further includes a first guide portion engaging the front movable member for guiding the front movable member to slide in the front and rear directions; a second guide portion engaging the rear movable member for guiding the rear movable member to slide in the front and rear directions; and an engaging device for connecting and disconnecting the front movable member and the rear movable member.

Abstract: A cup holder has a case fixed to a conveyance, a tray for supporting the bottom of a container, and a pair of left and right holders. The case has an aperture open toward a passenger compartment. The tray is movably supported by the case, and can be pulled out from a storage position in the tray to a usage position, via the aperture. Each holder has an arm with a ring for supporting the side of the container. The arms are linked to the tray so as to be able to rotate horizontally. Each ring has an overlapping part that vertically overlaps with the other ring when the arms approach each other, and a non-overlapping part that does not overlap when the arms approach each other. The vertical-direction width of the overlapping parts is smaller than the width of the non-overlappng parts, thereby reducing the vertical-direction width of the case, making the holder suitable for installation in a conveyance having only limited usable space.

Abstract: A method and apparatus for detecting an abnormal condition of a switch gear device including a switch gear, for instance a circuit breaker driven by an operating device. A device for detecting the operating force applied from the operating device to the circuit breaker is mounted between the operating device and the circuit breaker. Data is obtained from the detecting device, expanded in time for analysis, and compared with data obtained under a normal state to judge the presence or absence of an abnormal condition within the switch gear.
