    摘要： An X-ray CT system includes a fixed frame portion and a rotating frame portion. Being provided with X-ray tubes, the rotating frame portion is arranged so as to rotate with respect to the fixed frame portion. Vane members for feeding air are secured on the rotating frame portion. In operation, with the rotation of the vane members together with the rotating frame portion, cool air is introduced into the rotating frame portion. Consequently, heated instruments, such as the X-ray tubes, in the rotating frame can be cooled down effectively.

    摘要： An X-ray computed tomography apparatus includes a cone beam X-ray tube, an X-ray detector, a rotating mechanism for supporting the X-ray tube and X-ray detector, a moving mechanism for moving the object in the slice direction, a control unit for controlling the rotating mechanism and moving mechanism to execute helical scan operation and move relative to the object, an input device for setting a substantially cylindrical reconstruction area, and an image reconstructing unit for reconstructing image data within the set reconstruction area based on the output of the detector. The apparatus also includes a movement distance determining unit for determining the movement distance of the X-ray tube and X-ray detector relative to the object on the basis of the radius of the set reconstruction area as well as its height.

    摘要： A suspension seat for an automotive vehicle has a seat frame which is vertically movably supported on a parallel link mechanism. A compression spring and a shock absorber of a suspension unit are coaxially assembled. A spring bracket is disposed on the compression spring and screwed with a rod of the shock absorber. A fixing nut is fixed to the rod on the spring bracket to adjust elastic force of the compression spring by changing the position of the spring bracket. A projection of the spring bracket projects from a slit of a suspension unit support bracket with scale division. A resilient bracket supports the parallel link mechanism and outwardly projects to function as a bumper for a seat frame. Therefore, the suspension seat suppresses shock or sound due to impact during an operation of the seat and realizes a simple adjustment of hardness of the suspension unit.
