摘要： For the purpose of providing a parallel-link table that is moved up/down without moving the position of a subject in the longitudinal direction, an upper structure is placed over a base plate connected with a platform via parallel links, and a first bracket on the upper structure and a middle point of one parallel link are connected by a first position correcting link of a length half that of the parallel link using pivotal joint portions; and therefore, when the base plate is moved up/down with respect to the platform, the upper structure moves only in the vertical direction without moving in the horizontal direction, and the top plate over the upper structure, hence, the subject placed on the top plate can be moved up/down in the vertical direction without moving in the longitudinal direction.

摘要： In order to provide an aperture position adjusting mechanism in an X-ray CT system with low cost and high accuracy to enable stable reconstruction of X-ray tomographic images, a first shaft (23) is provided with a bore (23a) at a position offset from a center axis, and is rotatably supported by a base plate (20) orthogonally to a pair of rails (21a, 21b). A second shaft (25) is received and is rotatably supported within the bore (23a) through the first shaft (23). The aperture (6) is moved along the rails (21a, 21b) as the second shaft (25) is eccentrically rotated by a motor (7) and, following the eccentric rotation and in a direction opposite to that of the rotation, the first shaft (23) is eccentrically rotated around the center axis of the bore (23a).

摘要： An elevating device based on fluid control includes a pump and a cylinder that are connected to each other by a flow path, wherein the cylinder and a reservoir are connected to each other by a flow path via a fixed flow valve that allows fluid to flow at a predetermined flow rate. When a lowering operation of a table section is carried out, a pump-valve control unit brings a flow rate of discharge of the fluid by the pump and a flow rate of the fluid returned to the reservoir through the fixed flow valve into equilibrium and thereafter sets the flow rate of discharge of the fluid by the pump smaller than the predetermined flow rate thereby to reduce the amount of the fluid held in the cylinder.
