Abstract: In an X-ray tomographic apparatus, while rotating a gantry rotary section around a region where an object to be photographed is placed, the anode target of an X-ray tube is rotated at a predetermined high rotation rate and X-rays are emitted from the anode target. In emitting the X-rays, the rotation torque is increased to be larger than that prior to rotation of the gantry rotary section in accordance with the rotation drive power supplied to a stator coil. A decrease in rotation rate of the anode target of the X-ray tube can be prevented even during rotation of the gantry rotary section, radiation at a necessary and sufficient X-ray dose can be assured, and an X-ray tomographic image can be properly obtained.

Abstract: A rotary anode type X-ray tube comprises a thin gas passageway extending from a lubricant chamber formed along the axis of a stationary structure and open at a fine gap G effective for preventing a lubricant leakage. In manufacturing the tube, a liquid metal lubricant is supplied to the lubricant chamber and to a slide bearing section, followed by assembling the tube and, then, sealing the assembled tube in a vacuum vessel. In the subsequent exhausting step, an open end of the gas passageway is allowed to face upward. The particular exhausting operation permits completely releasing to the outside the gas impregnated in the bearing-constituting members and the liquid metal lubricant, making it possible to maintain a stable bearing function.

Abstract: A rotary-anode X-ray tube having a rotor, a stationary shaft, and a sliding bearing connecting the rotor and the stationary shaft, forming a gap filled with liquid metal lubricant. The rotor has a first rotary member supporting an anode target and a second rotary member at which a sliding bearing is installed and which is coaxial with the first rotary member. The first and the second rotary members are connected at that end of the heat conductive path which is remote from the anode target. A heat insulating gap is formed at all fitting portions, but the remote end. Therefore, the temperature rise of the sliding bearing is controlled without using refregerant, and stable rotation of the bearing is secured.
