    摘要： In an X-ray tube, a rotary anode formed into a hollow disk-like shape is fixedly supported by a rotating body formed into a hollow cylindrical shape. A fixed shaft has fixed ends, columnar bearing portions and a disk part, and a flow path of a cooling medium formed along a central axis thereof. The bearing portions are inserted into the rotating body with a first gap between the columnar bearing portion and the rotating body, so that the rotating body is rotatably supported. The disk part is arranged in the rotary anode with a second gap between the disk part and the rotary anode. The first and second gaps are filled with a lubricant, bearing grooves are formed in the bearing portion, thereby forming dynamic pressure bearings, and a center of gravity of the rotary anode is arranged between the first and second dynamic pressure bearings.

    摘要： Fins are arranged on the rotating side of an X-ray computed tomography apparatus. The fins are rotated to generate airflow as the rotating side is rotated. This airflow serves to discharge wear debris to the outside of the X-ray CT apparatus, thereby preventing the wear debris from scattering toward an X-ray tube and support bearing. In consequence, in the X-ray CT apparatus provided with a slip ring, the wear debris produced in a contact space between the slip ring and a brush can be prevented from being scattered in the apparatus.

    摘要： In a rotary anode X-ray tube, a disc portion is fitted into a rotary anode with a first gap therebetween and a fixed shaft is fitted into a rotary shaft to support the anode with a second gap therebetween. The disc portion and the fixed shaft are formed integral with each other to have a hollow portion therein. A cooling liquid is allowed to flow through the hollow portion. A liquid metal is filled in the first and second gaps. Dynamic pressure type bearings is formed in the second gap. A passage is formed to directly communicate the first gap to the second gap, whereby the liquid metal being directly supplied from the second gap to the first gap. Thus, the liquid metal can be fed rapidly and surely into the gap between the anode target and a cooling vessel.

    摘要： A sheet post-processing device includes a conveying member configured to convey a sheet-like recording medium, a processing unit configured to perform a given operation upon the recording medium conveyed by the conveying member, a communication unit configured to communicate with a device external to the sheet post-processing device for the given operation performed by the processing unit, a control unit configured to control, via the communication unit, information passing between the sheet post-processing device and the external device at a desired timing, and a storing unit configured to store information of the recording medium transmitted from the external device. The control unit transmits the information at one of a timing before a discharge of the recording medium and a timing after a discharge of the recording medium.
