Abstract: In X-ray tubes anodes are used which, are maintained in rotation during the production of X-rays for fluoroscopy and which anodes are supported by friction-diminishing members. The anodes are maintained in rotation for all operational periods during which there may be a wish to take X-ray radiographs. The anode is supported magnetically without contact, except an electrical one for transmitting current to the anode.

Abstract: A rotary anode arrangement for X-ray tubes wherein the anode plate and the driving rotor are connected with each other and are also connected with the connection of both outer rings of two bearings spaced from each other. Their inner rings lie upon a shaft constituting the rotary axis and located in a tubular piston. The invention is particularly characterized in that the driving rotor as well as the connection to the anode plate extend along the spacing between the two bearings and are fixed to the connection of the two bearings close to the edge of the bearing distant from the plate. At least a part of the connection between the plate and the attachment to the bearings consists of a tube with thin walls which constitutes a resilient element for selected sizes.

Abstract: There is provided an X-ray tube device having a configuration for preventing peeled-off solid lubrication films from scattering in an X-ray tube even when the solid lubrication film peels off a rotary bearing. The X-ray tube device includes: an anode (212) that is irradiated with an electron beam, thereby emitting X-rays; a rotary bearing (304) that rotatably supports the anode (212); a solid lubrication film which is formed on a front surface of the rotary bearing (304) and into which a ferromagnet is mixed from the rotary bearing (304); and an attractor (303) which attracts, with a magnetic force, the solid lubrication film that peels off the rotary bearing (304).

Abstract: In one example, an x-ray tube comprises an evacuated enclosure and a cathode disposed within the evacuated enclosure. An anode is also disposed within the evacuated enclosure opposite the cathode so as to receive electrons emitted by the cathode. A rotor sleeve is coupled to the anode, the rotor sleeve being responsive to applied electromagnetic fields such that a rotational motion is imparted to the anode. A magnetic assist bearing assembly rotatably supports the anode.

Abstract: In X-ray tubes with a rotating anode, the shielding of the stator is obtained by a first conductive layer that is deposited on the external wall of an insulating bell-shaped part and has an electrical discontinuity, and by a second conductive layer that is deposited on the internal wall of an insulating cup-shaped or bowl-shaped part, the bell and the bowl encasing the stator and thus creating an electrostatic screen against the high frequency oscillations that result from the "crackling" of the tube. The device can be applied to X-ray tubes for radiology instruments.

Abstract: A rotating anode X-ray tube is provided which includes an anode disk having a central axis of rotation and a circumferential peripheral edge lying in a plane perpendicular to that axis of rotation. A ring-shaped target is mounted to the disk adjacent the peripheral edge and the disk includes a mechanism formed integrally solid with the disk and remote from the target for mounting the disk to a support shaft of a rotor within a vacuum housing to permit rotation of the disk about the axis of rotation of the disk. The disk is formed integrally solid along the aforementioned plane, including that portion of the disk coincident with the axis of rotation and the disk has a thickness which increases progressively in a radially inward direction from the peripheral edge, including that portion of the disk between the target and the mechanism for coupling, to counteract a radially inward increase in the disk upon high speed rotation of the disk. A cathode is provided for bombarding the target with thermions to generate X-rays which escape the vacuum housing through an appropriately placed X-ray penetrable window.
