摘要： A rotatable anode target for an X-ray tube (1) of the present invention includes a metallic disc (2) which includes a first crystal structure; a metallic cylinder (3) which is joined with the metallic disc and includes a second crystal structure, where a first average aspect ratio of first crystal grains positioning at a first region within 2 mm from a interface between the metallic disc and the metallic cylinder is less than 2, and a second average aspect ratio of second crystal grains positioning at a second region within 2 mm from the interface is 2 or more and 8 or less. It is thereby possible to provide an X-ray tube target which has high heat release performance and where thermal deformation is difficult to occur.

摘要： A rotary current-collecting device includes a rotary slip ring and brushes coming into sliding contact with the outer peripheral surface of the slip ring. The brush-holding ring has an inner surface to which three brush-holding springs are fixed by screws. Each of the brushes is fixed to the tip end of the brush-holding spring and is pushed against the outer surface of the slip ring under the resilient restoration force of the brush-holding spring. When the slip ring revolves, the brushes come into sliding contact with the outer peripheral surface of the slip ring. The brush is made of a metal-graphite compound consisting of 70 weight percent copper and 30 weight percent graphite. The slip ring is entirely made of glassy carbon, so that the brush abrasion can be reduced.

摘要： An X-ray tube includes a rotor body having an outer sleeve of copper and an inner sleeve of steel, the two sleeves being joined by brazing. A black coating is applied to the outer surface of the copper sleeve and the inner surface of the steel sleeve, as well as to the outer surface of a copper bearing housing concentrically disposed within the rotor body. A steel spindle is concentrically and rotatably supported within the housing by a bearing structure and is rigidly affixed to the rotor body to support the rotor body for rotation. The X-ray tube also includes an anode comprised of molybdenum having a coating of rhenium-tungsten. The anode is supported on a shaft comprised of a material having a low coefficient of thermal conductivity such as niobium, an alloy of niobium, molybdenum, or an alloy of molybdenum. The X-ray tube further includes a bearing structure having portions lubricated by lead. The bearing structure includes a grooved outer race which is coated with ion-implanted lead, an inner race comprising a grooved portion of the spindle, and a plurality of lead-burnished balls disposed between the races.
