摘要： A high-capacity x-ray tube particularly for use in medical technology in CT apparatuses, has a vacuum housing containing a cathode and a rotatably mounted anode. The anode plate of the anode is connected by a solder connection to the one end of a load-bearing part, the other end of which is attached to the bearing shaft of a drive for placing the anode in rotation. The mechanical strength of the connection location between the anode plate and the load-bearing part is improved by the connection being formed by a positive fit, designed such that the connection surfaces are subjected substantially only to compression given rotation of the anode.

摘要： A fall protection device for an opening in a roof includes at least one rail section having a vertical member. The vertical member is preferably in the form of a metal tube having an open lower end. A bearing foot has a connecting portion and a bearing portion and is secured to the lower end of the vertical member by the connecting portion so that the bearing portion supports the vertical member above the roof. The connecting portion of the bearing foot preferably extends into the open lower end of the tube and resiliently engages an interior surface of the tube to secure the bearing foot thereto. A hardness of the bearing portion is greater than a hardness of the connecting portion. The connecting portion and the bearing portion are preferably plastic and co-molded so that the bearing foot is of unitary construction.

摘要： An x-ray tube has a stationary cathode and a rotating anode in a vacuum housing. The anode is positioned on a housing-fixed axle such that it can be rotated, and is fashioned as a hollow body in the interior of which an axle-fixed ring projection is disposed, such that, at least between an inner surface of the rotating anode and the adjacent outer surface of the ring projection, a gap exists that is filled with liquid metal and forms a liquid-metal fluid bearing for the rotating anode.

摘要： An anode target (22) is rotatably supported by a rotating mechanism (25) having a rotary body (23) and a stationary body (28). A fitted portion between the rotary body (23) and the stationary body (28) is formed of bearing areas (L1) to (L4) having dynamic pressure type sliding bearings and a non-bearing area (L5) having a clearance between the rotary body (23) and the stationary body (28) larger than that in the bearing areas (L1) to (L4). The rotary body facing the non-bearing area is positioned where a time for heat transfer from the anode target (22) is shorter than the rotary body facing the bearing areas. Thus, the characteristics of heat radiation from the anode target (22) can be improved, and a stable bearing operation can be maintained.

摘要： To reduce the rotational power, an apparatus with a rotational body that is rotationally driven in a fluid-filled housing a rotational directing body is provided between the rotational body and the housing, which is rotatably supported coaxially with respect to the rotational body. The rotational directing body is configured such that in operation it rotates at an intermediate rotational frequency in comparison to the housing and the rotational body. The apparatus is particularly an X-ray radiator having a cathode and anode that are mounted in a vacuum tube in a spatially fixed manner in relation to the tube, the vacuum tube being rotationally driven as a rotational body in a coolant housing.

摘要： A rotating anode for an x-ray tube has an anode body composed of composite fiber material, mounted in a bearing system, the anode body having a target surface with a focal ring and including fibers with particularly high heat conductivity in the longitudinal direction. An axis-proximal cooling system is associated with the anode body. The majority of all fibers with high heat conductivity in the longitudinal direction terminate bluntly both at the focal ring and at the cooling system, such that their abutting faces respectively are in direct, heat-conducting contact both with the focal ring and with the cooling system.
