摘要:
An induction furnace for heating a workpiece includes a chamber and an insulation cylinder positioned therein, with the insulation cylinder including a base cover movable between first and second positions, and the first position positioning the workpiece within a heating zone and the second position positioning the workpiece within a cooling zone. A translation system in the furnace includes a first member coupled to the base cover of the insulation cylinder and extending through a wall of the chamber, an actuator coupled to the first member, the actuator configured to translate the first member to move the base cover of the insulation cylinder between the first and second positions, and an expansion member encircling a portion of the first member and configured to hermetically seal an interior volume of the chamber from an environment volume external to the chamber.
摘要:
A bearing assembly is disclosed that includes a sleeve having an opening formed therein and a shaft positioned within the opening of the sleeve such that a gap is formed between an inner surface of the sleeve and an outer surface of the shaft. A lubricant is disposed in the gap and a plurality of grooves are formed on at least one of the outer surface of the shaft and the inner surface of the sleeve. An anti-wetting coating is disposed on the at least one of the outer surface of the shaft and the inner surface of the sleeve between adjacent grooves of the plurality of grooves.
摘要:
A structure and associated process for joining dissimilar materials to form various components of an x-ray tube is illustrated that utilizes one or more intermediate or interfacial filler material members positioned between the primary welding or mating surfaces of the base material components to be joined. The use of the interfacial or intermediate filler material preserves the multiple benefits of friction welding, as well as enabling the joining of highly dissimilar material components, decreasing the required joining temperature, and providing increased microstructural control of the resulting weld or joint.

An emitter for a cathode of an X-ray tube is provided that includes a shaped emitting surface. The emitting surface is shaped in a suitable process in order to enable the emitting surface to focus electron beams emitted from the emitting surface on a focal spot on a target of less than 1.0 mm without the need for any additional focusing elements in the X-ray tube.
