摘要： An improved x-ray system/tube comprising an enclosure having oil contained therein, an oil pump, for circulating oil within the system, at least one cooling structure operatively connected to the enclosure and the oil pump, for cooling the oil, an x-ray tube, operatively positioned inside the enclosure for generating and directing x-rays toward a target, the x-ray tube comprising: a glass envelope, a cathode, operatively positioned in the glass envelope, an anode assembly including a rotor and a stator, operatively positioned relative to the rotor, a target, operatively positioned relative to the cathode and operatively connected to the anode assembly, for directing x-rays out of the system, and bearing structure having opposing surfaces and lubricant means having debris therein, operatively connected to the anode assembly, for enabling the target to rotate at a high rate and at a low resistance, the bearing structure including means for capturing the debris such that bearing performance is maintained at or near the level of a bearing structure having no debris therein. The debris capturing means can be grooved, operatively positioned in the bearing structure, for preventing debris from moving to the interface point between the bearing surfaces. This can be accomplished by positioning various grooves in various types of bearing and by forming ridges in the grooves already in the bearing for capturing the debris.

摘要： An improved high performance x-ray tube having a rotating graphite anode therein and method of preparation thereof. The surface of a graphite anode body is oxidized in air for removing the surface damage caused during the machining of the anode body. The anode body is provided with a diffusion barrier layer of rhenium contiguously disposed on the substantially damage free surface of the anode body. An anode target layer is then deposited on top of the barrier layer.

摘要： A cavity of predetermined size is formed in a compressed pressure transmitting powder medium, a mass of diamond crystals in contact with a mass of elemental silicon are disposed within the cavity and additional pressure transmitting powder is placed over the cavity and its contents producing a powder-enveloped cavity. Pressure is applied to the powder medium resulting in substantially isostatic pressure being applied to the cavity therein and its contents sufficient to dimensionally stabilize the cavity and its contents. The resulting shaped substantially isostatic system of powder-enveloped diamond and silicon is hot-pressed to liquefy and infiltrate the silicon through the interstices between the diamond crystals producing, upon cooling, an adherently bonded integral body.
