摘要： A field emission device (100) uses single crystals in order to eliminate grain boundaries within some or all of the electrodes (103, 104, and 205). The elimination of grain boundaries reduces susceptibility to damage, improves stability of the device (100), and improves uniformity and reproducibility among devices. In a preferred embodiment, the emitter and gate electrodes (103 and 104 respectively) are formed from a single crystal thin film (302). In other embodiments, other structures are employed wherein one or more of the electrodes (103, 104, and 205) are formed from single crystals.

摘要： An integrated bearing assembly is provided, comprising a bearing housing defining an axial cavity in which a shaft is disposed. The shaft is rotatably supported by at least two bearing sets. The axial cavity defines three regions, each having distinct diameters. A pair of first regions defines cavity diameters sufficient to receive the bearing sets. A pair of second regions defines cavity diameters such that a small gap is defined between the inner surface of the cavity and the shaft. The third region cooperates with the shaft to define a cylindrical volume containing a coolant. Wettable coatings are utilized in the cylindrical volume to allow free flow of, and maximum contact with, the coolant. Non-wettable coatings are provided in the second regions to contain the coolant. The second regions also function as bearing spacers, thus simplifying bearing assembly design, assembly, and performance.
摘要翻译：提供了一种集成的轴承组件，其包括轴承壳体，所述轴承壳体限定轴设置轴向腔体。轴由至少两个轴承组可旋转地支撑。轴向腔体限定三个区域，每个区域具有不同的直径。一对第一区域限定足以容纳轴承组件的腔直径。一对第二区域限定空腔直径，使得在空腔的内表面和轴之间限定小的间隙。第三区域与轴配合以限定包含冷却剂的圆柱形容积。可润滑的涂层用于圆柱体积，以允许冷却剂的自由流动和最大程度的接触。在第二区域中提供不可润湿的涂层以容纳冷却剂。第二个区域也起到轴承间隔，从而简化了轴承组装的设计，组装和性能。

摘要： A filament assembly for use in an x-ray emitting device or other filament-containing device is disclosed. In one embodiment, an x-ray tube is disclosed, including a vacuum enclosure that houses both an anode having a target surface, and a cathode positioned with respect to the anode. The cathode includes a filament assembly for emitting a beam of electrons during tube operation. The filament assembly comprises a heat sink and a plurality of filament segments. The filament segments are configured for simultaneous emission of an electron beam for impingement on the target surface of the anode, and are electrically connected in series. Each filament segment includes first and second end portions that are thermally connected to the heat sink, and a central portion that can be configured with a modified work function for preferential electron emission.
