Abstract: An X-ray tube includes: a vacuum housing configured to include an internal space which is vacuum; a target unit configured to be disposed in the internal space, and include a target that generates an X-ray by using an electron beam incident therein, and a target support unit that supports the target, the X-ray generated by the target being transmitted through the target support unit; an X-ray emission window configured to be so provided as to face the target support unit, and seal an opening of the vacuum housing, the X-rays transmitted through the target support unit being transmitted through the X-ray emission window; an elastic member configured to press the target unit in such a direction as to approach the X-ray emission window; and a target shift unit configured to shift the target unit pressed by the elastic member in a direction crossing an incidence direction of the electron beam.

Abstract: [Object] The present invention provides an X-ray irradiation device capable of adjusting the energy of X-rays in a wide range, and an analysis device equipped with the X-ray irradiation device. [Solving Means] An X-ray irradiation device according to an embodiment of the present invention focuses X-rays emitted from an X-ray generation mechanism to a predetermined focal position by a focusing mechanism. The X-ray generation mechanism has a structure which generates a plurality of X-rays having different wavelengths. The focusing mechanism has a structure in which the plurality of X-rays are focused to the same focal position by focusing elements having diffraction characteristics suitable for the wavelengths of the respective X-rays generated by the X-ray generation mechanism.

Abstract: An encapsulated stator assembly for use in stator-driven devices is disclosed. The encapsulated stator assembly includes a stator (52) and a covering portion (54) that envelops the stator. The purpose of the covering portion is multi-fold: first, the covering portion serves as a means for mounting and securing the stator, such as within the outer housing (11) of an x ray tube. Second, the covering portion is thermally conductive to enable heat produced by the stator during operation to be dissipated to the outer housing of the x-ray tube thereof. Additionally, the covering portion can include an x-ray absorbent material to reduce x-ray emission from the x-ray tube. Though x-ray tubes represent one advantageous application, the encapsulated stator assembly of the present invention can be used in a variety of motor and stator-driven devices. The encapsulated stator assembly is especially well suited for use in dirty or dusty environments.

Abstract: An X-ray tube anode target assembly having a support shaft connected to a pivot assembly and a movable anode target surface disposed at one end of the support shaft. A first drive assembly is operably arranged with respect to the support shaft to provide oscillatory motion to the anode target about a first axis substantially parallel to the support shaft and drive cylinder operably arranged with respect to the contact element to provide a pivoting motion to the support shaft. A second drive assembly is operably arranged with respect to the drive cylinder to provide an oscillatory motion to the drive cylinder, the second drive cylinder having a cam portion to provide linear motion to the support shaft parallel to the first axis. The target surface is maintained at a substantially constant angle of impingement and maintains a substantially fixed distance from a cathode during target motion.
