摘要： An x-ray emitting window is formed at a front end face, and a taper surface tilted with respect to the x-ray emitting direction is formed near the emitting window, whereby an object to be inspected can be prevented from abutting against the front end face even if the object is pivoted about an axis intersecting the emitting direction while the object is disposed closer to the x-ray emitting window. As a consequence, while the object is disposed closer to the x-ray emitting position, the orientation of the object can be changed. Therefore, when inspecting the internal structure of the object and the like by irradiating the object with x-rays and detecting the x-rays transmitted through the object, not only a magnified penetration image of the object with a high magnification rate is obtained, but also the internal structure of the object and the like can be verified in detail by changing the orientation of the object.
摘要翻译： X射线发射窗形成在前端面，并且在发射窗附近形成相对于x射线发射方向倾斜的锥形表面，由此可以防止被检查物体抵靠前端即使物体绕着与发射方向相交的轴线枢转，同时物体靠近X射线发射窗口设置。结果，当物体设置得更靠近x射线发射位置时，可以改变物体的取向。因此，当通过用X射线照射物体并检测透过物体的x射线来检查物体等的内部结构时，不仅获得了具有高放大率的物体的放大穿透图像，而且也可以通过改变物体的取向来详细地验证物体等的内部结构。

摘要： The present invention relates to an X-ray tube, having a structure enabling capturing of a clear magnified transmission image and enabling increase of a magnification factor of the magnified transmission image, and an X-ray source including the X-ray tube. In the X-ray tube, X-rays are generated by making electrons from an electron gun incident onto an X-ray target of an anode, disposed inside an anode housing unit, and the generated X-rays are taken out from an X-ray emission window. In particular, the anode housing unit has a pair of conductive flat portions disposed parallel to a reference plane, orthogonal to an electron incidence surface of the X-ray target, and so as to sandwich the X-ray target. The reference plane contains a first reference line, joining an electron emission exit center of the electron gun and an electron incidence surface center of the X-ray target, and a second reference line, being a straight line intersecting the first reference line on the electron incidence surface of the X-ray target and joining the electron incidence surface center and an X-ray emission window center.

摘要： In an X-ray source 1 and an X-ray tube 4, there is formed a shield portion 42 adapted to shield the portion W where a target support body 18 and an opening portion 34 on the other end side of a valve 20 are fixed to each other when viewed from the one end side of the valve 20. Therefore, the generation of discharge between the one end side of the valve 20 and the fixation portion W can be suppressed. Also, the other end portion of the valve 20 is formed as a narrowed portion 37 and the opening portion 34 on the other end side of the valve 20 is fixed to the target support body 18, whereby the shapes of the valve 20 and the shield portion 42 can be made simpler than in conventional X-ray tubes in which an inner cylindrical portion is formed in a valve. Such a simple structure can improve the stability of an electric field in the valve 20 when generating X-rays and thereby achieve an effective suppression of the generation of discharge in the valve 20.

摘要： An X-ray generator of this invention has an X-ray monitor that monitors a state of an X-ray emitted from a target. Hence the state of the X-ray can be monitored in real time to maintain the X-ray in a constant state. The X-ray monitor is positioned off the path on which an X-ray transmitted from a first exit window travels. Hence, when the X-ray is emitted from the first exit window to an object to be inspected, the X-ray monitor does not obstruct the approaching of the object to the first exit window. This makes it possible to acquire X-ray images of high magnification.
