Abstract: In a light-emitting sealed body, a metal structure (electron emission structure) containing an easily electron-emitting material is used, so that it is not necessary to perform feeding for discharge between electrodes. Therefore, a feeding member does not need to be connected to the metal structure from the outside of a bulb. In addition, in the light-emitting sealed body, the metal structure is disposed in an internal space S of the bulb and a positioning unit of the metal structure is disposed only in the bulb. Therefore, in the light-emitting sealed body, the metal structure and the positioning unit do not penetrate the bulb and are not buried in the bulb and weakened portions are not formed in the bulb made of glass. Therefore, a sealing state of the bulb can be maintained surely.

Abstract: A cathode assembly is for use in a radiation generator and includes an ohmically heated cathode, and a support having formed therein a hole and a recess at least partially surrounding the hole. In addition, there is a mount coupled to the support. The mount includes a larger outer frame positioned within the recess, a smaller inner frame carrying the ohmically heated cathode and spaced apart from the larger outer frame, and a plurality of members coupling the smaller inner frame to the larger outer frame.

Abstract: A cathode eyelet has its cathode receiving end formed in an elliptical cross-section. Pressure on the long axis opens the short axis to a dimension large enough to admit the cathode. Removal of the pressure allows the sides of the ellipse defined by the short axis to collapse and frictionally retain the cathode in position until it is welded to the eyelet.
Abstract translation: 阴极孔眼的阴极接收端形成为椭圆形截面。 长轴上的压力将短轴打开到足以允许阴极的尺寸。 去除压力允许由短轴限定的椭圆的侧面塌陷并摩擦地将阴极保持在适当位置，直到其被焊接到孔眼。
