IPC: H01J7/18
Filed: 2003-04-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a getter, having a small and simple structure and easy to manufacture, and to provide a vacuum container suitable for the getter.  <P>SOLUTION: The evaporation type getter comprises tubing 2 using fibers made of a conductive metal wire (for example, a metal containing Ti as a main component), and a material having appropriate thermal resistance and electric insulation so that the material is not melted at the evaporation operation temperature of the metal. A structure with the metal wire inserted is provided in an inner space of the tubing. Electrical current is applied to the metal wire to allow the material to evaporate, and to attach at least to the tubing. Because the metal wire which can be high temperature is wrapped by the insulating tubing, the metal wire can be evaporated with maintaining the heat of the heated metal wire. Accordingly, the insulating structure can be simple, easy to manufacture, small, and low cost. Because the tubing uses fibers, the surface area is wider allowing a wider deposition area to be obtained for an improved discharge speed.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
