专利汇可以提供Electric discharge tube comprising a rod grid专利检索,专利查询,专利分析的服务。并且A metal-ceramic tetrode or triode which comprises a cylindrical rod grid which is manufactured by means of a spark erosion process. In order to improve the mechanical stability of the grid and also to shift the resonant frequency to higher frequencies, the grid comprises wide and narrow rods. Since the wide rods bend inwardly or outwardly during the spark erosion process, the slots, to avoid said drawback, adjoining the wide rods extend in at least one inwardly extending flange of the cylinder farther in the direction normal to the curved surface of the cylinder than the slots present between the thin rods.,下面是Electric discharge tube comprising a rod grid专利的具体信息内容。

1. In an electric discharge tube of the type having at least one electrode consisting of a hollow metal cylinder in which slots are provided by means of a spark erosion process, said slots extending in the axial direction and in at least one inwardly extending flange of the cylinder also in a direction normal to the curved surface of the cylinder as a result of which a grid is formed which is constructed from thin rods of approximately the same cross-section, the improvement comprising that in addition to the thin rods, the electrode comprises a few wider rods which are bounded on either side by two slots which extend farther in the direction normal to the curved surface of the cylinder than the slots present between the thin rods.
2. An electric discharge tube as claimed in claim 1 wherein said tube is a metalceramic tetrode.
3. An electric discharge tube as claimed in claim 1 wherein the electrode is a control grid.
4. An electric discharge tube as claimed in claim 1 wherein the hollow cylinder is a circular cylinder.
5. An electric discharge tube as claimed in claim 1 wherein said tube is a metal-ceramic triode.
