Abstract

PURPOSE:To simplify the assembling work of electron tubes abd further uniform the heat radiating characteristics of the electron tubes, by integrally forming the positive electrode and heat radiating body of each electron tube with a same material. CONSTITUTION:Fines 22 are formed from a cylindrical positive electrode 21 for a magnetron by a machining method, so-called, rolling method wherein the fines 22 are integrally extended from the electrode 21. The fines 22 may be formed into a spiral projection or, alternatively, may take a form of plural flangelike pieces. The fines 22 are easily formed by said rolling method wherein a cylindrical body having a wall thicker than the thickness of the intended electrode 21 is selected as a starting material, it is locally pressed while rotating the same and consequently unpressed parts are projected.
