極構体。 The legs on both sides of the central part of the filament, which will become the electron-emitting part, are bent at right angles in one direction, extended parallel to each other, then folded back into a U-shape, and then laterally bent to form fixed parts at both ends. Each filament has a structure in which it is joined in surface contact with the flat top surface of a rod-shaped filament support, and the filament is made of a single thin plate and the center lines of all parts are located on the same plane and are bent and formed 2. A directly heated cathode assembly characterized in that the center portion, which is the electron emitting portion, is projected by a predetermined distance in the electron beam emission direction from the position of the both end fixing portions.
