FIELD: electronic engineering end-type miniature cathodes for picture tubes and cathode-ray tubes. SUBSTANCE: cathode base is made of two similar halves each shaped by bending lugs made on initially flat plate. One plate carries group of half-bases. Emitter is connected to half-bases by sintering. EFFECT: simplified design and facilitated manufacture of cathodes and, hence, reduced cost enabling quantity production of cathodes for picture tubes using such cathodes. 3 cl, 4 dwg
