Abstract

A DIRECTLY HEATED CATHODE STRUCTURE INCLUDES AT LEAST ONE POROUS PELLET (100) CONTAINING ELECTRON EMISSION MATERIAL AND FILAMENTS (200) SECURED TO AT LEAST THREE SIDE SURFACES OF THE POROUS PELLET (L00) TO SUPPORT THE PELLET STABLY AND PREVENT VIBRATION CAUSED BY SHOCK AND POTENTIAL DEFORMATION. EACH FILAMENT (200) IS SUPPORTED BY AN INSULATING BLOCK (300) AND MORE THAN ONE PELLET (L00) MAY BE MOUNTED ON A SINGLE INSULATING BLOCK (300). AS A RESULT, A HIGHLY RELIABLE CATHODE RAY TUBE CAN BE MANUFACTURED.@@(FIG. 12)
