High-yield cathode body, cathode sleeve structure, and cathode-ray tube, cathode sleeve substrate, and cathode body production method
摘要:
A cathode sleeve structure for housing a heater. The cathode sleeve structure includes: a case member that is cylindrical and an end thereof is open; a plurality of supporting members that extend radially from vicinities of the end of the case member; and a linkage member that connects the plurality of supporting members. The case member, the plurality of supporting members, and the linkage member are formed as one piece.
