The cathode ray tube where it can provide the electron gun and the electron gun where it can provide the potential divider and the potential divider

摘要

(57) Abstract The resistance type potential divider of the electron gun (20) business which is used for the cathode ray tube (30) (1) the backing (2) the hole (3) is locked inside and the surface of the backing (5) resistant layer above possesses the contact point element (7) which contacts (6). Each contact point element (7) the hole (3) has the 1st air itself (8) which is located inside. The 1st substance (8) has the wall (82) which stands up from bottom (81) and the said bottom, the wall the backing (2) has the rim (83) which pressure welding is done in the surface (4). Each contact point element (7) on bottom (81) of the 1st substance (8) in the weld (10) is welded and the backing (2) the 2nd surface (5) and possesses the 2nd substance (9) which is the leaf spring which pressure welding is done with the both sides. As this resistance type potential divider has simple structure, can actualize easily, that contact point element (7) resistant layer (6) brings clear contact.
