Title: Image receiving tube
Inventor: UOZUMI KENJI
IPC: H01J29/94
Filed: 1992-01-27
Abstract: PURPOSE:To prevent the deterioration of a resilient metal piece for use in an image receiving tube and facilitate the operation of inserting an electron gun by providing a long slot at the plate surface of the metal piece in the longitudinal direction, and decreasing the eddy current induced in the metal piece. CONSTITUTION:A band-shaped resilient metal piece 2, whose one end is fixed to the foremost tip of an electron gun 1, and a ring getter 3 secured to the other end constitute a getter structure. This structure curves alongside the funnel 5 of a glass envelope 4, and the getter 3 is positioned alongside the long edge of the inner surface of the funnel 5 where the dimensional margin is the greatest. If the getter material of the getter 3 is flushed by high frequency heating, the getter film of large area is formed over the inner surface of the funnel 5. As a result, a slot 8 partially blocks the path of eddy current generated when the line of magnetic force of a horizontal deflecting magnetic field acts on the metal piece 2, and the generation of Joule's heat can be suppressed to a great extent.
