Alignment means for electron gun structures

摘要

Improved means is provided for aligning an electron gun assembly of a cathode ray tube within the encompassing neck portion of the envelope. The alignment improvement is a one-piece crown-like structure comprising a band-like base member having a plurality of spaced-apart snubber projections extending in a substantially normal manner therefrom. The opposing ends of the base member are joined by adjustable jointure means to facilitate contiguous placement and bonding of the alignment means upon the terminal electrode of the gun assembly.
