REINFORCEMENT BAND FOR COLOR CATHODE RAY TUBE

摘要

PURPOSE: A reinforcement band is provided to prevent a mis-landing of electron beam by minimizing the vertical movement of electron beam. CONSTITUTION: A reinforcement band(120) has a longer side(121) and a shorter side(123) made of different materials. The longer side is made of a material having a low magnetic permeability, and the shorter side is made of a material having a high magnetic permeability. The material of the longer side has the maximum magnetic permeability of 2000(G/0e) or lower, and the material of the shorter side has the maximum magnetic permeability of 2000(G/0e) or higher.
