DISPOSITIF DE SUSPENSION DU MASQUE D'OMBRE D'UN TUBE DE VISUALISATION CATHODIQUE COMPRENANT UN BILAME ET BILAME

摘要

A suspension device (8) for a CRT shadow mask (1) consists of a thermostatic bimetallic strip (10) exhibiting a deflection at 60-130 degrees C which is less than (preferably less than 0.8, especially less than 0.65 times) that at 20-60 degrees C. Also claimed is a bimetallic strip exhibiting a deflection at 60-130 degrees C which is less than that at 20-60 degrees C and which preferably consists of an austenitic stainless steel and an Fe-Ni alloy containing 27-32 wt.% Ni.
