Abstract

Un tubo (10) de rayos catodicos incluye una mascara de tension (30) acoplada con un montaje (10) de marco de mascara rectangular que tiene dos lados (22, 24) largos paralelos al eje X central mayor del mismo y dos lados cortos (26, 28) paralelos al eje Y central menor del mismo. Un par de miembros (40, 140) de paleta de soporte estan acoplados a cada uno de los lados largos (22, 24) o los lados (26, 28) cortos en una posicion central. Cada miembro (40, 140) de paleta de soporte incluye un borde interno que tiene una pluralidad de primeros lados (42, 44, 46) formados de un material de expansion termica con un coeficiente relativamente bajo y un borde exterior que tiene un segundo lado formado de un material que tiene un coeficiente relativamente alto de expansion termica. Cada borde tiene un punto central separado entre si a lo largo del eje Y menor.
