Abstract

TUBO DE RAYOS CATODICOS PARA VISUALIZACION EN COLOR. CONSTA DE UN TUBO DE RAYOS CATODICOS CON CAÑON ELECTRONICO DEL TIPO DE HACES EN LINEA COPLANARIOS Y CONVERGENTES EN LA PANTALLA (10) DE PRESENTACION. LOS HACES SUFREN DESVIACIONES EN DOS DIRECCIONES PERPENDICULARES ENTRE SI POR MEDIO DE DOS CAMPOS ELECTROMAGNETICOS DE DESVIACION. EL CAÑON ELECTRONICO INCORPORA UNOS PERFILADORES DE CAMPO (34, 35) PARA CONSEGUIR QUE LOS CUADROS DESCRITOS POR LOS HACES DE ELECTRONES EN LA PANTALLA COINCIDAN. LOS PERFILADORES COMPRENDEN UNOS ELEMENTOS ANULARES (34) DE UN MATERIAL DE GRAN PERMEABILIDAD MAGNETICA, EN TORNO A LOS DOS HACES EXTERIORES.
