Abstract

DISPOSITIVO QUE ELIMINA LOS PEQUEÑOS ERRORES DE CONVERGENCIA ESTATICA HORIZONTAL, MANTENIENDO UN CAMPO MAGNETICO MULTIPOLAR ESTATICO PARA LA PRESENTACION DE IMAGENES EN COLOR. CONSTA DE UN IMAN DE CORRECION (20), FUERA DEL CUELLO DEL TUBO Y CERCA DE LA SALIDA DE CAÑONES ELECTRONICOS; DICHO IMAN FORMA UN DIPOLO MAGNETICO, SIENDO PEQUEÑO EN COMPARACION CON LA DISTANCIA A LOS HACES, LA INFLUENCIA EN UN PUNTO DE LOS HACES ES INVERSAMENTE PROPORCIONAL A LA TERCERA POTENCIA DE LA DISTANCIA DE LOS HACES; EL HAZ ELECTRONICO CENTRAL (9) ESTA CONSIDERABLEMENTE MENOS INFLUENCIADO POR EL CAMPO MAGNETICO QUE LOS HACES ELECTRONICOS ADYACENTES (8, 10); LA PUREZA DEL COLOR SE CORRIGE MAGNETIZADO EL ANILLO (18), DE MATERIAL MAGNETICO SEMIDURO, DISPUESTO ALREDEDOR DE LOS HACES ELECTRONICOS Y SIN QUE SEA NECESARIA SU REMAGNETIZACION POSTERIOR.
