Abstract

Perfeccionamientos en una disposición de circuito para la supresión de mancha de foco en un tubo de imagen al cesar las partes de barrido, en la que un condensador acumulador en servicio normal se carga positivamente respecto a masa, y su carga después del cese sirve para aplicar a un electrodo del tubo de imagen un potencial que bloquea la corriente del haz, caracterizado por un interruptor gobernado por un circuito de protección que reacciona al cese, el cual aplica bruscamente a potencial de masa la placa cargada positivamente del condensador acumulador.
