Abstract
Procedimiento de mando de una célula para inscripción electrolítica de caracteres, cuya célula es de halogenuro metálico, en el cual se hace circular a través de la célula una corriente eléctrica de mando dirigida en un primer sentido durante periodos de borrado y en el sentido opuesto durante periodos de escritura y una corriente de mando nula durante periodos de mantenimiento del estado de borrado y de periodos de mantenimiento del estado escrito, caracterizado porque se superpone a dicha corriente de mando una corriente débil de fuga que atraviesa la célula en dicho primer sentido correspondiente al borrado, por lo menos durante los periodos de mantenimiento del estado de borrado.
