Abstract

Métodos y aparatos para la fabricación de cristales piezoeléctricos de diferentes características de frecuencia en los que se efectúan las siguientes operaciones: Apilado de los cristales primitivos unos sobre los otros para formar la pila, unión de dichos cristales primitivos para formar un bloque rígido, pulido de las cuatro caras de la pila en un plano perpendicular a las bases de la misma, pulido de las otras dos caras con un ángulo predeterminado de menos de 90º con la base para adelgazar la dicha pila en dos lados a un tamaño fijado de antemano mayor en un extremo y a un tamaño también fijado de antemano más pequeño en el otro extremo de la pila, separación de todos los cristales primitivos de dicha pila, obteniéndose un cristal primitivo de la más baja frecuencia predeterminada en un extremo, un cristal primitivo de la más alta frecuencia establecida de antemano en el otro extremo de la pila, y una serie de cristales primitivos de frecuencias comprendidas entre la más alta y la más baja de las citadas frecuencias predeterminadas.
