Abstract
EL DISPOSITIVO SEGUN EL INVENTO COMPRENDE DOS ELEMENTOS (9,10) OSCILANTES PUESTOS UNO CON RELACION AL OTRO POR INTERMEDIO DE AL MENOS UNA LAMINA ELASTICA (19) SOBRE LA CUAL ESTA FIJADA UNA CERAMICA PIEZOELECTRICA (24). AL NIVEL DE SU UNION CON EL ELEMENTO (9), UNA DE LAS DOS CARAS (20) DE LA LAMINA (19) ESTA PROLONGADA CON RELACION A LA OTRA CARA, GRACIAS A UN PROLONGAMIENTO FORMADO SOBRE DICHO ELEMENTO (9). LA CERAMICA (24) ESTA ENTONCES FIJADA SOBRE LA LAMINA (19), DE MANERA QUE FORME APOYO SOBRE DICHO PROLONGAMIENTO. EL INVENTO PERMITE EN ESPECIAL AUMENTAR LA EFICACIA DE LAS CERAMICAS UTILIZADAS PARA LA ACTIVACION DE LOS GIROMETROS LASER Y REDUCIR SU NUMERO.
