Abstract

LA INVENCION ESTA RELACIONADA CON UN CIRCUITO OSCILANTE DE RESONANCIA (6) PARA EL ELEMENTO ELECTRONICO. LA TAREA DE LA INVENCION SE BASA EN PROPONER UN CIRCUITO OSCILANTE DE RESONANCIA (6) QUE SE PUEDE DESACTIVAR DE FORMA FIABLE. LA TAREA SE RESUELVE, GRACIAS A QUE EL CIRCUITO OSCILANTE DE RESONANCIA (6) SE COMPONE DE DOS CIRCUITOS IMPRESOS EN FORMA DE ESPIRAL (2, 3) Y UNA CAPA DIELECTRICA (4), BOBINANDOSE AMBOS CIRCUITOS IMPRESOS EN FORMA DE ESPIRAL (2, 3) EN DIRECCIONES OPUESTAS Y ESTANDO DISPUESTOS A AMBOS LADOS DE LA CAPA DIELECTRICA (4), DE MANERA QUE SE SOLAPAN, AL MENOS, PARCIALMENTE, PREVIENDOSE, AL MENOS, UNA ZONA SELECCIONADA (8) EN LA QUE SE FORMA UN CAMINO CONDUCTIVO ENTRE AMBOS CIRCUITOS IMPRESOS EN FORMA DE ESPIRAL (2, 3), TAN PRONTO COMO SE SUMINISTRE UNA ENERGIA LO SUFICIENTEMENTE ELEVADA MEDIANTE UN CAMPO ALTERNATIVO EXTERNO.
