Abstract
UN CONJUNTO DE TRANSDUCTOR/TRANSFORMADOR DE PELICULA DELGADA INCLUYE UN CONJUNTO TRANSDUCTOR MAGNETICO DE PELICULA DELGADA 10 FORMADO EN UNA PRIMERA UBICACION EN UNA SUPERFICIE DE SOPORTE DE UN SUBSTRATO 12 Y UN CONJUNTO TRANSFORMADOR DE PELICULA DELGADA 40 FORMADO EN UNA SEGUNDA UBICACION DE LA SUPERFICIE DE SOPORTE DEL SUBSTRATO 12. EL CONJUNTO TRANSDUCTOR 10 Y EL CONJUNTO TRANSFORMADOR 40 ESTAN PROVISTOS CON BOBINAS CONDUCTORAS ELECTRICAMENTE QUE ESTAN MUTUAMENTE ACOPLADOS POR CIRCUITOS CONDUCTORES ELECTRICAMENTE 30-33 QUE SE EXTIENDEN ENTRE LOS MISMOS. EL CONJUNTO TRANSDUCTOR INCLUYE UN ELEMENTO POLAR INFERIOR, UN ELEMENTO POLAR SUPERIOR Y UN UNA BOBINA CONDUCTORA ELECTRICAMENTE SITUADA ENTRE LOS ELEMENTOS POLARES SUPERIOR E INFERIOR. LOS ELEMENTOS POLARES ESTAN MUTUAMENTE ACOPLADOS A LAS REGIONES DE SEPARACION POSTERIORES DEL MISMO Y TIENEN EXTREMOS POLARES QUE ESTAN MUTUAMENTE SEPARADOS Y AISLADOS. EL CONJUNTO DEL TRANSDUCTOR INCLUYE UN ELEMENTO POLAR INFERIOR, UN ELEMENTO POLAR SUPERIOR QUE FORMA UN CIRCUITO MAGNETICO CERRADO CON EL ELEMENTO POLAR INFERIOR, LOS ELEMENTOS POLARES SUPERIOR E INFERIOR FABRICADOS DE UN MATERIAL MAGNETICAMENTE PERMEABLES, Y UNA BOBINA CONDUCTORA ELECTRICAMENTE SITUADA ENTRE LOS ELEMENTOS POLARES SUPERIOR E INFERIOR. LA BOBINA TIENE UN PAR DE EXTREMOS Y UNA CONEXION EN DERIVACION SITUADA ENTRE LOS EXTREMOS. LOS ELEMENTOS POLARES ESTAN MUTUAMENTE ACOPLADOS EN LOS EXTREMOS OPUESTOS Y CENTRALMENTE A LOS MISMOS POR MEDIO DE UNA PARTE CENTRAL DE DEPENDENCIA HACIA ABAJO QUE SE EXTIENDE DESDE EL ELEMENTO POLAR SUPERIOR A LA PARTE INTERMEDIA DEL ELEMENTO POLAR INFERIOR. LA BOBINA DEL TRANSDUCTOR Y LA BOBINA DEL TRANSFORMADOR ESTAN ELECTRICAMENTE ACOPLADAS DE TAL FORMA QUE LA SEÑAL DE SALIDA SUMINISTRADA POR LA BOBINA DEL TRANSFORMADOR ES UNA SEÑAL IMPULSADA ELECTRICAMENTE DE AMPLITUD SUPERIOR A LA SEÑAL GENERADA POR LA BOBINA DEL TRANSDUCTOR.
