Abstract

LA PRESENTE INVENTION CONCERNE UN COMPOSANT ELECTRIQUE UTILISANT DES SUSPENSIONS CONDUCTRICES. CE COMPOSANT EST CARACTERISE EN CE QU'IL COMPREND UNE SUSPENSION DE PARTICULES FERROMAGNETIQUES OU PARAMAGNETIQUES CONDUCTRICES DE L'ELECTRICITE DANS UN FLUIDE PORTEUR ISOLANT, DE SORTE QUE LA CONCENTRATION DES PARTICULES DANS LE PORTEUR DETERMINE LA CONDUCTIVITE RELATIVE DE LA SUSPENSION CONTENUE DANS LE COMPOSANT. APPLICATION A L'OBTENTION DE RESISTANCES REGLABLES.
