Abstract

Structure composite perfectionnée assurant un chauffage autorégulé, au moyen d'un courant à haute fréquence qui lui est appliqué. La structure 13 comprend un trajet de courant constitué par une couche ferromagnétique 25 ayant un point de Curie proche de la limite supérieure désirée de l'intervalle de température de fonctionnement et par une autre couche 23, 21 qui est en contact électrique avec la couche ferromagnétique et qui a une perméabilité magnétique utile nettement inférieure et des conductivités thermiques et magnétiques nettement supérieures à celles de la couche ferromagnétique. Application aux bistouris électriques.Advanced composite structure providing self-regulated heating by means of a high frequency current applied to it. Structure 13 includes a current path consisting of a ferromagnetic layer 25 having a Curie point near the desired upper limit of the operating temperature range and another layer 23, 21 which is in electrical contact with the ferromagnetic layer. and which has significantly lower useful magnetic permeability and significantly higher thermal and magnetic conductivities than the ferromagnetic layer. Application to electric scalpels.
