Abstract
STYLE A POINTE CALORIFIQUE QUI SE DEPLACE SUR UN SUPPORT SENSIBLE A LA CHALEUR POUR Y TRACER UN GRAPHIQUE D'ENREGISTREMENT. LA POINTE DU TRACEUR A LA FOIS DIELECTRIQUE ET CALORIFUGE DE CE STYLE EST REVETUE D'UNE PELLICULE ELECTRIQUEMENT RESISTANTE. SUR DEUX FACES OPPOSEES DE CE TRACEUR SONT APPLIQUEES DEUX BANDES CONDUCTRICES DE L'ELECTRICITE RELIEES D'UNE PART A UNE SOURCE DE COURANT ELECTRIQUE ET D'AUTRE PART A LADITE PELLICULE RESISTANTE QUI, TRAVERSEE PAR LE COURANT ELECTRIQUE, CHAUFFE LA POINTE DU TRACEUR. APPLICATION AUX TECHNIQUES D'ENREGISTREMENT DE DONNEES.
