Abstract
L'INVENTION CONCERNE UN ELEMENT GENERATEUR D'EFFET CORONA POUVANT ETRE CONNECTE A UNE SOURCE DE HAUTE TENSION POUR UNE CHARGE ELECTROSTATIQUE UNIFORME DE LA SURFACE D'UN ORGANE PHOTOCONDUCTEUR, ET IL EST FORME D'UN BRIN D'UN FIL METALLIQUE. SELON L'INVENTION, PLUSIEURS PARTIES MINCES ET ESPACEES 21 SONT FORMEES SUR LA LONGUEUR DU FIL 19, LES PARTIES MINCES AYANT UNE EPAISSEUR INFERIEURE AU CORPS DU FIL 19 ET CHAQUE PARTIE MINCE SE TERMINANT PAR AU MOINS UN BORD 23 CONSTITUANT UNE SURFACE D'EMISSION CORONA POUVANT GENERER UN EFFET CORONA LE LONG DES BORDS, QUI EST SENSIBLEMENT UNIFORME SUR TOUTE LA LONGUEUR DE L'ELEMENT. L'INVENTION S'APPLIQUE NOTAMMENT A L'ELECTROPHOTOGRAPHIE.
