  • Zirconia ceramic cavities are made as follows. First, a zirconia powder as a raw material is poured into a mold in which a thin metal wire is tensioned to form a cylindrical body. Next, the formed cylindrical body is sintered at a high temperature of about 1200 ° C. Then, a diamond paste is flowed into the through-hole of the fired cylindrical body, and the inside is polished to finish the hole so as to have a predetermined size.

Abstract

L'invention concerne un connecteur destiné à une fibre optique, un procédé et un appareil de production associés et un produit renfermant ledit connecteur. Celui-ci (8) est obtenu au moyen d'électroformage consistant à disposer de fins fils isolants (6), de manière contiguë, sur une partie conductrice (7), par recouvrement de celle-ci (7) et des fins fils isolants (6) d'un métal déposé par électroformage et puis par ménagement d'un trou d'insertion (80) consistant à éliminer lesdits fils (6). Un tel connecteur ne nécessite ni un appareil de formage onéreux, ni une matrice. Etant donné qu'un procédé de mise à feu n'est pas nécessaire, une quantité importante d'énergie n'est pas nécessaire non plus et le travail et le temps nécessaires à la production peuvent être réduits. Un connecteur destiné à une fibre optique, conçu pour une production en série et présentant une productivité élevée peut ainsi être obtenu.
