  • Offset printing plates having high print run stability
    Patent number: 6238831
    Abstract: The invention relates to coating solutions, processes for the preparation of a printing plate using these coating solutions as well as printing plates prepared in this manner; in particular, the invention relates to printing plates the photosensitive layer of which contains homogeneously distributed polymer particles.

  • Method for working an electroformed magnetic metal sheet
    Patent number: 5926938
    Abstract: To planarize an electroformed, magnetic metal sheet having micropatterns, the metal sheet is clamped on a magnet and is mechanically processed on the back side of the metal in such a way that it assumes a plane-parallel shape. Metal sheets can be used which are not stress-free and are obtained in a fast electroplating process. Multiple copying is possible.

  • Integrated optical waveguide component and method of manufacture
    Patent number: 5867619
    Abstract: In a method for manufacturing an integrated, optical waveguide component having fiber couplings, a substrate component and a cover component are used, the cover component being obtained by forming a positive-negative replica of the substrate component. To separate the optical waveguide pattern region from the regions of the fiber couplings, grooves, as well as corresponding webs, are provided transversely to the fiber couplings. The method eliminates the need for carrying out the fiber adjustment and the waveguide formation in one process.
