Patent number: 6197387Abstract: The invention relates to the production of thin metal layers and structures thereof on substrates of various structures. The lateral extent of a metal layer on the respective substrate can be prescribed with a precision in the micron and submicron range. The method described makes it possible to manufacture flat and three-dimensional metal structures on smooth planar or curved surfaces, as are required, for example, for depicting writing or drawings. The method uses no printing techniques.Type: GrantFiled: July 1, 1999Date of Patent: March 6, 2001Assignees: Fraunhofer-Gesellschaft Zur Foerderung Der Angewandten Forschung E.

Patent number: 6099711Abstract: The invention relates to a method for the electrolytic deposition of metal coatings, in particular of copper coatings with certain physical-mechanical and optical properties and uniform coating thickness. According to known methods using soluble anodes and applying direct current, only uneven metal distribution can be attained on complex shaped workpieces. By using a pulse current or pulse voltage method, the problem of the coatings being of varying thickness at various places on the workpiece surfaces can indeed be reduced. However, the further problem of the geometric ratios being changed continuously during the depositing process by dissolving of the anodes is not resolved thus. This can be avoided by using insoluble anodes.Type: GrantFiled: April 23, 1998Date of Patent: August 8, 2000Assignee: Atotech Deutschland GmbHInventors: Wolfgang Dahms, Heinrich Meyer, Stefan Kretschmer

Patent number: 4781362Abstract: Hydraulically damping elastic bearing with two rigid end walls opposite one another in the axial direction, and at least two chambers located one behind the other and containing damping fluid, at least one of which has a circumferential wall designed as an elastic spring element, whereby the chambers are separated from one another by a partition which is at least partly elastic exhibiting slits for an exchange of fluids. The elastic partition should thereby be designed so that when there is flow against the membrane from different chambers at the same pressure, a different pressure reduction is possible. For this purpose, the elastic partition is asymmetrical in cross section in relation to its center line, at least in the area of the slits, so that the opposite surfaces of the elastic partition are at different distances from the center plane in the area of a slit.Type: GrantFiled: July 17, 1987Date of Patent: November 1, 1988Assignee: BOGE GmbHInventors: Horst Reuter, Jorn-Rainer Quast, Heinz Brenner, Peter Maier, Heinrich Meyer
