Patent number: 11414320Abstract: A method for producing a thin-film layer includes providing a layer stack on a carrier substrate, wherein the layer stack includes a carrier layer and a sacrificial layer, and wherein the sacrificial layer includes areas in which the carrier layer is exposed. The method includes providing the thin-film layer on the layer stack, such that the thin-film layer bears on the sacrificial layer and, in the areas of the sacrificial layer in which the carrier layer is exposed, against the carrier layer. The method includes at least partly removing the sacrificial layer from the thin-film layer in order to eliminate a contact between the thin-film layer and the sacrificial layer in some areas. The method also includes detaching the thin-film layer from the carrier layer.Type: GrantFiled: October 7, 2020Date of Patent: August 16, 2022Assignee: INFINEON TECHNOLOGIES AGInventors: Alfred Sigl, Wolfgang Friza, Stefan Geissler

Patent number: 6684475Abstract: A large dimension hollow body such as a fuel tank is formed from cold deformable sheet metal by cutting a sheet metal blank of a conformation matching the hollow structure to be formed and which has a nonuniform cross section between its ends. The sheet metal blank is then formed into a three-dimensional shape closed at one end and subjected to hydrostatic forming, whereupon the other end is closed optionally after insertion of an object to be received in the tank such as a fuel pump. The welding of the edges of the blank together and the application of the caps can produce pressure-tight weld seams and can be effected by laser-beam welding or tungsten inert gas welding.Type: GrantFiled: March 26, 2001Date of Patent: February 3, 2004Assignee: HDE Solutions GmbHInventors: Stefan Geissler, Karl Norbert Lohmann, Theodor Ostermann, Matthias Adolph

Publication number: 20020088611Abstract: A tube bundle heat exchanger has heat exchanger tubes which are formed over the length of the tube and especially the central region with uniform constricting formations. The degree of constriction, however, is reduced from the central region toward the outlet end, e.g. by reducing the depth of the formations, by increasing the pitch or pitch angle of helical formations, by increasing the spacing of the formations or by any combination thereof. The result is enhanced heat exchange efficiency and/or reduced pressure drop.Type: ApplicationFiled: January 2, 2002Publication date: July 11, 2002Applicant: hde METALLWERK GmbHInventors: Stefan Geissler, Berthold Droste, Engelbert Wortmann, Joachim Kautz, Dirk Sczech, Lars Hartbecke
