Patent number: 11525392Abstract: A longitudinally adjustable connecting rod with a hydraulic control device for effecting a change in the effective length of the connecting rod is provided. The hydraulic control device comprises a hydraulic control valve which comprises a hydraulically actuatable control slide that is preloaded by way of a control slide spring, and two outlet valves which can be actuated by the control slide by way of two control contours arranged at a distance from one another. The control slide comprises a low-pressure section with a low-pressure piston for hydraulically actuating the control slide. For optimizing the control slide for such a longitudinally adjustable connecting rod, the two control contours are arranged together in a high-pressure section of the control slide which is arranged on one side of the low-pressure section and separated therefrom by way of a sealing section disposed therebetween.Type: GrantFiled: October 8, 2019Date of Patent: December 13, 2022Assignees: IWIS MOTORSYSTEME GMBH & CO. KG, AVL LIST GMBHInventors: Malte Heller, Stefanie Bezner, Christian Gallob, Martin Rath, Bernhard Kometter

Patent number: 10254655Abstract: An optical membrane element for an optical device in lithography, especially EUV (extreme ultraviolet) lithography, includes at least one membrane layer and a frame, which at least partially surrounds the membrane layer and at which at least part of the rim of the membrane layer is mounted. At least one tautening element is provided, which facilitates tautening of the membrane layer and wherein the optical membrane element can be used in a projection exposure system, especially for EUV lithography, such that the membrane layer of the membrane element can be adjustably tautened, such that the membrane layer is flat. A method for manufacturing a corresponding optical membrane element includes generating a tautening element lithographically together with the membrane layer.Type: GrantFiled: June 2, 2015Date of Patent: April 9, 2019Assignee: Carl Zeiss SMT GmbHInventors: Ulrich Mueller, Martin Rath
