Publication number: 20250116339Abstract: A valve includes a body, an inlet configured to receive a pressurized gas, an outlet configured to receive the pressurized gas from the inlet, and a region configured to receive the pressurized gas from the inlet. The valve further includes a plug having a longitudinal axis and configured to be controllably moved within the body along the longitudinal axis. The plug is movable between a sealed position and at least one non-sealed position. The plug in the sealed position forms a first seal and a second seal with the body, the first seal between the inlet and the outlet and the second seal between the inlet and the region. The plug in the sealed position is biased towards the sealed position by the pressurized gas. The plug in the at least one non-sealed position is biased away from the sealed position by the pressurized gas.Type: ApplicationFiled: February 14, 2023Publication date: April 10, 2025Inventors: Cody John Pavel Esau, Joerg Zimmermann, James Hastings Wilkie, Nick Sirmas

Publication number: 20250044703Abstract: To measure an illumination angle distribution, which is established via a multiplicity of illumination channels of an illumination optics unit, on an object field via an obscured projection optics unit, a setpoint pupil lighting of an illumination pupil of the illumination optics unit is initially established. With the aid of the setpoint pupil lighting, whether splitting of a measurement pupil lighting into a reflection measurement pupil and a diffraction measurement pupil is desired is checked. Depending on the result of the check, a reflection measurement pupil lighting and/or a diffraction measurement pupil lighting of the illumination optics unit is established by establishing corresponding illumination channels. The reflection measurement pupil lighting is measured by inserting a reflective object into the object field and/or the diffraction measurement pupil lighting is measured by inserting a diffractive object into the object field. An actual pupil lighting is reconstructed from the measurement data.Type: ApplicationFiled: October 22, 2024Publication date: February 6, 2025Inventors: Robert BUSCHLINGER, Michael RAMOLLA, Joerg ZIMMERMANN

Publication number: 20240062919Abstract: A plasma compression system comprises a plasma containment vessel, an annular rotating core inside the vessel, and a plurality of compression drivers fixedly mounted to an outer surface of the vessel wall. The annular rotating core contains a liquid medium and is rotatable to circulate the liquid medium and form a liquid liner with a cavity. The rotating core comprises an outer surface spaced from an inner surface of the vessel wall to define an annular gap, and a plurality of implosion drivers each comprising a pusher bore with a pusher piston slideable therein. Each pusher bore extends through the rotating core. The plurality of compression drivers compresses a compression fluid in the annular gap and creates a pressure pulse, such that when the rotating core rotates and the liquid medium fills the pusher bores, the pusher pistons are operable to push the liquid medium inwards to collapse the liquid liner and compress a plasma in the cavity.Type: ApplicationFiled: December 16, 2021Publication date: February 22, 2024Inventors: Joerg ZIMMERMANN, Robert BOUCHAL, William Randolph SMITH, II

Patent number: 11711884Abstract: A plasma compression driver is connected to a plasma containment vessel containing a liquid medium that forms a liquid liner containing plasma, and comprises a pair of coaxially aligned pistons that are sequentially driven towards the liquid liner. A pusher bore containing a pusher piston is coaxial with and has a smaller diameter than a driver bore containing a driver piston such that an interconnecting annular face surface is defined at the junction of the driver and pusher bores. During the compression operation, a prime mover accelerates the driver piston towards the pusher piston and compresses a compression fluid, which accelerates the pusher piston and pushes the liquid medium in the pusher bore into the vessel, causing the liquid liner to collapse, and compressing the plasma. Outward forces on the vessel wall caused by compression driver recoil and increased vessel pressure is counteracted by an inward force applied by the compression fluid on the annular face surface during the compression operation.Type: GrantFiled: December 2, 2020Date of Patent: July 25, 2023Assignee: General Fusion Inc.Inventors: James Hastings Wilkie, Joerg Zimmermann, Martin Clifford Wight, Cody John Pavel Esau, Ivan Victorovich Khalzov

Patent number: 11242089Abstract: A chassis for a passenger car includes two main longitudinal chassis beams which are connected to one another via a bumper cross member. A support arrangement extends between the two beams and is supported on a central tunnel. The support arrangement forms a load path in an event of a collision-related force being applied to the passenger car where above and/or below the support arrangement an installation space region is provided for accommodating a component or unit in need of protection. The support arrangement includes a strut which extends in a region of a center of the passenger car between the two beams and which forms a protective device which transmits impact forces forwards to the central tunnel. The strut has a first longitudinal section that is deformable in a targeted energy-absorbing manner and a second longitudinal section which functions as a rigid beam.Type: GrantFiled: August 24, 2017Date of Patent: February 8, 2022Assignee: Daimler AGInventors: Michael Wirsing, Matthias Hildebrand, Andreas Freund, Peter Gere, Levent Aktay, Jan-Mark Opelka, Peter Kuemmerlen, Dietmar Kallfass, Jens Spremberg, Joerg Zimmermann, Dieter Edele, Steffen Dingfelder, Ralf Mehrholz, Marcus Hirzel, Bianca Oehm, Marie-Louise Hertfelder

Patent number: 10976668Abstract: An illumination optical unit for EUV projection lithography serves for obliquely illuminating an illumination field, in which an object field of a downstream imaging catoptric optical unit and a reflective object to be imaged can be arranged. A pupil generating device of the illumination optical unit is embodied so that an illumination pupil results, which brings about a dependency of an imaging telecentricity against a structure variable of the object to be imaged. This dependency is such that a dependency of the imaging telecentricity against the structure variable of the object to be imaged on account of interaction of the oblique illumination with structures of the object to be imaged is at least partly compensated for. An optical system for EUV projection lithography also has an imaging catoptric optical unit alongside an illumination optical unit and can additionally have a wavefront manipulation device.Type: GrantFiled: October 10, 2019Date of Patent: April 13, 2021Assignee: Carl Zeiss SMT GmbHInventor: Joerg Zimmermann
