Publication number: 20130270834Abstract: A generator (5) for a wind turbine (1) and a wind turbine (1) are disclosed. The generator (5) comprises a rotor (3) configured to rotate about a rotational axis, and at least one stator (4) arranged next to the rotor (3), each stator (4) comprising at least one flux-generating module (9) facing the rotor (3) but spaced therefrom. The flux-generating module(s) (9) is/are mounted on a stator support structure (7, 10). The stator support structure (7, 10) defines a pre-loaded spring force acting against magnetic forces occurring between the rotor (3) and the flux-generating module(s) (9) during operation of the generator (5). The preloaded spring force is adjustable, e.g. by means of a piston arrangement (17). Thereby it is possible to maintain a preloaded spring force which is capable of acting against the magnetic forces occurring between the rotor (3) and the flux-generating module(s) (9), even if operating conditions are changed.Type: ApplicationFiled: January 5, 2011Publication date: October 17, 2013Applicant: VESTAS WIND SYSTEMS A/SInventors: Michael Staghøj, Gerner Larsen, Niels Christian Olsen, Frank Møller Hansen

Publication number: 20120280360Abstract: The invention relates to a semiconductor device and a method of manufacturing an electronic device. A first conductive layer (first metal interconnect layer) is deposited. There is an insulating layer (first intermetal dielectric) layer deposited. A resistive layer is deposited on top of the insulating layer and structured in order to serve as a thin film resistor. A second insulating layer (second intermetal dielectric) is then deposited on top of the resistive layer. A first opening is etched into the insulating layers (first and second intermetal dielectric) down to the first conductive layer. A second opening is etched into the insulating layers (first and second intermetal dielectrics) down to the first conductive layer. A cross-sectional plane of the second opening is arranged such that it at least partially overlaps the resistive layer of the thin film resistor in a first direction.Type: ApplicationFiled: May 3, 2012Publication date: November 8, 2012Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Christoph Andreas Othmar DIRNECKER, Leif Christian OLSEN

Patent number: 7625807Abstract: The present invention facilitates semiconductor fabrication by maintaining shape and density of an etch stop layer (206) during trench fill operations. The shape and density of the etch stop layer (206) is maintained by forming a protective alloy liner layer (310) on the etch stop layer (206) prior to trench fill operations. The protective alloy liner (310) is comprised of an alloy that is resistant to materials employed in the trench fill operations. As a result, clipping and/or damage to the etch stop layer (206) is mitigated thereby facilitating a subsequent planarization process that employs the etch stop layer (206). Additionally, selection of thickness and composition (1706) of the formed protective alloy (310) yields a stress amount and type (1704) that is applied to channel regions of unformed transistor devices, ultimately providing for an improvement in channel mobility.Type: GrantFiled: February 23, 2007Date of Patent: December 1, 2009Assignee: Texas Instruments IncorporatedInventors: Manuel A. Quevedo-Lopez, James J. Chambers, Leif Christian Olsen
