Patent number: 11152020Abstract: A method includes immersing a wafer in an electrolyte including a plurality of compounds having elements of a thermally stable soft magnetic material. The method also includes applying a combined stepped and pulsed current to the wafer when the wafer is immersed in an electrolyte. The wafer is removed from the electrolyte when a layer of the thermally stable soft magnetic material is formed on the wafer.Type: GrantFiled: May 14, 2019Date of Patent: October 19, 2021Assignee: SEAGATE TECHNOLOGY LLCInventors: Jie Gong, Steven C. Riemer, John A. Rice, Michael C. Kautzky

Patent number: 7687025Abstract: A method of manufacturing a component. In a preferred embodiment, the method includes enriching an element with an isotope and using the enriched element as a material of the component. A property of the first isotope being the same as a property of a second isotope and is preferably a mechanical, chemical, or electrical property. A second element can also be used as a material of the component, for instance, where the material is an alloy or a composite material. Further, the first isotope can be a lighter isotope of the element. Lightweight components may be manufactured using the method such that mobile platforms (e.g. spacecraft) can be assembled from the component(s). In other exemplary embodiments, the element can be hydrogen, lithium, boron, magnesium, titanium, or iron. Additionally, the component may carry a load. Components including isotopically enriched elements are also provided.Type: GrantFiled: November 12, 2004Date of Patent: March 30, 2010Assignee: The Boeing CompanyInventor: Brian J. Tillotson

Patent number: 5719891Abstract: A conductive element with a lateral oxidation barrier is provided for the control of lateral oxidation processes in semiconductor devices such as lasers, vertical cavity surface emitting lasers and light emitting diodes. The oxidation barrier is formed through modification of one or more layers which initially were receptive to oxidation. The quality of material directly below the oxidation barrier may be preserved. Related applications include the formation of vertical cavity surface emitting lasers on non-GaAs substrates and on GaAs substrates.Type: GrantFiled: December 18, 1995Date of Patent: February 17, 1998Assignee: Picolight IncorporatedInventor: Jack L. Jewell

Patent number: 4816088Abstract: The invention relates to a method for the deformational transformation of aluminum and its alloys comprising the steps of deforming the aluminum in the solid state and annealing the deformed aluminum at a temperature at which recrystallization occurs. The recrystallization temperature of the aluminum is raised and the grain size is minimized by adding to the aluminim 5 to 1000 ppm uranium prior to the deformation. The method is particularly applicable to the production of aluminum based sheets intended to be subjected to heating at a relatively high temperature, for example the heating which accompanies enamelling or brazing operations, where the heating operation could change the mechanical properties of the sheets.Type: GrantFiled: November 23, 1987Date of Patent: March 28, 1989Assignee: Cegedur Societe de Transformation de L'Aliminium PechineyInventors: Francois-Regis Boutin, Guy-Michel Raynaud
