Dopant-Free Tungsten Electrodes In Metal Halide Lamps

View page
US Patent:
7583030, Sep 1, 2009
Filed:
Jul 21, 2004
Appl. No.:
10/895288
Inventors:
Chakrapani V. Varanasi - Dayton OH, US
Timothy R. Brumleve - Urbana IL, US
Abbas Lamouri - Aurora OH, US
Ajaypal Naruka - Twinsburg OH, US
Assignee:
Advanced Lighting Technologies, Inc. - Solon OH
International Classification:
H01J 17/20
H01J 61/18
US Classification:
313640, 313633, 313638, 313641, 313642

Flux Pinning Enhancements In Superconductive Rebacuo(Rebco) Films And Method Of Forming Thereof

View page
US Patent:
7687436, Mar 30, 2010
Filed:
Dec 1, 2006
Appl. No.:
11/565888
Inventors:
Chakrapani Varanasi - Dayton OH, US
Paul N. Barnes - West Milton OH, US
Assignee:
University of Dayton - Dayton OH
International Classification:
B05D 5/12
US Classification:
505325, 505480, 427 62
Abstract:
Nanometer-sized non-superconducting particulates in superconductive REBCO films, where RE is a rare earth metal, for flux pinning enhancement and a method of forming are disclosed. A target with a second phase material sector portion and a superconductive material portion is used in a pulse laser deposition process to form films on substrates according to the present invention. The films consist of 10-20 nm-sized precipitates. In a 0. 5 μm thick film, a transport critical current density (J)>3 MA/cmat 77K in self-field was measured. In one embodiment, magnetization Jat 77 K and 65K showed significant improvements in a composite YBCO films with fine precipitates produced according to the present invention as compared to non-doped (standard) YBCO films (>10 times increase at 9 T, 65 K).

International Classification:
H01B 12/00
H01L 39/00
H01F 6/00
B32B 9/00
US Classification:
505231, 505230, 505232, 505234, 505430, 505431, 428930, 427 62, 427 63, 29599, 1741251, 335216
Abstract:

Barrier Coatings And Methods In Discharge Lamps

View page
US Patent:
7057335, Jun 6, 2006
Filed:
Nov 10, 2003
Appl. No.:
10/703593
Inventors:
Tryggvi Emilsson - Urbana IL, US
Timothy R. Brumleve - Urbana IL, US
Chakrapani V. Varanasi - Dayton OH, US
Assignee:
Advanced Lighting Technologies, Inc. - Solon OH
International Classification:
H01J 61/35
US Classification:
313485, 313635
Abstract:
The present invention includes barrier coatings and methods for reducing or preventing chemical reaction between the discharge medium and arc tube wall material in discharge lamps. The barrier coatings comprise nitride layer exposed to the discharge medium formed from one or more of aluminum, boron, scandium, yttrium, or the lanthanides. In another aspect, the present invention includes methods of forming coatings on the inner wall of arc tubes by introducing two or more precursors into the arc tube chamber and pyrolitically reacting the precursors to form layers for the coating.
