Computational Investigation on the Effects of Arc Location in Vacuum Arc Remelting

Creator:: Soler, Miguel
Abstract:: Vacuum arc remelting (VAR) is a secondary melting process for exotic alloys. The main purpose of this process is to increase the input ingot’s physical and chemical homogeneity. This is accomplished through the application of a high current that melts the material through the emergence of electrical arcs that induce...

Investigating arc behavior in a DC vacuum arc remelting furnace using magnetic flux density measurements

Creator:: Woodside, Rigel
Abstract:: The behavior of a metal vapor plasma arc in a vacuum arc remelting (VAR) furnace is believed to contribute to the formation of defects in reactive metal and super-alloy ingots. Industry standard instrumentation, which includes electric current and voltage measurements, can asses the stability of an arc but cannot predict...

Ultralight fabric reflux tube thermal vacuum testing

Creator:: Pauley, Keith Alan
Abstract:: Five Ultra light Fabric Reflux Tubes (UFRTs) were tested in a thermal vacuum chamber at the National Aeronautics and Space Administration's Johnson Space Center in September 1994. These test articles were design and fabricated by staff at the Pacific Northwest Laboratory, operated by Battelle Memorial Institute for the United States...

Vacuum deposition of silicon monoxide for capacitors

Creator:: Lo, Joseph Ping Kwan
Abstract:: The experimental procedure for evaporating silicon monoxide together with the methods for measuring the film thickness have been investigated. The effects of various process parameters on the rate of deposition, such as source temperature and source-substrate distance, have been studied. The uniformity of silicon monoxide films deposited by this particular...

Vacuum-deposited aluminum-oxide MOS transistors

Creator:: Hwang, Yun-sheng
Abstract:: The properties of evaporated aluminum-oxide films were investigated. The characteristics of MOS devices made with single-layer aluminum-oxide films and double-layer films which were made by evaporating aluminum oxide over thermally-grown silicon dioxide as gate insulation have been investigated. Vacuum-evaporated aluminum oxide has features which are suitable for fabricating MOS devices....

Substrate noise coupling analysis in 0.18um silicon germanium (SiGe) and silicon on insulator (SOI) processes

Creator:: Pham, Hui En
Abstract:: Analysis of substrate noise coupling has been performed for a 0.18¹m lightly doped silicon germanium BiCMOS process. Techniques to minimize noise coupling in the chip and board design are presented, as well as methods for accurate modeling for substrate noise coupling simulations. Measurements from a test chip were taken to...

The effect of residue removal and burning on the growth of Festuca longifolia Thuill. and Festuca rubra L. subsp. commutata Gaud. established for seed production

Creator:: Vollmer, Gregory S.
Abstract:: Hard Fescue (Festuca longifolia Thuill.) has potential for in creased turf use but does not respond well to normal seed production management practices in Oregon. Field burning (the normal residue management practice) results in reduced seed yields in commercial hard fescue seed production fields but stimulates seed production in Chewings...

Occupational exposure characterization of vacuum pump maintenance technicians in a semiconductor manufacturing environment

Creator:: Buser, Deborah Elaine
Abstract:: In the semiconductor industry, numerous potential occupational exposures exist as a result of the diversity of chemical and physical hazards unique to integrated circuit manufacturing. The hazards associated with maintenance tasks are challenging because the sporadic nature of the tasks make exposure monitoring difficult. In particular, vacuum pump maintenance is...

Efficacy of electrolyzed oxidizing (EO) water combined with UV-C light or gas exchange on sanitization of Jalapeno pepper using Serratia marcesens as surrogate for Salmonella

Creator:: Ekundayo, Olufunmilayo R.
Abstract:: Jalapeño peppers are usually consumed raw and fresh with minimal processing. They contain antioxidants and bioactive compounds which are of human health benefits. There have been an increasing number of reports of foodborne outbreaks attributed to inaccessibility of sanitizers to Salmonella , E.coli and Listeria monocytogenes when embedded in fruit...

Measurement and scrubbing of SO₂ and NOx from boiler flue gases

Creator:: Reichel, Rolf Hubertus
Abstract:: At the Oregon State University heating plant the primary source of heat energy is natural gas with crude oil as the standby supply of fuel. In the future, as natural gas becomes a rarer commodity, more reliance will be placed on the use of the more expensive, more polluting, but...
