The trend in the microelectronics industry, and particular that part of industry concerned with fabrication integrated circuits, is toward circuits increasingly high density devices smaller feature size. This has spurred interest several new process technologies for pattern replication. One such emerging technology ion-beam etching offers higher resolution, greater dimensional control, yield than conventional wet chemical etching. Several examples surface relief formation by illustrate...

If undetected by phase or ground overcurrent relaying methods, fallen distribution conductors high impedance faults may be a fire hazard and threat to public safety. Four promising relay schemes detect these are evaluated using both digital analog techniques one scheme was chosen for prototype construction. In the light of economic performance data, Ratio Ground Relay has been constructed installation testing on six Pennsylvania Power Light feeders.

Abstract Average particulate sulfate concentrations in air as measured from serial short-term samples collected on glass-fiber filters were consistently and significantly higher than those single long-term samples. In investigating this anomaly, we found that significant amounts of extraneous can be formed filters, presumably by oxidation atmospheric sulfur dioxide, thus leading to highly inflated values for determined The discrepancy is reduced with longer-term because the formation dioxide...

Digital fault investigations on six Pennsylvania Power and Light 12 kV distribution feeders led to the development of a prototype Ratio Ground Relay theoretically provide better detection broken conductor faults. Further assessment relay's performance was provided through analog computer tests followed by staged testing an operating feeder. Performance are described documented. These positive test results incentive monitor several PP&L feeders.
