Patent
FET power converter with reduced switching loss
TL;DR: In this paper, the value of the inductor is chosen with respect to the input and output voltages and frequencies of operation involved, to insure that the current polarity reverses each cycle, raising the node voltage to the level of the input voltage.
Patent
Power conversion with reduced switching loss
TL;DR: In this paper, a buck-to-dc power converter with a flywheel and an inductor is described, where the inductor current polarity reverses each cycle, raising the node voltage to the level of the input voltage, substantially eliminating turn-on losses of the first FET.

Patsy Ann Bowlds,Bruce M. Cassidy,Arthur E. Graham,Robert John Huljak,Donald Wayne Stafford,Deh C. Tao +5 more
TL;DR: Disclosed is a thermal transfer medium which comprises a mixture of a thermosetting polyimide, a thermoplastic polyimides, and graphite as discussed by the authors, and it has a steel support layer and an intermediate layer of silicon dioxide.
Patent
Intermediate layer of silicon dioxide in thermal taransfer ribbon
Patsy Ann Bowlds,Bruce M. Cassidy,Arthur E. Graham,Robert John Huljak,Donald Wayne Stafford,Deh Chang Tao +5 more
TL;DR: In this article, a thermal transfer ribbon for non-impact, thermal printing by resistive heating in the ribbon is described, where an outer layer on the steel support layer is the thermal ink.
