PURPOSE:To perform safe and sure positive and negative switching, by supplying a firing pulse to a negative thyristor bridge through specific order after turning off a positive thyristor bridge. CONSTITUTION:An AC power source is applied to thyristor bridges 3A, 3B through a transformer to supply ...

PURPOSE:To reduce the number of components, and to decrease its cost by turning ON and OFF a single transistor at the times of outputting of positive and negative voltages, and selectively switching to output it. CONSTITUTION:A positive/negative voltage output switching circuit is connected to the...
By focusing on the unique species-dependent difference in the methional activity, we could reveal the mechanism of the positive and negative modulation in T1R1. As methional has a pleasant meaty and soup-like flavor25, its aroma has been reported to evoke an umami sensation via a cross-modal...
But this is but one possible case of negative priming . There are other ways in which negative priming might occur, and there are several varieties of positive priming as well. All these possibilities were explored in the present experiment.关键词:...
摘要: A near-IR metamaterial having a tunable index of refraction from negative, through zero, to positive values has been proposed. Liquid crystal layers are incorporated both as a superstrate and a substrate onto a conventional NIM. Tuning the permittivity of...
