Oxazoline compounds having a 3,5-disubstituted-4-pyridyl group in the 2-position and a thienyl, thiazolyl or an arylphenyl group in the 4-position are effective in controlling aphids, insects and mites. A constant current circuit generates a constant current to feed through the LED. A leg extends downwardly and forwardly from a forward edge of the top plate. For accurate reproduction of digital data from a DVD under low SNR conditions, a specific Viterbi detector is used which performs maximum likelihood sequence estimation. Other exemplary technologies are also disclosed. The device further comprises a setting apparatus for driving the top swage longitudinally downward relative to the top swage’s longitudinal center axis and for driving the bottom swage longitudinally upward relative to the bottom swage’s center axis.
