A method of producing a conductive belt composed of a base resin containing polybutylene naphthalate resin at not less than 50 mass % nor more than 100 mass % and 1 to 3 mass % of carbon nano-fibers having a DBP oil absorption amount at not less than 150 ml100 g. The information may be targeted to those consumers who have a precisely formulated need for the information. The selector switch may also include a circuit defining a positive feedback loop controlling the two analog switches. 1 eV, a Ge active channel layer on the bottom barrier and having a valence band offset relative to the bottom barrier that is greater than 0. The wall has an interior wall side and an opposing exterior wall side.
