    摘要： This invention provides a solid polymer electrolyte which is low in water absorption, from which no dopant runs out even in pressing, and which is excellent in stability in the presence of water or methanol, proton conductivity and methanol barrier properties, in which an imidazole ring-containing polymer such as a polybenzimidazole compound is doped with an acid in which at least one hydrogen atom of an inorganic acid such as phosphoric acid is substituted by a functional group having a phenyl group by blending the imidazole ring-containing polymer with the acid in a solution using a solvent such as trifluoroacetic acid, preferably at a rate of 1 to 10 molecules of the acid per repeating structure unit of a molecular chain of the imidazole ring-containing polymer, the solid polymer electrolyte.

    摘要： A rotor position estimating device includes a voltage application unit, a current detecting unit and an estimating unit. The voltage application unit is configured to apply a d-axis voltage to an electric motor including a salient-pole rotor during a stop of the electric motor. The current detecting unit is configured to detect a q-axis current flowing through the electric motor at the time when the d-axis voltage is applied. The estimating unit is configured to estimate a rotor position during a stop of the electric motor on the basis of the q-axis current detected by the current detecting unit. The voltage application unit is configured to set a voltage application time in correspondence with peak timing at which the q-axis current reaches a peak in a transitional response characteristic of the q-axis current at the time when the d-axis voltage is applied.
