Abstract
A reactance adjuster includes an electrode () inducing an electric-field in an electric-field transmittable medium (), an adjusting signal generation section () outputting alternatingly a high level or a low level signal to a resonance section (), an electric-field detection section () generating an electric signal based on the electric-field in the medium (), a first electric-charge storing means (C) storing electric-charge according to the electric signal when the section () outputs a high level signal, a second electric-charge storing means (C) storing electric-charge according to the electric signal when the section () outputs a low level signal, a voltage comparator () outputting a predetermined signal based on a voltage difference between the storing means, a control section () outputting a constant voltage when the first and the second storing means (CC) are storing electric-charge and a voltage based on a predetermined signal when the storing ends.
