The invention refers to novel propenecarboxylic acid amidoxime derivatives furthermore N-oxides andor geometrical isomers andor optical isomers andor pharmaceutically suitable acid addition salts andor quaternary derivatives thereof. The bilayer has a first layer including at least one electrically conductive polymer doped with at least one non-fluorinated polymeric acid and at least one highly-fluorinated acid polymer. A bounding box comprising the marked region is determined. Thus, the adhesion metal layer on the separation channels is only heated once. One terminal of the fluctuation detection capacitor is set to a fixed electric potential. Thus, the toilet tank can provide a two-stage flushing function, so as to regulate the water outlet rate of the toilet tank, thereby saving the resource and energy.
