An electroconductive fiber, a method of manufacturing an electroconductive fiber, and a fiber complex including an electroconductive fiber are provided, the electroconductive fiber includes an electroconductive polymer, an elastic polymer that forms a structure with the electroconductive polymer, and a carboneous material on at least one of the electroconductive polymer and the elastic polymer. The composition exhibits extremely high stiffness while maintaining high impact strength. Thus, the sintered resistor and dielectric can be prevented from being softened and melted when the after-lamination substrate is fired. In accordance with predefined workflow definitions, intersectional workflow definitions and extended workflow definitions corresponding to a mail flow are selected and displayed. The control unit determines a head position for the highlight reproduction period which includes a reproduction position of the moving image signal when the switching to the normal reproduction mode is instructed, as the reproduction start position. A process is also described for determining offsets of measuring instruments, in particular of measures with a null or constant mean value.
