Abstract: A power generation device equipped with: two disk-shaped rotors that are fixed to a rotary shaft; a field system that has an even number of magnetic poles that are arranged on the same circumference, said magnetic poles comprising permanent. magnets that are fixed to the rotors in such a manner that the magnetization directions of the magnets are parallel to the axis of the rotary shaft with the directions being alternately arranged; and a stator that comprises coil substrates on which conductive patterns are formed so as to cross magnetic fluxes generated by the permanent magnets when the rotors rotate. Multiple conductive patterns corresponding to the number of phases are disposed in the stator, and electric power generated for each phase can be independently output.

Abstract: An electrode module includes a working electrode, a counter electrode, a reference electrode and a well (container) for retaining an electrolytic solution and is used in electrochemical measuring instruments. This electrode module is produced by integrating the well with at least one of the working electrode, the counter electrode and the reference electrode. This integrated electrode includes a chip-like electrode having a thin membrane of an electrode material formed on the surface of a chip-like base metal. This chip-like electrode is disposed on and integrated with the bottom of the well in a detachable manner. There is provided the compact, low price electrode module of high repetition use efficiency with no need of maintenance and having easy handling.
