A high frequency treatment instrument for an endoscope is provided. More specifically the present invention relates to a purifying method for organic electroluminescent material, organic photovoltaics material and organic thin-film transistor material. If the module fails to operate correctly at the tested speed, the integrated circuit or circuits that caused the failure are removed and replaced with new integrated circuits, and the module is retested. The keep-alive autonomic adjustment mechanism may also include the ability to autonomically enable and disable the keep-alives. The steam-emitting member comprises two annular projections provided with sectors which have different transverse dimensions and which are offset relative to one another and define a labyrinthine path.
