The present invention is related to valves for the controlling the flow of media. The breather device includes a breather tank arranged independently between the engine intake system and the engine exhaust system on the rear side of a cylinder assembly of the engine above a crankcase thereof; and a plurality of breather pipes connecting the breather tank to the engine and the engine intake system. A character line to which an appropriate tag may not be given in the tagging modification part is output to an indecisive tag estimation part where an appropriate tag is estimated and is given with reference to a tag adjacent the character lines. 5 \u03bcm-10 \u03bcm thick edge process-induced degradation layer. The technique can adjust the coefficient based on the selected character to obtain a modified coefficient. The humidifier also includes a first passage which allows gas for flowing from one end of the peripheral apertures to the other end thereof serving as an inlet and an outlet, and a second passage which allows gas for flowing from one end to the other end of the bunch of the hollow fiber membrane.
