Purpose of this study is developing of the device which can guide it and stand in line while posture control one side was blockaded thin film tare of a letter of stick (work) enter in a drum made by acrylic to an upper lining up pipe with air. The condition of an instruction and lining up of a work with some parameters was examined. Study of this year was we do modeling a floatage for a work gone on with fundamental experiment mainly for theory construction. Now we intend for a work in a pipe as fundamental experiment, confirmed the floatage condition from relation of Flow quantity/Floatage height/A pipe and a gap capacity with a work (the filling up rate).
