Disclosed herein is a processing system that can supply a material gas produced inside a material reservoir tank into a processing apparatus while generating almost no pressure loss. A pair of guide grooves 6 is formed along the upper window and guides a roller shaft 5. The connecting member can include an upper layer and a lower layer that are attached at a central attachment portion. An actuator comprising a piston is actuated within one of the liners to selectively allow and stop fluid flow. The electrotextile provides softness and at the same time the possibility of having electric connections in the material. 5 to 25 mass %, and the proportion of the component in the component is 80 to 100 mass %.
