A positioning structure is applied to an electrode device, which includes a movable component and an elastic element. The outer layer is compressed to wrap around an aramid fiber or an ultra-high-molecular-weight polyethylene fiber and a core of synthetic fiber rope with molecular malleability, e. The auxiliary pattern transmits the exposing light in an opposite phase with respect to the semi-shielding portion and the transparent portion and is not transferred through exposure. Input may be provided to identify misrecognized strokes and a correct terminal production, or symbol corresponding to the misrecognized strokes. A user may generate personalized reports based on aggregated historical data based on various user-defined factors. A class changeover unit classifies each TFC based upon amount of multiplexed transport data of each transport channel, decides the class of a TFC to be selected, based upon a transmission power value, and selects a TFC from the class decided.
