An object of the present invention to enable easy display of a virtual object toward a direction desired by a user, when performing a superimposed display of the virtual object in a captured image containing an augmented reality marker. Optionally, the wireless precision position tracking device is configured to be worn by a user. Monitor data related to the lot processing is defined. The smoothing artifact produced by the proposed method is much less than some known algorithms described above, but the computational complexity of the proposed method is low. or less while uncoiling the coil; correcting the shape of the steel strip using a correction rolling mill; removing oxide films formed on surfaces of the shape-corrected steel strip by injecting water jets to the surface; and drying the steel strip free of oxide films and winding the steel strip. The coolant distributing device includes a coolant relay section, an inlet conduit member, an outlet conduit member, and a transmission cooling conduit member, and supplies a portion of the coolant discharged from the water pump to a highest portion of a water jacket of the transmission device, and discharges the water from a lowest portion of the water jacket.
