A wind-driven power source comprises a propeller-driven rotor structure and a stator structure carrying clusters of copper-wire wound ferromagnetic cores as voltage generators. The carrier matrices of the present invention can include ligands incorporated within the matrix at a predetermined concentration level. Further, a motor position-within-one-revolution deviation in the subtracted correction position deviation amount is corrected in a region in which the characteristic of torque is improved. A bezel includes on its inner periphery a female screw disposed within the clearance groove for releasably engaging with the male screw and an annular engagement convex having a stopper slope. The method identifies, by the NIC, one of several queues for storing data flows to be sent out of the host through the port based a mapping between the data flows, the queues, and a plurality of tunnels.
