A magnetic gear mechanism including a simplified assembly of a magnetic flux modulating section in the magnetic gear mechanism which improves the strength thereof. The result of the handover is that the MN connects to the network through a new access router. The strap is shaped and configured to stabilize the conduit box, particularly as conduit wires are pulled therethrough. In another embodiment of the present, the annealing step is a result of providing a high forward current to the bipolar transistor while operating below the avalanche condition. The base plate has an indentation portion surrounding the through hole and disposed between the light guide plate and the through hole for shielding.
