Address translation between various peripheral bus interfaces is provided through a bus interface device. The differential signaling system comprises one or more cable pairs for carrying signals, one or more differential drivers for providing signals to the one or more cable pairs, and one or more differential receivers, the one or more differential receivers being coupled to the one or more differential drivers via the one or more cable pairs. The columnar microstructure extends through the entire thickness of the multilayer structure to thereby exchange decouple the magnetic layers as well as the spacer layers. The first sliding element has a first pressing portion received in the first space, and the second sliding element has a second pressing portion received in the second space. When the drive shaft is forwardly rotated, the forward rotation belt is placed in a tensioned state, and the reverse rotation belt is switched to a relaxed state.
