In one or more of the disclosed embodiments, the number of times toggle operations of a data bus are performed at the time of a data transmission in a semiconductor storage apparatus is reduced, thereby reducing the power consumption. The representation is an MPEG compliant bit modified to reduce the number of bits. The clamping jaws have surfaces which grasp the traction element. An expansion arm moveable between a first collapsed position when the expansion section is at its first depth and an second expanded position when the expansion section is at its second depth, wherein in the second position the expansion arm is in contact with and supports the lid at its second depth is also provided. A phase winding of a motor conveys current induced by the voltage waveform, and a regulator regulates the flow of the current conveyed by the phase winding for storage as energy in a storage component.
