A wireless communication terminal has an air interface for interfacing the terminal to a base station, an internal power source and an external power source. In each of the inner and outer races, a one-way clutch raceway surface is formed in one axial side of a rolling bearing raceway surface. The first multiplier electrically coupled to the phase converter for performing a first operation by multiplying the delayed test wave form with the output wave form. Other aspects optimize DCT decoding computation with faster approximations where the quantization values indicate a higher degree of lossiness or noise in the DCT encoded data. The sub-assembly, which is electrically insulative, supports a lead portion of the primary winding. A slit is formed in a side face plate facing a final gear of a case side baffle plate to discharge the oil from an oil volume X in the circumference of the final gear to an oil volume Y stored in a clearance between the case side baffle plate and the transmission case, and in a clearance between the housing side baffle plate and the housing.
