An improved protein beverage which may provide a relatively high protein content, ranging from about 0. The required drive power is output to the drive shaft by appropriately controlling and internal combustion engine, a power split device, the electric motor and a shifting portion. Whereby a time for preparing data base by the radiowave propagation simulation can be decreased, and the radiowave monitor can be more efficient. During rework of the printed circuit board, the heat retention plate minimizes the temperature gradient between the rework site of the printed circuit board and the remainder of the printed circuit board. The LED converts the electrical signal into an optical signal and re-transmits the optical signal to the one of the plurality of ICDs. At least one ends of the plurality of reinforcement pipes are fixed to the strap bar receiving parts.
