Disclosed herein are embodiments of a swing compensation scheme for compensating errors in a transmitter driver. The oil-feeding device for a crankshaft includes upper bearing members and lower bearing members. Preferably, a highly thermally conductive nozzle tip is removably coupled to the nozzle body and includes first and second nozzle tip melt channels that merge together before the mold gate. The microprocessor includes multiple processors associated with the caches. The reference signal has a similar format to the transmission signals and includes a portion identical to the predetermined values or repeated portion of the received signal and compares the received transmission signal and the reference signal. The slide assembly is translatable within a machine base and its motion is controlled by the piezo-electric motors.
