A phase-lock loop which includes an oscillator having an oscillator signal whose frequency is related to a received error correction signal and phase-frequency detector receiving and comparing the oscillator signal and a reference signal from the master circuit and generating the error correction signal based on the phase difference of the oscillator signal and the reference signal. The assembly includes a lower module with a top structural edge and an upper module with a bottom structural edge. The battery module further includes first and second heat conductive fins disposed in the housing that contacts the electrically non-conductive oil. The apparatus also includes a plurality of slicing blades arranged for individual rotation about one of the plurality of apertures. tuberculosis infection, or may be used for the diagnosis of tuberculosis. One bearing portion supported to the base end of the support and another bearing portion spaced apart from the bearing portion and supported rotationally on the top end of the support shaft are provided integrally to the bracket.
