An apparatus for manufacturing a photonic crystal fiber preform having a plurality of holes that extend in a lengthwise direction of the photonic crystal fiber perform is disclosed. The object is activated and controlled to separate from a horizontal plane by a pre-determined distance. Zooming is performed by moving the second group of lenses G2 and fourth group of lenses G4 along an optical axis. A reject wheel 28 is disposed upstream of the outlet wheel and includes unlockable gripper means 130 which grips the vessel at a point above the flange for taking out the vessel from the drier. The union end of one pin in the plug base resists against the vertical surface of the conductor element, and a buckling edge along each of the two sides of the union end is inserted into the plug base. In a hybrid embodiment, both a fuel cell power generation array and a lead-acid battery pack cache backup array may be utilized to provide backup power for a storage subsystem.
