A workpiece handler and alignment assembly. The notification module is configured to inform a user of information. The compressible bladder extends at least partially around the gas spring piston and at least partially defines a bladder chamber. New HDACTDAC inhibitors and aggresome inhibitors are also provided as well as synthetic methodologies for preparing these compounds. A thin film EL device of the present invention uses, as a luminescent layer, a charge-transport luminescent material that has, within a molecule, a portion contributing to charge transport and a portion contributing to luminescence where at least two molecular orbitals contributing to luminescent transition are localized.
