A HGA includes a suspension, a seed layer formed on a PZT holding region of a flexure of the suspension and a piezoelectric element deposited on the seed layer. Generally, the aluminum strip is uncoiled, passed through a preheating unit, two extrusion heads, a post-heater, an air quench, a lubricator, and then it is recoiled. The data within the memory cell is erased by applying a first voltage to the control gate, applying a second voltage to the source, applying a third voltage to the drain and applying a fourth voltage to the substrate. The server sends the curve information to a client. The mat also comprises means for lifting, including passages through which chains or cable may be threaded, lifting shackle assemblies or pear link assemblies. The invention further relates to compositions prepared from such modified alkyd compositions.
