The present invention relates to a stable storable composition for the chemical grafting of at least one filler comprising a hydroxyl group, onto a polymer. This device includes a cylinder block; a chamber formed in the cylinder block and having first and second ends; a piston mounted for movement and positioned in the chamber; a detecting device mounted adjacent the first end of the chamber; and a hose having first and second ends with the first end in fluid communication with the second end of the chamber. The first and second differential coils smooth the DC current on a DC bus in the motor drive, and the first and second common-mode coils suppress common-mode voltages in the motor drive. The different collector widths produced as a result thereof are influenced by the outdiffusion of the dopant of the buried layers by other substances. The first transparent conductive stripes and the second conductive stripes are arranged in patterns such that the transparent conductive film has an anisotropic impedance.
