A method, article of manufacture, and apparatus for processing data. The device includes a first interlayer insulating film on a semiconductor substrate; a contact pad spacer on the first interlayer insulating film; and a contact pad in the first interlayer insulating film and the contact pad spacer. Mixtures of polymers comprising at least two polymers which are different from each other, at least one of which is a graft stereoblock polymer as defined above, and their uses, are also described. A keyboard and mouse input is included for inputting control signals to operate the processing means and the computer program or for altering control parameters of same. Charge is transferred between each respective cell and an associated energy storage device by sequentially coupling the storage device with different cells, such that the energy in each of the cells is transferred from cells having a higher potential energy to cells having a lower potential energy through the energy storage device. The server 4 provides a first encoded performance data to the personal computer 2, and the personal computer 2 decodes the received first encoded performance data.
