The present invention relates to a process for the coating and water-repellent impregnation of mineral building materials, in which an architectural coating composition containing from 1 to 30 % by weight of C1-C20-alkyl-C1-C6-alkoxysilane as impregnating agent is applied to the building material. First and second motor modules are packaged within a transmission casing and are operatively connecting the input member and the output member and coaxially arranged about the axis of rotation. In an embodiment of the invention, an electrically conductive porous structure is formed on a substrate, the electrically conductive porous structure containing a plurality of pores. The second pads are disposed on the interconnection structure, and the panel-shaped component is embedded in the interconnection structure. The first memory bank corresponding to a first range of addresses.
