A self-replicating monolayer system employing polymerization of monomers or nanoparticle ensembles on a defined template provides a method for synthesis of two-dimensional single molecule polymers. The purging composition exerts a satisfactory purging or cleaning effect, but little abrasion effect, thus avoiding any abrasion of machine internal components by purging. Foams of various metals, such as aluminum, titanium, nickel, copper, iron, zinc, lead, silver, gold, platinum, tantalum, and alloys based on these metals, may be used. The stacked cell may be disposed along the first plane. Preferably, the capacitor pre-charge test is performed when the ignition is switched ON and the capacitor discharge test is performed when the ignition is switched OFF. An antenna signal generation circuit generates the antenna signal and asserts the antenna signal on the antenna circuit.
