A method for the writing and erasing of a non-volatile memory area, in which after error-free writing of the memory area, at least one release pattern is written into a predetermined subarea of the memory area. Only feeds of fuel and air are necessary for producing hot oxygen for a melting furnace and a nitrogen-enriched stream to a float bath. The auxiliary bearing may also include a first pedestal extending radially-inward from the support structure, and first and second beams extending from opposite sides of the first pedestal in a plane perpendicular to an axis of the shaft. The pacemaker then calibrates the oxygen saturation sensor based on sensor output values detected only when all three conditions are met. The spray comprises especially a propellant selected from the group consisting of dimethyl ether, diethyl ether and methylethyl ether or a mixture thereof and further a pharmaceutically acceptable lipid carrier solubilised or suspended in said propellant. Electro-osmotic flows are caused to occur due to electric double layers induced at the interface between the solution and the conductive particles by application of a voltage, thereby producing interaction among the conductive particles to displace the conductive particles and change reversibly the dispersion state of the conductive particles in accordance with the applied voltage.
