Sample carriers for use in Transmission Electron Microscopes and freely commercially available have the form of a gauze with a strengthening edge. The methods use multiple vessels to perform coil shooting. The one or more memory cells may have voltage values respectively set to a first threshold voltage or a second threshold voltage. The NTSCPAL converter accepts a stream of data from the primary composite video module and the secondary video source module and converts it into Composite Baseband Video, YPrPb Component Video, YC Video or RGB Video. The surface of the semiconductor substrate is wet oxidized again where it is not covered by the mask to form a second layer of gate oxide under the first gate oxide layer in the high voltage active area.
