A method is disclosed for the induction of a suitable band gap and electron emissive properties into a substance, in which the substrate is provided with a surface structure corresponding to the interference of electron waves. It uses a modified Z-coder to code the zeronon-zero significance function and Huffman coding for the non-zero coefficients themselves. A deduplication module executing computer instructions stored in memory determines if the data pattern corresponding to the CF tag is previously stored in the removable storage device. The intermediate wiring portion is wired to pass around a vertical conduction terminal. Accordingly, a faded image input to the input unit may effectively be compensated.
