摘要:
In a personal authentication medium issuing apparatus, a main image information is input and whether a personal authentication medium on which synthesized image information having sub-information embedded in the main image information is checked or not is determined based on the state of the input main image information. Further, synthesized image information having sub-information embedded in an invisible state in the main image information which is set in a visible state is formed, a personal authentication medium is formed by printing the synthesized image information on a recording medium and the thus formed personal authentication media are sorted into personal authentication media determined to be completely formed and personal authentication media determined to require a checking process.

A method of manufacturing an improved conductor wire, especially for use as wiring in audio/video devices is disclosed. The conductor consists of copper having a high purity of at least 99.9 wt. %. High purity copper starting material is formed as a rod which is then heat treated at a temperature in the range of 400.degree. C. to 700.degree. C. for 1 minute to 24 hours. The heat treated rod is then cold worked with a reduction in area of at least 65%. This method provides an electrical conductor wire which avoids irregularities of electron density and thereby eliminates phase differences in a high frequency signal, such as an audio or video signal, passing through the wire to obtain clear transmission and reproduction of an audio sound or video image. The method of the invention increases the residual resistance ratio of the conductor wire to at least 179 or by at least 20% as compared to a conventional conductor which is not heat treated according to the invention. Finally, in a quality control method, the expected audio and video transmission characteristics of a manufactured conductor wire can be evaluated by determining the residual resistance ratio of the conductor wire.
