Latest Patents

Tadanori Sano holds a patent for a method of manufacturing a copper electrical conductor. This method focuses on creating an improved conductor wire, specifically designed for use in audio and video devices. The conductor consists of copper with a high purity of at least 99.9 wt. %. The process involves forming a high-purity copper rod, which is then heat treated at temperatures ranging from 400°C to 700°C for a duration of 1 minute to 24 hours. Following this, the rod undergoes cold working with a reduction in area of at least 65%. This innovative method results in an electrical conductor wire that minimizes irregularities in electron density, thereby eliminating phase differences in high-frequency signals. As a result, it ensures clear transmission and reproduction of audio and video signals. The method also increases the residual resistance ratio of the conductor wire to at least 179, or by at least 20% compared to conventional conductors that are not heat treated. Quality control measures allow for the evaluation of the expected audio and video transmission characteristics by determining the residual resistance ratio of the manufactured conductor wire.
