Latest Patents

Yamaguchi's latest patents include an "Electrical power cable underground laying depth measuring method." This method determines the underground-laying depth of an electric power cable based on various data, including temperature data of the cable, ambient temperature, calorific power, thermal resistivity of the surrounding soil, and radiation thermal resistivity of the cable's surface. The ambient temperature is defined as the temperature of a location unaffected by the heat generated by the cable. Another notable patent is the "Optical-fiber cable incorporated longer-sized subaqueous unit." This invention features optical fiber units arranged within or outside a plastic sheath surrounding the core body of a longer-sized subaqueous unit, such as a power cable core or water supply tube. Each optical fiber unit consists of an optical fiber housed in a metal pipe, which is coated with a plastic material that has a higher melting point than that of the plastic sheath. Additionally, armoring iron wire bundles are included outside the plastic sheath to prevent buckling in the optical fiber units.
