Latest Patents
One of Isamu Sone's latest patents is an optical-voltage sensor. This sensor features a simple structure and is capable of being formed by directly laminating highly sensitive electro-optical elements. The optical-voltage sensor includes a light source, a polarizer, a quarter wavelength plate, an analyzer, and an O/E converting portion. Two electro-optical elements are arranged adjacent to each other along a light transmitting direction between the quarter wavelength plate and analyzer. Transparent electrodes are attached to the front and back surfaces of each electro-optical element, with voltages of equal magnitude but opposite polarity applied from a power supply.
Another significant patent is related to an SF6 gas arc extinguishing electric apparatus and process. This apparatus is designed for use as a circuit breaker and contains an SF6 gas insulator and a resin insulator. Both insulators are exposed to arcs, and the resin insulator's surface is made from a polymer containing nitrogen atoms or a polyolefin resin. This design ensures excellent surface and inner arc resistance, maintaining breaking performance over an extended period.
