Title: Innovations by Inventor Hideaki Yagi
Introduction
Hideaki Yagi is an acclaimed inventor based in Aichi, Japan, renowned for his significant contributions in the field of sensors and gas concentration technologies. With a remarkable portfolio of 13 patents, Yagi continues to push the boundaries of innovation.
Latest Patents
Among Hideaki Yagi’s latest patents are two groundbreaking inventions. The first is a sensor element and gas sensor which features a flat limiting-current design. This sensor includes a solid electrolyte substrate along with both a negative and a positive electrode located on the same side of the substrate. It operates by applying a voltage of 0.8 V between the electrodes to determine oxygen concentration. A key innovation within this sensor is that the ratio of the negative electrode area to the positive electrode area is set at 1:2, which effectively reduces the element resistance to 74% in comparison to configurations where both electrodes are of equal area. This design enhancement improves the measurement accuracy of the flat limiting-current sensor.
The second invention is an oxygen concentrating apparatus that incorporates an output variable type compressor. This apparatus is designed to supply oxygen-concentrated gas either continuously or synchronized with the timing of inhalations. In synchronous operation, the compressor operates at a reduced output compared to continuous supply, optimizing the delivery of oxygen. Additionally, during the exhalation period, the supply quantity of oxygen-concentrated gas is set to zero, ensuring efficiency in oxygen management.
