Latest Patents
Sugiyama's latest patents focus on limited current type oxygen sensors. The first patent describes an oxygen sensor that comprises an oxygen ion conductive solid electrolyte, a detection element with a positive and negative electrode, and a heater element. The design includes a negative electrode installed on a wall that communicates with a small hole, which restricts the amount of oxygen that can diffuse through. The porous positive electrode and heater are embedded within the solid electrolyte layers.
The second patent also pertains to a limited current type oxygen sensor. This invention features a solid electrolyte element made from materials with high oxygen-ion conductivity, such as yttria-stabilized zirconia. The electrodes are formed by calcining a mixture of small ceramic particles and fine precious metal particles. A cover is provided over the second electrode, which includes diffusion orifices that allow ambient gas to reach the electrode. The sensor determines the oxygen content of gases by applying different voltages to generate corresponding currents associated with the oxygen ions flowing through the electrolyte element.
