Latest Patents
Tanno's latest patents include advancements in current/voltage non-linear resistors. One notable patent describes a current/voltage non-linear resistor that comprises a sintered body predominantly made of zinc oxide (ZnO). This unique resistor features an electrode on one surface and an insulating material on the opposite surface. The composition also incorporates auxiliary components such as bismuth (Bi), cobalt (Co), manganese (Mn), antimony (Sb), nickel (Ni), and aluminum (Al) in specific molar ratios. For instance, Bi2O3 is present at 0.3 to 2 mol %, Co2O3 at 0.3 to 1.5 mol %, and MnO between 0.4 to 6 mol %. The patent also highlights the presence of a Bi2O3 crystalline phase, which should represent at least 80% of the total Bi2O3 phase within the sintered body.
In another patent, Tanno illustrates a sintered body designed for non-linear resistance characteristics, where zinc oxide remains the principal component. The auxiliary compositions are carefully calibrated, containing between 0.05 to 10 mol% of Bi2O3, Co2O3, Sb2O3, MnO, and NiO. Furthermore, the composition emphasizes a controlled ratio of Bi2O3 to NiO and MnO to Sb2O3, which is crucial for maintaining the desired electrical properties.
