Abstract: A system performs either inference using a first model or inference using a second model and a third model according to accuracy of at least one model of the first to third models and, upon the inference, generates or updates recipe properties data that is data indicating an association between a manufacturing method recipe for a material and a material property/properties. The first model is a model to which a manufacturing method recipe dataset indicating a manufacturing method recipe is input and from which a material properties dataset indicating a material property/properties is output. The second model is a model to which a material characteristics dataset indicating a material characteristic(s) is input and from which a material properties dataset is output. The third model is a model to which a manufacturing method recipe dataset is input and from which a material characteristics dataset is output.

Abstract: A honeycomb structure includes: a honeycomb structure body including a plurality of cells defined by a partition wall and serving as a through channel of fluid; and a plugging portion to alternately plug open end parts of the plurality of cells on one side as an inflow side of the exhaust gas and open end parts on the other side as an outflow side of the exhaust gas. The partition wall is loaded, on the side of the outflow cells, with an oxidation catalyst made of a transition metal oxide at least including Fe and Mn to oxidize NO gas or an oxidation catalyst made of a transition metal oxide loaded at CeO2 and at least including Fe and Mn to oxidize NO gas. The loading amount of the oxidation catalyst is 5.0 g/L or more and 50 g/L or less.

Abstract: A voltage-nonlinear resistor element 10 includes a voltage-nonlinear resistor (referred simply as “resistor”) 20 and a pair of electrodes 14 and 16 between which the resistor 20 is interposed. The resistor 20 has a multilayer structure including a first layer 21 composed primarily of zinc oxide, a second layer 22 composed primarily of zinc oxide, and a third layer 23 composed primarily of a metal oxide other than zinc oxide. The second layer 22 is adjacent to the first layer 21 and has a smaller thickness and a higher volume resistivity than the first layer 21. The third layer 23 is adjacent to the second layer 22.

Abstract: A voltage nonlinear resistive element 10 includes a resistor 14 containing a joined body 12 in which a zinc oxide ceramic layer 12a composed mainly of zinc oxide and having a volume resistivity of 1.0×10−1 Ωcm or less is joined to a bismuth oxide layer 12b composed mainly of bismuth oxide, and a pair of electrodes 16 and 18 disposed on the resistor 14 such that an electrically conductive path passes through a junction between the zinc oxide ceramic layer 12a and the bismuth oxide layer 12b. In this element 10, the zinc oxide ceramic layer 12a of the joined body 12 has a lower volume resistivity than before. This can result in a lower clamping voltage in a high-current region than before.
