Abstract: This invention carries out highly accurate determination even on an image which is likely to cause erroneous determination. An information processing device (1) includes: a classifying section (105) that obtains an output value given in response to inputting an inspection image into a classification model generated by carrying out learning so that distances, in a feature space, between feature quantities extracted from an image group not having a noise become small; and a determining section (102) that applies, in accordance with the output value, a method for the image group not having a noise or a method for an image group having a noise to determine the presence or absence of a defect.

Abstract: There is provided a non-oriented electrical steel sheet in which, in a cross section of a base material in a sheet thickness direction, the number density N2-5 of precipitates with an equivalent circle diameter of 50 to 500 nm present in a range of 2.0 to 5.0 ?m from the surface of the base material in the sheet thickness direction is 0.30 pieces/?m2 or less, and the relationship between the number density N2-5 and the number density N0-2 of precipitates with an equivalent circle diameter of 50 to 500 nm present in a range from the surface of the base material to 2.0 ?m satisfies Formula (1): (N2-5)/(N0-2)?0.5??Formula (1).

Abstract: A non oriented electrical steel sheet consists of a silicon steel sheet and an insulation coating. The silicon steel sheet includes an internally oxidized layer containing SiO2 in a surface thereof, an average thickness of the internally oxidized layer is 0.10 to 5.0 ?m, and a Vickers hardness in the internally oxidized layer is 1.15 to 1.5 times as compared with a Vickers hardness in a thickness central area.

Abstract: A hot rolled steel sheet is for a non oriented electrical steel sheet, wherein vickers hardness at the widthwise edge is 180 Hv or more, a value obtained by subtracting a vickers hardness at the widthwise center from the vickers hardness at the widthwise edge is 10 to 100 Hv, ductile brittle transition temperature at the widthwise edge is 0° C. or less, a value obtained by subtracting the ductile brittle transition temperature at the widthwise edge from a ductile brittle transition temperature at the widthwise center is 10 to 100° C., and a value obtained by subtracting a sheet thickness at the widthwise edge from a sheet thickness at the widthwise center is 50 ?m or less.

Abstract: A new artificial veneer resembling expensive natural wood veneers can be manufactured by a new method from an inexpensive raw log, wherein a wood-meal containing veneer is first obtained by slicing in quartersawn grain direction a primary artificial flitch of many material veneers of the inexpensive raw log stacked and bonded with a wood-meal layer interposed between them, and many of the wood-meal containing veneers are stacked and bonded, with the material veneers alternately interposed as they stand or as further processed, into a secondary curved artificial flitch, which is sliced in flatsawn grain direction into the new artificial veneers presenting a grain pattern similar to that of the expensive wood with minutely raised and recessed uneven surface at simulated porous zones by the wood-meal containing veneers.

Abstract: A composition for forming inorganic hardened products, which comprises a precursor for forming TSH, gypsum and a cement material selected from the group consisting of Portland cement, blast furnace slag and a mixture thereof, the amount of each ingredient satisfying the following relations by weight:1/0.2>TSH/Cement material>1/51/0.1>Precursor/Gypsum>1/1wherein TSH is the theoretical amount produced by the reaction of the TSH precursor and gypsum, and a process for producing inorganic hardened products from the composition.

Abstract: A process of producing calcium aluminate monosulfate hydrate by reacting a mixture of a lime component, an alumina component, a calcium sulfate component, and water at a temperature of from about 100.degree. C. to about 200.degree. C.By the process of this invention, the aimed product having a high purity is obtained at a high yield without need of high temperature for the reaction. The product obtained is useful as building materials.

Abstract: A two-stage process for producing a three-component graft copolymer of 1,2-polybutadiene, glycidyl methacrylate and a second monomer. By first reacting glycidyl methacrylate on the polymeric substrate and then reacting the second monomer to form a non-crosslinked graft copolymer, high curing rates are obtained. By forming a solvent solution of the grafted product, an epoxy hardener and a radical polymerization initiator, a varnish suitable for forming dielectric prepregs is obtained.
