摘要： Provided is a positive electrode active material for a lithium ion secondary battery which combines high capacity with favorable charging/discharging cycle characteristics. In this positive electrode active material for a lithium ion secondary battery, the average value of the particle diameters of the primary particles evaluated with a scanning electron microscope is 50-550 nm, and the R value is greater than 0.420 but less than or equal to 0.460, the R value being calculated by formula (2) as follows: (2) R value=(I006+I102)/I101 on the basis of the intensity I006 calculated from the height of a peak identified as the 006-plane of an α-NaFeO2 type layered structure in X-ray powder diffraction measurement, the intensity I102 calculated from the height of a peak identified as the 102-plane, and the intensity I101 calculated from the height of a peak identified as the 101-plane.

摘要： A laminate structure includes a first layer as a substrate and a second layer provided on the first layer. The second layer is composed of a rubber composition including a rubber component, first fine particles for providing a surface with irregularity, and second fine particles for shielding UV-C light. When performing Raman mapping analysis on a first peak derived from oscillation of the second fine particles in Raman scattering spectrum obtained by Raman scattering measurement of the second layer, the second layer includes a region where an intensity of the first peak is greater in an area where the first fine particles are not present than an area where the first fine particles are present.

摘要： A method for producing a Ni- or Ti-based alloy product includes preliminarily processing a hot working material of a Ni- or Ti-based alloy after hot working into a predetermined shape; heating and holding the material at a solution treatment temperature to obtain a material held in a heated state; and cooling the material to obtain a solution-treated material. The cooling step includes placing a flow path-forming member having a space for forming a flow path for a fluid on a surface of the material held in a heated state to form a fluid flow path defined by the surface of the material held in a heated state and an inner surface of the space of the flow path-forming member; and allowing a fluid to flow in the fluid flow path so that the fluid in the flow path locally cools a part of the surface of the material.

摘要： An Fe-based amorphous alloy ribbon reduced in iron loss, less deformed, and highly productive in a condition of a magnetic flux density of 1.45 T is provided. One aspect of the present disclosure provides an Fe-based amorphous alloy ribbon having first and second surfaces, and is provided with continuous linear laser irradiation marks on at least the first surface. Each linear laser irradiation mark is formed along a direction orthogonal to a casting direction of the Fe-based amorphous alloy ribbon, and has unevenness on its surface. When the unevenness is evaluated in the casting direction, a height difference HL×width WA calculated from the height difference HL between a highest point and a lowest point in a thickness direction of the Fe-based amorphous alloy ribbon and the width WA which is a length of the linear irradiation mark on the first surface is 6.0 to 180 μm2.
