Abstract: A method for producing a hot-rolled steel sheet which enables predicting a temperature history of unevenness of the end face of a coil includes: measuring a surface temperature of hot-rolled strip-shaped steel; calculating a temperature history in a natural cooling state after coiling, assuming that the strip-shaped steel has been coiled without unevenness on an end face, based on the surface temperature measured in the measurement step; actually coiling the strip-shaped steel after the measurement step; scanning with a displacement meter, an end face of a coil formed in the coiling step, and deriving a size of the unevenness of the end face over a radius of the coil; and predicting a temperature history of the unevenness in a natural cooling state using: the temperature history calculated in the first calculation step; and the size of the unevenness derived in the derivation step.

Abstract: A semiconductor device that includes: a substrate having a first main surface and a second main surface opposite to each other in a thickness direction; a circuit layer on the first main surface of the substrate, the circuit layer having a first electrode layer, a second electrode layer, a dielectric layer between the first electrode layer and the second electrode layer, a first outer electrode and a second outer electrode each extending to a surface of the circuit layer opposite to the substrate; and a first resin body at each of four corners of the substrate in a plan view in the thickness direction, and wherein, in the thickness direction, a top end of the first resin body on the side opposite to the substrate is positioned higher than top ends of the first outer electrode and the second outer electrode on the side opposite to the substrate.

Abstract: A high-pressure tank is detected to rupture before the rupture of the tank with high accuracy. The pressure when the indicator obtained based on measured acoustic emission or sound is at least a threshold value is defined as a pressure just before a rupture.

Abstract: A polyamideimide resin having isocyanate groups at the terminals, wherein at least a portion of the isocyanate groups are blocked with an ether group-containing cyclic amine.
