Abstract: Provided is an ultra-high-strength steel sheet having a component composition that includes specific amounts of each of C, Mn, and Al and a remainder of iron and unavoidable impurities, and in which the amounts of each of P, S, and N among the unavoidable impurities are limited to a specific amount. The ultra-high-strength steel sheet includes 2 area % or more of a region having a structure that includes 90% or more of martensite and 0.5% or more of residual austentite by area ratio relative to the entire structure, the local Mn concentration in said region being at least 1.1 times that of the Mn content of the entire steel sheet. The ultra-high-strength steel sheet has a tensile strength of 1470 MPa or more.

Abstract: A door beam includes an aluminum alloy extrusion body extended in a longitudinal direction and having a pair of webs and a pair of flanges to be positioned on an inner side and an outer side in a width direction of a vehicle body. The pair of webs connect the pair of flanges at joint portions of each of the pair of webs such that the pair of webs and the pair of flanges form a closed cross section in a direction perpendicular to the longitudinal direction, and the pair of webs do not have a welded portion.

Abstract: The multilayer wiring film which is provided with a wiring layer that is formed of Cu or a Cu alloy and has an electrical resistance of 10 μΩcm or less and a Cu—X alloy layer that contains Cu and an element X and is arranged above and/or below the wiring layer, and wherein the element X is composed of at least one element selected from the group X consisting of Al, Mn, Zn and Ni, and the metals constituting the Cu—X alloy layer have a specific composition. The multilayer wiring film is able to provide a multilayer wiring film which has low electrical resistance and is free from film separation during the formation of a SiOx film by a CVD method, said SiOx film serving as an interlayer insulating film, and which is also free from an increase in the electrical resistance even if subjected to a high-temperature heat treatment that is carried out at 400° C. or higher.

Abstract: A method for reducing gel in a polymer kneaded compound flowing in a polymer flow duct includes flowing a polymer kneaded compound in a polymer flow duct to a gel reduction mechanism including a gel reduction member having one or more through holes defining a squeezing flow path having a flow path cross-sectional area smaller than the polymer flow duct. The squeeze ratio S1/S2 of the squeezing flow path is 25 to 177.8, where S1 is a flow path cross-sectional area of the polymer flow duct and S2 is a sum total of flow path cross-sectional area of the squeezing flow path, to generate an extensional flow in the kneaded compound.

Abstract: Rolling resistance is appropriately and easily evaluated at an arbitrary temperature of a tire. When a phase difference between a load applied to the tire and a variation in position of the drum is derived for a reference tire, the phase differences δ are derived at a plurality of temperatures within a range from an initial temperature to an atmospheric temperature in a process in which a temperature of the reference tire that reached the initial temperature higher or lower than the atmospheric temperature by heating or cooling approaches the atmospheric temperature from the initial temperature. The phase difference corresponding to a temperature of a tire to be evaluated among the phase differences δ derived for the reference tire at the plurality of temperatures and the phase difference derived for the tire to be evaluated are compared, thereby evaluating rolling resistance of the tire to be evaluated.
