Abstract: A synthetic resin skin material and a manufacturing method thereof, the synthetic resin skin material including, in this order: a base fabric; a thermoplastic resin layer having a storage elastic modulus at 160° C. of 2,000,000 Pa or less measured in accordance with JIS K 7244 (1998); and a skin layer containing a urethane resin, wherein the synthetic resin skin material has recesses at a side of the skin layer, the recesses having a depth, in a thickness direction of the synthetic resin skin material, that extends from the skin layer as far as an inner part of the thermoplastic resin layer, past a boundary that is present between the skin layer and the thermoplastic resin layer at a non-recessed region.

Abstract: A synthetic resin skin material composite, including: a urethane resin skin material including a urethane resin skin layer provided at one surface of a substrate; and a cushion layer that is placed at a surface on an opposite side of the substrate from the surface of the urethane resin skin material at which the urethane resin skin layer is provided; in which the urethane resin skin material has recesses at a side of the urethane resin skin layer, and each of the recesses has a depth in a thickness direction of the synthetic resin skin material composite, such that the recesses extend from the urethane resin skin layer into the cushion layer beyond an interface between the urethane resin skin material and the cushion layer that is present in a region without a recess, as well as a method of producing a synthetic resin skin material composite.

Abstract: A hexagonal crystal ferrite magnetic powder having high magnetic characteristics while having a small particle volume and a high specific surface area is provided, and a high-density magnetic recording medium using the powder. A method for producing a hexagonal crystal ferrite formed using a glass crystallization method includes the steps of: mixing a glass matrix with raw materials including iron, bismuth, a divalent metal (M1), a tetravalent metal (M2), any one kind (A) of barium, strontium, calcium, and lead, and at least one kind of rare earth element (represented by R) having a mole equal to or less than that of the iron; heating the mixed raw material to obtain a glass body; quenching the glass body, pulverizing the glass body, and performing a heat treatment, and washing the glass body after the heat treatment with an acid solution.

Abstract: There is provided a steel pipe for steam injection having high yield stress even at 350° C. The seamless steel pipe for steam injection according to the present invention has a chemical composition comprising, by mass percent, C: 0.03 to 0.08%, Si: 0.05 to 0.5%, Mn: 1.5 to 3.0%, Mo: more than 0.4 to 1.2%, Al: 0.005 to 0.100%, Ca: 0.001 to 0.005%, N: 0.002 to 0.015%, P: at most 0.03%, S: at most 0.01%, and Cu: at most 1.5%, the balance being Fe and impurities. The seamless steel pipe is manufactured by being water cooled after hot working and by being quenched and tempered.

Abstract: A molding die includes a fixed die, a movable die movable toward and away from the fixed die, a first slide core slidable in sliding engagement with the fixed die, and a second slide core having a presser for pressing the first slide core when the second slide core is held in pressing contact with the first slide core. The fixed die, the movable die, the first slide core, and the second slide core jointly define a cavity for molding a product. The presser includes a reactive force plate for producing reactive forces against the pressure of a molten material introduced into the cavity.
