摘要： A high-strength cold-rolled steel sheet having a tensile strength of 340 MPa or more, which can prevent galling, can be manufactured even if a large number of the steel sheets are continuously press-formed. This is because a surface texture thereof is con-trolled so that the surface texture includes flat areas in which a roughness profile has a deviation of ±2 μm or less from a filtered waviness curve and a dented portion having a maximum depth between 10 μm and 50 μm from the filtered waviness curve, wherein an average area of the dented portion is more than 0.01 mm2 and 0.2 mm2 or less, and an area fraction of the dented portion relative to the entire surface thereof is 5% or more and less than 20%.

摘要： There is disclosed a method for producing oxyindoles, which comprises reacting a 2-halogenophenylacetic acid or its salt with ammonia in the presence of a copper salt catalyst, and heating a mixture of the produced 2-aminophenylacetic acid or its salt and oxyindoles in the presence of an acid catalyst, to subject the 2-aminophenylacetic acid or its salt to a ring-closure reaction. According to this method, relatively readily available 2-halogenophenylacetic acids are used as a starting raw material to industrially produce highly pure oxyindoles in high yield in one pot without involving complicated steps. Further, since the amination is carried out at a temperature greatly lower than that of the conventional art, the lowering of the pH of the reaction liquid can be suppressed. Therefore, the restrictions on the specifications of the reaction apparatus, such as corrosion prevention and pressure resistance, can be mitigated.

摘要： A method for manufacturing an ultra high strength member includes heating a steel sheet at a first heating temperature within a temperature range of 700 to 1000° C.; forming the steel sheet into a shape of a member at the first heating temperature and simultaneously cooling the steel sheet; after completion of the cooling, shear punching the steel sheet into a desired shape to obtain an ultra high strength member; and after the shear punching, subjecting the ultra high strength member to a first heat treatment including heating the ultra high strength member at second heating temperature within a temperature range of 100° C. or higher, but lower than 300° C. and retaining the member at the second heating temperature for 1 second to 60 minutes, wherein the resulting ultra high strength member has a tensile strength of 1180 MPa or more.
