Abstract: A catalyst for purification of exhaust gas in which Pd-based nanoparticles and ceria nanoparticles are supported on a composite metal oxide support containing alumina, ceria, and zirconia, wherein a molar ratio (Ce/Pd) of Ce and Pd supported on the support is 1 to 8, a proximity ? between Pd and Ce is 0.15 to 0.50, wherein the proximity ? is determined, based on Pd and Ce distribution maps in an element mapping image of energy dispersive X-ray analysis, by the following formula (1): ? = ? j = 0 N - 1 ? ? i = 0 M - 1 ? ( ( I ? ( i , j ) - I ave ) ? ( T ? ( i , j ) - T ave ) ) ? j = 0 N - 1 ? ? i = 0 M - 1 ? ( I ? ( i , j ) - I ave ) 2 - ? j = 0 N - 1 ? ? i = 0 M - 1 ? ( T ? ( i , j ) - T ave ) 2 , ( 1 ) a Pd dispersity after a heat-resistance test at 1050° C. for 25 hours is 0.8% or more.

Abstract: A steel material having a chemical composition contains 0.0010% to 0.0030% C, 0.05% or less Si, 0.1% to 0.5% Mn, 0.021% to 0.060% Ti, and 0.0005% to 0.0050% B on a mass basis such that B/C satisfies 0.5 or more, whereby a resulting cold-rolled steel sheet has a microstructure dominated by ferrite with an average grain size of 10 ?m to 30 ?m, a proportional limit of 100 MPa or less, and excellent shape fixability.

Abstract: There is provided a roll coating apparatus and method for producing a coated metal strip. The roll coating apparatus presses a roll against the surface of a metal strip and coats the metal strip with a coating fluid, and is capable of adequately adjusting the pressure force of the roll so that it is uniform in the width direction of the roll, while maintaining the overall rigidity of stands that support the roll. A connecting member 15 connects an applicator roll support unit 11a in a right stand 1a and an applicator roll support unit 11b in a left stand 1b, and a connecting member movement mechanism 16a is provided between the right end of the connecting member 15 and the applicator roll support unit 11a in the right stand 1a, making it possible for the connecting member 15 to move in the direction of pressure against the metal strip.
