  • Patent number: 8740042
    Abstract: The invention provides a friction-welded part featuring easy design as well as a method of producing said part. The friction-welded part 1 is produced by friction-welding a first member 10 and a second member 20 together. The first member 10 is made of an aluminum alloy material, having a uniform cross-section portion 11 whose cross-sectional shape and size are not changed. The second member 20 is made of an aluminum alloy material, having a uniform cross-section portion 21 whose cross-sectional shape and size are not changed. According to the invention, the uniform cross-section portions 11 and 21 are friction-welded together to form the part 1. A heat affected zone “H” caused by friction welding is formed only in the uniform cross-section portions 11 and 21. The uniform cross-section portion 11 of the first member 10, and the uniform cross-section portion 21 of the second member 20, respectively, have a cylindrical shape, preferably having the same sectional dimension.

  • Publication number: 20090305077
    Abstract: The present invention provides a friction welded part which can be easily designed, a suspension rod formed of the friction welded part, and a joining method. A friction welded part (1) is formed by friction welding a first member (10) at least whose first joining portion is formed into a cylindrical shape, and a second member (20) having an appropriate shape. The second joining portion (21) of the second member (20) is formed into a bottomed cylindrical shape corresponding to the first joining portion (10A), and the inside of the cylinder is formed into a curved surface continuing from the cylindrical inner wall portion (21C) to the bottom portion (21B), and the first joining portion (10A) of the first member (10) and the second joining portion (21) of the second member (20) are joined by friction welding.

  • Patent number: 4760023
    Abstract: [21-Leucine] human urogastrone, hUG, comprising a polypeptide represented by the specified amino acid sequence has been found to be equivalent to the known hUG which has 21-Met and is disclosed together with its syntheses. Double-stranded polydeoxyribonucleotides comprising a structural gene for expressing the hUG, a recombinant plasmid comprising a structural gene for expressing the hUG, and E. coli transformed by the recombinant plasmid are also disclosed. Thanks to the substitution of Met in the known hUG by Leu, the peptide of hUG can now be produced by a conventional or typical method in which a genetically engineered precursor fused polypeptide is cleaved by cyanogen bromide at Met in the fused polypeptide.
