Provided is a wire rod for an I-type oil ring, which includes right and left rail portions and a web portion connecting the rail portions, which has an oil hole or a molten through hole formed in the web portion, and which has a circumscribing circle diameter of 10 mm or less in its transverse contour. The molten through hole has such a remolten portion formed on its exit side as encloses the exit of the molten through hole. The remolten portion exceeds such a molten portion in the transverse section along the center of the molten through hole as is formed in the molten through hole, and is formed to have 200 μm or less from the outer circumference of the molten through hole and 100 μm or less in the depth direction of the molten through hole.

An improved placing method and placing apparatus are provided for placing conductive balls in a predetermined pattern onto a base unit. In the placing method for placing balls having conductivity in a predetermined pattern onto one surface of the base unit, an arrangement member has one surface, another surface opposite to the one surface of the arrangement member and positioning openings, wherein the positioning openings are arranged corresponding to the pattern such that the openings are through from the one surface to the another surfaces of the arrangement member so that the balls are inserted therein. The another surface of the arrangement member is positioned opposite to the one surface of the base unit. The arrangement member has two or more line members of which the core axes are substantially aligned. The transfer device is arranged in a manner that the line members are substantially in a horizontal position to contact with the balls supplied to one surface of the arrangement member, and then the transfer device is horizontally moved with respect to the one surface of the arrangement member. Then, the balls are placed on the one surface of the base unit through the positioning openings.

A gene coding for a peptidoglycan recognition peptide (PGRP) is cloned, a recombinant vector into which said gene is introduced is obtained, and a transformant transformed with said recombinant vector is cultivated, thereby producing the PGRP in large amounts at high purity.

摘要:
A novel water-soluble enzyme protein being composed of three heterogeneous subunits and having nitrile hydratase activity was separated and purified from the bacterium of genus Rhizobium. The nucleotide sequence of the gene encoding the protein was determined; using the transformant transformed with the expression vector having the nucleotide sequence, the protein was expressed; by reacting the transformant with a nitrile in a culture broth, the corresponding amide was produced.Via the use of a culture broth containing the transformant described above or the protein itself, a nitrile can be efficiently converted into the corresponding amide.
