Abstract: This invention provides a method for predicting a gene cluster including secondary metabolism-related genes with high accuracy, independent of information concerning core genes. Such method comprises: a step of identifying a region the gene arrangement of which is conserved in nucleotide sequence information of another genome as a gene cluster on the basis of the results of homology search conducted with the use of nucleotide sequence information of at least a pair of genomes; and a step of determining whether or not the gene cluster of interest includes secondary metabolism-related gems on the basis of the proportion of synteny-like regions within the gene cluster identified by the above step.

Abstract: In a lead mounting method of mounting, onto a principal surface of a printed board, a lead to be connected to a terminal, a flat lead is prepared which lead has a mounted part to be disposed on the principal surface of the printed board and a connected part to be connected to the terminal. The flat lead is bent into an L shape so that the mounted part and the connected part are perpendicular to each other to obtain an L-shaped lead. The mounted part of the L-shaped lead is connected and fixed onto the principal surface of the printed board by soldering.

Abstract: In a mounting mechanism of a metal plate on a printed board housed in a portable telephone or the like, a metal plate connected with a terminal portion of a cell or the like is joined to a land via solder, and a cut-out portion is provided at a joining portion of the metal plate which is joined to the land, and the total length of fillets of the solder between the land and the joining portion is extended by the cut-out portion. Accordingly, the mounting strength of a metal plate mounted to the land disposed on the printed board can be improved.
