  • Piston of internal combustion engine
    Patent number: 6357341
    Abstract: In a reciprocating piston of an internal combustion engine comprising a piston skirt having a major-thrust-side skirt portion and a minor-thrust-side skirt portion, a projected circumferential width of the minor-thrust-side skirt portion is greater than a projected circumferential width of the major-thrust-side skirt portion. Additionally, the piston skirt is dimensioned so that the minimum thickness of the minor-thrust-side skirt portion is less than the minimum thickness of the major-thrust-side skirt portion.

  • Insole part for use in manufacturing shoes
    Patent number: 5105564
    Abstract: A method of making shoes of the type having a soft sole and an insole part used in the method. The insole part is produced by cementing a thin and soft insole sheet on a hard insole base so as to be easily peeled apart and separated. The method includes using the insole part in lieu of a conventional insole, performing a conventional lasting manufacturing method, separating the insole base from the insole sheet and leaving only the insole sheet. A highly efficient manufacturing method is thus provided by using a lasting machine.
