Patent number: 6863968Abstract: A non-asbestos-based friction material for brakes, clutches or the like for automobiles, large-size trucks, railway cars and various industrial machines. The friction material has excellent friction and rust preventive characteristics, and attacks the plane it faces to a limited extent. The non-asbestos-based friction material is produced by forming and then curing the non-asbestos-based friction material composition comprising a fibrous base, binder and filler as the major ingredients. The composition contains at least one type of steel fibers selected from the group consisting of iron, special dead soft steel and dead soft steel, containing carbon (C) at 0.13% or less at specific contents, in the fibrous base at 1 to 50% by volume of the whole friction material.Type: GrantFiled: July 30, 2002Date of Patent: March 8, 2005Assignee: Nisshinbo Industries, Inc.Inventors: Takeo Nagata, Jun Nagashima

Publication number: 20040193776Abstract: In each embodiment of this invention, a pairing apparatus has a random pairing module which generates pairings from the first to (r1)-th rounds by the random system, and a modified Swiss pairing module which generates pairings from the (r1+1)-th to r-th rounds by the modified Swiss system. When first several matches are paired by the random system, win points are distributed to respective participating teams in accordance with their merits. For this reason, by subsequent pairings of the modified Swiss system, participating teams can be successively paired within a close merit range. Hence, the total win points (ranks) can reflect the merits. For this reason, the reverse phenomenon of merits and ranks can be suppressed without using the round-robin system.Type: ApplicationFiled: June 23, 2003Publication date: September 30, 2004Inventors: Hiroyuki Iida, Tsuyoshi Hashimoto, Jun Nagashima
