Abstract: A wiring member includes a wiring body and a pattern. The wiring body includes a plurality of wire-like transmission members and a base material. The plurality of wire-like transmission members are fixed to the base material in an aligned state, and the pattern is provided on the wiring body. The pattern makes a two-dimensional position of at least a part of a portion related to the base material recognizable in the wiring body.

Abstract: A vehicular suspension system is provided which includes upper and lower arms connected to a vehicle body in such a manner as to pivot in an up-and-down direction. The upper arm and the lower arm retain upper and lower portions of a knuckle, respectively. The suspension system includes retention mechanisms for retaining the upper and lower arms in such a manner as to allow the upper and lower arms to shift in a lateral direction of the vehicle body, and conversion mechanisms for converting pivotal movements of the upper and lower arms in the up-and-down direction into displacements of the upper and lower arms in the lateral direction of the vehicle body.

Abstract: A vulcanizable nitrile rubber composition comprising 100 parts by weight of a nitrile rubber, 0.1 to 20 parts by weight of a metal silicate and 0.1 to 10 parts by weight of a vulcanizing agent. Vulcanization of this vulcanizable rubber composition gives a vulcanizate exhibiting enhanced heating aging resistance when it is kept in a hot air atmosphere, especially at a high temperature.

Abstract: A rubber composition comprising a nitrile rubber and incorporated therein an organic sulfonic acid salt. A vulcanized rubber article obtained by vulcanization of the rubber composition exhibits a reduced deterioration in tensile strength and elongation when kept in a hot-temperature air atmosphere.

Abstract: A nitrile group-containing highly saturated copolymer rubber comprising (a) 0 to 20% by weight of 1,3-butadiene units, (b) 0 to 50% by weight of saturated 1,3-butadiene units, (c) 40 to 50% by weight of &agr;,&bgr;-ethylenically unsaturated nitrile monomer units, and (d) 10 to 35% by weight and at least 8% by mol of other monomer units, wherein the sum of 1,3-butadiene units (a) and saturated 1,3-butadiene units (b) is in the range of 20 to 50% by weight. A rubber composition comprising this copolymer rubber and a crosslinking agent gives a crosslinked product exhibiting good oil resistance, namely, good resistance to rancid gasoline and not hardening even when it is placed in contact with oil containing condensed aromatics.

Abstract: A vulcanizable rubber composition comprising 100 wt. parts of a highly saturated nitrile copolymer rubber having an iodine value not larger than 80, 3-30 wt. parts of a reinforcing filler, 30-200 wt. parts of an oxide of a metal of group 2 of the periodic table, 30-200 wt. parts of a non-reinforcing filler, and 0.1-20 wt. parts of a vulcanizer. A sealing material comprised of a vulcanizate of the vulcanizable rubber composition and having friction coefficient (.mu.) not larger than 1.5 and an abrasion wear of 150-350 mg. A seal comprising the sealing material and a reinforcing ring.

Abstract: A vulcanizable rubber composition comprising (1) a hydrogenated product of an unsaturated nitrile-conjugated diene-unsaturated carboxylic acid ester copolymer, (2) an ultrafine magnesium silicate powder having an average particle diameter of not larger than 10 .mu.m and (3) a vulcanizer. This rubber composition gives a vulcanizate having good resistance to hydrofluorocarbon gas transmission and good cold resistance, and is useful for a hose for hydrofluorohydrocarbon gas.
