Abstract: A coating comprising a urethane resin as a base, and at least polyurethane particles and fluororesin powder is formed on a surface of a member that is, or can be, contacted with an optical disk in an optical disk apparatus. The coating can prevent the optical disk, i.e., a CD, a DVD, etc., from damaging, even if the optical disk is contacted with a tray or an objective lens.

Abstract: A resin composition, for sliding member, which has a high degree of mechanical strength and wear resistance regardless of whether grease is applied to gears or the like formed thereof, attacks mating member formed of unflexible materials as well as flexible materials, is moldable, and can be molded into a product; and a gear formed thereof. The resin composition for sliding member comprises a resin; a solid lubricant; a whisker having Mohs hardness of five or more and a whisker having Mohs hardness of less than five.

Abstract: A heat-resistant, lubricative resin composition which can withstand temperatures of 250-270.degree. C., which is wear-resistant and low in friction, and which is less likely to attack a soft alloy such as aluminum alloy, and a high-performance, heat-resistant sliding bearing formed from the abovementioned heat-resistant, lubricative resin composition.

Abstract: Stripping fingers for use in a copying machine, molded of a liquid crystal polyester resin composition made up of a liquid crystal polyester having a flow temperature of 340.degree. C. or higher and titanium oxide whiskers. The stripping fingers have excellent heat deflection resistance, heat aging resistance, thermal shock resistance, heat load resistance, low attack on the counter roller, good shape retainability of the finger edges, and good non-stick property against toner. Coating with PFA at 330.degree. C. or higher on the stripping finger increases non-tackiness.
