A test paper includes a porous membrane capable of separating an object that should be filtered out of a sample by filtration, the porous membrane carrying a reagent capable of reacting with a specified component of the sample to result in coloring. Identification and verification data is stored during system enrollment of known persons. The LFM functions as part of an \u201ceffective\u201d exchange break layer that also includes the actual EBL and the AF-coupling layer, thereby allowing the actual EBL to be made as thin as possible. Since moldings obtained from this resin composition simultaneously satisfy both the good frictional wear characteristics and the high vibration damping performances, they can be suitably employed for the uses such as vibration-proof sliding components in the fields of precision machines, OA appliances and automobiles.
