Abstract: A microporous soundproofing material constituted of an expanded material formed through the step of impregnating a thermoplastic elastomer with an inert gas at a high pressure and then decompressing the impregnated elastomer. The soundproofing material has a high characteristic impedance, is clean and lightweight, and has excellent flexibility. This microporous soundproofing material includes: a microporous soundproofing material which is constituted of an expanded material formed through the step of impregnating an unexpanded molding comprising a thermoplastic elastomer with an inert gas at a high pressure and then decompressing the impregnated molding; and a microporous soundproofing material which is constituted of an expanded material formed by impregnating a molten thermoplastic elastomer with an inert gas at a high pressure and then subjecting the impregnated elastomer to molding simultaneously with decompression.

Abstract: The present provides a condensed pyridine compound (I) represented by the following formula: 1

Abstract: The present provides a condensed pyridine compound (I) represented by the following formula: (wherein, R2 represents ring A represents benzene ring, pyridine ring, thiophene ring or furan ring; and B represents its pharmaceutically acceptable salt or hydrates thereof, which is a clinically useful medicament having a serotonin antagonism, in particular, that for treating, ameliorating or preventing spastic paralysis or central muscle relaxants for ameliorating myotonia.

Abstract: A damping material is made of a porous member having an absolute characteristic impedance value of not less than 800 kg/m2·S in the frequency range of from 1.0 to 3.0 kHz. A damping method has steps of providing a damping material in the interior or on the periphery of a vibration-generating apparatus, characterized in that as the damping material there is used a compressible porous member having an air permeability of from 1×{fraction (1/10)}10 to 2×{fraction (1/10)}2 cc/cm2/sec based on an atmospheric pressure difference of 2.039×{fraction (1/10)}4 mMH2O or a porous member having an absolute impedance value of not less than 800 kg/m2·S in a frequency range of from 1 to 3 kHz or one obtained by providing a film layer thereon. A disc drive has a motor for rotating a disc as a data recording medium and a damping material provided in the interior and/or on the periphery of a housing having at least a space in which the disc can be mounted.
