    摘要： A buried pipe laying method of additionally coupling a new pipe with the extreme end of a buried pipe laid underground involves flatly deforming a cylindrical pipe having a pipe length smaller than the inside diameter of the buried pipe, conveying the deformed cylindrical pipe to the extreme end of the buried pipe laid underground through the interior thereof, and then returning the deformed shape of the cylindrical pipe to its original circular shape and coupling it with the extreme end of the buried pipe.

    摘要： A removable pressure-sensitive adhesive which, even when applied to metal sheets or to metallic members which have undergone a coating treatment, is inhibited from increasing in adhesive force with the lapse of time and can be easily removed therefrom and which has satisfactory weatherability and satisfactory pot life contains 100 parts by weight on a solid basis of an aqueous dispersion type acrylic copolymer obtained by polymerizing a monomer mixture in an aqueous medium in the presence of a nonionic surfactant and/or an anionic surfactant each having an ethylenic double bond and 0.1 to 3 parts by weight of a hindered-amine light stabilizer having a piperidine ring in which the nitrogen atom has a tertiary amine structure; and an adhesive sheet is produced with the adhesive.
