    摘要: An information delivery system includes terminals receiving data via a satellite-communication system, and a user center having a destination-conversion table which lists a satellite-system receiver ID with respect to each ground-network address of the terminals, and, upon receiving a request for data delivery via an intra-network, obtaining satellite-system receiver IDs from ground-network addresses indicated as destinations of the data delivery by referring to the destination-conversion table so as to deliver requested data and a reception-control program to the destinations via the satellite-communication system. The terminals use the reception-control program to check the data-reception conditions when receiving the requested data and the reception-control program, and send a request for a repeat of the data delivery to the user center via the intra-network if the data-reception conditions are not satisfactory.

    摘要: A gas-barrier multilayered structure comprising (A) at least one layer of a copolyamide composed of (a) a dicarboxylic acid component composed of 55 to 70 mole % of an aliphatic dicarboxylic acid component and 45 to 30 mole % of an aromatic dicarboxylic acid component consisting substantially of 20 to 30 mole % of isophthalic acid and 5 to 20 mole % of terephthalic acid, and (b) a diamine component composed substantially of a m-xylylenediamine component, and (B) at least one layer of a thermoplastic resin other than the copolyamide. Instead of the layer (A), there can be used (A') at least one layer of a mixture of 40 to 60 % by weight of a first copolyamide composed of (a) a dicarboxylic acid component composed of 55 to 70 mole % of an aliphatic dicarboxylic acid component and 45 to 30 mole % of an aromatic dicarboxylic acid component consisting substantially of 20 to 30 mole % of isophthalic acid and 5 to 20 mole % of terephthalic acid and (b) a diamine component composed substantially of m-xylylenediamine and 60 to 40 % by weight of a second polyamide composed of a dicarboxylic acid component consisting substantially of an aliphthalic dicarboxylic acid component and a diamine component consisting substantially of a m-xylylenediamine component.
