摘要:
The present invention relates to a sustained-release pharmaceutical composition comprising a hydroxyalkanoic acid copolymer consisting of a 3-hydroxybutyric acid unit and a 4-hydroxybutyric acid unit, and a biologically active substance. The sustained-release pharmaceutical composition of the present invention can regulate the degree of release of a biologically active agent easily by changing the ratio of the 3-hydroxybutyric acid (3HB) component to the 4-hydroxybutyric acid (4HB) component in P(3HB-co-4HB) as a basic substance and by changing the thickness of its sheet.
摘要:
Materials not releasing gaseous organic materials during use are used as a dry-type sealing material such as a gasket disposed upon mounting an air filter to an opening of a ceiling or the like, a wet-type sealing material filled and used in a gap for connecting wall materials or partitionings, a vinyl chloride sheet or a vinyl chloride cloth as a facing material for walls and floors. Specifically, a carboxylic acid ester having a molecular weight of not less than 400 is used as a plasticizer, a phenolic compound having a molecular weight of not less 300 is used as an antioxidant, an aliphatic hydrocarbon having not less than 19 carbon atoms (for example, microcrystalline wax) is used as a lubricant, and an alkylamine ethylene oxide adduct having a molecular weight of not less than 350 is used as an antistatic agent.

摘要:
A process for separation of an asbestos-containing material from a surface to which the asbestos-containing material is adhered and for prevention of floating of dust of the asbestos-containing material in the air, comprising jetting pressurized water from a plurality of nozzles to the surface at a pressure of at least 80 kg/cm²·G so as to remove the asbestos-containing material by the energy possessed by the pressurized water.
摘要:
A concrete structural member of improved stability is produced by preparing a concrete composite layer 5 having a concrete layer 2 on one side and an aggregate layer 4 on the other side thereof, impregnating the composite layer 5 with a monomer, thermal-catalytic treatment the monomer-impregnated composite layer 5 thereby polymerizing the monomer embedded in the composite layer 5, and thereafter placing fresh concrete 7 on the aggregate layer 4' side of the polymer-impregnated composite layer 6.
