    摘要： A loop portion of a bus wire connected to an electric blasting device is passed through a first magnetic core together with a first loop-like wire, and the first loop-like wire is further passed through a second magnetic core provided in a detonator. The detonator includes a second loop-like wire which is passed through the second magnetic core, an electric bridge connected to the second loop-like wire and a fuse head provided around the electric bridge. When a pulsatory high frequency current is supplied to the bus wire, high frequency currents are induced in the first and second loop-like wires by electromagnetic induction. Then the current flows through the electric bridge of the detonator to fire the primer explosive.

    摘要： A method for finish coating on polyurethane formed articles, which comprises formulating a finish coating composition so as to have a content of pyrrolidone or its derivative represented by the general formula ##STR1## in which R stands for hydrogen or an alkyl group having at the most 4 carbon atoms, in an amount of 5-40% by weight upon the coating, applying this finish coating composition on the polyurethane formed article directly and heating the so called polyurethane formed article at a temperature of at least 50.degree. C. but lower than the thermal deformation temperature of the polyurethane formed article, said method being capable of attaining a coating layer exhibiting both the properties for a primer coat, namely, a better adhesion onto polyurethane formed articles, and for a finish coat, namely, better weather resistance, higher chemical resistance, favorable appearance and so on, with only a single application and permitting thus to dispense with the primer coating and the heat drying procedure therefor.

    摘要： An unsaturated polyester resin composition comprising an unsaturated polyester resin, a polymerizable monomer and a mixture of block copolymers having acid groups prepared by first copolymerizing in a first copolymerization reaction a polymeric peroxide with a monomer A or B, or with an unsaturated acid together with monomer A or B, thereby obtaining a copolymer having peroxy bonds in the molecule thereof, which copolymer is further copolymerized in the second copolymerization reaction with each of monomers A or B or the unsaturated acid which were excluded in the first copolymerization reaction to give the block copolymer mixture, which composition shows no segregation of the low shrinkage agent on thickening by a thickener and the said composition gives cured moldings of reduced shrinkage which are excellent in many characteristics.Monomer A: a vinyl acetate or a mixture of vinyl acetate and one or more monomers which are copolymerizable with vinyl acetateMonomer B: styrene series monomers, unsaturated organic acids, anhydrides, or acid esters, or mixtures thereof
