The active ingredient used in the present invention is an intrinsic and safe substance, and so does not exhibit hypercalcemia which is the side effect induced by conventional antirachitic agents, and is effective for the treatment of rickets, particularly vitamin D resistant rickets.
摘要:
A method of manufacturing a vinylidene fluoride polymer wherein a vinylidene fluoride monomer and 1 to 5 wt.%, with respect to the total weight of the monomers, of hexafluoropropylene and/or tetrafluoroethylene comonomers are suspension-polymerized in an aqueous medium in the presence of an oil-soluble polymerization initiator, wherein: the logarithmic viscosity [η₁] of the polymer is from 1.3 to 1.9 dl/g from the start of the polymerization until the polymerization conversion rate of the vinylidene fluoride monomer is from 10 to 50%; and when the polymerization conversion rate is from 10 to 50%, a chain transfer agent is added to the polymerization system such that the logarithmic viscosity [η₂] of the polymer finally obtained is from 0.9 to 1.3 dl/g and also from 0.3 to 0.7 dl/g lower than [η₁].
摘要:
A process of producing a high-pure acyclic or cyclic chloroacetal with a good yield by a simple step of reacting a monochloroacetaldehyde trimer or a monochloacetaldehyde monomer obtained by heating the trimer in the existence of an acid catalyst and a monohydric or dihydric alcohol having from 1 to 5 carbon atoms in the existence of an acid catalyst or a dehydrating agent.
摘要:
A detection method of a liquid level (11) supplies fluid between a moving cylindrical body (26) such as a parison in a film manufacturing process and an ultrasonic transmitter (9) and receiver (10) or an ultrasonic transmitter-receiver opposite to an outer surface of the cylindrical body to keep acoustic contact between an ultrasonic vibration member and the cylindrical body through the fluid. A level of liquid in the cylindrical body is measured on the basis of whether ultrasonic propagating in the fluid and the liquid in the cylindrical body can be received with a predetermined signal level or not. Since the ultrasonic vibration member is brought into contact with the cylindrical body through the fluid, the contact state therebetween is kept good, and wear, flaw, deformation, frictional heat or the like is not given to the cylindrical body. Further, even if the surface of the cylindrical body is rugged, good contact can be kept. Preferably the fluid is flowing water.
摘要:
A modified polyphenylene sulfide resin is produced by the steps of mixing a polyphenylene sulfide resin with at least one silane compound selected from the group consisting of vinylalkoxysilanes, epoxyalkoxysilanes, aminoalkoxysilanes and mercaptoalkoxysilanes and kneading the mixture at a temperature which is higher by 5 to 100°c than the melting point of the polyphenylene sulfide resin for at least 30 seconds. It has an increased melt viscosity.
摘要:
A dispensing carton (1) containing film (8) wound cylindrically includes an adhesive retaining device (10) which retains the leading edge of the film (8) left after the film (8) pulled out from a carton box has been cut by a cutter (7). The retaining device (10) includes a base member (12), a sticking layer (11) mounted on one surface of the base member (12) to fix the base member (12) on the surface of the front panel (6) and an adhesive layer (13) mounted on the other surface of the base member (12). The adhesive layer (13) is formed of grafted copolymer obtained by graft-polymerizing vinyl chloride monomer with copolymer of ethylene and vinylacetate. Preferably, the adhesive layer (13) is formed of grafted copolymer obtained by graft-polymerizing vinyl chloride monomer having weight ratio of 80-20 with copolymer of ethylene and vinylacetate having weight ratio of 20-80 in which the weight ratio of ethylene and vinylacetate is 20-70 to 80-30. Further, the surface of the adhesive layer (13) is partially covered by a resin layer to reduce the surface area of the adhesive layer (14a, 14b) for retaining the film (8).
摘要:
A method for preparing a monochloroacetaldehyde trimer in a high yield is here disclosed which comprises the steps of dissolving, in an organic solvent, a solution containing monochloroacetaldehyde as the main component, and then trimerizing monochloroacetaldehyde in the presence of sulfuric acid. The thus prepared monochloroacetaldehyde trimer can be heated at 120°C under atmosphetic pressure to obtain pure monochloroacetaldehyde.
