  • Publication number: 20190240890
    Abstract: A process of producing a hollow resin-molded article includes: arranging covers on inner walls of mold halves, the covers having shapes corresponding to the inner walls; introducing a pair of sheets of thermoplastic resin each facing the cover arranged on the inner wall of a corresponding mold half; blowing air into a space between the sheets to cause the sheets to respectively contact the covers arranged on the inner walls, and thereby fusion-welding the sheets to the covers; and closing the mold halves; and cooling down the covers and the sheets in a state where the mold halves are closed. In the step of arranging, there are uncovered portions of the inner walls that are not covered by the cover. In the step of closing, there are mold contact portions of the sheets that respectively contact the uncovered portions directly and the mold contact portions are fusion-welded to each other in an overlapping manner.

  • Patent number: 9920390
    Abstract: There is proposed a method for preliminary treatment of molten iron wherein heat source for dissolving scrap is ensured sufficiently to improve iron yield while decreasing phosphorus concentration efficiently by suppressing the amount of flux solvent used in the process of desiliconization, dephosphorization and decarburization. In the method for preliminary treatment of molten iron by conducting desiliconization and dephosphorization of molten iron with a converter type container, molten iron is first charged into the converter type container to conduct desiliconization and then intermediate slag removal is conducted, and subsequently a lime-based flux solvent is added to the container while blowing oxygen to conduct dephosphorization of the molten iron, and thereafter newly untreated molten iron is charged into the container to conduct desiliconization, and subsequently the above treatments are repeatedly conducted with the same container.

  • Publication number: 20180048001
    Abstract: A hydrogen storage container has an inner side resin layer that comes into contact with hydrogen gas that is introduced into the container, a barrier layer which is disposed on the outside of the inner side resin layer and which prevents permeation of hydrogen gas, and an outer side resin layer comprising a resin. Among these layers, the inner side resin layer comprises a polyethylene-based resin, and if the thickness of the barrier layer is denoted by Y and the thickness of the inner side resin layer is denoted by X, the thickness X satisfies formula (1). Moreover, D in formula (1) is the diffusion coefficient of the polyethylene-based resin, as determined by means of a differential pressure method at 50° C.
