Abstract: The purpose of the present invention is to train a learning model and thereby create a utility model, and assist with an operation for making practical use thereof. Provided is a computer system 50 for preparing learning models in one or more learning units 102; receiving an input of learning data from a data source 111, and training said one or more learning models using the learning data. One or more utility models are finalized on the basis of said one or more trained learning models, and said one or more utility models are deployed to one or more inference units 114. Each of said one or more inference units 114: receives an input of utility data from the data source 111; provides the utility data to the utility models and executes an inference; and transmits, to a data target 113, inference result data outputted from the utility models.

Abstract: A tungsten hexafluoride manufacturing method of the present invention includes a reaction step of reacting tungsten containing arsenic or an arsenic compound with a gas of a fluorine element-containing compound so as to obtain a mixture containing tungsten hexafluoride and a trivalent arsenic compound, and a distillation step of distilling and purifying the mixture so as to separate and remove a fraction containing the trivalent arsenic compound and to obtain tungsten hexafluoride.

Abstract: An acrylic adhesive tape exhibiting good adhesion to a curved surface and good peel characteristics under a constant load even in the absence of a cross-linking agent includes an acrylic adhesive layer photo-polymerized by irradiation with ultraviolet rays. The acrylic adhesive layer contains: an acrylic polymer A formed by irradiating a solvent-free photo-polymerizable monomer composition containing an acrylic monomer and a photopolymerization initiator with ultraviolet rays so that the acrylic polymer A is formed by photopolymerization of the acrylic monomer and has a weight average molecular weight of 700,000 to 3,000,000 when a cross-linking agent is absent; an acrylic polymer B having a weight average molecular weight of 350,000 to 650,000; and an adhesion-imparting polymer having a weight average molecular weight of 2,000 to 10,000. The acrylic adhesive layer has a molecular weight distribution of 2.4 to 4.4.

Abstract: In a double-sided adhesive tape in which acrylic-based adhesive layers are formed on respective sides of an electron beam cross-linked polyethylene foam substrate, the acrylic-based adhesive layers are formed from a cured resin composition formed by irradiating a solvent-free photopolymerizable monomer composition containing an acrylic-based monomer and a photopolymerization initiator with ultraviolet rays to photo-polymerize the acrylic-based monomer. The cured resin composition contains an adhesion-imparting polymer having a weight average molecular weight of 2,000 to 10,000, an acrylic-based polymer A obtained by photopolymerization in the absence of a cross-linking agent and having a weight average molecular weight of 700,000 to 3,000,000, and an acrylic-based polymer B obtained by photopolymerization in the absence of a cross-linking agent and having a weight average molecular weight of 350,000 to 650,000.

Abstract: The present invention provides yarn winder that can provide a vibration suppressing function for the yarn winder over a long period despite minor differences in vibration characteristic among individual yarn winders. A vibration suppressing device is provided in a yarn winder comprising rotatable bobbin holders 105 and 106 supported on a body frame 102, the bobbin holders each having bobbins installed thereon and around which packages P are formed. The vibration suppressing device comprises an impact damper 10 comprising a mass body 11 and a regulation member 13 for holding the mass body 11 in such a manner as to have degrees of freedom. The impact damper 10 is provided in a site that vibrates as the bobbin holders 105 and 106 rotate, for example, at a tip of an elevating bracket 109.
