摘要： A polar solvent solution of the present invention is a polar solvent solution in which a solute containing a polyamino acid is dissolved in a polar solvent. An inorganic salt is added to the solution, and a mole ratio of moisture to the inorganic salt in the solution is 2.5 × m × n or less, where m represents the number of cations forming the inorganic salt and n represents a charge number of the cation. A production method of the present invention is a method for producing the above solution, including: changing at least one of a moisture content and a content of the inorganic salt in the solution to adjust a viscosity of the solution. Thus, the present invention provides a polar solvent solution whose viscosity can be easily adjusted to a desired value and thus enables stable spinning and casting when used as dopes for spinning, film, etc., and methods for producing the same.

摘要： A polar solvent solution of the present invention is a polar solvent solution in which a solute containing a polyamino acid is dissolved in a polar solvent. The solution has a moisture content of less than 5 mass% based on 100 mass% of the solution. A method for producing a polar solvent solution of the present invention includes changing a moisture content of the solution to adjust the viscosity of the solution. Further, another method for producing a polar solvent solution includes reducing a moisture content of the solution to increase the viscosity of the solution. Thus, the present invention provides a polar solvent solution that enables stable spinning and casting without lowering its viscosity when used as dopes for spinning, film, etc., and methods for producing the same.

摘要： In an information processing apparatus, a display control part 31 causes a display part to display one or more human models in which parameters relating to shapes and sizes are set. A model selection reception part receives, from a user, a selection operation for selecting one human model from the one or more human models. A parameter changing part 34 changes the parameters set for the human model in conjunction with a change operation from the user for the selected human model.

摘要： A solution-dyed protein fiber of the present invention includes 0-100 mass% of silk fibroin and 100-0 mass% of a polypeptide derived from spider silk proteins when the protein fiber is assumed to be 100 mass%, wherein the solution-dyed protein fiber contains a solution-dyeing colorant. The fiber is obtained by: dissolving or dispersing a solution-dyeing colorant in a solvent used for a spinning solution or in dimethyl sulfoxide, thereby preparing a coloring liquid; adding a solvent to the coloring liquid in an amount necessary for a spinning solution; adding and dissolving protein powder into the solvent, thereby preparing a spinning solution; and subjecting the spinning solution to wet spinning or dry-wet spinning. Thereby, the present invention provides a low-cost solution-dyed protein fiber in which a solution-dyeing colorant is dispersed uniformly and that can exhibit bright color tone, and a method for producing the same.

摘要： A garment order reception management device 1 wherein a garment selection unit 301 receives a garment selection from a user. A price calculation unit 302 calculates a price for the garment on the basis of the type of the selected garment, and parameters related to the design and material that have been set for the garment. A display control unit 300 displays the calculated price on a display unit. A parameter changing unit 305 changes the parameters in association with inputs from the user. The display control unit 300 uses the change in the parameters as a trigger for displaying on the display unit a price that reflects the changed parameters.
