Abstract: A mixed gas separation method includes a step of supplying a mixed gas to the separation membrane and causing a gas with high permeability in the mixed gas to permeate through the separation membrane. In the step, when ?P is a difference between a gas pressure on the primary side of the separation membrane, i.e., a feed pressure, and a gas pressure on the secondary side of the separation membrane, i.e., a permeate pressure, and A is a Joule-Thomson coefficient, a difference ?T between a gas temperature on the primary side of the separation membrane, i.e., a feed temperature, and a gas temperature on the secondary side of the separation membrane, i.e., a permeate temperature, is made less than 90% of A·?P by setting the Nu number in the mixed gas to be greater than or equal to 2 and less than or equal to 10.

Abstract: Provided is a vinylidene fluoride copolymer particle which is capable of efficiently exhibiting high adhesion between an electrode and a separator. The vinylidene fluoride copolymer particle of the present invention comprises vinylidene fluoride; and a compound having an oxygen atom-containing functional group; wherein a ratio of oxygen atom in a surface of the vinylidene fluoride copolymer particle is higher than a ratio of oxygen atom in the vinylidene fluoride copolymer particle other than the surface thereof.

Abstract: There are provided a coating composition for applying inkjet printing thereto to form a marked preparation, the composition providing good ink affinity, suppression of ink bleed, and excellent gloss; and others. More specifically, there are provided a composition for applying inkjet printing thereto to form a marked preparation, the composition including a water-soluble cellulose ether having a viscosity at 20° C. of from 2 to 50.0 mPa·s, as determined in 2% by mass aqueous solution, polyvinyl alcohol, and a solvent, wherein a mass ratio of the water-soluble cellulose ether to the polyvinyl alcohol is from 99.0:1.0 to 55.0:45.0; a method for producing a preparation marked with aqueous ink, including a coating step of coating an object with the composition to form a coating layer, and a printing step of inkjet-printing on the coating layer with aqueous ink to obtain a preparation marked with aqueous ink; and others.

Abstract: Provided is an Achilles tendon support capable of suppressing a dorsiflexion of an ankle joint as well as suppressing a twist of the ankle joint. The Achilles tendon support includes: an inner support section for covering an Achilles tendon and both side edge portions thereof, upper portions of the inner support section being fastenable to each other on a front side of an upper ankle portion with a hook and loop fastener; and an outer support section for covering the Achilles tendon and both the side edge portions thereof in a range from a sole through a back heel portion, upper portions of the outer support section being fastenable to an outer surface of the inner support section with a hook and loop fastener.
