Abstract: To provide a liquid medical material maintaining a colloid in a more sol form than a solid at normal temperature, having a higher function as a wound dressing material and a hemostatic material than fibrin glue, and being able to be produced safely and inexpensively. A gelatin aqueous solution including calcium at a concentration of 0.2 M or more and 1.0 M or less, and having a concentration of 5% by weight or more and 40% by weight or less, an average molecular weight of 80,000 or more and 120,000 or less, and a molecular weight distribution of 20,000 or more and 300,000 or less, and transglutaminase inducing crosslinking of the gelatin, are included. It is preferable that the calcium has a concentration of 0.2 M or more and 0.7 M or less, the gelatin has a bloom of 160 or more and 250 or less, and the transglutaminase has activity per unit of 36 U/ml to 400 U/ml.

Abstract: A release liner which makes it difficult for an adhesive layer to impair slidability and makes it easy to exhibit an adhesive force suitably, a method of producing a release liner, an adhesive sheet, and a method of producing an adhesive sheet. A release liner has a surface provided with a ridge portion extending linearly, and on the surface, a plurality of recesses having different depths are randomly formed in a surface direction and are continuously connected.

Abstract: An eyepiece structure for a surgical microscope includes an inner barrel, an intermediate barrel, and outer barrels. When the outer barrels are rotated, a protrusion of the inner barrel is guided along a spiral groove of the outer barrel and is moved back and forth along an optical axis. The protrusion is guided through a straight hole of the intermediate barrel that is not rotatable, and therefore, the inner barrel moves along the optical axis without rotating around the optical axis. An astigmatic lens is added to the inner barrel that is nonrotatable, to enable a surgeon suffering from astigmatism to conduct a surgical operation without glasses.

Abstract: Provided is a flame retardant adhesive sheet having an adhesive agent layer on at least one surface of a base material, which even when the adhesive agent layer does not contain a flame retardant agent, has both excellent flame retardant properties and adhesive properties. The present invention is concerned with a flame retardant adhesive sheet including an adhesive agent layer on at least one surface of abase material, wherein the base material has flame retardant properties adapted to VTM-0 in a test according to the UL94 standard; a thickness per surface of the adhesive agent layer is 0.6 ?m or more, and a total thickness of the adhesive agent layer is not more than 2.2 ?m; the adhesive agent constituting the adhesive agent layer does not contain a flame retardant agent but contains (A) an acrylic copolymer and (B) a specified urethane resin.

Abstract: A screw conveyor type drying apparatus has a plurality of hollow drive shafts each having a plurality of hollow feed vanes located on the respective drive shaft along an imaginary helix positioned on the outer peripheral surface of the drive shaft. The drive shafts are driven so that adjacent drive shafts are rotated in mutually opposite directions, whereby a material to be dried is conveyed. A heating fluid supply device feeds heating fluid into the hollow internal of the feed vanes through the hollow drive shafts, whereby the material coming in contact with the feed vanes during conveyance is heated and dried.
