Abstract: In a microneedle sheet having a microneedle array composed of a large number of microneedles Formed on the surface of the sheet, the ridge lines or conical plains of the microneedles are curved inward into said microneedles. Since the ridge lines or conical planes of the microneedles have a shape curved inward into the microneedles, a microneedle sheet that can be smoothly inserted into the skin can be provided.

Abstract: An emulsification apparatus is used in a production apparatus of microcapsules. The emulsification apparatus is constituted with an outer cylinder and an inner cylinder coaxially arranged in a superposed manner, the outer cylinder is fixed, and the inner cylinder is rotated at a circumferential speed ?. A liquid being processed is fed into the gap between the outer cylinder and the inner cylinder, thus a shear force is exerted to the liquid being processed, and the liquid being processed is thereby emulsified. The relation between the magnitude d (mm) of the gap, the viscosity ? (mPa·sec) of the liquid being processed and the circumferential speed ? (m/sec) of the inner cylinder is such that the circumferential speed co is controlled so that any one of the following relations may be satisfied: (1) When ??20, d?5/?; (2) When 20<??50, d?10/?; (3) When 50<??100, d?20/?; (4) When 100<?.

Abstract: In the method for manufacturing pattern members, a plurality of different kinds of materials are formed into the respective patterns on a web. In the method, a material transfer sheet on which a material layer for a pattern member has been formed is made in close proximity to the web and to run in such a direction as to intersect the direction of the web running, while allowing the web to run, and at the points where the web and the material transfer sheet intersect, the material layer for the pattern member is transferred from the material transfer sheet to the web with a transferring device so that it is formed into a pattern. Thus, both productivity and product quality are improved in the manufacturing of pattern members.

Abstract: The present invention provides a method of producing a pattern member at high productivity and low cost. In the method of the present invention, inks of plural colors are applied on a substrate and dried to produce several kinds of single color films having color ink layers of plural colors formed on the surface, then, the single color film of R color is overlapped on the substrate, and the overlapped substrate and single color film are pressed by a pressing member having a convex portion of given pattern formed on the surface, to transfer parts corresponding to the pattern of the convex portion of the color ink layer to the substrate. The above-described operation is repeated at frequency corresponding to plural colors to form a multi-color pattern composed of color ink layers of plural colors of given pattern on the substrate.

Abstract: Broad parts are formed on at least one passage including a passage for forming the thinnest layer among passages for respective resin layers of a multilayer sheet at an upstream side of a confluence. In the broad parts, clearances become larger to both ends of the passage along the width thereof.

Abstract: To stably coat a surface of a web with multiple coating liquids containing polyvinyl alcohol (PVA) to simultaneously form multiple layers on the surface of the web by means of a slide-hopper coating apparatus, a polymerization degree of PVA contained in one of the coating liquids forming the bottom layer among the multiple layers is within the range between 1000 and 4000, and a density of PVA contained in the coating liquid forming the bottom layer is at most 4% by weight, and a viscosity of at least one of the coating liquids that forms one of the layers other than the bottom layer is higher than a viscosity of the coating liquid forming the bottom layer. Alternatively, the polymerization degree of PVA contained in the coating liquid forming the bottom layer is within the range between 1000 and 4000, and an additive used to increase viscosity is added to the coating liquid forming the bottom layer within the range between 0.05% and 0.

Abstract: Polymer polysaccharide is added to a PVA coating liquid so that a density of the polymer polysaccharide is within the range between 0.05% and 0.5% by weight with respect to the PVA coating liquid. Next, a coating liquid layer is formed on a web by coating the web with the PVA coating liquid to which the polymer polysaccharide is added so that a temperature of the PVA coating liquid is within the range between 20° C. and 40° C. at the coating. Then, the coating liquid layer on the web is dried after it is preliminarily dried so that a temperature of the coating liquid layer is maintained at a temperature that is 3° C. lower than the temperature of the PVA coating liquid or lower for three seconds or more.

Abstract: A running web is coated with a coating liquid containing polyvinyl alcohol by means of a slide hopper that has a slide surface of which the inclining angle with respect to a horizontal plane is within a range between 5° and 30°; a thickness T [mm] of the coating liquid on the running web is smaller than a thickness S [mm] of the coating liquid flowing down along the slide surface; a bead clearance CL [mm] between the end of the slide surface and the running web at the bead part is determined in accordance with the thickness T [mm] of the coating liquid on the running web in an inequality, T+0.05<CL<2T+0.1; and a bead back pressure P [mmH2O] reduced at a bottom of the bead part with respect to an atmospheric pressure is determined in accordance with the bead clearance CL [mm] in an inequality, 2/CL+20<P<10/CL+20.

Abstract: An improved method for forming a multilayer sheet or multilayer film and an improved forming die apparatus, include making the thickness of the multilayer sheet or multilayer film uniform along the width. In the forming die apparatus, an elastic choke bar is disposed in a passage of the melted resin along the width of the passage. A plurality of bolt members are arranged to abut against the choke bar. The choke bar is pushed and pulled by each bolt member, and a part of the choke bar corresponding to the bolt member is bent with regard to the passage. Thereby, the clearance along the width of the passage can be adjusted for every bolt member.
