20080221532 | MICRONEEDLE SHEET AND METHOD FOR MANUFACTURING THE SAME - 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. | 09-11-2008 |
20090294998 | Method and Apparatus for Producing Embossed Sheet - A method of producing an embossed sheet includes the steps of allowing a flexible strip-shaped sheet to continuously travel, forming a coating layer by coating the surface of the sheet with a radiation curable resin, transferring a pattern of concavities and convexities on the surface of the emboss roller to the coating layer by winding the sheet around the rotating emboss roller, curing the coating layer by irradiating the sheet which is wound around the roller with radiation, releasing the sheet from the emboss roller, laminating a protective film on one or both sides of the continuously traveling sheet after releasing, and taking up the continuously traveling sheet after lamination in the form of a roll. According to the method, a high quality, defect-free embossed sheet having a fine regular pattern of concavities and convexities on the surface can be produced at high line speed with high productivity. | 12-03-2009 |
20100028554 | METHOD FOR MANUFACTURING EMBOSSED SHEET AND APPARATUS THEREFORE, METHOD FOR MANUFACTURING PATTERNED SHEET, AND PATTERNED SHEET - An embossed sheet, on which fine embossed patterns are regularly formed on a surface, is manufactured without any defects and with a high quality at a high line speed and at a high level of productivity. A method for manufacturing an embossed sheet, in which irregularities of a surface of an emboss roller is formed by transfer on a surface of a flexible strip-shaped sheet W. After coating a resin solution which is diluted with an organic solvent, the sheet on which a resin solution layer is formed on a surface is continuously run, the organic solvent contained in this resin solution layer is dried, the sheet after dried is wound around the emboss roller which is rotating, and irregularities of a surface of the emboss roller are transferred to the resin solution layer, and then the resin solution layer is cured, with the sheet being wound around the emboss roller. | 02-04-2010 |
