20090199950 | METHOD AND SYSTEM FOR LAMINATING OPTICAL ELEMENTS - [Objects] To make it possible to carry out automatically and accurately a laminating operation of an optical element to a sheet-shaped body. | 08-13-2009 |
20100167060 | METHOD OF JOINING SHEET MEMBER AND SHEET JOINED BODY - An object of the present invention is to provide a method of joining sheet members together that is capable of joining two sheet members together without causing a stepped portion on a joined portion. Provided is a method of joining a first sheet member and a second sheet member together, which includes bringing an end face of the first sheet member into abutment with an end face of the second sheet member to provide an abutted portion, heating the abutted portion via a heating medium to thermal-fusion-bond the end faces with each other, and peeling off the heating medium from the first and second sheet members after the thermal-fusion bonding. | 07-01-2010 |
20100215963 | METHOD OF PRODUCING SHEET JOINED BODY AND SHEET JOINED BODY - An object of the present invention is to provide a method of producing a sheet joined body that is unlikely to make a sheet joined body cause a stepped portion on at least one side thereof and is capable of providing an excellent joining strength to a sheet joined body. Provided is a method of producing a sheet joined body, which includes a covering step of bringing end faces of sheet members, which sheet members containing a thermoplastic resin, into abutment with each other to provide an abutted portion and covering one side of the abutted portion with a joining member, and a joining step of irradiating a portion covered with the joining member with laser light to fusion-bond the sheet members and the joining members together, thereby joining the sheet members together. | 08-26-2010 |
20100273313 | MANUFACTURING METHOD OF LASER PROCESSED PARTS, AND PRESSURE-SENSITIVE ADHESIVE SHEET FOR LASER PROCESSING USED FOR THE SAME - A manufacturing method of laser processed parts in which at least a pressure-sensitive adhesive layer is provided on a base material as a pressure-sensitive adhesive sheet for laser processing, using a material having specified physical properties. This method comprises adhering the pressure-sensitive adhesive sheet for laser processing to the laser beam exit side of the work by way of the pressure-sensitive adhesive layer, processing the work by irradiating the work with a laser beam of within 2 times of the irradiation intensity for forming a through-hole in the work, at higher than the irradiation intensity of threshold for inducing ablation of the work, and peeling the pressure-sensitive adhesive sheet for laser processing from the work after the machining. Therefore, contamination of the work surface by decomposition products can be effectively suppressed, and laser processed parts can be manufactured easily and at high production efficiency. | 10-28-2010 |
20100288441 | METHOD AND SYSTEM FOR LAMINATING OPTICAL ELEMENTS - [Objects] To make it possible to carry out automatically and accurately a laminating operation of an optical element to a sheet-shaped body. | 11-18-2010 |
20110297312 | METHOD OF PRODUCING SHEET JOINED BODY - A method of producing a sheet joined body includes: abutting ends of sheet members against each other, coating an abutted part with a joining member containing a thermoplastic resin, and irradiating a part coated with the joining member, with laser light to join the sheet members with the joining member by welding, thereby joining the ends with each other to manufacture a sheet joined body. | 12-08-2011 |
20130199732 | METHOD OF STRIPPING MULTIPLE PLIES OF A PRESSURE-SENSITIVE ADHESIVE LAYER, AND A PRESSURE-SENSITIVE ADHESIVE LAYER USED THEREIN - The present invention provides a method of stripping multiple plies of a pressure-sensitive adhesive layer, capable of easily separating and dismantling the joint portion in a short time, without affecting the adherend involved. The stripping method of the present invention strips the multiple plies of a pressure-sensitive adhesive layer, including a pressure-sensitive adhesive body having at least a pressure-sensitive adhesive layer containing heat-expandable fine particles and an adherend, the pressure-sensitive adhesive body and the adherend being laminated on each other, and the multiple plies of a pressure-sensitive adhesive layer contain a coloring matter component, and the pressure-sensitive adhesive body and the adherend are stripped from each other, by irradiating the coloring matter with a laser light beam having a wavelength coinciding with the absorption wavelength of the coloring matter and by expanding the heat-expandable fine particles with the aid of the heat thus generated. | 08-08-2013 |
20150218409 | METHOD FOR MANUFACTURING PHOTO-RESPONSIVE CROSS-LINKED LIQUID-CRYSTALLINE POLYMER FILM - The present invention relates to a method for manufacturing a photo-responsive cross-linked liquid-crystalline polymer film, containing: a process of preparing a photopolymerizable monomer solution by dissolving in a solvent a polyfunctional liquid-crystalline monomer, a monofunctional liquid-crystalline monomer, a polyfunctional photo-responsive monomer and a photopolymerization initiator; a process of forming a photopolymerizable coating by applying the photopolymerizable monomer solution to a surface of an alignment film by means of a wet coating method and performing removal of the solvent; and a process of forming a film by photopolymerizing the monomers through light irradiation of the photopolymerizable coating under a non-oxygen atmosphere. | 08-06-2015 |
