Patent number: 7665208Abstract: A first through hole is formed in a laminate by trepanning machining using laser light, for example. The trepanning machining refers to a process for irradiating laser light along such a trajectory that the laser light is first irradiated onto a substantially central area of a first through hole to be formed, the laser light is irradiated along a circumference corresponding to the bore diameter of the first through hole to be formed, and the laser light is finally irradiated onto the substantially central area of the first through hole to be formed again. A second through hole being substantially concentric with and having a larger bore diameter than the first through hole is formed by irradiating the laser light, similarly to the first through hole.Type: GrantFiled: June 21, 2007Date of Patent: February 23, 2010Assignee: Nitto Denko CorporationInventors: Kanji Nishida, Naoyuki Matsuo, Masakatsu Urairi

Publication number: 20090199950Abstract: [Objects] To make it possible to carry out automatically and accurately a laminating operation of an optical element to a sheet-shaped body. [Means for Accomplishing the Objects] A strip-shaped polarizing film has a protective film strip conformably adhered to one surface thereof and a releasable liner conformably adhered to the other surface thereof and delivered from a film delivering station 1. After an appearance inspection, a lamination of the protective film strip and the polarizing film strip F is half-cut using a laser unit 11 to form an array of laminations each consisting of a protective film and a polarizing film F, with the releasable liner being left intact. Then, the polarizing films F are fed to a peeling mechanism 4. The peeling mechanism 4 feeds a forwardmost one the polarizing films F to a laminating mechanism 5 while peeling off the releasable liner therefrom by a knife-edged member.Type: ApplicationFiled: April 13, 2009Publication date: August 13, 2009Applicant: NITTO DENKO CORPORATIONInventors: Kazuo KITADA, Yoshihiro KAMEDA, Kanji NISHIDA, Tomokazu YURA, Takaichi AMANO, Hiromichi OHASHI, Atsushi HINO, Naoyuki MATSUO
