Publication number: 20130328224Abstract: A resin amount for forming each first-stage resin layer portion (a first-stage resin replica portion) 41da in a first process is defined to be greater than a resin amount for forming each second-stage resin layer portion (a second-stage resin replica portion) 41db in a second process. Therefore, at a boundary between the first-stage resin layer portion 41da and the second-stage resin layer portion 41db, a joint portion 48 at which resin overlaps is formed, whereby occurrence of an undercut shape can be avoided. Therefore, in a molding process using a sub-master die 40 and a sub-sub-master die 50 obtained from the sub-master die 40, occurrence of an undesired shape can be avoided, whereby mold release resistance can be reduced or eliminated.Type: ApplicationFiled: March 5, 2012Publication date: December 12, 2013Applicant: KONICA MINOLTA, INC.Inventors: Katsuki Furuta, Hiroyuki Matsuda

Publication number: 20120248638Abstract: The material of core supporting members (12, 22) is selected such that the thermal expansion coefficient thereof is higher than that of molding sleeves (10, 20). Even when the diameter of openings (10a, 20a) of the molding sleeves (10, 20) is increased due to thermal expansion during transfer molding, the outside diameter of the core supporting members (12, 22) is further increased, gaps between the core supporting members (12, 22) and the openings (10a, 20a) are eliminated. As a result, the optical axes of transfer-molded surfaces formed on cores (13, 23) are accurately positioned with respect to the axes of the openings (10a, 20a), resulting in high-precision optical elements and the like.Type: ApplicationFiled: December 6, 2010Publication date: October 4, 2012Inventor: Hiroyuki Matsuda

Patent number: 8114190Abstract: Method and system for a cement burning facility. When exhaust gas in a part of a preheater or a kiln inlet of a cement kiln is extracted, a cement material is dispersed. The dispersed amount of the cement material is adjusted to maintain the temperature of the extracted gas between 950° C. and 1,150° C. The extracted gas is cooled to at most the melting point of a chlorine compound. A solid-gas separation device adjusts classification particle size to between 15 ?m and 30 ?m. A dust trap removes fine powder dust with a particle size equal to or smaller than the classification particle size. The amount of fine powder dust collected by the dust trap is maintained between 50 g/m3N and 150 g/m3N, with the concentration of chlorine in the collected fine powder dust set to between 5% and 20%.Type: GrantFiled: September 22, 2009Date of Patent: February 14, 2012Assignee: Mitsubishi Materials CorporationInventors: Yoshiaki Komatsu, Michio Ishizaki, Hirokazu Shima, Hiroyuki Matsuda
