Patent number: 7811501Abstract: A mold which is processed by ion beam irradiation or electron beam irradiation and in which a throughput of the mold is high and a decrease in the throughput or electrostatic discharge due to charging does not occur, a method of producing the mold, and a method of producing a molded article produced using the mold. When molding a plastic resin, at least one of a cavity and a core is provided on the surface of a conductive glass substrate. A method of producing a mold for molding a plastic resin or the like includes forming at least one of a cavity and a core by irradiating an ion beam on the surface of a conductive vanadate glass substrate that contains vanadium pentoxide (V2O5) as a main component and that has an electric conductivity in the range of 1.0×10?1 to 1.0×10?8 S/cm.Type: GrantFiled: September 5, 2005Date of Patent: October 12, 2010Assignee: Kitakyushu Foundation for the Advancement of Industry, Science and TechnologyInventors: Tetsuaki Nishida, Ken-ichi Kobayashi, Akira Morishige

Publication number: 20100215432Abstract: The invention provides blocks made of certain material, equipped with drainage and ventilation functions, and a side of the blocks formed with first interlocking part and second interlocking part in the opposite but corresponding side while other two sides without the interlocking part formed with ventilating channels penetrating the center of the block unit and other areas without first and second interlocking parts equipped with chamfered channels in certain length and width. The blocks of the invention are paved in multi-layers and equipped with numerous ventilation channels and longitudinal grooving. Thus, the multi-layer structure provides sound drainage of water and moisture while preventing subsidence of road via maximizing the maintenance period of the pavement.Type: ApplicationFiled: May 15, 2007Publication date: August 26, 2010Inventors: Heung Sik Yu, Seong Kyun Jin
