  • Publication number: 20230347417
    Abstract: A build region limitation unit for an additive manufacturing apparatus includes a movable unit fixed to a build table and a non-movable unit placed on a base frame. The movable unit includes a first anti-scattering frame provided to protrude upward. The non-movable unit includes a flat plate that covers a first build region with a portion other than an opening and forms a second build region, and a second anti-scattering frame that is provided to protrude downward at an outer periphery of the opening. The first anti-scattering frame surrounds the second anti-scattering frame with a gap therebetween.

  • Patent number: 10987737
    Abstract: Provided is a laminate molding apparatus including a chamber, a laser irradiation device, an inert gas supply device, a fume collector, and an evacuate device. The evacuate device includes an intake port, an evacuate amount adjusting portion, a controller, and an evacuate port. The intake port is connected to any part of the laminate molding apparatus through which the inert gas flows, and takes in the inert gas. The evacuate amount adjusting portion adjusts an evacuate amount of the inert gas. The controller controls the evacuate amount adjusting portion to evacuate the inert gas such that an atmospheric pressure in the chamber and an external atmospheric pressure become uniform within a range in which leakage of the inert gas from the chamber is suppressed. The evacuate port evacuates the inert gas from which fumes have been removed to the outside of the laminate molding apparatus.

  • Patent number: 6942906
    Abstract: A resin sheet containing dispersed particles which is thin and lightweight, and has excellent mechanical strength and light-diffusing properties. The resin sheets may be used in liquid crystal displays. A resin sheet having a hard coat layer, an epoxy resin layer containing 100 parts by weight of the resin to 200 parts by weight of a diffuser having a refractive index different from that of the epoxy resin and having an average particle diameter from 0.2 to 100 ?m, and a thin metal layer as a reflecting layer, wherein the diffuser localizes so as to have a concentration distribution in the direction of the thickness of the epoxy resin layer. A resin sheet having dispersed particles which is obtained by superposing a reflecting layer, an inorganic gas barrier layer, or a color filter layer thereon. A process for producing the resin sheet having a color filter layer.

  • Patent number: 6818263
    Abstract: A resin sheet which comprises a base layer containing particles dispersed therein and hence has excellent dimensional stability; a resin sheet which comprises a base layer containing particles dispersed therein and hence has excellent light diffusion properties; resin sheets which comprise either of those resin sheets containing dispersed particles and a reflecting layer, inorganic gas barrier layer, and color filter layer respectively superposed thereon; and a liquid crystal display using any of these resin sheets containing dispersed particles. Some of the resin sheets containing dispersed particles comprise a base layer comprising a thermoplastic resin or thermoset resin and dispersed therein an inorganic oxide having an average particle diameter of 1 to 100 nm, the amount of the inorganic oxide being 0.1 to 23% by weight based on the weight of the base layer.

  • Publication number: 20040121087
    Abstract: A resin sheet which has abase layer containing particles dispersed therein, is thin and lightweight, and has excellent mechanical strength and light-diffusing properties; a resin sheet containing dispersed particles which is obtained by superposing a reflecting layer or an inorganic gas barrier layer on that resin sheet; a resin sheet containing dispersed particles which is obtained by superposing a color filter layer on that resin sheet; processes for producing the resin sheet having a color filer layer; and liquid crystal displays employing those resin sheets. One of those resin sheets has a hard coat layer, an epoxy resin layer containing, per 100 parts by weight of the resin, up to 200 parts by weight of a diffuser having a refractive index different from that of the epoxy resin and having an average particle diameter of from 0.
