Abstract:
PROBLEM TO BE SOLVED: To provide an edgelighting system planar light-emitting device enabling a light guide plate to emit bright light from both sides as well as the light guide plate used for the same.SOLUTION: For the edgelighting system light guide plate provided with a light-scattering layer at least on one of the sides of a translucent substrate, the light-scattering layer includes hollow particles with a primary particle size of 300 nm or less, a wall thickness of 30 nm or less, and a void ratio of 40% or more. Light incident from an end face of the substrate is reflected at the light-scattering layer to be emitted from the other face of the substrate, and at the same time, it also transmits the light-scattering layer to be emitted from that one side of the substrate.

PROBLEM TO BE SOLVED: To provide a method for separating and recovering an objective substance (for example, a rare earth element etc.) from a product etc. (for example, a rare earth magnet etc.) including the objective substance with low energy and at a low cost, and to provide a separation and recovery system for performing the method.SOLUTION: The method for separating and recovering an objective substance from a solid-state material RM containing at least one objective substance and another substance is provided, which includes: a heating step of heating the solid-state material into a material in a solid-liquid coexisting state by heating one surface side of the solid-state material using a heating means 22 under a low-oxygen atmosphere; and a recovery step of recovering the objective substance precipitated on the one surface side of the solidified material obtained when the material in a solid-liquid coexisting state is solidified after the heating step. The precipitated oxide is halogenated in a halogenation treatment part 3, further dehalogenated in a dehalogenation treatment part 6, and recovered. The heating step includes a collection step of collecting the objective substance evaporated from the solid-state material RM in a solid state using a collection plate 23.

PROBLEM TO BE SOLVED: To provide a production technology producible of fatty acid alkyl esters at high efficiency from oils and fats, and reducible of byproducts to be non-valuable in the production processes of fatty acid alkyl esters. SOLUTION: This method for producing fatty acid alkyl esters from oils and fats containing at least a fatty acid glyceride comprises at least: a first process of making the oils and fats and water coexist and reacting them at a temperature of 100-370°C and pressure of 1.0-100 MPa to convert the fatty acid glyceride into a fatty acid; and after the first process, a second process of adding a dialkyl carbonate and reacting them at a temperature of 240-400°C and pressure of 2.0-100 MPa to convert the fatty acid contained in the oils and fats after going through the first process into the fatty acid alkyl ester.

Abstract:
PROBLEM TO BE SOLVED: To provide surface-reformed porous silica which drastically reduces dielectric constant when it is dispersed into a polymer resin, and to provide a method for producing the same. SOLUTION: The method for producing the surface-reformed porous silica includes: a first surface treatment process in which pretreated porous silica, wherein, while leaving a part or all of silanol groups in pores, silanol groups other than a portion or all of silanol groups left in the pores are chemically modified with a first surface treating agent, is obtained by treating porous silica with the first surface treating agent; and a second surface treatment process in which the silanol groups remaining in the pores are chemically modified with a second surface treating agent by treating the pretreated porous silica with the second surface treating agent.

Abstract:
PROBLEM TO BE SOLVED: To reduce running cost of the conventional air compressor system by low capital investment, achieving energy saving to effectively utilize limited resources, and further reducing the amount of carbon dioxide emissions to lessen influence upon global warming. SOLUTION: A water-cooled heat pump for generating cold water and hot water at the same time is installed, the cold water is used as a heat sink of an air handling unit to cool a machine room, thereby improving the efficiency of the air compressor, and also used as a heat sink of a compressed air cooling and dehumidifying tower, and further hot water is used as a heat source of a compressed air heating tower.

Abstract:
PROBLEM TO BE SOLVED: To provide an evaluation method of a photocatalyst capacity, capable of accurately evaluating a visible-light reacting type photocatalyst product. SOLUTION: After the visible-light reacting-type photocatalyst product 1 is colored by a reagent containing azo dye, the photocatalyst product 1 is irradiated with a visible light, to measure the change in the color of the reagent, and the color change of the reagent is used as an index for measuring and evaluating the photocatalyst capacity. Since the evaluation reagent 4 for the photocatalyst capacity contains the azo dye and the reagent containing the azo dye is very difficult to be decomposed by visible light, the visible light reacting-type photocatalyst product 1 can be evaluated properly.
