Abstract: A light-emitting device includes: a package defining a recess; a light-emitting element disposed on a bottom surface of the recess; and a sealing member disposed in the recess so as to cover the light-emitting element. The sealing member includes a filler-containing layer which contains a filler and covers the light-emitting element, and a light-transmissive layer disposed on the filler-containing layer. The recess is further defined by a lateral surface having a stepped portion between the bottom surface of the recess and an opening of the recess. The light-transmissive layer covers the stepped portion. An upper surface of the light-transmissive layer is downwardly recessed.

Abstract: A light-emitting device includes: a package defining a recess; a light-emitting element mounted on surface that defines a bottom of the recess; and a sealing member disposed in the recess so as to cover the light-emitting element and made of a light-transmissive resin that contains a filler with an average particle diameter of 200 nm or more and 500 nm or less. The sealing member comprises a filler-containing layer, which contains the filler, and a light-transmissive layer that are layered in an order from a bottom side of the recess. The filler-containing layer has a thickness of equal to or larger than a height of the light-emitting element.

Abstract: A method for producing meal containing mannose, wherein powder particles containing cellulose and/or hemicellulose is mixed with the wet composition obtained by having a mannnan degrading enzyme function to Arecaceae plant-derived meals such as copra meal and/or palm kernel meal followed by the drying process. Production rate of mannose is increased by causing reaction under high level of water content, in addition to which drying efficiency is increased by mixing hygroscopic fiber materials to the wet composition, an enzymic reactant, and thus meal containing mannose can be produced with high efficiency and good economical performance.
