Abstract: The light emitting device has a substrate, a light emitting element arranged on the top surface of the substrate, a frame body arranged on the top surface of the substrate so as to surround the light emitting element and reflecting light from the light emitting body, and a sealing material arranged inside the frame body and sealing the light emitting element, and the frame body has a first frame portion having a first inner circumferential curved surface protruding to the side of the light emitting element and a second frame portion having a second inner circumferential curved surface, and a connection portion of the first frame portion and the second frame portion is arranged so as to have the same height as that of the top surface of the light emitting element.

Abstract: A decanter centrifuge that carries out solid-liquid separation by centrifugal force on an object to be processed that is fed into a rotating bowl and designed from a solid and a saturated solution wherein that solid is dissolved, and discharges solid phase components from a solid discharge opening and discharges liquid phase components from a solvent discharge opening thereof by rotationally operating a screw conveyor disposed within the rotating bowl, the decanter centrifuge being provided with a dilution solvent supply unit for supplying, during centrifuging of the object to be processed, dilution solvent that reduces the concentration of the saturated solution to a discharge path, which is a discharge path for saturated solution moving within the rotating bowl, and which is designed closer to the solvent discharge opening side-than a chamber for supplying the object to be processed.
