A light-emitting body comprising a primary luminescent unit and a secondary luminescent unit that emits light owing to light emitted from the primary luminescent unit, wherein the secondary luminescent unit contains an iridium compound. As the iridium compound, an iridium complex represented by L1L2L3Ir, (L1, L2 and L3 are organic bidentate ligands coordinated to iridium, and at least one of these ligands coordinates with a nitrogen atom and a carbon atom) preferably, represented by formula (2) can be cited. (In the formula, X represents an atom group that forms an aromatic chelate ligand together with a carbon atom and a nitrogen atom bonded with iridium, n is an integer of 2 or 3, and L represents a bidentate organic ligand wherein the atoms other than carbon atoms are bonded with iridium.) The light-emitting body of the invention contains red (R), green (G) and blue (B) wavelength components to be wide in the color reproduction range, can be driven with a single power supply and control system, and does not cause photo-deterioration of constituent members.

摘要:
Micro-bubble generators attached to a ship hull below the waterline decrease frictional resistance during navigation and improve fuel efficiency. Each micro-bubble generator is supplied with air and has a wing positioned outside the hull for generating negative pressure. The negative pressure created by the wing increases with an increase in ship's speed, which pushes the air-liquid interface outwardly toward the wing. As the air and the water move at different speeds due to difference in their densities, micro-bubbles are generated in the micro-bubble generator according to the Kelvin-Helmholtz Instability mechanism and discharged downstream to move closely along the outside surface of the hull.

[Object] The present invention provides for a frictional resistance reduction ship able to decrease friction resistance and improve fuel efficiency.[Solution] When the navigation speed increases, and negative pressure which is created by the wing 33 increases, a result is that the air-liquid interface is pushed down further. Due to the air and the water (sea water) moving different speeds, density differs between air and water (as shown in FIG. 7), micro-bubbles are generated in the micro-bubble generator according to the Kelvin-Helmholtz Instability mechanism, and these micro-bubbles flow through onto the downstream side along the hull.
摘要:
In a backlight which arranges light emitting diodes on a side surface of a light guide plate, even when the light emitting diodes having a thickness larger than a thickness of the light guide plate are used, it is possible to manufacture the light guide plate with high accuracy by injection molding. In a liquid crystal display device having a backlight which radiates light to a liquid crystal panel, LEDs are mounted on the light guide plate formed on the backlight as a light emitting element, and an S-shaped inclined portion whose thickness is not changed is formed on the light guide plate from a light incident surface to a light emitting surface of the light guide plate. Since the thickness of the inclined portion is not changed, it is possible to make the pressure of resin flow at the time of performing injection molding uniform thus manufacturing the light guide plate with high accuracy.
