A light emitting device including a blue-system semiconductor light emitting element, a green-system semiconductor light emitting element, a yellow fluorescent member which absorbs a part of blue light from the blue-system semiconductor light emitting element and emits yellow-system light as excitation light, and a red fluorescent member which absorbs a part of green light from the green-system semiconductor light emitting element and emits red-system light as excitation light.
摘要:
The planar light source of this invention comprises: a light guide plate made of a platelike, light-transmitting material formed with a reflection surface on a bottom side thereof, the reflection surface being formed by combining a plurality of kinds of reflection means; and an illuminating light source arranged opposite a light receiving side surface of the light guide plate; wherein the light guide plate has formed smooth a boundary on the reflection surface between the plurality of kinds of reflection means so as not to form any step between the adjoining reflection means. This construction prevents the formation of a dark-bright fringe pattern between the plurality of reflections means when the light source is illuminated.
摘要:
A piezoelectric panel speaker improved in frequency characteristics has a panel and a piezoelectric exciter for vibrating the panel. The exciter includes a casing and a piezoelectric exciter element accommodated in the casing. The casing has an outer surface with a part positioned proximate to and facing one side surface of the panel. The side surface of the panel has an area opposed to the part of the outer surface of the exciter. A securing layer is partially formed between the area of the panel and the part of the outer surface to secure the exciter to the panel. The securing layer is made of a material so that vibration is transmittable from the exciter to the panel.

摘要:
In a surface-mounted antenna apparatus which is surface-mounted on a circuit substrate, condenser connecting electrodes for connecting leads of a coil and a synchronous chip condenser are disposed on an upper surface of one flange provided in the surface-mounted antenna apparatus, and circuit connecting electrodes for connecting with a receiving circuit provided on the circuit substrate are disposed on a lower surface of the one flange.
摘要:
A substrate is prepared that includes substrate segments arranged in series in the X and Y directions. The substrate segments are respectively provided with circuit patterns on its one side and electrodes on the other side. Sets of IC devices including bobbins are mounted on the sides with the circuit patterns of the respective substrates. A conductor is wound around the bobbins successively to form the windings. Portions of the conductor extending between the adjacent windings are pressed against and connected to the circuit patterns to form leading and trailing ends of the windings connected to the circuit patterns. Thereafter, the substrate is severed to provide surface-mount coil packages each comprising the circuit board and the set of IC devices including the coil.
