Abstract: A semiconductor light emitting device comprises: a semiconductor light emitting element that emits light of a first wavelength; at least two kinds of phosphors that absorb the light of the first wavelength and then emit wavelength-converted light; sealing resin in which the at least two kinds of phosphors are dispersed and the semiconductor light emitting element is embedded; and binder resin. Combined bodies in which the at least two kinds of phosphors are combined by the binder resin are dispersed in the sealing resin.

Abstract: A light emitting device includes a plurality of chips efficiently disposed in a limited space of an opening that has an approximately elliptical or elongate-circular opening shape. The device includes a lead having a slit formed between a portion for bonding a wire to and a portion for mounting chips on, thereby to prevent extrusion of an adhesive and eliminate defective bonding.

Abstract: A light emitting device includes a semiconductor light emitting element and a silicone resin provided to embed said semiconductor light emitting element, where silicone resin has a hardness not lower than 50 in JISA value. The use of a silicone resin as the resin for sealing the semiconductor light emitting elements instead of conventional epoxy resins can reduce the possibility of cracks, exfoliation, breakage of wire, etc. that were often caused by conventional epoxy resins, and can also improve the resistance to whether and light.

Abstract: A support structure for a drive source such as a motor of the blower is disclosed in which the generation of noise caused by the vibration of the motor is suppressed. The flange of a support member has a low-stiffness portion having a thickness smaller than a high-stiffness portion of the same flange. The low-stiffness portion is thus vibrated more easily than the high-stiffness portion. When the motor vibrates, therefore, the vibration rate of the low-stiffness portion increases beyond that of the high-stiffness portion, so that the low-stiffness portion vibrates considerably. The motor vibration is thus absorbed by the flange (support member) and the transmission of the motor vibration to a casing can be suppressed. As a result, the area of the sound source of the blower is decreased as a whole, thereby making it possible to suppress the generation of noise caused by the vibration of the motor.

Abstract: A cosmetic containing a solvent extract of trapae fructus according to the present invention has a large skin depigmental action, and inhibits a hyaluronidase action. In consequence, the lubricity and flexibility of the skin are maintained and aging is also prevented. In addition, the cosmetic of the present invention inhibits the production of active oxygen and has antioxydation, and therefore the oxidation of fatty acids is prevented, so that the production of peroxides is suppressed, which leads to the prevention of the aging of the skin. Therefore, the cosmetic of the present invention prevents rough skin and keep skin luster and skin elasticity in a good state. The safety of the trapae fructus to the skin of humans has been assured by using it as food for a long period of time.
