Abstract: An object of the invention is providing a highly reflective white material and an LED package capable of reflecting light having a peak at a wavelength of 350 nm through 800 nm with high efficiency. In order to achieve the object, a highly reflective white material of the invention includes a mixed resin of an adamantane resin having an acrylic functional group and a silicone resin; and a curative agent. Thus, the white reflective material is less degraded through UV irradiation and exhibits high reflectance in a low wavelength region.

Abstract: An inflow nozzle is disposed perpendicularly to plate-shaped fins of a heat-receiving section which is caused to face a heat-generating body to be cooled to draw heat therefrom, and portions of the plate-shaped fins are formed in a substantially V-shape or a substantially U-shape. Moreover, by selecting a proper dimension ratio of the thickness of a heat-receiving plate facing the heat-generating body and the length of the heat generating body, the heat absorption performance of the cooling device can be improved, and the cooling of the electronic component which generates high-temperature heat can be performed efficiently.

Abstract: The present invention provides the exhaust gas purification catalysts containing a first catalyst component comprising an inorganic oxide having heat resistance and a transition metal oxide supported on the surface of the inorganic oxide and a second catalyst comprising at least one alkali metal sulfate, which have a high catalytic activity for the burning of particulates.

Abstract: A catalyst for exhaust gas purification characterized by high catalytic activity, heat resistance, and toxin resistance includes a metal oxide and at least one alkali metal sulfate or at least one alkaline earth metal sulfate. The process for producing the catalyst includes mixing the metal oxide with an aqueous solution of the sulfate, evaporating the mixture to dryness, and heat-treating the resultant mixed powder. An exhaust gas purifying apparatus includes an exhaust gas purifying filter having a high exhaust gas purification rate and an excellent durability. The filter includes a ceramic filter with a heat-resistant coating layer thereon for support of the catalyst.

Abstract: An antenna element is composed by molding with an armor, and therefore if a slight deformation is caused by external force, the antenna characteristics are hardly changed. In particular, by the helicoid constitution of the antenna, changes of the pitch of antenna element and coil length are small, so that an antenna of excellent characteristics may be obtained. Moreover, by forming a hollow part in the armor and holding part of the helicoid part by the armor, more excellent antenna characteristics may be obtained.
