Abstract: The present invention provides: a highly transparent optical member which is formed from a silicone resin or a silicone rubber, and which has less mass change and excellent heat resistance without causing contact faults, or deterioration or contamination of the surface of other members due to adhesion to an electronic circuit or the surfaces of other members; and a production method for producing said optical member. According to the production method, the content of low-molecular-weight siloxanes D3-D20 in a optical member is reduced to an infinitesimal amount with use of a plurality of different low-molecular-weight siloxane removal steps.

Abstract: A thermoelectric conversion structure is provided which provides satisfactory heat transfer characteristics without the formation of a thermally conductive grease layer between a thermoelectric conversion module and heat transfer target members. In a thermoelectric conversion structure, a thermoelectric conversion module integrated by joining the surfaces of a thermoelectric conversion element on a high temperature side and a low temperature side to thermally conductive elastomer sheets containing a thermally conductive filler is arranged between heat transfer target members and that transfer heat to the thermoelectric conversion element, and the surfaces of the thermally conductive elastomer sheets and the corresponding surfaces of the heat transfer target members and are in direct intimate contact with each other.

Abstract: A versatile silicone resin reflective substrate which exhibits high reflectance of high luminance light from an LED light source over a wide wavelength from short wavelengths of approximately 340-500 nm, which include wavelengths from 380-400 nm near lower limit of the visible region, to longer wavelength in the infra-red region. The silicone resin reflective substrate has a reflective layer which contains a white inorganic filler powder dispersed in a three-dimensional cross linked silicone resin, the inorganic filler powder having a high reflective index than the silicone resin. The reflective layer is formed on a support body as a film, a solid, or a sheet. The silicone resin reflective substrate can be easily formed as a wiring substrate, a packaging case or the like, and can be manufactured at low cost and a high rate of production.

Abstract: An ultraviolet reflective material having high reflectance in a wavelength region from the short-wavelength ultraviolet region inclusive of 200 nm to the long-wavelength ultraviolet region inclusive of 400 nm, and in particular having high reflectance in an ultraviolet region at 200 to about 315 nm, i.e., from UVC to UVB where reflectance could not be conventionally obtained, among them particularly at 250 nm or below in the short-wavelength ultraviolet region; and does not undergo discoloration/degradation upon irradiation. Ultraviolet reflective materials have ultraviolet reflective layers containing a condensation-cured silicone resin and ultraviolet reflective filler particles of alumina, magnesium hydroxide, calcium fluoride, aluminum hydroxide, aluminum nitride, and the like, and has a reflectance of 60% or more at a wavelength of 405 nm.

Abstract: An ultraviolet LED optical member has high transmittance in an ultraviolet range, is stable even by long-term use and has excellent reliability. The ultraviolet LED optical member exhibits optical characteristics in which the average transmittance at wavelengths from 200 to 300 nm is 50% or more by having an optical member made of an organic resin. The optical member for this ultraviolet LED optical member preferably exhibits optical characteristics in which the transmittance of at least any wavelength from 200 to 250 nm is at least 60%.

Abstract: A slidable rubber material that has an amino-modified interfacial layer that does not affect the compression set. Although the slidable rubber material includes a rubber component such as a butyl rubber or halogenated butyl rubber etc. having the low-compression set, which contains a vulcanization agent such as a nitrogen/sulfur compound or a vulcanizing auxiliary agent, the rubber part is coated with a silicone rubber layer. The slidable rubber material exhibits a slidability and resists the detachment or elution of fine particles from the coating layer. A rubber component and a vulcanization agent; an interfacial modification layer that coats the rubber part and an amino-modified silicone compound is incorporated with surface molecules of the rubber part; and a layer that coats the interfacial modification and contains solid fine particles, an addition-type or condensation-type silicone rubber in which the particles are dispersed, and a curing catalyst for silicone rubber.
