A flexible Peltier device in which emitting heat conversion properties between Peltier elements and an object transferring heat may be improved and a flexible heat-emitting sheet having the Peltier elements bonded thereto may be bent without worrying the separation there between. A flexible Peltier device includes a single or plural Peltier element which is disposed on one surface side of a heat-emitting sheet having flexibility made from heat-conductive rubber containing a heat conductive filler and each semiconductor element which has a heating side and a cooling side and composes the Peltier element at least one of the heating side and the cooling side is bonded integrally to the heat-emitting sheet by a direct covalent bond and/or by an indirect covalent bond through a molecular adhesive at active groups existing on each other surfaces.

Flexible peltier device and temperature regulation apparatus

A base material for adhesion to be adhered to a solid body comprising;

Base material for adhesion and silicone rubber-adhered article using thereof

This invention relates to a method of producing a molded transparent covering member. The steps of the method comprise providing a silicon rubber material and a fluorescent substance together to form a material to be molded in a space between an inner surface of an upper mold and an outer surface of a lower mold; sand-blasting at least one of the inner surface of said upper mold and the outer surface of the lower mold; and injecting the material into the space formed between upper mold and the lower mold.

Method of molding a transparent coating member for light-emitting diodes

An LED device is provided that has an excellent color rendering property and no toxicity and does not increase production costs more than necessary. A covering member is also provided used for such a device. The LED device comprises a light-emitting element for emitting light in a blue to green region and a fluorescent substance containing a red phosphor for converting the wavelength of the light emitted from the light-emitting element to another wavelength. The red phosphor is CaS activated by Eu or a phosphor expressed by the general formula AEu Ln B O , wherein A is an element selected from the group consisting of Li, K, Na and Ag; Ln is an element selected from the group consisting of Y, La and Gd; and B is W or Mo; and x is number equal to or larger than 0, but smaller than 1.

Light-emitting diode device

A novel method of producing a porous product is provided, including the steps of: preparing a molded product by subjecting a molding material comprising a polymer component and a pore-forming agent dispersed in the polymer component, the pore-forming agent assuming a solid state at a room temperature, to molding at a temperature which causes the pore-forming agent to melt; and soaking the molded product with a solvent which dissolves the pore-forming agent but fails to dissolve the polymer component, to form pores.

Method of producing a porous product

This invention relates to a transparent coating member mountable on a light-emitting diode including a fluorescent substance and a light diffusion substance including calcium carbonate in order to reduce color variation at various locations of a transparent coating member and also reduce manufacturing costs of the transparent coating member without significantly lower the level of chromaticity. Furthermore, this invention relates to a transparent coating member mountable on a light-emitting diode (LED) including a fluorescent substance and a light storing pigment. This structure allows an exhibition of afterglow of the transparent coating member after turning off the light in a room so that locating the position of the transparent coating member is made easier thereafter. The light diffusion substance and the light storing pigment can be added to the transparent coating member to acquire both advantages derived from respective substances.
