  • Patent number: 7608315
    Abstract: A high thermal conduction insulator exhibiting thermal conductivity, insulating properties and heat radiating properties is produced by supplying a molding material composed of an insulating resin, a diamagnetic material powder and a paramagnetic material (inclusive of ferromagnetic material) powder, and exhibiting fluidity into a mold, and applying a magnetic field to the molding material in the mold to orient clusters, each being composed of diamagnetic material particles of the diamagnetic material powder, which are joined together like a chain, along directions of lines of a magnetic force, and draw the paramagnetic material (inclusive of ferromagnetic material) powder with the magnetic force along one of mold surfaces of the mold, thereby forming a heat radiating layer. Heat transmitted from a facing member to one surface of the insulator is speedily transmitted to the other surface thereof via the clusters, and is effectively radiated from the heat radiating layer existing in the other surface.

  • Publication number: 20090082525
    Abstract: A metal-resin composite molding is composed of a metal portion and a resin portion. The surface of the metal portion has silanol groups, and the synthetic resin contains an adhesive modifier having adhesive functional groups interacting with the silanol groups. The metal portion and resin portion are bonded together through the interaction between the silanol group and adhesive functional group. The method for manufacturing the metal-resin composite molding includes a step of applying silanol groups to the surface of the metal portion, a step of adding an adhesive modifier having adhesive functional groups interacting with the silanol groups to the synthetic resin thereby producing a molding material, and a step of arranging the metal portion as an insert in a mold for resin molding, melting and forming the molding material in the mold into a resin portion, and at the same time bonding the resin portion to the metal portion through the interaction between the silanol groups and adhesive functional groups.

  • Patent number: 6712492
    Abstract: The present invention provides a spread illuminating apparatus which can ensure uniform brightness over its entire screen. A light reflection-diffusion layer is formed on a light conductive member at a face provided with an optical path conversion means. Light emitted from spot-like light sources is reflected efficiently by the light reflection-diffusion layer toward a transparent substrate, and light intensity degrades in a substantially linear manner with the increase in distance from respective spot-like light sources. Sharp change of brightness on an observation surface can be prevented due to the light intensity degrading linearly.
