  • Patent number: 11971633
    Abstract: An electrode structure includes: a plurality of pixel electrodes arranged separately from each other; and a plurality of dielectric layers laminated in a first direction with respect to the plurality of pixel electrodes, in which the plurality of dielectric layers includes: a first dielectric layer that spreads over the plurality of pixel electrodes in a direction intersecting with the first direction; and a second dielectric layer that includes dielectric material having a refractive index higher than that of the first dielectric layer, sandwiches the first dielectric layer together with the plurality of pixel electrodes, and has a slit at a position overlapping space between pixel electrodes adjacent when viewed from the first direction.

  • Patent number: 10908444
    Abstract: [Object] To provide a display device, a method for producing a display device, and a display apparatus of projection type, which are capable of suppressing deterioration of image quality attributable to a depressed space between pixel electrodes. [Solving Means] A display device of the present disclosure includes pixel electrodes formed for individual pixels and an insulating film for insulation between the pixel electrodes. The insulating film is so formed as to protrude from an electrode surface between the pixel electrodes. A display apparatus of projection type of the present disclosure uses the display device of the present disclosure as a light modulator to module light from a light source. A method for producing a display device of the present disclosure having pixel electrodes formed for individual pixels and an insulating film for insulation between the pixel electrodes includes forming the insulating film as to protrude between the pixel electrodes.

  • Publication number: 20120111621
    Abstract: An object of the present invention is to provide a resin composition having excellent impregnation property into a base material and capable of producing a prepreg, metal-clad laminate and printed wiring board excellent in properties such as low warpage, flame resistance, low thermal expansion properties, drill processability and desmear resistance. A first resin composition comprises an epoxy resin, an irregular-shaped first inorganic filler and a second inorganic filler having an average particle diameter of 10 to 100 nm which is different from that of the first inorganic filler. A second resin composition comprises an epoxy resin, silicone rubber particles having an average particle diameter of 1 ?m to 10 ?m, boehmite particles having an average particle diameter of 0.2 ?m to 5 ?m, and silica nanoparticles having an average particle diameter of 10 nm to 100 nm.

  • Patent number: 7910639
    Abstract: The present invention relates generally to resin compositions having a generally halogen-free epoxy resin that can encompass a novolak epoxy resin, a curing agent and a non-halogen flame-retardant material. For some embodiments, the curing agent can be dicyandiamide and the flame retardant can be 10-benzyl-9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide. Embodiments of the current invention also relate generally to prepregs prepared from such resin compositions; and laminates prepared from such prepregs.

  • Patent number: 4929394
    Abstract: A process for compacting radioactive waste by precompressing the waste in each of capsules while filling the waste into the capsule to thereby compress the waste to the desired bulk/true density ratio under a small total pressing load and diminish damage to the inner surface of the die used, each of the capsules having a cross sectional form corresponding to a divided segment of the cross section of an HIP treatment container, then placing the capsules into the HIP treatment container, subsequently filling the HIP treatment container with a metal powder as a filler, thereafter degassing and sealing the HIP treatment container and subjecting the container to an HIP treatment in its entirety. The process precludes scattering of the radioactive substance from the waste and release of waste fragments to assure improved safety.
