Abstract: PROBLEM TO BE SOLVED: To provide an electrophoretic display and a method of producing that display. SOLUTION: The invention provide a constitution foranelectrophoretic display device which is effective to substantially prevent aggregation of dye particles. A medium of a suspension liquid is held between first and second electrodes to form an electrophoretic display cell. A plurality of dye particles are dispersed in the medium of the suspension liquid, where a plurality of mechanical members protrude. The member is sufficiently small so that a plurality of the members can exist in the minimum visible region of the cell. Because the mechanical members can be produced separately from the other parts of the display, the material for the production and treatment conditions can be flexibly determined.

Abstract: PROBLEM TO BE SOLVED: To provide a material exhibiting periodicity of micrometer scale, e.g. a photon bandgap material. SOLUTION: This process comprises a step for providing a template containing colloidal crystals and a step for introducing a molten material into voids in crystal lattices. In usual, the introduction step is carried out by exposing the crystals and the molten material to a pressurized environment so that the molten material is forcedly introduced into the voids in the crystals. Then, the material is cooled down and the colloidal crystalline grains are removed by heat etching or by decomposing. The resulting material forms a homogeneous structure of high-density. The void accumulation is filled with continuous liquid phase conventionally, and this favorable structure prevents the formation of vacancies and inhomogeneity in the conventional final structure.

Abstract: A structure, e.g., a photonic band gap material, exhibiting substantial periodicity on a micron scale is provided. Fabrication involves the steps of providing a template comprising a colloidal crystal, placing the template in an electrolytic solution, electrochemically forming a lattice material, e.g., a high refractive index material, on the colloidal crystal, and then removing the colloidal crystal particles to form the desired structure. The electrodeposition provides a dense, uniform lattice, because formation of the lattice material begins near a conductive substrate, for example, and growth occurs substantially along a plane moving in a single direction, e.g., normal to the conductive substrate. Moreover, because the electrochemically grown lattice is a three-dimensionally interconnected solid, there is very little shrinkage upon subsequent treatment.

Abstract: A structure exhibiting substantial periodicity on a micron scale, e.g., a photonic band gap material, is provided. The structure is fabricated by a process involving the steps of providing a template comprising a colloidal crystal, and introducing into the colloidal crystal a liquid dispersion of nanoparticles. The resulting composite is treated, e.g., dried, to form a cohesive structure from the nanoparticles, and the colloidal crystal particles are removed to form the ordered structure.

Abstract: An improved recording medium is provided having a rigid porous matrix containing a photoimageable system. In contrast to previous media containing porous matrices, the invention allows readable holograms to be written in a medium without the need for solvent processing steps subsequent to irradiation. Due to the rigid nature of the matrix, polymerization and/or diffusion during formation of each individual hologram induces only a small level of Bragg detuning. Temperature fluctuations similarly induce only a small Bragg shift. Improved archival life of recorded holograms and improved fidelity of read-out, as well as improved optical elements, are thereby attained. And the avoidance of solvent processing makes the process of recording holograms far easier than in previous porous matrix-based media.

Abstract: A structure, e.g., a photonic band gap material, is provided exhibiting substantial periodicity on a micron scale, along with desirable density and mechanical integrity. A template comprising a colloidal crystal is provided, and into the interstitial space of the crystal is introduced a molten material. The introduction is typically performed and/or promoted by subjecting the crystal and molten material to a pressurized environment, which tends to force the molten material through the interstitial space of the crystal. The material is cooled, and the colloidal crystal particles are typically removed, e.g., by heating, etching, or dissolving. The resulting material constitutes a highly uniform, high-density structure, due to the invention's use of a continuous liquid phase to fill the void volume, as opposed to techniques that result in porosity and non-uniformities within the final structure.
