Abstract: A matrix is formed into a desired shape by pouring transparent liquid material into a mold. The material progresses from the liquid to the gelatinous state. Laser sculpting steps are performed when the material is still in a gelatinous condition to form small spots in the matrix. Because the material is non-solid gel when the laser beam applies its focused energy, there is no cracking or destruction. Intensity and duration of the laser pulse determine the size of the spots as does the timing in relation to the matrix material finally changing from gel to solid. Particular visual effects are produced at different degrees of solidity when sculpting. The liquid in the mold may be pressurized for removal of air bubbles after initial pouring of the matrix material and application of pressure after the laser sculpting controls the size of the spots in the finished product.
Abstract: A metal oxide dielectric film of perovskite type represented by ABO3, wherein a composition ratio between an A-element and a B-element contained in the film satisfies the following Equation (1-1), and an amount of an oxide of the A-element contained in the film satisfies the following Equation (1-2):
1<[A]/[B]≦1.1 (1-1)
where [A]/[B] represents a composition ratio between the A-element and the B-element,
(IAO/IABO3)<10−2 (1-2)
where IAO and IABO3 respectively represent (111) peak intensity of an oxide of the A-element and (100) peak intensity of the metal oxide dielectric in an X-axis diffraction spectrum.
Abstract: A hard tissue repairing material including a base material and a surface layer having a crystalline zirconia covering the base material, being characterized in that the film includes a Zr—OH group. A middle layer may be formed between the base material and the surface layer and, in such case, includes at least one element of the base material and at least one element of the surface layer having a crystalline zirconia.
Abstract: A dielectric film is formed on a free-standing conductive metal layer to form a multi-layer foil comprising a conductive metal layer, a barrier layer and a dielectric oxide layer. Such multi-layer foils are mechanically flexible, and useful for the manufacture of capacitors. Examples of barrier layers include Ni—P or Ni—Cr alloys. After a second layer of conductive metal is deposited on a dielectric oxide surface opposing the first conductive metal layer, the resulting capacitor foil is processed into a capacitor. The resulting capacitor is a surface mounted capacitor or is formed as a integrated or embedded capacitor within a circuit board.

Abstract: The invention is a method of producing a ceramics material comprising the steps of: preparing a raw powder in which alumina particles having an average particle diameter of 0.1-1.0 &mgr;are doped with at least magnesia of 0.01-1 weight % and a solution containing yttrium of 0.1-15 weight % in yttria; molding said raw powder and calcining a molding thus created; and heating the calcined molding in an atmosphere containing a hydrogen gas to create YAG which is leached to the surface to deposit YAG on the surface and sintering the molding.
Abstract: Multi-layer assemblies of polysilicon thin films having predetermined stress characteristics and techniques for forming such assemblies are disclosed. In particular, a multi-layer assembly of polysilicon thin films may be produced that has a stress level of zero, or substantially so. The multi-layer assemblies comprise at least one constituent thin film having a tensile stress and at least one constituent thin film having a compressive stress. The thin films forming the multi-layer assemblies may be disposed immediately adjacent to one another without the use of intermediate layers between the thin films. Multi-layer assemblies exhibiting selectively determinable overall bending moments are also disclosed. Selective production of overall bending moments in microstructures enables manufacture of such structures with a wide array of geometrical configurations.

Abstract: This invention provides a composite having a hydrophilic film made of amorphous titanium oxide. A film is deposited on a substrate made of, for example, glass or synthetic resin. The film is composed of amorphous titanium oxide partially having structures in which a network of Ti—O—Ti bond is broken to give Ti—OH bond terminals.
