  • Patent number: 6777104
    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.

  • Patent number: 6541137
    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.

  • Patent number: 6479166
    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.

  • Patent number: 6472088
    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.
