  • Patent number: 8852491
    Abstract: In a method of manufacturing an electroforming mold, a first photoresist layer is formed on an upper surface of a bottom conductive film of a substrate, and the first photoresist layer is divided into a first soluble portion and a first insoluble portion. A conductive material is thermally deposited on an upper surface of the first photoresist layer within a predetermined temperature range, to thereby form an intermediate conductive film. An intermediate conductive film is patterned. A second photoresist layer is formed on an exposed upper surface of the first photoresist layer after the intermediate conductive film is removed, and on an upper surface of the intermediate conductive film remaining after patterning. The second photoresist layer is divided into a second soluble portion and a second insoluble portion. Next, the first and second photoresist layers are developed, and the first and second soluble portions are removed.

Preferably, the carbonized material has a density of at least about 1.30 g/cm3. Preferably, the composite material is formed in less than ten minutes. This is a significantly shorter time than for conventional processes, which typically take several days and achieve a lower density material. A treating component may be impregnated into the composite. Consequently, carbon composite materials having final densities of about 1.6-1.8 g/cm3 or higher are readily achieved with one or two infiltration cycles using a pitch or other carbonaceous material to fill voids in the composite and rebaking.

  • Patent number: 6001299
    Abstract: A process for electret treatment is described, involving(1) placing the dielectric article between a combination of a first ion-repulsive electrode and a first ion-attractive electrode and between a combination of a second ion-repulsive electrode and a second ion-attractive electrode, under a specified arrangement;(2) supplying a first positive ion and a first negative ion from a first ion generating means between the dielectric article and the first ion-repulsive electrode, the first ion generating means being selected from an alternating current surface discharge element and an alternating current corona-type ion generating element;(3) applying a direct current voltage between the first ion-repulsive electrode and the first ion-attractive electrode to produce a first potential difference therebetween, whereby only one of the first positive and negative ions is moved in a specified direction, and is transferred on the dielectric article;(4) supplying a second positive ion and a second negative ion from a sec

  • Patent number: 5997781
    Abstract: Disclosed is a process for the production of an injection-expansion molded, thermoplastic resin product. The process comprises a gas dissolving step, a cooling step, a metering and injection step, and an expansion controlling step. Specifically, a thermoplastic resin is molten in a continuous plasticator (1), supercritical carbon dioxide and/or nitrogen is added as a blowing agent, and the blowing agent and the thermoplastic resin are formed into a mutually-dissolved state. The resultant molten resin composition is cooled within the plasticator while maintaining a pressure equal to or higher than a critical pressure of the blowing agent. The thus-cooled molten resin composition is metered by an injector (7) and is filled in a mold (8). An internal pressure of the mold is lowered beyond the critical pressure of the blowing agent to produce cell nuclei, whereby the cell diameter is controlled. The blowing agent is maintained in a supercritical state up to the metering and injection step.

  • Patent number: 5972257
    Abstract: A process for making a foamed shoe sole includes (a)forming at least one unexpanded blank in at least one first mold by introducing thereinto a resinous molding composition, which includes an agent capable of expanding and cross-linking the resinous molding composition, at a temperature lower than that which can cause the composition to expand and cross-link; b) trimming the unexpanded blank to remove flash and inspecting the weight and size of the unexpanded blank; and (c) placing in a second mold the unexpanded blank having a predetermined weight and size and heating the unexpanded blank under pressure at a high temperature sufficient to cause the unexpanded blank to undergo expansion and cross-linking, whereby the sole so produced has good cross-linking characteristics and retains exactly the shape and size of the mold cavity of the second mold. Preferably, the resinous composition contains polyethylene vinyl acetate.
