  • Patent number: 10415134
    Abstract: Disclosed is a crucible that exhibits stable evaporation efficiency and durability with respect to Al, is used in an evaporation source of an electron-beam evaporator, and includes a storage unit, which includes a wall and a bottom and in which a deposition material is placed, and a wetting prevention unit that includes another wall, which is taller than the wall of the storage unit, and another bottom, and is combined with an exterior of the storage unit. The wetting prevention unit is provided so that only the wall of the storage unit is wet with Al, and accordingly, the lifespan of the crucible is lengthened. Further, contact with the ceramic material in order to prevent wetting is minimized, thereby preventing a reduction in the physical properties of the thin film due to the impurities mixed with the deposited Al.

  • Patent number: 8794950
    Abstract: A heating device for the transformation of a material, includes: a lower mold element or matrix, made of an electrically conductive material and having a molding zone for contacting with the material to be transformed; an upper element that lacks a molding zone, made of an electrically conductive material; inductor elements for generating a magnetic field that envelops the matrix and the upper element, with the matrix and the element being electrically insulated from one another during the induction heating phase so that the surfaces opposite these two elements delimit an air gap in which the magnetic field that induces currents circulates at the surface of the molding zone of the matrix, thus making it possible to localize the action of the inductors at the interface of the molding zone/material to be transformed; and deformable pressure element, arranged between the matrix and the upper element, able to exert uniform pressure on the material to be transformed.

  • Patent number: 8684721
    Abstract: There are provided an apparatus and an associated method for manufacturing superplastically formed structural assemblies from preforms. The apparatus includes first and second co-operable dies structured to define a die cavity therebetween for at least partially receiving the preform, at least one heater in thermal communication with the die cavity for heating the preform to a forming temperature, and at least one injector in fluid communication with the die cavity. The injector is structured for injecting pressurized gas into the die cavity to urge the preform against one of the dies to form the preform into the structural assembly. Further, at least one of the injectors is structured for injecting a quenchant into the die cavity to thereby heat treat the structural assembly while distortion of the structural assembly is being at least partially restrained by at least one of the dies.

  • Publication number: 20130285292
    Abstract: A method of curing a composite material. A tool is heated using microwaves. At least a part of the composite material is shielded by reflecting microwaves away from the composite material with a shield. Heat is transferred from the tool through the shield to the composite material. The tool comprises a material which is sensitive to microwaves so that, when microwaves are incident upon the tool, some of the microwaves are absorbed by the microwave-sensitive material, thereby heating the tool.
