A highly productive method for sealing substrates with the use of glass frit is provided. A method for sealing substrates with the use of glass frit, which can be used for a substrate provided with a material having low heat resistance, is provided. A highly airtight sealed body which is manufactured by such a method is provided. A light-emitting device having high productivity and high reliability and a manufacturing method thereof are provided. A heat generation layer containing a conductive material which generates heat by induction heating is formed to overlap with a region where a paste including a frit material and a binder is applied. Alternatively, a conductive material which generates heat by induction heating is added to the paste itself. The paste is locally heated by induction heating to remove the binder included in the paste.

A method and apparatus for forming laminate composite structures. At least two laminae, each containing electrically conductive reinforcing fibers, are placed upon each other in contacting relationship to form a generally layered structure. The layered structure may be subjected to heat to conductively transfer heat through the layered structure and thereby improve the surface contact between two laminae. The layered structure is volumetrically heated by inductively transferring energy to the electrically conductive reinforcing fibers. The heated, layered structure is consolidated, such as by applying pressure and reducing the temperature of the layered structure. The consolidated structure is then quenched by rapidly cooling the consolidated structure in a directionally controlled manner about a midplane thereof.

A method of forming a laminate for use in the production of printed circuit boards, comprising the steps of: a) forming a component comprised of a sheet of copper foil and a sheet of metal, the sheet of copper foil having an essentially uncontaminated surface facing an essentially uncontaminated surface of the sheet of metal, the surfaces of the sheets being in unattached contact with each other in an area that defines a substantially uncontaminated zone; b) applying a preformed adhesive film formed of a substantially uncured polymeric material onto an exposed surface of the copper foil, the adhesive film having a first surface and a second surface, the film being attached to the component with the first surface in contact with an exposed surface of the copper foil; and c) curing the adhesive film, wherein the second surface of the adhesive film is at least partially uncured.

An apparatus for forming and consolidating organic matrix composites. An organic matrix composite panel comprising laid-up prepregs is placed between sheets of a susceptor material that is susceptible to inductive heating to form a workpiece. The resulting workpiece is placed within upper and lower dies formed of a material that is not susceptible to inductive heating. An induction coil embedded within the dies is energized and inductively heats the susceptor sheets surrounding the panel. The sheets in turn conductively heat the organic matrix composite panel. A pressure zone between the workpiece and one of the dies is pressurized to form the workpiece to the contour of a forming surface on one of the dies. The pressure in the pressure zone is maintained on the workpiece until the organic matrix composite panel is fully consolidated and formed.

Capitalizing on the unique feature of our induction heating workcell that permits rapid and controlled heating and cooling of a workpiece within a wide temperature range allows us to combine manufacturing into a single heating cycle to save time, energy, capital, touch labor, and factory space. For example, we can combine superplastic forming (SPF) with annealing two operations that occur at temperatures that differ by about 150-200.degree. F. (85-105.degree. C.) or more, to produce quality parts. We mill parts flat to simplify their machining, form them to complex curvature, and anneal them.

Multisheet SPF parts with braze joints at selected locations are produced with improved energy efficiency and at lower cost. The parts include a core defined with intermittent welds between two or more core sheets and aerodynamically smooth facing sheets brazed to the core. The manufacturing process includes heating the multisheet pack to its superplastic forming range below the melting point of the braze alloy, superplastically forming the pack to define braze joints having unmelted braze alloy; increasing the temperature to the braze temperature of the braze alloy, and cooling the pack below the superplastic range to freeze the braze alloy in the braze joint.

Quality thermoplastic fusion welds are formed in prefabricated resin composite parts by aligning a susceptor along a bondline between parts with the induction coil segments of a solenoid induction coil along the centerline of the coil. Energizing the coil heats the susceptor to form the weld at the bondline. For this operation, our induction heating workcell users complementary dies that define a central cavity with an oval pattern of induction cool segments surrounding all faces of the cavity where the preform composite parts and susceptor are positioned.

For forming or consolidating organic matrix composites, an organic matrix composite panel is placed between sheets of a susceptor material that is susceptible to induction heating. The susceptor sheets enclose the panel and define a retort. Peripheral gaskets temporarily seal the retort when the retort is placed within upper and lower dies of an induction heating workcell where the susceptor sheets are heated inductively. The sheets in turn conduct heat to the organic matrix composite panel. When heated to the desired temperature, the composite panel is consolidated and/or formed. In some circumstances, edge seal strips are used to provide electrical continuity between the upper and lower sheets in the retort. An analogous retort can be used for metal processing operations.
