Abstract: A method of picking up an electric device which is detachably connected by its underside on a mount, by means of a holding tool. First, a second mount is detachably fastened on the upper side of the electric device such that the holding force between the electric device and the second mount is greater than the holding force between the first mount and the electric device. Next, the first mount is separated from the electric device. Finally, the electric device is picked up, on its underside, from the second mount by the holding tool.

Abstract: A single furnace loading cycle technique and a ventable sintering box therefor are disclosed for the sintering of products, such as, ceramic substrates. The sintering box includes a closeable cover which is held open by collapsible or deformable or sensitive spacers in a first furnace temperature range. The sensitive spacers collapse or deform in a higher temperature range to seal closed the box and the substrates therein. Additional spacers may be used for applying weight upon the substrates at the higher temperature range. Thus, volatile agents within the substrates are permitted to escape in the first temperature range but are prevented from escaping in the higher temperature range and in situ sintering weights can be applied without removing the substrates from the furnace.

Abstract: An interconnect structure is characterized by a matrix formed of a continuous, substantially oxygen impermeable, anhygroscopic, inorganic dielectric material, having a dispersion of metal particles therein. The metal particles have an insulating layer thereon and are in abutting contact. The application of a predetermined electrical potential between spaced first and second points on the surface of the interconnect structure causes electrical breakdown of the coatings on the particles in the region between the points of application thereby irreversibly forming an electrical conduction path through the interconnect structure between the first and the second points.

The remanently magnetizable thin-film or thin-films should have a total thickness at least equal to, and preferably at least twice, the total thickness of the magnetic thin-film or thin-films of high permeability. By doing so, the marker is more reliably deactivated when the signal-blocking layer is magnetized. For even greater assurance of deactivation, the signal-blocking layer should include more than one remanently magnetizable thin-film, thus giving it a squarer B-H loop and greater assurance against false alarms.
