  • Method to obtain a refractory composite material based on carbide
    Patent number: 6841119
    Abstract: A method to obtain a refractory carbide-based composite material, in particular as an article of a predetermined shape includes the following steps: molding of a porous blank from a mixture of powders of at least one carbide-forming metal and/or non-metal and at least one carbide, the amount of carbide component in the mixture of powders not exceeding 90%, heat treating the obtained porous blank in a hydrocarbonous atmosphere containing one or more hydrocarbons until the increase in its mass reaches 2-42%, thereby obtaining a semi-product, and heating the obtained semi-product in a non-oxidizing medium at a temperature of 1000-2000° C.

  • Mounting of the lids of capsules for solid state integrated circuits
    Patent number: 5198066
    Abstract: The device is intended for application by oven soldering of covers on semiconductor capsules (1) when they are still held in a fixture (2) used in a previous manufacturing step. A cover portion (3), which is applied, has a centering means (30) for centering a semiconductor capsule (1) in relation to a cover (4) hanging in a permanent magnet in the cover portion (3). After the cover portion is in place and during heating, a pusher (6) of memory metal will after changing shape press the cover (4) into place on the capsule (1) where it is soldered in place.
