Rugged module package for thin film hybrid microcircuits incorporated a rigid, thermally conductive support structure, which serves as a heat sink, and a lead wire block in which T-shaped electrical connectors are potted. It protects the circuitry from shock and vibration loads, dissipates internal heat, and simplifies electrical connections between adjacent modules.
Multiple chip custom block, MIC construction is used to fabricate an ultracompact, low-power astable multivibrator. The design provides a multivibrator that free runs, eliminating lockup, is triggerable, pulling into synchronization with an external signal source, and permits design flexibility for controlling the frequency variations with temperature.

Heat treating insulating crystals in gaseous hydrogen atmosphere produce resistive device which is temperature-independent from 77 to 295 degrees K. Increasing the concentration of hydrogen within the crystal yields semiconductor, hybrid, and metallic conduction characteristics which are combined with a depletion layer at the surface.
