Abstract: A self regulating heating device (12) for a mirror (10) includes a substrate (14) having an electrical buss system deposited on one surface including a plurality of interdigitated electrodes (32, 34, 36, 38) and two buss bars (16, 18). Stripes of positive temperature coefficient resistive material (40) are printed perpendicularly over the electrodes (32, 34, 36, 38) to form a plurality of heater areas (42, 44) and exposed substrate areas. A first adhesive layer (46) is deposited over the resistive stripes and exposed areas of the substrate (14) between the stripes. Preferably an electrical barrier layer (50) is secured to the adhesive layer (46) and another adhesive layer (52) on the other side of the barrier layer (50) is covered by a removable protective covering (54). The buss bars (16, 18) are tapered so that the power density at any point along their length is substantially equal to the average power density of the heater areas (42, 44).

Abstract: An automatic tracking control system has a servo loop (20), controlled by a tracking control signal, that adjusts the position of the pickup head (4) in relation to tracks scanned by the head. Adjacent-track crosstalk is extracted by a crosstalk detector (32) and envelope-­detected by a crosstalk envelope detector (36). An automatic tracking control circuit (40) varies the tracking control signal, finds a state that minimizes the crosstalk envelope, and maintains the tracking control signal at or near that state. 
     For double-deck recording systems in which one signal is recorded in surface tracks over another signal, the automatic tracking control circuit seeks a best compromise between minimizing the crosstalk envelope of one of the signals while maximixing the envelope of the other signal.

Abstract: A temperature-compliant tube for fiber optic components is inserted into the exit port of an hermetically sealed package and extends into the interior of the package. An optical fiber extends through the temperature-compliant tube and is attached to a substrate interior of the package for coupling to an optical component mounted on the substrate. The optical fiber is hermetically sealed to the interior end of the temperature-compliant tube. The thermal coefficients of expansion and lengths for the temperature-compliant tube, the optical fiber between the substrate and the interior end of the tube, and the package body between the substrate and the exterior end of the exit port are tailored to provide zero differential expansion to enable the fiber optic components to be cycled over a wide temperature range without misalignment of the fiber relative to the optical component or mechanical failure of the fiber.

Abstract: A method for fabricating interlevel contacts in semiconductor integrated circuits provides for formation of a contact opening through an insulating layer. A layer of refractory metal, or refractory metal alloy, is deposited over the surface of the integrated circuit chip. An aluminum layer is then deposited at a significantly elevated temperature, so that an aluminum/refractory metal alloy is formed at the interface between the aluminum layer and the refractory metal layer. Formation of such an alloy causes an expansion of the metal within the contact opening, thereby filling the contact opening and providing a smooth upper contour to the deposited aluminum layer.
