Abstract: A differential amplifier with improved linearity is disclosed. The amplifier includes a circuit comprised of two emitter-coupled pairs (10,20), each pair (10,20) being formed by two transistors (Q₁,Q₂;Q₃ Q₄), with connections between corresponding collectors (11,13;12,14), and constant voltage sources (E₁,E₂) for producing offsets between corresponding bases (1,3;2,4) of the emitter-coupled pairs (10,20). The improved linearity is achieved by obtaining outputs as sums of collector currents with offsets. The emitter areas of the transistors can be of the minimum size available. This feature, when combined with the use of emitter-followers as the constant voltage sources (E₁,E₂), enable the differential amplifier to achieve a high S/N ratio, a good high-frequency characteristic, a high direct current gain, and a high-speed operation capability along with the improved linearity.

Abstract: A process for manufacturing GaAs FET's having refractory metal gates provides for reducing the size of the gate relative to a mask by an etch sequence which results in precisely controlled and repeatable self-limited undercutting of the mask. A reactive ion etch of the refractory metal in a CF₄O₂ plasma containing an inert gas provides the self-­limiting undercut at a pressure in the range of 175-­250 mTorr when the power is less than 0.15 W/cm². Preceding the undercut, an anisotropic RIE in a CF₄ plasma can be employed to clear unmasked areas of the refractory metal and an initial sputter cleaning in argon improves the quality of the initial etch.

Abstract: A method of and apparatus for recovering the latent heat of condensation of moisture in the exhaust gases resulting from the burning of fuel in a heating installation, in which sensible heat is recovered by passing the gases through a heat-exchanger (18) and then the gases are passed through a two-stage condensing first heat exchanger (19,20), where the moisture of combustion is condensed to form droplets. The droplets are extracted from the gas flow by turning the gas flow path through 180° in a plenum chamber 23, and also by passing the gases through a droplet extracter 21 disposed downstream of the heat exchanger 20. The gases are then passed through a second heat exchanger 22 where the gases are re-heated to a temperature above the dew point thereof. The sensible and condensing heat exchangers are supplied with liquid heat exchange medium at a suitably low temperature, such as boiler feed or make-up water (26), whereas the re-heat heat exchanger (22) is supplied with relatively hot heat exchange medium, such as water heated by a boiler. Alternatively, at least a portion of the medium passed through the sensible and condensing heat exchangers may thereafter be passed through the re-heat heat exchanger.
