Abstract: A double master mask process for fabricating semiconductor integrated circuits is provided in which selectively etchable dielectric layers and ion implanted resistors are used to form dense integrated circuits with a minimum number of critical alignments. A first silicon dioxide silicon nitride layer used in conjunction with a first master photomask defines a base region and an isolation region which are self-aligned with respect to each other and with respect to resistor contact regions. After isolation and base diffusion, the first oxide/nitride layer is stripped away and a second oxide/nitride layer is grown. Using a photoresist mask, a predeposition layer for the resistor is then formed using ion implantation through the oxide/nitride layers. A second master photomask allows the formation of collector and emitter regions and base and resistor contact which are self-aligned with respect to each other.

Abstract: An ultrasonic or microwave intrusion detection system uses a transmitter having one or more transducers or antennas for maintaining wave fields in the area to be protected and fed by one or more transducers or antennas which detects echo reflections of the energy from within the area. The receiver employs two mixers energized to be mixed with the echo signals and a portion of the energy from the transmitter, one of the mixers receiving such transmitter energy with 90.degree. phase shift relative to the other mixer. The outputs of the two mixers thus are in quadrature phase relative to each other and define a rotating vector which contains the information relating to the echo signals. The product of these quadrature signals obtained by multiplying them together is processed continuously to obtain target information in the presence of substantially larger clutter return signals and other interference.

Abstract: In accordance with an embodiment of the invention, an array of apertured flat plates support the tubes in a heat exchanger. Each aperture has at least three bights that provide individual fluid passageways when the associated tube is lodged in place. At least three inwardly protruding members that separate the bights restrain tube movement. Each of these members define arcs of a circle that has a diameter which is only slightly larger than the outside diameter of the respective tube. During heat exchanger assembly, this slightly larger diameter of the circle defined by the inwardly protruding members accommodates departures in the tubing from a perfectly straight condition. In operation, the individual tubes will tend to lay against one or two of the members in each aperture in almost line contact to prevent "crevice corrosion.
