Platform and method for aligning the same for various aircraft orientation systems, such as inertial navigation, weather radar, flux gate compsss, etc. by integrated alignment, which is achieved by setting a prime reference position within the aircraft from fixed aircraft body structural points and respectively setting all other systems platforms from that prime position using a reference transfer gyro unit.

In the manufacture of a pattern of an integrated circuit, a reference mark is detected by an electron beam scan to correctly determine the position of the pattern on each semiconductor chip, or to correctly combine the patterns of circuit elements. The reference mark may also be used to locate defects of the semiconductor material so as to avoid defective regions.

An insulated baseboard has a power bus line and a ground bus line molded therein. Extending downwardly through the baseboard from the bus lines are wiring terminals. A plurality of openings are molded into the baseboard. Fitted into the openings are a plurality of contactors, the top ends of which have means to engage terminals of the integrated circuits, and the lower ends of which extend downwardly through the baseboards. On opposite ends of the bus lines are formed terminals for attachment to...

A carrier for dual-in-line integrated circuit package having a rigid flat body is provided with retention means including an opposite pair of cantilever fingers integrally formed in opposite walls of the carrier and rearwardly extending therefrom in elongated form and at an acute angle with body-engaging surfaces provided with a plurality of rearwardly spaced-apart detents to accommodate bodies of differing thicknesses. The cantilever fingers are adapted to be deflected toward the walls by inser...

Monolithic integrated circuits are made utilizing various ion implantation techniques for making diodes, transistors, resistors, capacitors, underpass connections, sub-collector junctions, etc., and for altering impurity profiles, gold doping, trimming resistance values, altering junctions depth, and isolating regions.

An integrated circuit having a laminated bipolar transistor with multi-emers respectively serially connected to a plurality of deep depletion field effect transistors and/or inversion channel field effect transistors. The integrated circuit has a common layer functioning as both the drain of one of the field effect transistors and an emitter of the bipolar transistor. In operation the field effect transistors conduct currents in series with the respective emitters of the bipolar transistor. In a...

An integrated electrical control device in which an electrical coil and connectors therefor are embedded in a body of plastic or other relatively rigid nonconducting material, and a switch disposed in a cavity in said body interconnects said conductor members and is adapted to be operated by an armature held by the core of said coil. The switch may consist of a leaf spring rigidly connected to one of said conductor members and yieldably connected to the other of the conductor members, and is ope...

An integrated freewheel mechanism characterized in that it comprises between an outer race and an inner race a plurality of rolling elements and a plurality of wedging cams having their front and back surfaces consist at least partially of parallel planes, the surfaces of said cams which engage said inner and outer races being at least partially cylindrical, said cams being each disposed between two adjacent rolling elements and urged for engagement with said inner race through resilient means.

Active materials having substantially time constant, spatially alternating variations in the propagation characteristics thereof produce laser oscillations when excited above a threshold of oscillation.

This disclosure relates to an arrangement to be used in conjunction with spaced instruments whereby the indications of one of the instruments may be in effect superposed on another instrument while all of the instruments remain unimpaired and entirely readable and usable at all times in their intended manner.
