Abstract: A chip carrier is disclosed which includes a chip carrier substrate and at least one semiconductor chip mounted in a flip chip configuration, via solder balls, on a circuitized surface of the chip carrier substrate. The solder balls are encapsulated in a first encapsulant having a composition which includes an epoxy. In addition, at least a portion of the circuitry on the circuitized surface is encapsulated in a second encapsulant having a composition which includes a urethane, and which composition is chosen so that the second encapsulant exhibits a modulus of elasticity which is equal to or less than about 10,000 psi. As a consequence, the second encapsulant exhibits neither internal cracks, nor interfacial cracks at the interface with the first encapsulant, nor does the second encapsulant delaminate from the circuitized surface, when the chip carrier is thermally cycled.

Abstract: A base loaded antenna is provided, which securely holds the inductive loading coil of the antenna while minimizing capacitive coupling of adjacent coil turns. A coil support has fins with grooves that hold the coil, so most of the space between adjacent coil turns contains only air. A cover surrounds the coil, and the coil support is loaded in tension while the cover is loaded in corresponding compression. A base on which the coil support and cover are mounted, is held to a vehicle sheet metal body by a star plate that lies on the underside of the sheet metal. The star plate has bent-up peripheral portions that "dig" into the sheet metal to make an electrical ground connection therewith, and a flat middle for making electrical and mechanical connections to outer coaxial conductors.

Abstract: A system for vacuum depositing a material onto a sample having a surface recess, such as a hole or channel, therein. The system includes a vacuum chamber capable of attaining a high vacuum and a vacuum deposition source in the chamber for emitting atoms. An energy source is connected to the vacuum deposition source to initiate emission of the atoms therefrom. A sample having an upper surface disposed in the vacuum chamber opposite the vacuum deposition source is adapted to receive the atoms emitted from the vacuum deposition source. The sample has a surface recess therein with a wall substantially perpendicular to the plane of the sample. Finally, a component for eliminating undesirable depositing angles of atoms is disposed intermediate the vacuum deposition source and the sample in order to improve the ratio of recess wall to sample surface deposition.

Abstract: In an inverter-synchronous machine drive system wherein a synchronous machine is excited by an inverter from a source of direct current, a pair of controlled bidirectional conduction means are serially coupled across the source of direct current potential, and are coupled at their junction through a commutating capacitor to the machine neutral terminal. Each controlled bidirectional conduction means, together with corresponding phase connected thyristor within the inverter, is correspondingly gated in a predetermined sequence so as to cause alternating voltage to be applied across each corresponding machine phase for initial machine excitation.

Abstract: Operation of a separately excited DC motor at maximum efficiency is achieved by continuously varying armature and field current in accordance with an operator-commanded motor torque amplitude signal. Armature current is varied in accordance with its magnitude of deviation from an armature current command signal which is generated in accordance with a predetermined relationship between the operator-commanded torque amplitude signal and field current. Field current is simultaneously varied in accordance with its magnitude of deviation from a field current command signal which is generated in accordance with magnitude of the armature current command signal. Since the motor is thus provided with the optimum field at all times, maximum motor efficiency is achieved irrespective of loading or speed.

Abstract: A high current switching transistor controlling a load in its collector circuit receives from a drive circuit sufficient base current necessary to render the transistor conductive. A low loss inductor and switching means are connected to the base of the transistor such that when switching means are rendered nonconductive, current from the inductor flows into the base of the transistor to render it conductive, thus energizing the load.Regulating means coupled between a source of relatively high DC potential and the inductor together with unidirectional feedback path means provide a continuous current into the inductor such that when regulating means are substantially nonconductive, current is diverted away from the base of the high current transistor and circulates through the unidirectional feedback path and low loss inductor.

Abstract: A direct current motor control system for generating current command signals to a unidirectional armature controller and a bidirectional field controller. A motor speed command is compared with the actual motor speed to generate a speed error signal. The system generates a current command signal from the average of the speed error signal wherein the current command signal is proportional to the square root of the desired motor torque. The absolute value of the current command signal is the input to the armature controller and the field controller receives the current command signal wherein the polarity of the signal determines the direction of current flow in the field winding for controlling the direction of rotation of the motor.
