Circuit modules including complex multi-function circuitry on common module substrates using circuit tiles of silicon thin-films which are transferred, interconnected and packaged. The modules include integrated transfer/interconnects with extremely high density and complexity with large-area active-matrix liquid crystal displays and on-board drivers and logic in glass-based modules.
Abstract:
Thin and durable level-one and level-two integrated circuit packages are provided. Moisture-barriers may be provided to upper and/or lower surfaces of the thin level-one package. Additionally, a thin level-one package may be constructed with one or more metal layers to prevent warpage. These level-one packages are aligned in a stacked configuration to form a thin and durable horizontal level-two package. Various thermal conductors are thermally coupled to the level-two package to help dissipate heat.

Abstract:
A Cockcroft-Walton voltage multiplying circuit constructed for use in a slim hole well logging tool includes a plurality of capacitor packages having a first capacitor package, adapted to receive an input voltage, and a last capacitor package. A plurality of high voltage rectifier packages of which each rectifier package, except for a last rectifier package, are physically as well as electrically interconnected with two capacitor packages. The last rectifier package is connected to the last capacitor package so that all of the capacitor packages and all of the rectifier packages form an inline rigid body. Output terminals are connected to the last rectifier package for providing the high voltage developed by the capacitor packages and the rectifier packages in response to a received input voltage.
Abstract:
To form a compact combination structure which provides efficient cooling and ease of assembly, maintenance and repair, while reducing the number of elements necessary to be stocked for maintenance or repair purposes, the rectifier portion of the alternator-rectifier combination comprises two groups of rectifiers which are, respectively, set in openings of two disk-shaped support plates 15, 35, which have, each, ring-shaped portions 38 surrounding the shaft and radially projecting fins 39, 39'. One of the plates is formed with a hub to retain one of the bearings, the outer portion of the fins is apertured for attachment to the shell of the alternator, and additionally deformed to provide seating surfaces for accurate positioning, for example by externally applied punch marks, of the plate. An insulating spacer 43, 43' separates the two plates which are so positioned that the fins of one plate are opposite the gap between fins of the other, so that air drawn axially by a ventilating fan will cool both plates.

A semiconductor device includes a sealed vessel accommodating a semiconductor body and a heating element. When the semiconductor body is not energized, the heating unit is heated.
Abstract:
Brushless excitation systems for alternating current generators include an alternating current exciter and a rotating rectifier assembly. In such a system, the rectifier diodes of the rectifier assembly are mounted on the rim of a wheel which rotates with the exciter armature member, and the leads from the exciter winding extend along the shaft and through openings in the wheel for connection to the diodes. Supporting means are provided for the leads consisting of an elastic tubular member such as an aluminum sleeve, which extends axially from the wheel and encloses the leads. The leads are supported radially against the inner surface of the tubular member which has sufficient elasticity to permit limited radial deflection of the leads to follow the wheel when it expands radially in operation.
