Abstract:
A power supply for producing excitation of an X-ray tube filament of an unusually lightweight and readily portable X-ray machine is achieved through the use of multiple voltage multiplying-rectifying stages powered by a transformer driven at 25 kHz. A four amp-four volt electrical current is applied across the X-ray tube filament by the use of a multi-stage filament transformer array driven at 33 kHz. The multi-stage filament transformer array is interconnected to the multiple voltage multiplying-rectifying stage so as to limit the voltage potential between stages. The use of 25 kHz and 33 kHz driving signals eliminates cross talk between signal producing circuits.

Abstract:
A multi-tool bonder having a plurality of die heads flexibly mounted on a conveyor which spaces and moves the heads along a path which includes a plurality of die processing stations. An alignment mechanism is provided at each stationary processing station for aligning the head at a fixed position along the path at the station. A controller controls the conveyor to position the plurality of heads at the stations and controls operation of the heads at the stations.

Abstract:
An unusually lightweight and readily portable X-ray machine is achieved through the use of a multi-stage DC voltage multiplier combined with a multi-stage AC filament current stepdown transformer, incorporating unique components and subassemblies. Multi-prong clamping inter-stage connectors couple diode strings to plural capacitor array junctions and to conductors matching interstage DC potentials between multiplier stages and transformer stages. A high voltage input transformer for the multiplier incorporates dual insulating layers, a relatively thick, heat-resistant Teflon layer exhibiting extremely low dielectric losses and a thinner Epoxy layer having a tractive outer surface supporting a large plurality of fine wire secondary winding turns. A laser target selector removably mountable on the X-ray tube's projection portal illuminates a target spot to allow adjusted aiming of the X-ray beam.
