Abstract: A celebratory balloon fabricated from polymeric films have a deposited insularly array of metal which may be further enhanced by polymer encapsulation of the metal. When the balloon is inflated with an admixture of helium and an electronegative gas, the balloon demonstrates to have high breakdown strength across the balloon surface and within the balloon through the inflation gas. The gas mixture further enhances the breakdown strength of the inflation gas by increasing the onset voltage of corona, streamers and spark breakdown. The admixture gas also enhances the breakdown strength of metal-free galloons such as non-metalized balloons, clear balloons, and latex balloons.

Abstract: Beam-lead chips are held to a magnetic carrier and incident light reflected by the shiny beam leads is seen by a TV camera. The electronic image is normalized and insignificant reflections are ignored. An X-Y table moves the magnetic carrier to bring the next chip within the field of view of the camera. The table then moves the carrier in two dimensions while seeking the reflections of specific beam leads. The locations of the edges of the desired beam leads are noted, and the X-Y table quickly moves to its final position midway between the noted edges. A subtraction of the X and Y data results in a .theta. correction signal. The chip is then vacuum lifted from the magnetic carrier by a prior art bonding head. Meanwhile, a substrate has been similarly positioned using another TV camera. The bonding head moves the chip to the substrate and bonds the beam leads.
