    Abstract: Broadly, the present invention is directed to improving a chemical vapor phase deposition (CVD) method for synthesis of diamond wherein a hydrocarbon/hydrogen gaseous mixture is subjected to a combustion flame in the presence of oxygen to at least partially decompose the gaseous mixture to form CVD diamond. The improvement in process comprises subjecting said combustion flame to one or more of dielectric heating, d.c. discharge, or a.c. discharge. Dielectric heating can be accomplished by subjecting the combustion flame to microwave (MW) frequency discharge or radiofrequency (RF) discharge. By superimposing dielectric heating or d.c./a.c. discharge plasma generation on combustion flame process, the carbon utilization rate of the combustion flame process should improve substantially. As noted above, given the low carbon utilization rate for combustion flame techniques already, small percentage improvements in the carbon utilization rates translate into substantial cost savings in generation of CVD diamond by such combustion flame technique.

    Abstract: Diamond is produced by chemical vapor deposition on a substrate by hot filament activation of a hydrogen-hydrocarbon gas mixture. An edge of the substrate faces the filament at a distance; therefrom up to about 1 mm. and preferably about 0.3-0.7 mm., and the substrate is moved relative to the filament to maintain this spacing as diamond forms thereon. Diamond formation proceeds at an improved rate, and in single crystal configuration under certain conditions.

    Abstract: Surgery is performed with pulsed heat means that selectively destroys tissue in a region within a patient. The size of the region destroyed is dependent upon the frequency of the pulses of the pulsed heat means and thermal conductivity of the tissue of the patient. The pulsed heat means can be a coherent optical source that is guided by laser fiber to the tissue to be destroyed. In another embodiment the pulsed heat means is a focussed ultrasound transducer that dissipates ultrasonic energy at a focal point within the region of tissue to be destroyed. A magnetic resonance imaging system employing a temperature sensitive pulse sequence creates an image of the tissue and the region being heated to allow a surgeon to alter the position of the pulsed heat means or vary the pulse frequency.

    Abstract: A conductor is provided through a narrow bore hole of a wafer. The hole has a length-to-diameter ratio in excess of six. The conductor is formed by condensation of metal vapor generated at the bottom of said hole by a spark. The spark is generated between a vaporizable metal at the bottom of the hole and a thin electrode disposed above the hole from a conventional automobile coil and battery operating through a mercury switch.

    Abstract: In the electromigration process, liquid metal inclusions are migrated into or through bodies of semiconductor material by an electrical potential gradient driving force. The method of this invention provides anode and cathode connections generally useful in the practice of electromigration and connections which are especially useful in circumventing the adverse effects of several types of rectifying junctions encountered in the practice of electromigration.
