A magnetic resonance (MR) surgery system facilitates surgery with a focussed ultrasound transducer that selectively destroys tissue in a region within a subject. The focussed energy transducer dissipates energy at a focal point within the region of tissue to be destroyed. A non-magnetic positioning device having a vertical dimension small enough to fit easily within the bore of an MR magnet moves an energy transducer in a limited vertical space. The positioning device employs a plurality of hydraulic positioners and an inclined plane to position the ultrasound focal point under the control of an operator. An MR imaging system employing a temperature sensitive pulse sequence creates an image of the tissue and the region being heated to allow the operator to adjust the position of the ultrasonic transducer so as to direct ultrasonic energy to the appropriate location.

A magnetic resonance surgery system facilitates performance of surgery with a focussed ultrasound transducer that selectively destroys tissue in a region within a subject. The focussed ultrasound transducer dissipates ultrasonic energy at a focal point within the region of tissue to be destroyed. A number of hydraulic positioners position the focal point under the control of a surgeon. A magnetic resonance imaging system employing a temperature sensitive pulse sequence creates an image of the tissue and the region being heated to allow the surgeon to adjust the position of the ultrasonic transducer so as to direct ultrasonic energy to the appropriate location.

The present invention enables the diamond coating of stationary elongate objects, such as twist drills, with a continuous uniform film without any motion of the twist drill due to the unexpected superb "throwing power" of a reactor disclosed herein. The CVD diamond reactor includes a vacuum chamber, inlet for feed hydrogen/hydrocarbon mixtures, and an outlet, in conventional fashion. The improvement for coating with CVD diamond the entire outer surface of at least a portion of a plurality of stationary elongate objects comprises disposed within said reactor, an elongate metal tube having a plurality of apertures for holding elongate objects disposed radially inwardly and having a cooling pipe in thermal contact with and disposed about the outside of said metal tube; and a filament running within said tube along its lengthwise extent and being in electrical connection with the source of voltage for heating said filament to a temperature adequate to initiate hydrocarbon disassociation, the portions of said elongate object within said tube surrounding said filament being heated thereby.

Transformer cores are made electrically conductive during impulse voltage condition when a certain voltage is attained by a coating of semiconductor material applied to the edges or surface of the core laminations. Under ordinary operating conditions the semiconductor material provides a high resistance path to charges in the core. Upon the occurrence of a high voltage impulse, the semiconductor material rapidly equalizes the charges in the laminations and so avoids the danger of breakdown of the insulating coatings between individual laminations.

A plural substrate CVD apparatus for diamond crystal production utilizes spaced apart vertical, parallel, planar substrate panels with an electrical (direct current, D. C. ) resistance filament heater therebetween. A hydrogen-hydrocarbon gas mixture flows between panels to come into contact with the heater and the panels to cause diamond crystal nucleation and growth on the substrate panels. The apparatus includes means for maintaining the spaced relationship of the heater from the substrate surfaces, comprising a rod member attached to one end of the heater and tensioned by a cable passing over a pulley member and attached to a weight.

Diamond is deposited by chemical vapor deposition on two parallel substrates, by means of a plurality of filaments between said substrates. The substrates and filaments are in vertical configuration and the filaments are linear and spring-tensioned to compensate for thermal expansion and expansion caused by filament carburization. The apparatus includes at least one and preferably two temperature controlling means, usually heat sinks, to maintain substrate temperature in the range of 900. degree. -1000. degree. C. , for optimum rate of diamond deposition.

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.
