摘要： A drill bit assembly comprises a bit body intermediate a shank and a working face. The shank is adapted for connection to a drill string. The drill string comprising a fluid passage at least partially disposed within the body. A hammer assembly is movably disposed within the fluid passage along it central axis, the hammer assembly comprises a proximal end stabilized by a centralized upper bearing and a distal end stabilized by centralized a lower bearing. The distal end protrudes out of the working face and the hammer assembly comprises a carrier between the upper and lower bearings. Wherein, under normal drilling operations the carrier is adapted to resist a fluid pressure within the fluid passageway such that the fluid pressure will further extend the distal end of the hammer assembly from the working face by pushing on the carrier.

摘要： An integrated circuit apparatus with heat removal has an electrical interconnection network. The electrical interconnection network has a plurality of electrically and thermally conductive vias in electrical communication with terminals of at least one semiconductor device. An electrically insulating heat spreader is chemically bonded to each of the vias at an upper layer of the electrical interconnection network. At the upper layer the vias are electrically isolated from each other. In some embodiments the electrically insulating heat spreader is a polycrystalline diamond body with a metallized undersurface. The metallized undersurface may be etched away between vias.
