    Abstract: A multichamber pressure-increasing device is comprised of a plurality of chambers disposed in series one inside the other, wherein the innermost chamber is configured so as to place objects or samples therein to subject them to ultra-high pressures. An external hydraulic pump pumps fluid into the outermost chamber while a plurality of elemental hydraulic motor pump systems (EHMPS) are mounted in each chamber for increasing the pressure from one chamber to the next one disposed more to the interior of the device through an iterative process, each EHMPS consisting of two cylinder-piston assemblies operatively joined together in such a way that both pistons extend or retract simultaneously within their respective cylinders, the motor part driving the pump part as pressurized fluid admitted into the motor cylinder is subsequently discharged so fluid admitted into the pumping part cylinder is compressed therein and impelled at a higher pressure into the succeeding chamber.

    Abstract: A cutting element include a substrate and a diamond compact including at least two polycrystalline diamond portions separated by at least one metal carbide foil portion. The cutting element is made by placing diamond powder in a reaction container, placing a thin metal layer in the reaction container above or around the diamond powder and binder, placing additional diamond powder in the reaction container above or around the thin metal layer, and placing a pre-sintered substrate containing binder into the reaction container above all diamond powder and thin metal layer components. The assembled reaction container is put into a reactor and is subjected to a high-temperature high-pressure sintering process. The binder in the pre-sintered substrate sweeps through to sinter the first diamond portion, and then reacts with the thin metal layer to form a metal carbide, and then the binder continues to sweep through to sinter the second diamond portion.

    Abstract: Disclosed is a method for hot isostatic pressing a substrate. At first, a metal container is provided. Powder is filled in the metal container before the metal container is located in an oven. The metal container is subjected to isostatic pressing that includes heating and pressing. Thus, the metal container shrinks and presses on the powder evenly and turns the powder into a nugget. The metal container is moved out of the oven and broken to release the nugget. A substrate is cut from the nugget. With the hot isostatic pressing, the substrate exhibits only a few flaws and is large, fine, homogenous and strong so that the substrate is not vulnerable to deformation in a high-pressure environment.

    Abstract: An object of this invention is to provide a fine powder of diamond particles of less than 50 nm with a narrow particle size range. The diamond is single crystalline and characterized with a lot of sharp edges and sharp points. Another object is to provide a method for efficiently producing such fine powder.The method comprises mechanically crushing a raw material of single crystalline diamond particles to prepare starting minute particles of diamond, then imparting hydrophilic quality to the surface of diamond particles. As hydrophilic the diamond particles are dispersed in water to form a slurry, which is set and kept weakly alkaline. The slurry is then subjected to a preliminary grading step, whereby the slurry is removed of a top particle size fraction of the diamond particles that has a D50 size of 60 nm or more. Eliminated of said top particle size fraction, the slurry is then diluted with water to regulate the diamond concentration to 0.1% (by weight) or less. The slurry so conditioned is subjected to a centrifugal force, whereby a coarser particle size fraction of the diamond particles is condensed to a solid cake and removed from the slurry. Effluent slurry is taken out from the centrifugal grading that contains a fraction of the diamond particles having decreased particle sizes.
