  • Publication number: 20060222853
    Abstract: In one embodiment, composite constructions of the invention are in the form of a plurality of coated fibers bundled together to produce a fibrous composite construction in the form of a rod. Each fiber has a core formed from a hard phase material, that is surrounded by a shell formed from a binder phase material. In another embodiment of the invention, monolithic sheets of the hard phase material and the binder phase material are stacked and arranged to produce a swirled composite in the form of a rod. In still another embodiment of the invention, sheets formed from coated fibers are arranged to produce a swirled composite. Inserts for use in such drilling applications as roller cone rock bits and percussion hammer bits, and shear cutters for use in such drilling applications as drag bits, that are manufactured using conventional methods from these composite constructions exhibit increased fracture toughness due to the continuous binder phase around the hard phase of the composites.

  • Patent number: 6423779
    Abstract: A method includes providing a starting material having a Young's modulus (202). Second, from a plurality of possible modifiers, a modifier is identified and selected that has a Young's modulus comparable to or greater than that of the starting material and that, when blended with the starting material, creates a blend with a stable morphology (204). Third, the scratch resistance of the starting material is increased by blending the modifier with the starting material to form a blend (206). Alternatively, the scratch resistance of the stating material is maintained while the toughness of the starting material is increased by blending the modifier with the starting material to form a blend.

  • Patent number: 6090725
    Abstract: A method for preventing bubble defects in borophosphosilicate glass (BPSG) film is provided. A wafer for depositing borophosphosilicate glass (BPSG) film is loaded in deposition chamber. After the wafer is properly positioned, the wafer is heated to a predetermined temperature. A process gas is introduced from the gas distribution system to the deposition chamber. A selected pressure of the deposition chamber is set and maintained throughout deposition process. After deposition of the BPSG film, the wafer is loaded out the chamber. Subsequently, helium gas is introduced to purge the liquid injection valve and delivery path. After pumping out the purge gas, the another wafer is then loaded in the chamber for depositing BPSG film.
