  • Patent number: 7125534
    Abstract: Single-walled carbon nanotubes have been synthesized by the catalytic decomposition of both carbon monoxide and ethylene over a supported metal catalyst known to produce larger multi-walled nanotubes. Under certain conditions, there is no termination of nanotube growth, and production appears to be limited only by the diffusion of reactant gas through the product nanotube mat that covers the catalyst. The present invention concerns a catalyst-substrate system which promotes the growth of nanotubes that are predominantly single-walled tubes in a specific size range, rather than the large irregular-sized multi-walled carbon fibrils that are known to grow from supported catalysts.

  • Patent number: 7125308
    Abstract: Activation of printed or dispensed carbon nanotube (CNT) film using a particle-blasting technique, also referred to as sandblasting or bead blasting. The process works by sending particles of material at high enough velocity such that when the particles hit the surface, some of the material at the surface is removed. The surface of the printed CNT film is slowly eroded away by the particles from the particle gun. The CNT fibers may be embedded in several layers of the printed layer, so they may not be removed easily.

  • Patent number: 7121340
    Abstract: An apparatus for reducing the post-detonation pressure of a perforating gun, the apparatus including a perforating gun carrying at least one explosive charge, wherein when the explosive charge is detonated the explosive charge produces a pressurized detonation gas, and a mechanism for reducing the pressure of the detonation gas proximate the perforating gun. The detonation gas pressure is desirably reduced in a time frame sufficient to create a dynamic underbalance condition to facilitate a surge flow of fluid from a reservoir into a wellbore. The pressure reduction mechanism may include singularly or in combination a heat sink to reduce the temperature of the detonation gas, a reactant to recombine with the reactant gas and reduce the molar density of the detonation gas, and a physical compression mechanism to utilize the waste energy of the detonation gas to create work, simultaneously reducing the temperature of the gas and the molar density of the detonation gas.

  • Patent number: 7122079
    Abstract: The present invention includes a composition for a silicon-containing material used as an etch mask for underlying layers. More specifically, the silicon-containing material may be used as an etch mask for a patterned imprinted layer comprising protrusions and recessions. To that end, in one embodiment of the present invention, the composition includes a hydroxyl-functional silicone component, a cross-linking component, a catalyst component, and a solvent. This composition allows the silicon-containing material to selectively etch the protrusions and the segments of the patterned imprinting layer in superimposition therewith, while minimizing the etching of the segments in superposition with the recessions, and therefore allowing an in-situ hardened mask to be created by the silicon-containing material, with the hardened mask and the patterned imprinting layer forming a substantially planarized profile.

  • Patent number: 7120826
    Abstract: A method, system and computer program product for performing an expansion of a disk array. Upon the failure of a disk in the disk array, the failed disk may be rebuilt stripe by stripe in the spare units distributed among other disks in the disk array. Upon repairing or replacing the failed disk with a spare disk, the repaired or spare disk may be rebuilt stripe by stripe using the data from the spare units. Upon receiving a write request to a stripe unit that has been rebuilt in the repaired or spare disk during expansion, the data of the request may be written in the stripe unit requested. Further, the data written may be mirrored, i.e., copied and stored, in the spare unit corresponding to the stripe unit requested. By mirroring the data to the corresponding spare unit, tracking each stripe that was updated during expansion may be eliminated.

  • Patent number: 7115864
    Abstract: This invention relates generally to a single-wall carbon nanotube (SWNT) purification process and more particularly to a purification process that comprises heating the SWNT-containing felt under oxidizing conditions to remove the amorphous carbon deposits and other contaminating materials. In a preferred mode of this purification procedure, the felt is heated in an aqueous solution of an inorganic oxidant, such as nitric acid, a mixture of hydrogen peroxide and sulfuric acid, or a potassium permanganate. Preferably, SWNT-containing felts are refluxed in an aqueous solution of an oxidizing acid at a concentration high enough to etch away amorphous carbon deposits within a practical time frame, but not so high that the single-wall carbon nanotube material will be etched to a significant degree. When material having a high proportion of SWNT is purified, the preparation produced will be enriched in single-wall nanotubes, so that the SWNT are substantially free of other material.

  • Patent number: 7113048
    Abstract: A pseudo Set/Reset latch circuit is configured with modified NOR or NAND gates wherein one of the series pull-up devices or pull-down devices is removed. A minimum of three pseudo Set/Reset latches may be coupled as a ring oscillator generating an output and a non-skewed complementary output. Additionally, feed-forward inverting stages may be coupled in parallel with inverting paths in the ring oscillator primary path to further increase the frequency range of the ring oscillator. The pseudo Set/Reset latch circuits and the feed-forward inverting stages may be configured with voltage controlled devices that alter the delay of the stages as a means for varying the frequency of the ring oscillator either by varying the current drive of the circuitry driving the output of the latch stages or by varying the conductance of devices coupling between the latch stages. Feedforward inverting stages may comprise pseudo latches or inverter gates.

  • Patent number: 7106540
    Abstract: A method, computer program product and hard disk drive for restricting a rate of spin-up/spin-down cycles for a spindle motor in a hard disk drive. The firmware in the hard disk drive determines a maximum rate of spin-up/spin-down cycles the spindle motor is designed to handle over a designated period of time based on the number of spin-up/spin-down cycles the spindle motor is designed to handle over its expected lifetime. The firmware disables the automatic standby mode of operation if a calculated rate of spin-up/spin-down cycles during the designated period of time is greater than the maximum rate of spin-up/spin-down cycles the spindle motor is designed to handle over the designated period of time. By disabling the automatic standby mode of operation, the rate of spin-up/spin-down cycles will be reduced as the spindle motor will not incur a spin-up/spin-down cycle until the automatic standby mode of operation is enabled.

  • Patent number: 7104111
    Abstract: The present invention provides for variable-range hydrogen sensors and methods for making same. Such variable-range hydrogen sensors comprise a series of fabricated Pd—Ag (palladium-silver) nanowires—each wire of the series having a different Ag to Pd ratio—with nanobreakjunctions in them and wherein the nanowires have predefined dimensions and orientation. When the nanowires are exposed to H2, their lattace swells when the H2 concentration reaches a threshold value (unique to that particular ratio of Pd to Ag). This causes the nanobreakjunctions to close leading to a 6–8 orders of magnitude decrease in the resistance along the length of the wire and providing a sensing mechanism for a range of hydrogen concentrations.

  • Patent number: 7107487
    Abstract: A method, system and computer program product for implementing a fault tolerant sleep mode of operation. The system state information may be stored in a volatile memory and in a non-volatile storage unit prior to entering the sleep mode of operation. If a memory corruption event, e.g., power outage, brownout, power surge, occurs during the sleep mode of operation, then, upon receiving an invocation to resume to a normal mode of operation, the system state information stored in the non-volatile storage unit may be reloaded into the volatile memory. By reloading the system state information stored in the non-volatile storage into the volatile memory, the computer system may resume to a normal mode of operation from a sleep mode of operation without any corruption or loss of data.
