    摘要: A carbon film of the present invention has an elongated needle shape whose radius decreases toward a tip. The shape is, preferably, a shape in which a field concentration coefficient β in the Fowler-Nordheim equation is expressed by h/r where r denotes the radius in an arbitrary position and h denotes height from the arbitrary position to the tip.

    摘要: The quasi-absolute encoder module determines absolute position within one mechanical rotation. The encoder module includes a three channel position encoder and detection circuitry that includes a read-only memory (ROM). There are three channels: A, B, and I. Channels A and B have four periods and channel B is offset from channel A by 90.degree. in phase. Channel I has a unique sequence. The address generated by sampling this unique sequence corresponds to an address in ROM. The address indicates the position of the rotating shaft on which the code wheel is attached.

    摘要: The present invention relates to a catalytic conversion process for improving the product distribution, characterized in that a feedstock oil of good quality is contacted with a hot regenerated catalyst having a lower activity in a reactor to carry out a cracking reaction, the reaction product is separated from the spent catalyst to be regenerated, then the reaction product is fed into a separation system, and the spent catalyst to be regenerated is stripped, regenerated and recycled in the process. The isobutene content in the liquefied petroleum gas (LPG) produced by the process is increased by a factor of more than 30%, and the olefin content in the gasoline composition may be increased to more than 30 wt. %. The product distribution is optimized, and the yields of dry gas and coke are decreased, so as to sufficiently utilize the petroleum resources.

    摘要: A neutron generator includes carbon nanotubes that function as the anode and provide deuterium storage. The ionization source includes a layer of carbon nanotubes that provides a pulse of deuterium ions through field-induced desorption and ionization of deuterium atoms on the surface or retained in the bore of the nanotubes. A high-yield (>1010 n/s) neutron generation is achieved by employing a field desorption ion source and applying an electric field of 10-40 V/nm. Such high fields may be achieved with carbon nanotubes having high aspect ratios with field enhancement factors on the order of 1000. By operating the ion source in a background pressure of deuterium or hydrogen, the gas adsorption on the nanotubes may be regenerated after each pulse.

    摘要: Aspects relate to methods, devices and manufacturing relating to routing networks including a method for routing data units. The data units are individually routable through a routing network. A reservation request data unit is received over the routing network and from a sender. At least one speculative data unit associated with the reservation request data unit from the sender is received. The at least one speculative data unit is dropped in response to the at least one speculative data unit being blocked within the routing network. The sender is provided, over the routing network, a negative acknowledgement data unit that indicates the dropping of the at least one speculative data unit. The sender is provided a grant data unit indicating a start time. After the start time, at least one non-speculative data unit corresponding to the reservation request from the sender is received.

    摘要: A continuous serpentine cooling circuit forming a progression of radial passages (44, 45, 46, 47A, 48A) between pressure and suction side walls (52, 54) in a MID region of a turbine airfoil (24). The circuit progresses first axially, then tangentially, ending in a last radial passage (48A) adjacent to the suction side (54) and not adjacent to the pressure side (52). The passages of the axial progression (44, 45, 46) may be adjacent to both the pressure and suction side walls of the airfoil. The next to last radial passage (47A) may be adjacent to the pressure side wall and not adjacent to the suction side wall. The last two radial passages (47A, 48A) may be longer along the pressure and suction side walls respectively than they are in a width direction, providing increased direct cooling surface area on the interiors of these hot walls.
