A method and architecture are provided for SOC (System on a Chip) devices for RAID processing, which is commonly referred as RAID-on-a-Chip (ROC). The architecture utilizes a shared memory structure as interconnect mechanism among hardware components, CPUs and software entities. The shared memory structure provides a common scratchpad buffer space for holding data that is processed by the various entities, provides interconnection for process/engine communications, and provides a queue for message passing using a common communication method that is agnostic to whether the engines are implemented in hardware or software. A plurality of hardware engines are supported as masters of the shared memory. The architectures provide superior throughput performance, flexibility in software/hardware co-design, scalability of both functionality and performance, and support a very simple abstracted parallel programming model for parallel processing.

A method of forming an improved Schottky diode structure as part of an integrated circuit fabrication process that includes the introduction of a selectable concentration of dopant into the surface of an epitaxial layer so as to form a barrier-modifying surface dopant layer. The epitaxial layer forms the cathode of the Schottky diode and a metal-silicide layer on the surface of the epitaxial layer forms the diode junction. The surface dopant layer positioned between the cathode and the diode junction is designed to raise or lower the barrier height between those two regions either to reduce the threshold turn-on potential of the diode, or to reduce the reverse leakage current of the transistor. The particular dopant conductivity used to form the surface dopant layer is dependent upon the conductivity of the epitaxial layer and the type of metal used to form the metal-silicide junction.

A floating, semi-submerged, tethered device that supports a horizontal axis turbine and power generation equipment for extracting kinetic energy from a tidal stream or ocean current. A submerged body (1) is supported by surface piercing struts (2) of small water plane area (FIG. 6). The device is tethered to the seabed by a spread of mooring lines (12) that are deployed both into and away from the direction of the tidal current. A horizontal axis turbine (4) harnesses energy from the water flow and drives a generator housed within the body. A horizontal strut hydrofoil (24) corrects the trim of the device when subject to varying loads from the mooring system and can also be used to dampen pitch motion. Rudder flaps in the struts (25) can be used to counteract roll motion. Power is exported from the device to the seabed by an umbilical (17). A thrusters (22) can be used to constrain the rotation of the device about its mooring system to prevent excessive twist building up between the mooring lines and the power export umbilical.

Fine-grained (average grain size 1 nm to 1,000 nm) metallic coatings optionally containing solid particulates dispersed therein are disclosed. The fine-grained metallic materials are significantly harder and stronger than conventional coatings of the same chemical composition due to Hall-Petch strengthening and have low linear coefficients of thermal expansion (CTEs). The invention provides means for matching the CTE of the fine-grained metallic coating to the one of the substrate by adjusting the composition of the alloy and/or by varying the chemistry and volume fraction of particulates embedded in the coating. The fine-grained metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling. The low CTEs and the ability to match the CTEs of the fine-grained metallic coatings with the CTEs of the substrate minimize dimensional changes during thermal cycling and prevent premature failure.

Since VF and IR characteristics of a Schottky barrier diode are in a trade-off relationship, there has heretofore been a problem that an increase in a leak current is unavoidable in order to realize a low VF. Moreover, there has been a known structure which suppresses the leak current in such a manner that a depletion layer is spread by providing P+ regions and a pinch-off effect is utilized. However, in reality, it is difficult to completely pinch off the depletion layer. P+ type regions are provided, and a low VF Schottky metal layer is allowed to come into contact with the P+ type regions and depletion regions therearound. A low IR Schottky metal layer is allowed to come into contact with a surface of a N type substrate between the depletion regions. When a forward bias is applied, a current flows through the metal layer of low VF characteristic. When a reverse bias is applied, a current path narrowed by the depletion regions is formed only in the metal layer portion of low IR characteristic. Thus, a low VF and low IR Schottky barrier diode can be realized.

The number of pairs of third and fourth lead-out portions for third and fourth internal electrodes in the second capacitor portion is less than the number of pairs of first and second lead-out portions for first and second internal electrodes in the first capacitor portion, so that the first capacitor portion contributes to decreasing ESL while the second capacitor portion contributes to increasing ESR.

A method of producing networks of low melting metal oxides such as crystalline gallium oxide comprised of one-dimensional nanostructures. Because of the unique arrangement of wires, these crystalline networks defined as “nanowebs”, “nanowire networks”, and/or “two-dimensional nanowires”. Nanowebs contain wire densities on the order of 10⁹/cm². A possible mechanism for the fast self-assembly of crystalline metal oxide nanowires involves multiple nucleation and coalescence via oxidation-reduction reactions at the molecular level. The preferential growth of nanowires parallel to the substrate enables them to coalesce into regular polygonal networks. The individual segments of the polygonal network consist of both nanowires and nanotubules of β-gallium oxide. The synthesis of highly crystalline noncatalytic low melting metals such as β-gallium oxide tubes, nanowires, and nanopaintbrushes is accomplished using molten gallium and microwave plasma containing a mixture of monoatomic oxygen and hydrogen. Gallium oxide nanowires were 20-100 nm thick and tens to hundreds of microns long. Transmission electron microscopy (TEM) revealed the nanowires to be highly crystalline and devoid of any structural defects. Results showed that multiple nucleation and growth of gallium oxide nanostructures can occur directly out of molten gallium exposed to appropriate composition of hydrogen and oxygen in the gas phase. The method of producing nanowebs is extendible to other low melting metals and their oxides such as for example: zinc oxide, tin oxide, aluminum oxide, bismuth oxide, and titanium dioxide.

A hydraulic antivibration device is provided that is capable of suppressing generation of strange sounds while ensuring a low dynamic spring characteristic upon inputting of relatively small amplitude vibration and a high damping characteristic upon inputting of relatively large amplitude vibration. To that end, upon inputting of relatively large amplitude vibration, displacement-regulating ribs of one of sandwiching members serve to regulate displacement of an elastic partition membrane pinched by the sandwiching members thus obtaining a high damping characteristic. The displacement-regulating ribs consist of three pieces extending radially and rectilinearly, so that the area of openings of the sandwiching members is made wide enough to ensure more a low dynamic spring characteristic. Displacement-regulating protrusions of the elastic partition membrane are disposed to correspond to the displacement-regulating ribs thereby ensuring to suppress the generation of strange sounds.
