Abstract: To provide a pulverized coal burner capable of reducing the NOx concentration at the time of a low load, a pulverized coal burner includes a secondary air nozzle (103) and a tertiary air nozzle (104) concentrically positioned about the outer periphery of a fuel nozzle (102) carrying a pulverized coal with a primary air (135), and two swirling flow generators (113, 114) are included at least one of these nozzles (104) with a positional relation parallel to a flow of air. One of the swirling flow of the two swirling flow generators (113, 114) can be set strongly. And, under a condition of low air flow rate, air can be supplied from one swirling flow generator (112) alone. 
     Since the swirling strength of the combustion air can be increased, the concentration of NOx produced by the combustion of the pulverized coal can be reduced. Since the swirling strength at the time of the low load can be increased, the NOx concentration can be reduced by keeping the pulverized coal flame stable.

Abstract: An integrated circuit assembly that prevents silver migration by providing conductive rims around oxidizable silver contacts that contact a substrate. Typically the silver contacts are supported by respective metal pads on the substrate with a contact potential existing at each contact-pad junction. In many applications an electrical circuit transmits electrical signals via the contacts to produce potential differences between the contacts and create electrical fields at their surfaces. The conductive rims have a work function that is sufficiently small to reduce the electric fields and contact potentials so as to inhibit the ionization of the oxidized contacts' surfaces and prevent silver migration across the metal pads and the substrate.

Abstract: A self-replenishing hydrodynamic bearing unit comprises a shaft and housing defining an opening for receiving the shaft for relative unidirectional rotation. A plurality of reservoirs contain a lubricating fluid. A hydrodynamic bearing region lies between the plurality of reservoirs for providing a rotational journal for relative rotation between the shaft and the housing. At least one of the shaft and the housing defines a continuous pattern of herringbone or Vee-shaped pumping grooves or passages which communicate between the plurality of reservoirs for pumping the lubricating fluid during relative rotation. The groove pumping creates a pressurized hydrodynamic bearing lubricant film at the bearing region with each groove generating localized unidirectional directional flow of lubricating liquid between the reservoirs along a predetermined axial direction of rotation, wherein some passages create axial flow in a forward direction and the others create axial flow in a reverse direction. The passages are arranged so that a total of the axial flows from all of the pumping passages is essentially zero.

Abstract: A method and apparatus for implementing a fully associative cache directory (78) that stores X cache tags and responds to N read cache tags simultaneously in a single cache directory access to provide a corresponding cache block index for each of the N read cache tags. The cache directory includes a mini-directory (500) and a main directory (520). The mini-directory stores M cache tags and corresponding block indexes, wherein M is equal to at least N. The mini-directory is fully associative and simultaneously compares each of the M stored cache tags against each of the N read cache tags. The main directory stores the X cache tags and provides corresponding block indexes. The main directory is fully associative and compares P read cache tags against each of the X cache tags simultaneously, P being less than N. The N read cache tags are initially compared against the mini-directory to provide a block index for each of the N read cache tags that hits in the mini-directory. Only those read cache tags that miss in the mini-directory are compared against the main directory.

Abstract: Motion video is represented by digital signals. The digital signals can be compressed by coding to reduce bitrate and thus save time and expense in transmitting and reproducing the video. The present invention is a system and method for reducing the amount of information required to satisfactorily reproduce video signals by distinguishing more pertinent portions of the video from less pertinent portions. In particular, edges are detected based on amplitude variations in the luminance characteristic of the picture elements. Sharp edges are deemed to be "focused". The portion of the video frame between the focused edges is deemed to be focused, as well. A template is created corresponding to the focused portion. A signal corresponding to the outline of the template is combined with the original frame signal to create a segmented frame signal. When motion detection information is available, a motion-based template may be created and intersected with the focus template. A signal corresponding to the outline of the intersected template may be transmitted with the frame signal as the segmented frame signal.
