Abstract: A power generation system uses fuel cells (C, S) stacked via separators (31). Cooling plates (33) are provided in the fuel cell stack (S). Passages (34) are formed in each cooling plate (33) for allowing raw-­material-gas-for-reformation (which also serves as stack-cooling-gas) to flow therethrough and the passages (34) are filled with reforming catalyst (61). An external reformer (37) which includes a combustion section (39) and a reforming section (38) is provided outside of the fuel cell stack (5). A stack-cooling-­gas-line (45) is connected to the passages (34) of the cooling plates (33) for introducing the raw-material­gas-for-the-reformation (the stack-cooling-gas) into the passages (33). A line (50) for gas-for-processing is connected to the reforming section (38) of the external reformer (37) for feeding raw-material -gas-for-­processing to the reforming section (38). An anode gas feed line (52) is provided for feeding to the anode (3) the reformed gas which has been reformed through the passages (34) of the cooling plates (33) and the reformed gas which has been reformed by the reforming section (38) of the external reformer (37). An anode exit gas line (53) is provided for feeding the anode exit gas to the combustion section (39) of the external reformer (37). A cathode gas feed line (55) is provided for feeding the combustion exhaust gas discharged from the combustion section (39) to the cathode (2) with air (A).

IPC: H02M3/28
Filed: 1990-05-04
Abstract: Efficient high frequency operation of magnetic devices is achieved by utilizing ferrites that have a low power dissipation hysteresis characteristic and by designing these magnetic devices to operate within an operational range where all applied magnetic forces to the magnetic core have a substantially linear constant permeability response. Within this operational range the hysteresis loop of the selected ferrite material approximates an ellipse with very little area encompassed between the increasing and decreasing B-H locus of the hysteresis loop. The cyclic energy dissipation is significantly reduced as compared to conventional magnetic operations and high frequency operation can be achieved with very high efficiencies.

Abstract: An apparatus that monitors the quality of copies produced by a printing machine. A signal of an image to be reproduced by the printing machine is transmitted to an electronic subsystem. The electronic subsystem (28) converts the signal to a reference bitmap and transmits the reference bitmap to a raster output scanner (30) in the printing machine. The printing machine reproduces the image on a copy sheet. The image reproduced on the copy sheet is scanned by a raster input scanner (32) and a scanned bitmap generated. A comparison is made between the scanned bitmap and the reference bitmap to determine if the image reproduced on the copy sheet is at an acceptable quality level.

Abstract: A distributed network monitor system distributes the network monitoring function among each of the nodes of a multiple network system, such that monitor software resident in each node is responsible for providing status information about that node and its communications links. At predetermined monitoring intervals, a circulating status table (CST) (FIGURE 4) is circulated to all of the on-line nodes, with each node updating the CST with its link and status information. The monitor software includes a servicer task (22), a node monitor task (24), and a packet manager task (26), with intertask data transfers being implemented through a monitor region (28) in memory. In addition to link and node status information, the CST includes information about links that are in an intermittent condition (i.e., links with significantly degraded statistical performance). Intermittent link conditions are determined by a voting procedure in which each node votes on the condition of its links with other nodes, with the results of the votes being distributed in the CST and used by each node to determine those nodes with links in an intermittent condition. For those links without sufficient message traffic to make a clear determination of condition, volunteer nodes send additional link test messages until sufficient statistical information is available.
