Abstract: A separator for an electrochemical fuel cell provides a path for a fuel gas or an oxidative gas to an electrode and functions as a wall of a unit cell of the electrochemical fuel cell. The separator comprises a conductive metal plate, a conductive coating membrane, and a tight coating membrane. The conductive coating membrane coats the conductive metal plate where the separator contacts the electrode. The tight coating membrane coats the conductive metal plate where the conductive coating membrane does not coat the conductive metal plate. A conductivity of the conductive coating membrane is higher than the tight coating membrane, and the tight coating membrane has a tighter adhesion to the conductive metal plate than the conductive coating membrane. The conductive coating membrane comprises carbon, a precious metal, or an alloy of nickel and chromium. The tight coating membrane comprises a close-grained resin. In the electrochemical fuel cell including the separator, the electric resistance between the separator and the electrode can be restrained low, and a rust problem caused by coming-off of the conductive coating membrane from the conductive metal plate can be avoided with high reliability.

Title: A parallel processing decision-feedback equalizer (dfe) with look-ahead processing
Inventor: AZADET KAMERAN
IPC: H04L25/03
Filed: 2000-05-29
Granted: 2004-04-06
Abstract: A method and apparatus are disclosed for increasing the effective processing speed of a parallel decision-feedback equalizer by combining block processing and look-ahead techniques in the selection (multiplexing) stage. The present invention extends a parallel decision-feedback equalization by using look-ahead techniques in the selection stage to precompute the effect of previous blocks on each subsequent block, and to thereby remove the serial output dependency. The parallel decision-feedback equalization includes a multiplexor tree structure that selects an appropriate output value for each block and precomputes the effect of previous blocks on each subsequent block. A  multiplexing delay algorithm on the order of logN is employed to resolve the output dependency and thus speeds up parallel block processing decision-feedback equalizations. The disclosed decision-feedback equalization architecture can be combined with pipelining to completely eliminate the critical path problem. Pipelining reduces the required critical path timing to one multiplexing time. The disclosed multiplexor tree circuitry for the parallel decision-feedback equalizer groups multiplexor blocks into groups of two, referred to as block pairs, and provides at least one multiplexor for each block, i, to select an output value, y i, from among the possible precomputed values. The output of each parallel block depends on the possible precomputed values generated by the look-ahead processors for the block, as well as the actual values that are ultimately selected far each previous block. In order to reduce the delay in obtaining each actual output value, the present invention assumes that each block contains each possible value, and carries the assumption through to all subsequent blocks. Thus, the number of multiplexors required to select from among the possible values grows according to N-logN, where N is the block number.

If a reproduction signal has a data rate of 4 : 4 : 4, the reproduction signal is supplied to a rate conversion circuit (9) for converting the data rate into 4 : 2 : 2 or 4 : 1 : 1. A digital video signal thus converted is supplied to a VTR section (6) through a change-over switch (5). One of the digital video signal from the rate conversion circuit (9) and the reproduction digital video signal from the VTR section (6) is selected by a switch (10). The selected digital video signal is supplied to a D/A conversion circuit (11) and fetched a digital output terminal (12). An analog video signal converted bye the D/A conversion circuit (11) is supplied to a display section (13) consisting of a liquid crystal display unit or the like and built in the device and fetched at an analog output terminal (14).
