Title: Hydrogen permeable membrane and hydrogen extractor
Inventor: AOYAMA SATOSHI
IPC: C01B3/56
Filed: 2002-04-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a technique for preventing the strength of a hydrogen permeable membrane from becoming insufficient at the time of permeation of hydrogen through the membrane.  <P>SOLUTION: A hydrogen extractor 10 is equipped with a hydrogen permeable membrane 20, reinforcing members 34 and 36 and flow channel members 30 and 32. A flow channel of a modified gas containing hydrogen is formed between the hydrogen permeable membrane 20 and the flow channel member 30. A flow channel of a purge gas mixed with hydrogen extracted from the modified gas by the hydrogen permeable membrane 20 is formed between the hydrogen permeable membrane 20 and the flow channel member 32. The hydrogen permeable membrane 20 is equipped with a plurality of catalyst layers 24 and the extraction operation of hydrogen is mainly performed in a region where the catalyst layer 24 is formed. Since a degree of the solid solution of a hydrogen atom is suppressed in the hydrogen permeable membrane 20, membrane strength is ensured sufficiently.  <P>COPYRIGHT: (C)2004,JPO

Title: Method for evaluating error-correcting code for data block of finite size
Inventor: YEDIDIA JONATHAN S
IPC: H04L1/24
Filed: 2002-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for evaluating an error-correcting code for a data block of a finite size. SOLUTION: The error-correcting code is defined by a parity check matrix in which columns represent variable bits and rows represent parity bit, and represented as a bipartite graph having two parts. Until the number of nodes in the bipartite graph becomes less than a prescribed threshold, a single node in the bipartite graph is repeatedly renormalized. During repeated renormalization, a specified variable node is selected as a target node and a distance between the target node and the other node in the bipartite graph is measured. Next, when there is at least one leaf variable node, a leaf variable node farthest from that target node is renormalized. Otherwise, a leaf check node farthest from the target node is renormalized or variable node, having the fewst directly connected check codes farthest from the target node is normalized.
