Title: Hydrogen storing method
Inventor: HIBINO KOETSU
IPC: F17C11/00
Filed: 1999-08-18
Abstract: PROBLEM TO BE SOLVED: To improve absorbing density in hydrogen gas storage under pressurization by mixing carbon dioxide, nitrogen or soft hydrocarbon with hydrogen to be stored. SOLUTION: The relationship between the storing pressure and the storing density (V/V0) at 25 deg.C in the case of adding carbon dioxide (CO2) to hydrogen by 10% is shown in a diagram. In the diagram, the storing density in the case of simply storing only hydrogen in a container without mixing with CO2 is also shown as a comparative example. It is found from the diagram that the storing density V/V0 is improved by about 20% by mixing CO2 with hydrogen. This is considered to result from that CO2 has high affinity to hydrogen molecules, and the moving speed of hydrogen is lowered by intermolecular force between hydrogen and CO2 so as to improve the storing density. As gas to be mixed with hydrogen, nitrogen is taken as well as CO2. In the case where nitrogen is mixed with hydrogen, the storing density is improved by about 5% at pressure of 20 Mpa (storage pressure).

Title: Structured document retrieving device
Inventor: ANDO TOSHIAKI
IPC: G06F17/27
Filed: 1993-08-25
Abstract: PURPOSE:To evade the duplicate control of information and also to retrieve the information in a short time with regard to a structured document retrieving device which selects the desired one of many documents stored in a storage. CONSTITUTION:The logical structure, the attribute and the contents of a structured document are extracted by a logical structure extracting part 7 and stored only in a document information storing part 8. Therefore it is not required to perform the troublesome duplicate control that always keeps the matching property of information, etc. In an information retrieving state, a logical structure deciding part 9 decides whether the document has a logical structure equal to that described in a retrieving expression. Then the direct accesses are applied to the component elements (author name, etc.), i.e., the final retrieving target only about the document having the same logical structure. Thus the information can be retrieved in a short time compared with a conventional retrieving device that finally acquires the component elements of the final retrieving target after checking a document successively from its beginning part.
