Title: Internally modified type fuel cell
Inventor: AKIKUSA JUN
IPC: H01M8/02
Filed: 2003-01-21
Abstract: <P>PROBLEM TO BE SOLVED: To provide an internally modified type fuel cell, capable of appropriately modifying the interior of a separator, without impairing the flow of fuel gas.  <P>SOLUTION: A fuel electrode layer and an air electrode layer are disposed on both surfaces of a solid electrolytic layer, to constitute a power generation cell. The power generation cell and a separator 8, incorporating a gas path for reaction are alternately laminated by a plurality of numbers to constitute a fuel cell; and a porous body 19, in which a hydrocarbon modifying catalyst is held, is disposed in a fuel gas path of the separator 8, so that the hydrocarbon modifying catalyst performs modification reaction before a fuel gas reaches the electrode layer. Since the modifying catalyst is held in an air hole of a porous body 19, it will not move due to the gas supply pressure, so that a dispersed state is always kept inside the porous body, and will not stay at a single location and block the gas flow path. Thus, a good gas flow path is assured at all times for stable power generation.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To allow running in a proper power transmission state matching the circumferences of a road surface and traveling conditions.  <P>SOLUTION: This traveling vehicle comprises a differential device 56 differentiating right and left transmission shafts 57R and 57L transmitting power to right and left travel propelling bodies according to their respective drive loads, a differential limiting device 61 limiting the relative rotational speed difference of the right and left transmission shafts 57R and 57L, and a change mechanism 62 changing the differential limiting area of the differential limiting device. The differential limiting area is increased interlockingly with the swing operation of a machine body. Also, the differential limiting area is increased when the sunk amount of the travel propelling body into a road surface is increased. As the steer angle of the machine body is increased, the differential limiting area is increased. In addition, when a vehicle speed is increased, the differential limiting area is decreased.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a rolling method by which the surface defects of products such as seizing are reduced in the rolling of a metallic sheet such as an aluminum sheet performed by using the roll to which hard chromium plating is applied, and to provide a rolling roll therefor.  <P>SOLUTION: When the hard chromium plating is applied to the outer circumferential surface of the barrel part of a work roll which is used for the finish rolling process of the metallic sheet such as the aluminum sheet, the area ratio of the total area occupied by protrusions which are present in the region of a visual field observed at about 1,000 times magnification in an arbitrary part of the surface of the plating layer to the area of the region of the visual field is made to be ≤5%. Since the local rise of the contact surface pressure is restrained when the area ratio of these nodular protrusions is lowered to this level, the effect of the temperature rise by the frictional heat in the interface between the roll and a rolled stock is reduced, a stable lubricated state is maintained by the reduction of the change of the lubricating film and the generation of the surface defects such as seizing in a product coil is remarkably suppressed.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
