Abstract: An aluminum alloy bearing includes dispersed Si particles amounting to 1.0 to 10.0 weight % of Si. In such aluminum alloy bearing, relative diffraction intensity of (111) plane of the Si particles is equal to or greater than 0.6.

Abstract: A plain bearing is provided which has an Sn-and-Si-rich layer formed of an Al alloy containing Sn and Si, and a base material which does not contain Sn. The Sn-and-Si-rich layer have the sliding surface having an area ratio of Sn phase grains in a range of 6 to 40% and that of Si phase grains in a range of 5 to 25%.

Abstract: The present invention has been made by the fact that the wettability with lubricant increases when tin grains are broken within a certain range. In an aluminum-based bearing alloy containing from 2 to 20 mass % of tin, the tin grains in a sliding surface have a size not less than 20 ?m2 but not more than 50 ?m2 expressed in region partitioned areas of the tin grains measured in accordance with a region partitioning method.

The Sn-and-Si-rich layer have the sliding surface having an area ratio of Sn phase grains in a range of 6 to 40% and that of Si phase grains in a range of 5 to 25%.

Abstract: The object of the present invention is to provide an electrode for secondary battery according to which the electrode density can be increased and furthermore the electric characteristics can be improved. In the present invention, the sheet material for electrode to be laminated on the surface of a current collector is prepared by mixing and kneading a powdered positive electrode active material or negative electrode active material and a finely powdered conductive material as main components to which a fluorine-containing polymer resin is added, screening the resulting mixture by a sieve to obtain particles of the mixture, adding a liquid lubricant to the particles, preforming the particles to make a sheet-like formed body, and stretching the sheet-like formed body in mono-axial or multi-axial direction.

Abstract: The reformer 100 includes: an evaporating unit 102 that has a source fuel inlet 114 through which hydrocarbon-containing source fuel 202 is introduced, and is capable of evaporating a source fuel 202 introduced through the source fuel inlet 114; a catalyst containing unit 104 that is provided in the evaporating unit 102 and stores a reforming catalyst 108, which is capable of inducing a reaction for reforming the source fuel 202 into a reformed fuel having higher hydrogen amount; and a hydrogen outlet 118 that is provided on the catalyst containing unit 104 so as to communicate with the catalyst containing unit 104.
