  • Publication number: 20150121021
    Abstract: Write commands for a storage device specify write data with either a first data step size or a second data step size. In the former case, the storage device performs a read-modify-write (RMW) cycle which includes reading data with the second data step size. In the latter case, the storage device executes the command in a single write cycle. A command sorting unit sorts received commands into two groups, first commands and second commands, when storing them in a memory. First commands are write commands whose data boundaries do not match with the second data step size. Second commands include write commands whose data boundaries match with the second data step size. A command issuing unit converts first commands into a second command upon predetermined conditions. The command issuing unit issues the second commands to the storage device, in preference to the first commands.

  • Publication number: 20130294976
    Abstract: An object of the present invention is to provide a fuel processor that can reduce reforming catalyst deterioration caused by thermal deformation of a structure. The fuel processor includes a reformer 8 that is fed with fuel gas 70 to refine hydrogen-rich reformed gas 73 by a reaction of a reforming catalyst 7. A plurality of partition plates 20 for dividing the reforming catalyst 7 are provided in a space filled with the reforming catalyst 7 between an internal cylinder 18 and an external cylinder 19. All the partition plates 20 are cantilevered from the external cylinder, preventing the partition plates 20 from coming into contact with each other in temperature variations. This can reduce deterioration such as crushing or powdering that is caused by a compressive stress of the reforming catalyst 7.

  • Patent number: 8536111
    Abstract: The present invention provides a hydrophilicity-restoring agent for removing inorganic matter from a hydrophilic surface whose hydrophilicity has been reduced by the adhesion of the inorganic matter to thereby restore the hydrophilicity of the hydrophilic surface, and provides a method for restoring the hydrophilicity of a hydrophilic surface using the hydrophilicity-restoring agent. A gel of a hydrophilicity-restoring agent is prepared by mixing a thickener such as polyethylene glycol and xanthan gum with an aqueous solution in which a ligand such as citric acid to form a chelate complex is dissolved. The hydrophilicity of the hydrophilic surface is restored by applying the hydrophilicity-restoring agent to the hydrophilic surface with a reduced hydrophilicity and removing the hydrophilicity-restoring agent after an appropriate lapse of time.
