  • Patent number: 7222269
    Abstract: A tabular form screen on which input fields for a parameter and a set value can be added is used as a condition input screen. In a test pattern control part, set values of different parameter groups inputted via the condition input screen are arbitrarily combined, one set value group from each parameter group being selected for one combination, to automatically generate test patterns and parameter files which are information on the set values. An execution control section can control a server and a client terminal of an information processing system to execute performance tests successively only with one input operation based on the generated parameter files.

  • Publication number: 20070012230
    Abstract: A gasification furnace has a gasification chamber for pyrolyzing a raw material in a fluidized medium being fluidized therein to produce a pyrolysis gas and a pyrolysis residue. The gasification furnace also has a combustion chamber for receiving the pyrolysis residue together with the fluidized medium, combusting the pyrolysis residue in the fluidized medium being fluidized therein to heat the fluidized medium, and returning the fluidized medium to the gasification chamber. The gasification furnace includes a partition wall for separating the gasification chamber and the combustion chamber from each other. The partition wall includes a first steel plate having a cooling structure to prevent the pyrolysis gas from flowing between the gasification chamber and the combustion chamber. The gasification furnace allows a general material to be used for components therein and have a long repair period.
