  • CAD information management system and CAD information management method
    Patent number: 6816861
    Abstract: Databases store therein CAD drawings which different manufacturers have. Other databases store therein equipment specifications. All the databases are connected to a user terminal via a communication line. Data stored-destination address information is inputted to designate information on the CAD drawing or the equipment specification, from a user terminal, and one of the databases is searched based on the data stored-destination address information, thereby selecting the information on the CAD drawing or the equipment specification is selected from one of the databases, corresponding to the data-stored destination address information, based on the search.

  • Steam turbine power plant
    Patent number: 6742336
    Abstract: A steam turbine power plant comprises a high-pressure turbine to be driven by steam generated by a steam generator, a first reheater for separating moisture from steam discharged from the high-pressure turbine and heating the steam, an intermediate-pressure turbine to be driven by the steam heated by the first reheater, a second reheater for heating exhaust steam discharged from the intermediate-pressure turbine, and a low-pressure turbine to be driven by the steam heated by the second reheater. The intermediate-pressure turbine discharges dry steam.
