    摘要： The present invention relates to a molten steel refining method for refining molten steel, the carbon content of which is not more than 0.1 weight %, by blowing oxygen gas for decarburization at a blowing speed so that a cavity, the depth of which is 150 to 400 mm, can be formed on the surface of molten steel in a straight barrel type vacuum refining apparatus in which a straight barrel type vacuum vessel having no vessel bottom and a ladle are arranged. When necessary, the above decarburizing processing conducted by blowing oxygen gas is combined with: an Al heating process in which Al added into the vacuum vessel is burned by oxygen gas blown into the vacuum vessel at a blowing speed such that the cavity depth can be 50 to 400 mm; a degassing treatment conducted in a high vacuum condition; a desulfurizing treatment in which a desulfurizing agent is blown into the vacuum vessel; or a burner heating treatment in which a combustion improving agent is blown together with oxygen gas, wherein each treatment except for the high vacuum degassing treatment is conducted in a degree of vacuum of 100 to 400 Torr.

    摘要： Methods and apparatus facilitating logging-while-drilling (LWD) using a multi-pole acoustic transmitter source. The multi-pole transmitter source enables measurement of formation velocities, including shear wave velocities through formations that are slower than velocities through local fluids. The methods and apparatus are particularly well suited for LWD and wireline seismic surveys in which both the seismic or acoustic source and receivers are both deployed in a borehole, but may also be used for VSPs (vertical seismic profiling).

    摘要： A computer-readable recording medium storing a data collection program for easily performing a process to collect data from a plurality of core systems at desired timing, and combine and analyze the data and data in a local database. An access request decomposer determines at least one remote database to be accessed, based on an access request accepted by an information management unit, and decomposes the access request into remote access requests each for accessing each of the remote databases. An access unit accesses the remote databases based on the remote access requests created by the access decomposer and extracts data from the remote databases. An aggregation unit aggregates the data extracted by the access unit, and then the aggregation result is displayed.

    摘要： In order to search a file to be searched which includes records having fields allocated to each of a plurality of hierarchical levels and is constructed so that records having a same key character string in a field at a same hierarchical level are arranged in series, an index file is created by obtaining start position information and number information about records having a key character string contained in the hierarchical level of each node on the file to be searched, or a pointer to node management information of a lower hierarchical level, and by recording the information obtained for the nodes of all the hierarchical levels. Further, data is extracted from the file to be searched by using the record start position information, the record number information, and the pointer to the node management information of a lower hierarchical level recorded in the index file.
