An apparatus for manufacturing a single silicon crystal comprises a quartz crucible accomodated into a graphite crucible, a partition member partitioning molten silicon material in the quartz crucible into a single silicon growing portion on the inner side and a material melting portion on the outer side, a heater for maintaining the molten silicon material in the single silicon growing portion at a temperature appropriate for growing the single silicon crystal and for supplying heat for melting the raw materials fed into the material melting portion, and small holes made in the partition member. The partition member is made of an opaque quartz glass. The material melting portion is replenished with the raw materials and single silicon crystal is pulled from the single silicon growing portion. Molton silicon material moves from the material melting portion into the single silicon growing portion through small holes made in the partition member.

In the cabling work aiding system, the RFID reader reads the RFID attached to at least one of the terminal, its terminal block, and cable member. A cabling work terminal device is connected to the RFID reader. The device is comprised of: a data base that records a template connection diagram containing the terminal-side RFID region constituted by RFID data as to the terminal and a cable-side RFID region constituted by RFID data as to the cable member; a relating part that relates the RFID read by the RFID reader to the terminal-side RIFD region and the cable-side RIFD region defined in the template connection diagram; a terminal-cable member correspondence table preparing part that prepares a correspondence table for leading correspondence between the RFID data as to the terminal and RFID data as to cable member from correspondence between the terminal-side RIFD region and the cable-side RFID related by the RFID read by the RFID reader.

A business information management system includes a data connection relationship information storage section storing connection relationships of data items forming a business information database, a data connection accuracy information storage section that stores data connection accuracy between data item pairs having a connection relationship, and a data change section that changes data in the business information database by inputting data thereto. A change affected data extraction section extracts change affected data items by tracing first data items having a connection relationship with an originally changed data item and second data items having a connection relationship with the first data items until there is no connection relationship, a change effect probability calculation section calculates change effect probability of the change affected data based on data connection accuracy, and a change affected data display section displays the change effect probability on a display unit.
摘要:
When an RFID is attached to an object to assist testing operations, the following problems are encountered; (1) the RFID of write type tends to cause a failure and is troublesome due to the necessity of rewrite each time the situation is changed, (2) the incorporation of the reader function in a terminal block increases the cost, and (3) the known techniques are targeted for only the connecting operation and are not adapted for a sequence test that takes the most expense in time and effort. The operations are aided by using an RFID reader and a terminal having the function for accessing a database of circuit information, RFID information, and test procedure information.

A computer readable storage medium encoded with a project assessment program for assessing a project including a plurality of processes when executed by a computer computing forecasts of the project based on a set of information. At least one scheme by a user input is selected from a group of schemes including an estimation of mutual-correlation of estimated value pattern. Process planning information, up-to-date actual process information and forecast model information of each process included in the project is retrieved. The forecast model information of each process of the project is defined as probability distribution variations of a plurality of parameters of the processes, wherein the probability distribution variations are quantitative values of the project. Estimated values of variations in at least two parameters of the processes using the process planning information, the up-to-date actual process information and the forecast model information are computed.

A wall-thickness thinning rate at a not-measured position is estimated using information having a small number of measured points. Simulation of behavior of fluid flowing inside a pipe line is performed based on wall-thickness data of pips and three-dimensional layout data of the pipe line including the pips using a computer, and simulated wall-thickness thinned data of the pipes composing the pipe line is calculated from change of the simulated behavior of fluid.
