A method of producing a ferritic stainless steel strip having reduced intra-face anisotropy as well as excellent r value and anti-ridging characteristics. The method involves subjecting a ferritic stainless steel slab to a hot rolling step including rough rolling having at least one rough rolling pass and a finish rolling having at least one finish rolling pass, followed by a hot-rolled sheet annealing, pickling, cold rolling and finish annealing. At least one of the passes in the rough rolling is conducted with the rolling temperature between about 970.degree. C. to about 1150.degree. C., the friction coefficient between the rolls and the rolled material of about 0.3 or less, and the rolling reduction ratio between about 40 to about 75%.

An automatic IF amplifier band width switching circuit is provided in which band width is switched from broad to narrow in response to either high frequency noise or a predetermined magnitude of interference voltage when the FM detection output is at zero volts. The switching signal may be combined with a hum signal from the tuning knob so that only switching in one direction is possible after tuning is complete.

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:
A resistance variable element is provided, which is capable of performing bipolar operation by a specified mechanism and usable as a memory. The resistance variable element has a laminated structure including an electrode, another electrode, an oxide layer between the electrodes, and an oxide layer in contact with the oxide layer between the oxide layer and the electrode. The oxide layer is switchable from the low-resistance state to the high-resistance state by donating oxygen ions to the oxide layer, and from the high-resistance state to the low-resistance state by accepting oxygen ions from the oxide layer. The oxide layer is switchable from the low-resistance state to the high-resistance state by accepting oxygen ions from the oxide layer, and from the high-resistance state to the low-resistance state by donating oxygen ions to the oxide layer.

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.

The information processing apparatus for project management comprises: a function of displaying on a screen a task area 12 where a symbol 123 representing a document relating to a task constituting a project is displayed; and a function of performing document work according to an operation instruction for the symbol 125 representing the document displayed in the task area 12. The task area 12 has a work area 121 which displays a symbol 123 representing the document, and an output area 122. When a symbol 126 representing a document is moved within the output area 122, the output area 122 displays a symbol representing the document in a task area of another associated task constituting the project.
摘要:
A business justification analysis system for accurately analyzing an opportunity of a business and a risk thereof with a low load. The system basically includes six components, that is, a database for storing a correspondence between opportunity classification items and risk check items, a database for storing the risk check items, a device for selecting the opportunity classification items, a device for extracting the risk check items, a device for inputting a risk check list, and a database for storing risk scores. Information for defining the correspondence between the opportunity classification items of the business and the risk check list items thereof has information about the magnitude of the correspondence. The system further includes a device for applying different weights to the respective check items according to the information when scores of the risk check items are summed.
