Abstract: A control apparatus for a vehicle drive-force transmitting apparatus which defines a first drive-force transmitting path provided with a first clutch and a two-way clutch and a second drive-force transmitting path provided with a continuously variable transmission and a second clutch. The two-way clutch transmits a drive force during a driving state of the vehicle, and cuts off transmission of the drive force during a driven state of the vehicle when the two-way clutch is in its one-way mode. The two-way clutch transmits the drive force during the driving state and during the driven state when the two-way clutch is in its lock mode. An engine torque is increased in a case in which a request for switching the two-way clutch to the one-way mode is made during the driven state in forward running of the vehicle with the two-way clutch being in the lock mode.

Abstract: A most recent value of data fetched from a plant facility is temporarily stored and extracted and then stored in a plant history data table. On another front, a monitoring point for monitoring a plant error is registered in response to an operator request. A monitoring point is used as a key to select and register a main variable point having a strong correlation from the plant history data table. A statistical upper/lower limit function is defined on the basis of time-series plant data of monitoring points and main variable points. By referring to information in a table in which a limit value function is stored, the limit value is periodically matched with the content of a plant-data most-recent-value table. If the most recent value is outside the limit range, deviation information is stored in a determination result table. If a new plant error occurs, an error signal and the content of the determination result table is outputted and displayed.

Abstract: To provide a plant operation data monitoring apparatus capable of monitoring a plant error with high accuracy without requiring a skilled plant operator. A most recent value of data fetched from each sensor in a plant facility is temporarily stored and extracted and then stored in a plant history data table A5. On another front, a monitoring point for monitoring a plant error is registered in response to an operator request. A monitoring point is used as a key to select and register a main variable point having a strong correlation from the plant history data table. A statistical upper/lower limit function is defined on the basis of time-series plant data of monitoring points and main variable points. By referring to information in a table in which a limit value function is stored, the limit value is periodically matched with the content of a plant-data most-recent-value table A3. If the most recent value is outside the limit range, deviation information is stored in a determination result table A13.

Abstract: A plant simulator which makes it possible to set factors which could invite a system accident and to simulate the process of occurrence of a system accident.

Abstract: The present invention relates to holding a call being executed between communication devices in a communication system which has a first function for a holding party of the communication devices to hold the call by transmitting a first request signal to a held party and a second function for the holding party to hold the call by transmitting a second request signal to the held party and receiving a response signal. The holding party transmits the second request signal first and when the response signal is not returned within a given time, transmits the first request signal. A transit device for relaying a call between communication devices, unless detecting the response signal within a given time after relaying the second request signal, transmits the first request signal to the held party, generates the response signal and transmits the generated response signal to the holding party.

Abstract: A facility inspection support apparatus having portable terminal equipment (2) for collecting on the field basis a patrol inspection result at each site of plant facilities, and a processor (1) for receiving the patrol inspection result data collected by the portable terminal equipment and performing a necessary data process. The processor (1) includes a data base (11) for storing in advance a plurality of patrol inspection routes, and discrimination information of patrol inspection items included in the inspection routes, and storing the patrol inspection result data collected by the portable terminal equipment, and facility management processor (15) for deriving the discrimination information of a patrol inspection item designated by the interactive apparatus and a past patrol inspection result data for the designated patrol inspection item, out of the data base, and transferring the discrimination information and the past patrol inspection result data to the portable terminal equipment (2).

Abstract: In a method and a system for diagnosing a thermal power plant system including a thermal power plant, provided with an automatic power plant control system performing PID control, and a direct digital control system utilizing a control model representing the combination of the plant and the automatic power plant control system and controlling the plant to conduct an optimum control, the automatic power plant control system and the direct digital control system conducting control complementarily: a plant diagnostic model formed of a mathematical model representing the combination of the plant, the automatic power plant control system, the control model and the direct digital control system, is provided and used to determine predicted values of the plant variables; difference between the predicted value of each of the plant variables and the actual value of the same plant variable is determined, and stored thereby to provide a time series of the differences which have been successively determined; whiteness ind
