Abstract: A game apparatus requiring certain operations of a player within a time limit which displays a first window (W1) for a period of time within a first time limit (TM1), displays a second window (W2) for a period of time within a second time limit (TM2) separate from the first time limit (TM1), and displays at least once the aforementioned first window (W1) during the second time limit (TM2).

Abstract: A power generating plant control system for collectively operating and controlling a power generating plant having a plurality of generating units with unit controllers provided in correspondence with respective generating units belonging to the generating plant and having control logics for applying special purpose operations to control systems of the respective generating units, data servers provided in correspondence with the unit controllers of the respective generating units and for processing and retaining control data and supervisory data of the respective generating units, and a central supervisory control system adapted to input data of the respective data servers through a data bus to carry out supervisory control of the operating states of the respective generating units, and to give start/stop instructions or load operating instructions to the respective generating units.

Abstract: A machine-implemented method of operating a thermal power generating plant having at least one power generating unit comprises (A) determining, in accordance with a given time point t.sub.1 at which the power generating unit is to become capable of load control and assumed time length T.sub.1 for time length of initial load holding TINT, a predicted value t'.sub.PI of a time point t.sub.PI of parallel-in, a predicted value t'.sub.GT of a time point t.sub.GT of a gas turbine start; and a predicted value t'.sub.INC of a time point t.sub.INC of initial load hold completion; and (B) correcting the predicted values t'.sub.PI, t'.sub.GT and t'.sub.INC by adding k(t.sub.1 -t'.sub.INC) to t'.sub.PI, t'.sub.GT and t'.sub.INC, respectively, k being a given value satisfying 0<k.ltoreq.1.
