A system for operating a plurality of power generation stations. The system comprises: a general control device for monitoring a plurality of power generation stations, each of the stations including at least one electric power generation unit; a plurality of unit control devices, each of which monitoring each of the generation units, the unit control devices producing alarm data; and communication means for exchanging data between the general control device and each of the unit control devices. Only part of the alarm data produced in the unit control devices are displayed at the general control device.

A generation unit general monitor-control system for generally monitoring and controlling electric power generation units (A-3 etc.), the general monitor-control system allocating relations between the electric power generation units and interface devices (11) for monitoring and controlling the generation units. The monitor-control system includes: a unit database (13) storing process data and operation signals; process input-output means (14) for reading out the data from this unit database and outputting the data to the generation units; unit database input-output portion (12) for receiving demands from the interface devices, detecting addresses of the generation units allotted to the interface devices, and referring to data corresponding to the addresses; interface device designating means (22) for designating interface devices; and an interface-device-unit-relation rewriting device (18) for rewriting the allocation relation between the generation unit and the interface devices based upon command from the interface device designating means.

摘要:
An electric power plant general control system for controlling power generating units. A generating unit (GU2) can operate part of the auxiliaries based on an automation command outputted from a unit computer (UC2) having a sequence function portion. The generating unit operates the remaining part of the auxiliaries based on an operation command outputted from an operation board (OB2) without a sequence function portion, the operation board disposed separately from the unit computer. A general automation computer (GAC) is connected with an upper system of the unit computer, and an operator command is inputted from an interactive apparatus (I/F4). The general control system is provided with a mock-up portion (Moc) equivalent to the sequence function portion disposed on the side of the auxiliaries controlled by the automation command outputted from the unit computer. The operation signal from the general automation computer is outputted to the unit computer and the operation board.

A system for controlling a plurality of power generation plants. The system comprises at least three display-input means for displaying process data of the power plants and for inputting signals for operating the power plants based on the displayed process data, and the display-input means are disposed in a central control room. The system also comprises allocation means for allocating at least one of the display-input means to each one of the power generation plants, based on operation phases of the power generation plants. The system also comprises moving means for moving at least one of the display-input means so that a plurality of groups of the display-input means are formed, and the display-input means of a same group be arranged closer to each other than the display-input means of different groups.
摘要:
A method for manufacturing an electronic device is provided. In one example of the method, the method prevents deformation of a resist mask caused by the irradiation of exposure light. The resist mask has a resist as an opaque element, and can afford mask patterns undergoing little change even with an increase in the number of wafers subjected to exposure processing. The resist mask maintains a high dimensional accuracy. A photomask pattern is formed using as an opaque element a resist comprising a base resin and Si incorporated therein or a resist with a metal such as Si incorporated thereby by a silylation process, to improve the resistance to active oxygen. The deformation of a resist opaque pattern in a photomask is prevented. The dimensional accuracy of patterns transferred onto a Si wafer is improved in repeated use of the photomask.
摘要:
An area on a photoresist film which is formed on a substrate surface having a topography, is exposed a plurality of times in such a manner that the image plane of a mask pattern is formed at a plurality of positions which are spaced apart from a reference plane in the substrate in the direction of an optical axis, and then the photoresist film is developed to form a resist pattern. According to the above method, the effective focal depth of the projection aligner used is enhanced, and moreover the reduction of the image contrast at the photoresist film is very small by the plural exposure operations. Accordingly, a fine pattern can be formed accurately on the substrate surface having the topography.
摘要:
There is disclosed a mask which includes a first phase shifter layer and a second phase shifter layer formed on the first phase shifter layer and has a structure capable of easily effecting highly precise control of the phase of exposure light and correction for a defect in the phase shifter layers. There are also disclosed a method of manufacturing the mask and a method of forming by use of the mask a pattern which has a smaller local error in pattern dimension and is free of a defect.
摘要:
A comb-like or dot-like phase shifter pattern is added to a phase shifter used in phase shifting mask technology, which is then exposed onto a wafer. This enables the formation of extremely fine line patterns or space patterns having widths different from each other simultaneously. Further, when two reticles are disposed such that phase shifter patterns disposed therein intersect each other and are exposed consecutively onto a wafer, a fine hole pattern or dot pattern can be formed at a position where the phase shifter patterns intersect each other.
