Title: Thermal power plant controller
Inventor: SHIMIZU SATORU
IPC: G05D23/19
Filed: 1996-03-18
Abstract: PROBLEM TO BE SOLVED: To suppress and minimize the change of steam temperature by providing a parameter computing means or the like for calculating an integrated feature quantity representing the feature of the steam temperature from a plurality of feature quantities of the steam temperature and forming a new dynamic preceding control parameter by a parameter correction coefficient estimating means based on the integrated feature quantity. SOLUTION: A feature quantity sampling function 403 samples the quantities of features of steam temperature waveforms from the time series data of the respective steam temperature deviations of a steam temperature deviation sampling function 401. An integrated feature quantity computing function 408 obtains the integrated feature quantity of the steam temperature waveforms. If the feature quantity does not satisfy a control target value, a parameter correction coefficient estimating function 405 will obtain a correction coefficient for correcting a dynamic preceding control parameter. An adjusting rule storing function 406 stores a rule required for obtaining the correction coefficient. A parameter computing function 407 multiplies a current dynamic preceding control parameter by the correction coefficient so as to form a new dynamic preceding control parameter.

Abstract: PURPOSE: To prevent deterioration of the electrode material by adopting such a production process having the steps of forming a first resist film of a predetermined pattern, forming an inorganic film over the entire surface, forming a second resist film and then effecting an etching on the inorganic film.  
     CONSTITUTION: An electrode material 3 is formed on a semiconductor substrate 1 coated with an insulating film 2 and a first photoresist film 6 is formed on the electrode material 3 and then patterned in such a manner that the photorresist film 6 remains on the area where the opening is to be formed. Then, the entire surface is coated by, for example, a silicon oxide film 4 which is then coated with a second photoresist film 5 such that the opening of the second photoresist film 5 is positioned in the area where the first resist film 6 remains. Then, the oxide film 4 is etched under the mask of the second photoresist film 5 to form an opening. Then, the first and the second photoresist films 6, 5 are removed by an immersion in a solvent. By so doing, the direct contact between the electrode material 3 and the oxide film 4 is avoided to prevent undesirable phenomenon such as degradation or dissolving of the electrode material 3 at the opening, remaining of the oxide film and so forth.

Filed: 1989-04-12
Abstract: PURPOSE:To prevent the property deterioration and the breakdown strength lowering by hot carriers by connecting a plurality of MIS transistors in series, and driving them as if they are the MIS transistors of one figure. CONSTITUTION:This consists of a plurality of gate electrodes 5 and 6, which are provided on a substrate 1 through an insulating film, and are formed apart from one another, and are connected electrically, and the second conductivity type source 2 and drain 3 regions, which are located at both ends of the a plurality of gate electrodes 5 and 6 and are located within the single crystal substrate 1. Hereby, in case that first and second transistors are in OFF condition, the voltage applied between the source 2 and the drain 3 is shared between each transistor, thus the breakdown strength greater than the breakdown strength feasible with one transistor can be realized. Furthermore, the voltage applied to the second transistor becomes smaller by the amounts of voltage applied to the first transistor than the voltages applied to the source 2 and the drain 3, and by that amounts the deterioration by hot carriers can be made decreased.
