Title: Roll for continuous casting having breakage resistance and wear resistance
Inventor: YOKOI KIYOSHI
IPC: B21B27/00
Filed: 1987-08-19
Abstract: PURPOSE:To obtain a roll for continuous casting having excellent breakage resistance and wear resistance by forming the specific thickness of nitride layer on roll barrel surface of a stainlessmade roll containing the specific quantity of Cr. CONSTITUTION:The nitride layer having 20-200mum thickness is formed on the steel surface of the stainless steel-made roll containing 7-20% Cr. The nitriding-treated roll is necessary to use the raw material having heat resistance, wear resistance, corrosion resistance, heat cracking resistance and oxidizing resistance for using to roll cladded by welding, centrifugal casting sleeve roll, etc., of the high chromium stainless steel series. The method of nitriding can be used by any method of gas nitriding, gas soft nitriding, salt bath nitriding and ion nitriding. As the nitriding is executed at less than the prescribed temp. in any method, the coated layer is formed on the roll surface without deteriorat ing characteristic of the roll material for continuous casting. The nitride layer is not peeled, because the nitrogen is diffused in the iron and compounds of Fe3N, Fe4N, CrN, etc., are formed. By this method, the roll for continuous casting improving the heat crack resistance and wear resistance is obtd.

Title: Combined power generation plant control device
Inventor: YAMADA TOSHIHIRO
IPC: F02C9/28
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To shorten reaching time to an output target value by preventing reduction in a rising rate of combined power generation system output caused since a gas turbine falls into restriction of an exhaust gas temperature when a load of a combined power generation plant increases. SOLUTION: A bias setting function generator 15 calculates a bias signal Δαto enlarge a rate of change of an output command value Pr on the basis of a bias reference signal predetermined when a load increases up to exhaust gas temperature restricting control. The bias signal Δα obtained by the bias setting function generator 15 is added to a change rate reference value α of a change rate restricting unit 12 by an adder 13c. Therefore, when the load increases up to the exhaust gas temperature restricting control, a rate of change (a rate) of an output command value is enlarged, and reaching time to an output target value PR is shortened.

Title: Radiograph information reading method
Inventor: TSUCHINO HISANORI
IPC: H04N1/40
Filed: 1985-09-18
Abstract: PURPOSE:To obtain correct radiograph information which is corrected in the practical allowable scope by repeating successively the irradiation and the break of the excitation light for the noise light quantity mixed during the scanning and reading of a radiograph converting panel and changed from moment to moment in the forward time point of the sub-scanning and the main scanning. CONSTITUTION:A control circuit 307 and a sample holding circuit A305 synchronize at the time of the break of the laser beam by the synchronizing signal from a synchronizing signal generator 308, determine the voltage inputted to the negative side of a differential amplifier 305 so that the output signal of the differential amplifier 304 becomes zero and the voltage is held up to the time of the next laser beam break. The control circuit 307 and a sample holding circuit B306 synchronize at the time of the irradiation of the laser beam by the synchronizing signal from the synchronizing signal generating device 308, detects the output signal of the differential amplifier 304 and is held so as to interpolate the signal at the time of the laser light break. Out of the obtained picture signal, the signal equivalent to the remaining light quantity is decreased as the voltage inputted to the negative side of the differential amplifier 304 from the sample holding circuit A305. Thus, a picture signal taken out through a logarithm convertor 309 is correct, thereby corresponding to the actual picture.
