摘要： PROBLEM TO BE SOLVED: To efficiently and inexpensively separate and recover carbon dioxide discharged from a large-scale carbon dioxide generating source by a compact apparatus. SOLUTION: In a method for separating and recovering the carbon dioxide from the by-produced gas or the like generated at an iron manufacturing factory by a chemical absorption process, the low-quality exhaust heat generated at the iron manufacturing factory is used or applied for a process for separating the carbon dioxide by heating a chemical absorption solution after absorption of the carbon dioxide from the gas by the chemical absorption solution.

摘要： PURPOSE:To obtain a device which is small, light and also exhibits excellent loading and unloading efficiency by charging switching means when demagnetization is carried out so that an electric current may flow in the second exciting coil in the opposite direction to the case of attracting, thereby controlling the current which flows in the first and second exciting coils at the prescribed timing after controlling the first and second rectifiers. CONSTITUTION:An electromagnet equipped with the first and second exciting coils 4a and 4b which connect to the first and second rectifiers 2 and 3, switching means 11 and 12, a controlling means 10, and the like and provided. In the case of attracting, the controlling means 10 controls the rectifiers 2 and 3 and the switching means 11 and 12 and permits a current to flow in the exciting coils 4a and 4b so that a magnetic flux generated by the first and second exciting coils 4a and 4b may exert on the same direction. In the case of demagnetization, the controlling means 10 charges the switching means 11 and 12 so that the current flows in the second exciting coils 4b, that is, in the opposite direction to the case of attracting and the first and second rectifiers 2 and 3 are controlled on the basis of electric current values which are detected with detecting means 7a and 7b and then the current flowing in the first and second exciting coils 4a and 4b are controlled at the prescribed timing.

摘要： PURPOSE:To control an interval between steel pipes accurately by operating a transport distance in a chasing control period by means of an interval between individual steel pipes at the entrance side of a group of detectors and at the exit side of them so as to instruct a speed change to a group of rolls in the front by means of the transport distance and the speed. CONSTITUTION:Due to a set error of the skew angle theta of a skew turning roll 2 and a difference in slipping between a steel pipe and the skew turning roll 2 resulting from a difference in materials of skew turning roll and an abrasion of the skew turning rolls 2 and others, the transport speeds of steel pipes differ depending upon positions, but the steel pipes of the same length have repeatability in the same position, therefore by taking advantage of its feature an interval between a preceding steel pipe 10 and a following steel pipe 11 is controlled. Each passing speed of preceding steel pipe rear end and following steel pipe tip end between each detector is sought by plural detectors 22-28 detecting steel pipe ends and a chasing control starting point of the following steel pipe is operated by means of the sought speed distribution of the preceding steel pipe rear end and the following steel pipe tip end and others and thereby the rotating speed of the skew turning roll transporting the following steel pipe is controlled to change the interval between steel pipes into the expected value accurately.

摘要： PURPOSE:To reduce the software cost by eliminating the duplication of functions of controllers in all fields like the steel production fecilities, etc., and at the same time to improve the maintenance properties with minimization of the software quantity. CONSTITUTION:A process controller 10, an electric controller 20, and an instrumentation controller 30 are integrated together by an EIC fusing controller 100 which shares a C function 110, an E function 120, and an I function 130 through the software. Then a common date base 140 is added to exchange the information among those functions together with a process input/output device 101 which integrates the input/output operations to the processes in place of the conventional communication equipments 24 and 34, and a man- machine interface 103 which integrates the offer of information to an operator and the input of instructions given from the operator.

摘要： PURPOSE:To make it possible to recognize the planar shape of a steel plate during conveyance on a rolling apparatus by recognizing the position in the conveying direction corresponding to the position data in the direction of each width to be measured. CONSTITUTION:A measuring gage 1, a width and length gage 5, a straightener 9, a plate width gage 10 and the like are provided on a conveying line 15 in this apparatus for a thick steel plates. The position data at both end parts in the width direction of the thick steel plate are repeatedly detected at a specified position at a substantially constant period. The measured position is recognized based on the timing when the tip of the thick steel plate is detected and the conveying speed of the thick steel plate. The shape of the thick steel plate in the conveying direction is recognized based on the distribution of the detected position data of each measuring position.

摘要： PURPOSE:To execute the automatic recognition of welding phenomena by kinds thereof so that an optimum welding state is maintained by providing a waveform analyzer which outputs a welding kind signal indicating the present welding state from the characteristic signal outputted from a calculator and a membership function. CONSTITUTION:The waveform analyzer is previously stored with the patterns of the signal S1 by each of the respective welding kinds, more specifically, the membership function. The analyzer recognizes the welding kind of the present welding state from the signal S1 and the membership functions stored therein when said signal is inputted thereto from a subtractor 46. The analyzer outputs the signal S2 indicating the recognized welding kind. The signal S2 is inputted to a voltage commander 51 by which said signal is compared with the desired welding kind. The voltage commander outputs the voltage command signal S3 for eliminating a difference if there is the difference between said signal and the desired welding kind. The voltage command signal S3 is put into a control section 49 which changes a firing control signal S4 and changes the output voltage of a voltage regulator 41. The correction to execute the welding with the desired welding phenomena is thereby executed.
