Title: Method for operating sintering machine
Inventor: HAMADA MASANARI
IPC: C22B1/20
Filed: 1992-06-11
Abstract: PURPOSE:To stabilize the calcination point of a sintering machine with high control accuracy and to improve productivity by correcting the calcination points detected at air discharge temps. with the SOx value in exhaust gases and regulating a pallet speed by the corrected calcination points at the time of sintering particulate iron ore. CONSTITUTION:A raw material mixture 4 composed of the particulate iron ore, returns and coke, etc., is supplied from a hopper 2 onto an endless grate 5 of a DL sintering machine to form a packed bed 6. The raw material packed bed 10 is sintered by igniting coke in an ignition furnace 7 and sucking air from wind boxes 8 in the lower part of the grate 5. The measured values of the air discharge temps. by thermocouples 10 in the respective wind boxes 8 are inputted to a calcination distance computing device 20 which in turn detects the calcination points. After the average calcination distance in the transverse direction of the grate 5 is computed, the measured value of the SOx in the exhaust air by a gas analyzer 19 is inputted to the computing device 20 which in turns corrects the calcination distance and inputs the corrected calcination distance to a calcination point controlling and computing device 21. This computing device calculates the pallet speed for obtaining the target calcination distance and applies the pallet speed as the measured value of a pallet speed detecting and device 23. The calcination point is thus controlled with the high accuracy.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: KAKIZAKI SHIGEAKI
IPC: F02D41/04
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To provide an air-fuel ratio control device for an internal combustion engine capable of suppressing the change of the torque generated by the engine caused by the step-like change of the learning value and satisfactorily maintaining operability. SOLUTION: The learning value PHOS is retrieved in S22, and the primary annealing process (weighted mean process) is applied to the learning value PHOS to obtain the learning value PHOS(new) in S23. The primary seasoning process is implemented until the deviation between the learning value PHOS retrieved in S22 and the leaning value PHOS(new) becomes below the prescribed value (S24-S26), and the fuel injection quantity is corrected with the learning value PHOS(new) . When the deviation becomes below the prescribed value, the primary annealing process is completed, and the fuel injection quantity is corrected with the learning value PHOS retrieved in S22. Even if the learning value PHOS is switched, no step-like change is generated on the fuel injection quantity, and the change of the torque generated by an engine, i.e., the deterioration of operability, can be prevented.

Filed: 1990-07-06
Abstract: PURPOSE:To form a printed picture in response to the request from an operator and, at the same time, to improve the service lives of a developing agent and photosensitive body by providing a means through which the operator can change the spot diameter of laser light. CONSTITUTION:A microprocessor 1 receives the information designated from a console panel 8 and sends drive information for driving an actuator 6 to a drive 4 after processing the drive information on the basis of the designated information so as to drive the actuator 6 by an instructed amount. The actuator 6 is coupled with an arm 11 the other end of which holds a plane parallel glass plate 12. Accordingly, when the actuator 6 is moved by a prescribed amount, the spot diameter of laser light 19 on a photosensitive body 18 changes, because the image forming position shifts due to the thickness of the glass plate 12. Therefore, the operator of this picture forming device can obtain the optimum line width and can compensate the variation of line width caused by the changes in the body 18 and a developing agent with the lapse of time. In addition, the service lives of the photosensitive body 18 and developing agent can be extended.

IPC: F02D41/34
Filed: 1993-07-21
Abstract: PURPOSE:To provide a device capable of performing reduction in costs and torque control with high accuracy in a generated torque control device for car engine. CONSTITUTION:In performing control of torque generated in an engine, it has been noted that the width of injection pulse applied to an injector 15 is roughly proportional to torque value generated in the engine. After a given target torque is converted by a target injection pulse width conversion unit 13b, the difference between the injection pulse width from an injection pulse width control unit 13c and a target injection pulse width converted by the target injection pulse width conversion unit 13d is determined by a pulse width calculating unit 13d. Thus, the opening of a sub-throttle 7 is controlled by a motor driving control unit 13a so that the difference of the injection pulse width from the target injection pulse width, which is determined by the pulse width calculating unit 13d, becomes smaller.
