Title: Control method of air-fuel ratio and study in internal-combustion engine
Inventor: OKAWA NOBUNAO
IPC: F02D41/00
Filed: 1984-09-14
Abstract: PURPOSE:To improve controllability, by enabling a value of individual study item, study corrected on the basis of an air-fuel ratio feedback correction coefficient, to be corrected at each study to the center side of a p0redetermined correction limit range by a value corresponding to an averaged change from a reference value of these study items. CONSTITUTION:When an engine is in operation, a control circuit 56 controls an injection quantity of fuel from a fuel injection valve 30 on the basis of a product obtained by a feedback correction coefficient, determined for aligning air-fuel ratio to the theoretical air-ratio study value corrected for holding a value of the coefficient within a predetermined range. Here the above described study value has plural study values studied in each of the plural operational ranges, further each study value has a common study item in the whole operational range and an individual study item in each operational range. And the control circuit, both subtracting a deviation, between an average value in the whole individual study item after it is corrected by said correction coefficient and the reference value, from each individual study item and adding the deviation to the common study item, sets a correction limit range of the common study item wider than that of the individual study item.

IPC: C21D9/56
Filed: 1988-08-02
Abstract: PURPOSE:To enhance thermal efficiency and to suppress the oxidation of a work by sucking and boosting the waste combustion gas generated in a direct firing type heating zone, burning the gas in a catalyst layer and introducing this gas into a convection type preheating zone. CONSTITUTION:The traveling band-shaped steel sheet 4 is heated by the exhaust gas formed in the direct fire type heating zone 3 and thereafter, the succeeding steel sheet 4 introduced into a radiation type preheating zone 5 is preheated. Further, the exhaust gas is sucked and boosted by a boosting fan 6 on the inlet side of the radiation type preheating zone 5 and is introduced into a combustion section.

Title: Signal conditioning device
Inventor: BAASU ARAN KIYANFUIIRUDO
IPC: H04N5/52
Filed: 1991-05-02
Abstract: PURPOSE: To prevent the generation of rapid change in a control signal. CONSTITUTION: A counter 20 counts the pulses of a clock signal. The count value of the counter 20 is used as an output signal. The output signal is compared with an input signal by a comparator 12, and a control signal for deciding whether or not the counter 20 should operate counting increase or counting decrease is generated. A comparator 14 compares a signal obtained by adding the input signal with the number of offsets with the output signal. Signals from the compressors 12 and 14 are supplied to an OR gate 18. A signal from the OR gate 18 operates/non-operates the counter 20. In a period in which the input signal has relatively constant amplitude, the counter 20 does not operate any counting increase or counting decrease only by one unit value.
