Title: Method for controlling air-fuel ratio of engine
Inventor: KIYARORU MARII CHIYOO
IPC: F02D41/14
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To obtain a management air-fuel ratio control system which transfers between a closed loop theoretical A/F mode and an open loop lean A/F action mode by periodically changing from an open loop fuel control mode to a closed loop fuel control mode to correct the value of an open loop correction rate. SOLUTION: A heating exhaust oxygen sensor(HEGO) 36 is used. The HEGO sensor 36 detects oxygen included in exhaust produced by an engine 18 and sends its typical signal to an electronic engine controller(EEC) 20 via a conductive body 40. A program memorized in a ROM 58 executes an air-fuel strategy. A plurality of speed/load type conditions enter a management air-fuel mode. An air/fuel ratio A/F is changed from a theory to a desired lean A/F under an open loop lean mode permitting condition. While the open loop lean mode is worked, a system periodically returns to a closed loop theoretical mode to update an open loop correction rate used in the open loop lean mode.

Abstract: PURPOSE:To define a bias magnetic field as a fluctuating magnetic field and furthermore to prevent the distortions of a reproduction signal and the reduction of magnetization M, by setting a part of a conduction lead connected to an MR element at a position opposite and approximate to said MR element. CONSTITUTION:One of conduction leads 24 and 25 connected to an MR element 23 is bent at a place near the connection part of the element 23, and said counter and approximate plate 27 is set in parallel to the element 23 via the element 23 and an insulated film 26. The other end of each conduction lead is connected to a constant voltage drive source. In this case, an increase or decrease bias magnetic field HB2 is applied to emphasize a signal magnetic field HS in accordance with the direction of a drive current flowed to the part 27 as long as both a bias magnetic field HB1 and the HS are set in the same direction or opposite to each other. Thus the action point of the element 23 is shifted on a rho-H characteristic curve 28. In this respect, a current is flowed via the leads 24 and 25 according to the direction of the field HS in case the minute signal magnetic field HS is applied to the element 23. Then the field HB2 is impressed. Thus a reproduction output signal 32 is which only 2HB2 is enlarged by the curve 28 is obtained. In such a case, the shift range of an action point can be regarded as a linear form. Thus no distortion of reproduction is produced.

Filed: 1993-03-24
Abstract: PURPOSE:To make it possible to perform synchronous operation smoothly regardless of whether a workpiece is a rigid body or not when the common workpiece is driven with two main shafts provided in a machine tool. CONSTITUTION:Whether the deviation between the positions of both main shafts exceeds the value set with a deviation setting device 32 or not is monitored with a comparator 31 even in operation under torque balance control. When the value exceeds the preset value, it is judged that a work 2 cannot be regarded as a rigid body. A torque adjusting signal contact 5 is opened and a position adjusting signal contact 8 is closed through a correcting-value selecting circuit 33. The speed command value of a second motor 23 is corrected with a position adjusting signal. Thus, the torque balance control can be smoothly switched to control operation for smoothly matching the positions of the main shafts even if the machine tool is operating.
