Abstract: PURPOSE:To improve controllability of air-fuel ratio by high accurately correcting a difference of detecting responsiveness in an air-fuel ratio sensor caused by a direction of changing the air-fuel ratio, in the case of feedback-controlling the air-fuel ratio by converting an output value of the air-fuel ratio sensor into a value of showing the air-fuel ratio. CONSTITUTION:An air-fuel ratio sensor 16 senses concentration of a specific component in exhaust changed by air-fuel ratio of a mixture, sucked into an internal combustion engine 1, thus to change an output value. In a response correcting means, correction corresponding to a difference of detecting responsiveness of the air-fuel ratio sensor 16 by a direction of changing the air-fuel ratio is applied relating to the output value of the air-fuel ratio sensor 16. Further in an output converting means, the corrected output value is converted into a value of showing the air-fuel ratio. In an air-fuel ratio control means, the air-fuel ratio is feedback controlled to the target air-fuel ratio based on the value of showing the air-fuel ratio. Now in the response correcting mean, the output value is corrected by a preset correction value based on change ratio of the output value in the air-fuel ratio sensor and a predetermined correction constant in accordance with a direction of changing the air-fuel ratio.

IPC: H04M3/26
Filed: 1990-02-28
Abstract: PURPOSE:To test a subscriber line by a home device by providing an exchange with an audible tone sending device and a bit error measuring instrument. CONSTITUTION:A telephone set 4 sends a connection request to an exchange 20. A CPU 12 forms a speech path. After automatic incoming to a digital audible tone sending device 8, a subscriber terminal circuit 6 instructs a network terminating device 2 to turn back the used speech path channel by the command of the CPU 12. The terminating device 2 turns back it as it is to form a turning- back loop of 64kbps including a bit error measuring instrument 10. This instrument 10 sends a dummy random digital bit signal to a subscriber line 1 and compares it with the signal turned back by the network terminating device 2 with each bit as the unit to calculate the error rate of the speech path loop. The CPU 12 commands release of turning-back after a prescribed time, and the network terminating device 2 is returned to the normal mode. When the bit error rate is >=10<-3>, the instrument 10 sends an audible tone of 10<3>Hz and a maintenance man on the home side finds the wrong state of the laid subscriber line.

Title: Motor controlling circuit and motor system using this circuit
Inventor: HAYASHI MICHIHIKO
IPC: H02P29/40
Filed: 1993-03-11
Abstract: PURPOSE:To suppress an influence on a motor by a ripple contained in an output signal by installing a current controller which, according to a motor control command signal, changes the current flowing into a constant current device which determines the current flowing into a differential amplifier which amplifies an input signal. CONSTITUTION:A base of a transistor for controlling current 30 is connected to a base of a transistor 14a, 14b of a current mirror 14 to make an amount of current flowing into the transistor 30 proportional to the current flowing into the current mirror 14 or an input signal T for controlling a torque of the motor. Therefore, when the input signal T is small, an amount of current flowing into the transistor 30 becomes small and as a result, an amount of current flowing into a transistor 18a becomes small and a gain of an error amplifier 10 is small. Eventually, an amplification factor to a ripple component contained in the input signal T becomes small and thereby a bad influence on a motor can be held down. When there is no input signal T, the amplifier 10 doen not work and the erroneous output does not appear.
