Title: Air-fuel ratio controller for internal combustion engine
Inventor: NAGAI TOSHINARI
IPC: F02D41/00
Filed: 1985-09-10
Abstract: PURPOSE:To prevent the deterioration in fuel consumption, drivability, emission, etc. by starting the air-fuel ratio feedback control by a downstream side O2 sensor from the center value of the memorized air-fuel ratio control quantity. CONSTITUTION:The first and the second air-fuel ratio sensors are installed on the upstream side and the downstream side of a catalytic converter. When an air-fuel ratio feedback condition judging means judges that an engine satisfies the prescribed conditions, an air-fuel ratio control quantity calculating means calculates there air-fuel ratio control quantity according to the output of the second air-fuel ratio sensor on the downstream side. Further, when a learning condition judging means judges that the engine satisfies the learning conditions, a learning means memorizes the center value of the air-fuel ratio control quantity, and an air-fuel ratio adjusting means adjusts the air-fuel ratio according to the output of the first air-fuel ratio sensor and the air-fuel ratio control quantity. At the time point when the feedback conditions are satisfied, the air-fuel ratio control quantity is set as the memorized center value. Thus, the large deflection of the air-fuel ratio control level can be prevented.

Title: Object detecting method
Inventor: NAKAMURA YUKIHIKO
IPC: G01B21/00
Filed: 1993-07-19
Abstract: PURPOSE:To recognize an object from the variation of frequency by driving a motor equipped with a three-phase pulse encoder, rotating a contactor at a predetermined speed, monitoring the pulse from the encoder and stopping the motor when the contactor comes into contact with an object. CONSTITUTION:A CPU 14 instructs a motor driver 15 to feed a predetermined current to a motor 10 at a detecting section 9. The motor 10 rotates a contactor at a constant speed and, at the same time, a three-phase pulse encoder 11 generates a three-phase pulse signal corresponding to the r.p.m. of the motor, which is fed through the interface 16 at a control section 12 to the CPU 14 for each rotational direction. The CPU 14 processes the input signal and delivers the results through an interface 17. When the contactor comes into contact with an object, rotation of the motor 10 is stopped to interrupt generation of pulse thus allowing detection of the object. When the number of pulses are counted with reference to an original point, i.e., the signal of phase C, contact angle of the contactor can be determined. This method allows decision of the chipping of drill cutter, the size and the type of object, in addition to the presence thereof.

Title: Electrostatic latent image developing device
Inventor: KITAMURA TAKAHIKO
IPC: G03G15/09
Filed: 1982-11-15
Abstract: PURPOSE:To prevent temperature rise of a magnetic developing agent and insufficient detection of toner density, by constituting a scooping up means with a vane wheel and sleeve, whose part is united with the vane wheel in one body and arranging a magnet in the sleeve so that the magnet is fixed in a device space. CONSTITUTION:A scooping up means 5 is arranged to the location of a scooping up roller 21 and the outlet end section of a sensor duct 24 is arranged closely to the sleeve 53 of the scooping up means 5. Therefore, magnetic developing agent D flowing through the sensor duct 24 is discharged toward the peripheral surface of the sleeve 53 and immediately scooped up and carried. At this time, the magnetic force of a magnet acts to attract the magnetic developing agent D from the sensor duct 24. The heat generated in the sleeve 53 section is insignificant when compared with a case where the scooping up means itself is composed only of a scooping up roller. In this way the magnetic toner smoothly flow through the sensor duct 24 and detection of toner density can be performed accurately. Moreover, scooping up of the magnetic developing agent D can be performed effectively by vane wheels 51 and 52.
