Title: Idling speed controller for engine
Inventor: OTA YUJI
IPC: F02D41/08
Filed: 1990-11-28
Abstract: PURPOSE:To keep off any slippage of a leaning value due to pulsation attending on on-off drive of a bypass passage by heightening the extent of on-off driving frequency in a control valve do as not to resonate with natural frequency in an intake system at time of operating the leaning valve of an air-fuel ratio. CONSTITUTION:An on-off valve 13 opens or closes a bypass passage 12, bypassing a throttle valve 9 and feeding an engine with auxiliary air, after being controlled by an engine control unit 30. In addition, this engine control unit 30 operates the learning value of an air-fuel ratio on the basis of a deviation between the actual air-fuel ratio and the desired one so as to make the air-fuel ratio of mixture to be fed to the engine converge on the desired air-fuel ratio when the specified condition is materialized. At time of operating the learning value, the engine control unit 30 makes the on-off driving frequency of the on-off valve 13 higher than resonance frequency resonating with natural frequency in an intake system. With this constitution, such a fear that the learning value is shifted by pulsation with the on-off drive of the passage 12 is preventable.

Filed: 1990-11-28
Abstract: PURPOSE:To perform serial communication and correct servo control free from interruption with a single CPU by stopping the serial communication after power supply to a motor and restarting the serial communication at the time of detecting a servo alarm. CONSTITUTION:This method consists of a servo controller 1, a servo amplifier 5, and a servo motor 6.

Abstract: PURPOSE:To realize element isolation by a shallow trench, and improve element reliability, by forming a diffusion layer under an insulating film for isolation, isolating a part of the diffusion layer by a trench, and burying insulator in the trench. CONSTITUTION:A buried diffusion layer 13 is formed under an insulating film 12 for isolation: impurity profile of a collector region 15 of an element actuation region is formed by control independent of the buried diffusion layer 13; the buried diffusion layer 13 and the collector region 15 are formed so as to be electrically connected. That is, since a shallow buried layer 13 is formed under the insulating film 12 for isolation, the depth of an element isolation trench 14 is satisfied to be 1-2mum, and manufacturing is facilitated. Impurity profile of the collector region 15 is formed by control independent of the buried diffusion layer 13, and is not directly affected by the buried diffusion layer 13, so that the profile is not affected by thermal diffusion and autodoping from the buried diffusion layer. Hence the irregularity of collector impurity concentration distribution is controlled and precision-control is enabled.
