Title: Air-fuel ratio control device for internal combustion engine
Inventor: OTA TADAKI
IPC: F02D41/22
Filed: 1989-03-29
Abstract: PURPOSE:To prevent the deterioration of operation characteristics at the time of engine start by applying the constitution wherein judgement is made about the failure of an alcohol sensor, an alcohol correction factor is pertinently modified upon the judgment of the occurrence of a failure and a fuel supply amount is determined for later engine startup on the basis of the modified alcohol correction factor. CONSTITUTION:A control means (i) determines a fuel supply amount by correcting a basic fuel supply amount on the basis of an alcohol correction factor and an air-fuel ratio correction factor. Also, when the failure of an alcohol detecting means (d) is judged to have occurred, the alcohol correction factor is fixed at a constant value and then, the alcohol correction factor is modified, depending upon the then air-fuel ratio correction factor. A startup control means (j) determines a fuel supply amount for engine start on the basis of an alcohol correction factor set up at the previous engine operation, when the occurrence of a failure in the detecting means (d) is not discriminated. Upon discriminating the failure of the detecting means (d), a fuel supply amount for later engine startup is determined on the basis of the modified alcohol correction.

Title: Idling rotating speed control device for engine
Inventor: HAMAI YUJI
IPC: F02D41/16
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To stabilize and converge real engine rotating speed to a target idling rotating speed while controlling an air-fuel ratio serving the real air-fuel ratio as the target air-fuel ratio. SOLUTION: A target idling rotating speed is set to a sufficient low rotating speed in which respective engine rotating speed are changed largely by change of an intake air rate and a fuel feed rate. An air rate sucked from a bypass passage 8 for bypassing a throttle valve 6 is regulated by controlling a control valve 9 so as to set a real engine rotating speed to a target idling rotating speed. A rate of fuel injected from a fuel injection valve 7 is regulated so as to set the real air-fuel ratio to the target air-fuel ratio. The fuel feed rate and the intake air rate are corrected nearly simultaneously on the basis of a difference between the real air-fuel ratio and the target air-fuel ratio.

Title: Electrophotographic device

Abstract: PROBLEM TO BE SOLVED: To prevent the useless rotation of a photoreceptor drum in case of emergency stop by detecting the phase of the rotation of the photoreceptor drum and performing the stop sequence of a high-voltage unit. SOLUTION: In the case of forming an image by an image forming part 24, time control is ordinarily performed by using the clock of a timer part 13 by a control part 36. For example, when a copying start switch is inputted, previously fixed operation such as reading an image, feeding transfer paper, forming a latent image on the photoreceptor drum, developing it and transferring a toner image to the transfer paper is successively executed by setting the time as reference. When the transfer paper is wound round a roller or jammed in the middle of a carrying path, the control part 36 outputs an emergency stop signal and switches the control from the time control to phase control.  When the control is switched to the phase control, the control part 36 fetches the phase of a driving motor 10 transmitted from an encoder 12, detects the rotational angle of the photoreceptor drum and performs the control. Namely, the photoreceptor drum is stopped by performing specified sequence by using the phase.
