Abstract: PURPOSE:To restrain air and fuel mixture from getting leaner and prevent the hegitation by quantitatively compensating the fuel supply to increase when an engine is accelerated and gradually reducing the addition of compensated fuel supply quantity when a throttle valve is opened at the angle more than the specified value. CONSTITUTION:Operation data of an internal combustion engine, including valve of the opening of a throttle valve is detected by a means A. When the operation state detected by the means A is regarded as the normal state, the quantity of fuel supplied in the normal run is set by a means B. Additionally, a means C datects the air-fuel ratio of mixture and a means D judges an acceleration state. A means E sets the compensated feedback quantity which is the compensated reference quantity of fuel supplied to have the air-fuel ratio proximate to the target valve in the specified operation state except the acceleration state. On the other hand, a means F compensates the reference quantity of fuel supplied to increase in the acceleration mode and a means G gradually reduces the compensated addition of the fuel quantity when the throttle valve opens at the angle more than the specified valve. Then the specified quantity of fuel is supplied via a means H.

Filed: 1991-06-21
Abstract: PURPOSE:To prevent the generation of a noise in a specific frequency decided by both a sampling frequency and an input voltage by operating a D/A conversion by a single voltage source and a single feedback capacitor. CONSTITUTION:Switches 32 and 26 are connected in parallel with an input capacitor 20 by clock pulses phi2 and phi2A, and a voltage is inputted to the input of an arithmetic amplifier circuit 25. Then, a voltage obtained by adding a voltage -VR to an input voltage VIN is stored in an integration capacitor 26. Also, when a switch 34 is turned ON in the timing of a clock pulse phi2B, the terminal (a) of a feedback capacitor 30 is connected with the voltage -VR, so that a voltage VR can be added to the input voltage VIN charged in the input capacitor 20, and this voltage can be stored in the integration capacitor 26. Thus, two kinds of voltages obtained by D/A converting the output of a delay circuit 28 by the single voltage -VR and the single feedback capacitor 30, can be outputted, and subtracted from the input voltage VIN.

Abstract: PROBLEM TO BE SOLVED: To prevent paper clogging in a discharge port and the drop of a recording medium from a paper discharge tray by measuring the height of the recording medium loaded on the paper discharge tray by a height measuring means and giving an alarm when the recording medium reaches a predetermined height to stop the image forming operation. SOLUTION: A distance between a distance measuring sensor 62 and a recording paper 42 on a paper discharge tray 56 is measured when the recording paper 42 is not discharged from a discharge port 54 to obtain the height of the recording paper 42 loaded on the paper discharge tray 56 and judge whether the height of the recording paper 42 is the predetermined height or not. Here, the predetermined height means the height of the recording paper 42 which is loaded up to a position which is slightly lower than the discharge port 54. When it is judged that the height thereof reaches the predetermined height, a stopper generates an alarm sound to attract user's attention.  If the user does not cope with this alarm at all, the image forming operation is stopped in an emergency because the recording paper 42 overflows from the paper discharge tray 56 or the recording paper 42 is clogged in the discharge port 54.
