Title: Fuel injection quantity controlling method
Inventor: HAYAKAWA RIYUUSUKE
IPC: F02D41/40
Filed: 1984-07-09
Abstract: PURPOSE:To check an uncomfortable variation in engine speed, by compensating each compensation variable adjustably so as to set the sum total of compensation variables for a fuel injection quantity to be compensated at each cylinder of an internal-combustion engine down to nearly zero. CONSTITUTION:At a step 302, the sum total S=SIGMAQi of injection quantity correction items Qi for each cylinder is calculated. Next, at a step 303, if an absolute value ¦S¦ is smaller than a threshold value delta, a process comes to an end without doing nothing as it is. If the absolute value is larger than the threshold value delta, it goes forward to the next step 304 in order to add a compensation value to the injection quantity correction item Qi. At steps 304-306, according to positive and negative codes of the said sum total S, a fixed compensation value DELTA is added or subtracted to or from each injection quantity correction item Qi. As a result, the absolute value ¦S¦ of the sum total S of injection quantity correction items Qi is compensated so as to be reduced. Thus, an uncomfortable variation in engine revolution is checked.

Title: Detection system of center point of seal impression
Inventor: TOKUNAGA TAKEHISA
IPC: G06K9/00
Filed: 1984-07-09
Abstract: PURPOSE:To make errors of estimation of a seal impression having voises and omissions smaller than in a conventional one by obtaining a temporary center point of an estimated seal impression, measuring a distance from said point to an outer periphery and correcting the position of the center point with the aid of the distance information. CONSTITUTION:Coordinates of a temporary center point are stored in a memory device 110. In order to obtain a distance Fi from said coordinates to an outer periphery at a 2pii/n angle, an outer periphery detector 120 investigates points in a seal impression memory part along a line in the 2pii/n direction from the side of the temporary center point. The point where a black point exists is judged to be a point on the outer periphery, and its coordinates are stored in the device 110. A distance calculator 130 calculates the distance Fi with the aid of coordinates of the point on the outer periphery obtained by the detector 120 and those of the temporary center point and stores it in the device 110. In accordance with the coordinate value of the temporary center point and radius, a parameter calculator 140 calculates a parameter of the outer periphery of the seal impression with the aid of the Fi and stores it in the device 110. Consequently, when the distance from the temporary center point to the outer periphery of the seal impression is approximated by the prescribed expression, the parammeter for making errors in an actual distance minimum can be obtained.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: MUTO HARUFUMI
IPC: B60W10/10
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent emission from being affected badly by completing learning of an air-fuel ratio feedback correction value early with great accuracy in air-fuel control of an internal combustion engine. SOLUTION: In this control device, an engine load (air intake amount GA) is fixed (as time t to t1 and t2 to t4) when air-fuel ratio learning or purge concentration learning is performed based on the movement of an air-fuel ratio feedback correction factor. Therefore, the engine load does not fluctuate and thus air-fuel ratio of the air-fuel mixture is stabilized even when a driver changes a required torque by adjusting an acceleration opening PDLA. Accordingly, learning can be finished rapidly and very accurately. In addition, while the engine load is fixed, an output torque is controlled according to a required torque by adjusting ignition timing. Therefore, the required torque can be obtained even during learning when the engine load is fixed.

Filed: 1995-06-08
Abstract: PURPOSE: To excellently view display information even at a sample image where the ratio of brightness and darkness is large by providing a light control element at an information display part on an image-forming position. CONSTITUTION: The light control element 7 is provided at the information display part displaying an image made by the sample image and a liquid crystal picture. As the light control element 7, for instance, an EC (electrochromic) element and a liquid crystal element or the like changing transmittance based on a signal given from a light control element driving circuit 11 are used. In the case where visibility is worsened because the inside of a visual field is too bright, the transmissivity of the light contol element 7 is lowered, so that the transmitted light quantity of the background of the information display part and the image made by the liquid crystal picture is lowered.  Therefore, the inside of the visual field is prevented from being too bright while maintaining the brightness of the background of a specified sample image required for observing the sample image, so that the excellent visibility of both the sample image and the information display part is secured.
