    • A learning control method for an electronic engine control system in which a variable concerning the adhesion of injected fuel onto a wall surface of an intake manifold, the evaporation of adhered fuel or the runaway of fuel to a cylinder is determined on the basis of a detection value of the operating state of an engine in accordance with a predetermined relational expression and the quantity of fuel injection is controlled on the basis of the determined value of the variable so that a target air/fuel ratio is realized, comprises the steps of determining the degree of deviation of an air/fuel ratio from the target value after the engine has been turned from a steady operating state into a transient operating state, determining a range in which the detection value of the engine operating state as the base of determination of the variable has changed upon occurrence of a fuel injection quantity control error which causes the deviation of the air/fuel ratio from the target value, and correcting a corresponding relationship between the engine operating state and the variable in the determined range of change on the basis of at least the degree of deviation of the air/fuel ratio from the target value by use of a rule-based inference.

    • A method and an apparatus for control of engine fuel injection are characterized by detecting the state of the acceleration of the engine and also judging whether or not the engine is in a specific acceleration state, by, when the engine is judged to be in a specific state of acceleration, using such a value as a crank shaft angle obtained in advance in order to predict the air mass flow rate of the air flowing into a specific cylinder having undergone a fuel injection, by using the predicted air mass flow rate or the crank shaft angle to determine a proper asynchronous fuel injection quantity for the above-mentioned acceleration state for the specific cylinder, and then by performing an asynchronous injection. In this way, it is possible to calculate the shortage of fuel occurring with the synchronous injection even at the early stage of acceleration by using various variables so as to determine a proper supplemental fuel supply quantity (asynchronous injection quantity) for achieving a desired air fuel ratio in various drive modes.

    • An electronic seal stamp and an electronic sheet are used. The electronic seal stamp has a stamp surface, and has a storing function and output function for electronic information. The electronic sheet is of a sheet shape, has a surface capable of being impressed, and has a storing function and input function for electronic information. When the electronic seal stamp is impressed on the electronic sheet, a seal image on the stamp surface of the electronic seal stamp is transferred to the surface of the electronic sheet. At the same time, the electronic information stored in the storing function of the electronic seal stamp is transferred to the storing function of the electronic sheet, through the output function of the electronic seal stamp and the input function of the electronic sheet. Thus, an electronic seal stamp system, in which both impression of the stamp surface and electronic sealing are possible, is realized.
