    摘要： A single cylinder engine is equipped with a carburetor having an electrically controlled air bleed control valve. A microcomputer of an electronic controller calculates a target opening timing and a target opening time period of the air bleed control valve. The microcomputer, receiving a rotation pulse from a rotation sensor indicative of an engine rotational position, opens the air bleed control valve at the calculated target opening timing and for the calculated target opening period so that the air bleed control valve controls an amount of air-bleeding which in turn controls an air-fuel ratio of mixture supplied to the engine.

    摘要： An electronic musical instrument with plural pitch data generating functions includes a keyboard, a plurality of tone generating units, a pitch designating unit, a plural pitch data generating unit, and a musical tone generating unit. The keyboard has a plurality of keys. The tone generating units generate at least two tone signals in response to operation of a key among the plural keys. The pitch designating unit designates a pitch of a musical tone to be produced. The plural pitch data generating unit generates at least two pitch data based on the pitch and in accordance with different scale characteristics. The musical tone generating unit generates at least two musical tone signals based on at least two pitch data respectively, so that at least two musical tone signals have the different scale characteristics.

    摘要： Various types of information utilized for performance of an electronic musical instrument are stored in first and second memories. The information stored in the first memory represents parameters, as a preset data set, which determine a characteristic of a musical tone to be produced. The information stored in the second memory is auxiliary data representing information other than the parameters such as performance messages. The auxiliary data used in combination with the preset data set are stored in the second memory through auxiliary data input means, such as keys of the electronic musical instrument, and are read out of the second memory to be displayed on the display means.

    摘要： An inertia-related engine speed fluctuation is computed when the engine is rotated without ignition. A load-related engine speed fluctuation is computed when the engine is rotated with ignition and combustion. The inertia-related engine speed fluctuation is indicative of an inertia moment that is variable in accordance with equipments connected with the engine. The load-related engine speed fluctuation is indicative of an engine load. When estimating the engine load, the inertia-related engine speed fluctuation is considered for removing an influence of the inertia moment on the engine load. The estimated engine load is used for controlling the engine. It is possible to consider the inertia moment into an engine control.
