Abstract: PURPOSE:To surely detect an engine rotational speed even though the engine rotational speed is low upon a start, so as to surely start the engine by controlling the injection of fuel into an engine in accordance with a variation in current or voltage applied to a starter upon a start. CONSTITUTION:When a contact ST in an ignition switch 3 is turned on so as to drive a starter 7, current running through the starter 7 due to a rotating load of a crank shaft of an engine is discretely increased. When the current is increased, the voltage applied to the starter 7 decreases. When the voltage applied to the starter 7 becomes lower than a reference voltage value, a wave shaping circuit 14 delivers a rectangular wave signal. Accordingly, a main control part 10 recognizes this rectangular wave signal as an engine rotational speed signal so as to detect an engine rotational speed, and operates a fuel injection pump 6 in accordance with the engine rotational speed, and output signals from various sensors 5 in order to control the injection of fuel for the engine. After the engine starts, the fuel injection is controlled in accordance with a result of detection of an engine rotational speed sensor 4.

Abstract: PURPOSE:To manufacture air-crushed slag of constant quality, by controlling the lifting speed of an auxiliary hoist which slants a slag pan according to the signal of measured weight of the slag pan so as to keep constant the weight-changing rate of the slag contained in the slag pan. CONSTITUTION:Molten slag 4 is transferred to a slag spout 3 by slanting the slag pan by means of an auxiliary hoist 7. The quantity of the slag transferred to the spout 3 is found as a weight change by means of a load cell type weighing device 8 installed in a crane, the weight change rate dW/dt being computed by an arithmetic unit 9. The computed dW/dt is compared with previously set dW/dt 11 by means of a dW/dt control unit 10, and a command for increasing or decreasing the lifting speed of the auxiliary hoist 7 is given from the unit 10 to the driving unit 12 of the auxiliary hoist motor 13 so as to keep the compared value constant. The speed of revolution of the auxiliary hoist motor 13 is controlled according to the command to control the lifting speed of the auxiliary hoist 7. As the result, the quantity of slag 4 fed to the spout 3 is kept constant. Hereby, the slag is mixed with air sprayed from a blower 2 which is previously controlled at a constant air quantity to form a air-crushed slag 14, which is piled up on the yard 1 as particles.
