    摘要： A method of stirring molten metal by repeatedly sucking and rapidly discharging part of the molten metal into and out of a refractory cylinder having a lower opening end immersed in the molten metal in a ladle, comprises operating the stirring under a condition that an inner diameter (d) of the refractory cylinder is less than 1,000 mm, a relation between the inner diameter (d, mm) of the refractory cylinder and weight (W, ton) of the molten metal in the ladle is d/W.sup.0.5 >30, and an immersed depth of the refractory cylinder is within 200-700 mm. A pressurized gas for discharging the sucked molten metal out of the cylinder is introduced thereinto in an inclined direction relative to a vertical line against a point on an opposite inner wall of the cylinder at least 500 mm above the maximum suction level of the molten metal in the cylinder.A refractory cylinder operated in the above manner according to the invention comprises a flange connection between an uppermost and an intermediate cylinder parts of the cylinder at a location higher than the maximum suction height of the molten metal and a further flange connection between the intermediate cylinder part and a lowermost cylinder part. The refractory cylinder comprises at its immersed end a flow restricting opening to obtain more strong stirring the molten metal.

    摘要： Ribs are unitarily formed on an outer wall surface of a casing to compensate for an inclination of an inner wall surface corresponding to a draw angle provided for molding the inner wall surface. The direction of pins of a casing connector which connects an electronic control circuit of a printed circuit board accommodated within the casing to external wiring coincides with the direction of insertion of a checker connector. Alternatively, a protrusion or recess may be formed on a jig device on which the casing is placed for connection to an operation checking apparatus.

    摘要： In an air-fuel ratio control with a learning control, a first correction values stored in a memory in correspondence to intake condition of a combustion engine and fuel injection time are renewed in response to an air-fuel ratio of mixture sensed in an exhaust of the combustion engine and a second correction value also stored in the memory is renewed in dependence on a difference between the first correction values stored in correspondence to the same intake condition. The first correction values are used to correct a basic fuel injection time determined by the operating condition, while the second correction value is used to correct an ineffective fuel injection time. Fuel is injected for an interval which is a sum of the corrected basic fuel injection time and the corrected ineffective fuel injection time.
