摘要:
A short between terminals of a linear solenoid controlled by an electronic control in an automatic transmission is detected by sensing when a PWM duty ratio set by a feedback control operating the linear solenoid is less than a reference duty ratio. The reference duty cycle is calculated to be between a range of expected normal duty ratios in the absence of the short and a range of expected short duty ratios in the presence of the short.

A character generation system, in which multiple operations are performed in parallel to achieve higher-speed processing, includes a circuit for converting character contour data into coordinate axis data, a circuit for generating dot data expressive of the contour from the coordinate axis data, a circuit for sorting the coordinate axis data in a prescribed sequence and a circuit for performing image drawing operations in correspondence with the sorted data. At least two of these circuits include sufficient channels to permit the performance of their designated functions in parallel. The required image drawing time is reduced by a decrease in the required number of accesses to a bit map using a polygon approach to character generation. The invention selects only the starting point and terminating point for its image drawing process out of the coordinates which form the polygon and draws a character on the bit map while generating the coordinates incremented by a predetermined value from the starting point to the terminating point. The invention also relates to a method for image drawing.

A method for stirring chrome-containing molten iron comprises mechanically stirring chrome-containing molten iron contained in a refining vessel by the use of an impeller having a rotation axis in the vertical direction where the refining vessel is such that the horizontal cross section of the inner wall thereof is circular around the central axis of the vessel in the vertical direction and the impeller, as integrated with the axial rod covered with a refractory, rotates around the central axis of the axial rod, as the rotation axis thereof. The stirring mode is regularly or irregularly switched between a concentric stirring of the molten iron in a state where the rotation axis of the impeller is centered in the central axis of the vessel and an eccentric stirring of the molten iron in a state where the rotation axis of the impeller is decentered from the central axis of the vessel.
