摘要： A data conversion apparatus is provided for reading a document for a display screen and generating a display image for another display screen which has a different aspect ratio from the former display screen, where the document is composed of control statements written along with character strings or image information. The data conversion apparatus obtains the document from an external unit and converts the character strings and the image information in the document into display image elements based on conversion information. The data conversion apparatus judges whether a storage includes a blank for storing the display image elements at an appropriate position based on the conversion information. The data conversion apparatus writes the display image elements into the blank if it judges that the storing unit includes the blank; the data conversion apparatus assigns a new storage area in the storage and writes the display image elements into the new storage area if it judges that the storing unit does not include the blank.

摘要： In producing thin slabs by continuous casting, a method is developed in which internal defects are reduced to improve a production yield. Narrow sides of cast slabs are cooled in a controlled manner to produce cast slabs having a projection in a center of each of the narrow sides to a height of 5-10 mm above the level of the edge portions, and squeeze reduction with a reduction of 10-45% is carried out while an unsolidified portion of the narrow sides of the slab is within 50-80% of the thickness of the cast slab.
