Title: Method and apparatus for divided refining
Inventor: NAKAJIMA HIDEMASA
IPC: B22D11/119
Filed: 1993-06-07
Abstract: PURPOSE:To make the refining of a small lot of material adaptable by using a refining apparatus capable of being arranged at the position, at which an immersion tube can be dipped into molten steel, and executing casting after the treatment of the molten steel. CONSTITUTION:The molten sheet is received into a ladle 12 from a primary refining furnace 11 in the whole quantity. The secondary refining is executed with an RH apparatus 13, etc., at need. A part of the molten steel is cast into a continuous caster 14 from the ladle 12. By using the secondary refining apparatus 15 of the RH apparatus 15, etc., having the size fully incorporated in the inner part of the ladle 12, the treatment of the molten steel remaining in the ladle 12 is executed. That is, by using the refining apparatus 15 having the outer diameter smaller than the inner diameter at the bottom part of the ladle 12 and capable of being arranged at the position where the immersion tube can be immersed into the molten steel, the molten steel is again cast into the continuous caster 14a after executing the treatment of the molten steel. By this method, as the whole steel in one set of the ladle can be tapped at once from the primary refining furnace, the labor can be saved.

Title: Paper sheet recognition device
Inventor: KAWAHITO KATSUHIKO
IPC: G07D7/00
Filed: 1995-05-10
Abstract: PURPOSE: To accurately recognize paper sheets having passed thorough a circulation stage. CONSTITUTION: A paper sheet outline detecting means 1 detects the coordinates of the positions of plural outline points on the respective sides of the sheet paper, first. Then, an outline vector calculating means 2 finds outline vectors having their start and end points at respective adjacent outlines. When the displacement different between components of the adjacent outline vectors is abnormal, the outline points at the part are removed. Namely, an effective vector extracting means 3 extracts only outline vectors judged as effective vectors. Consequently, outline points of, for example, a broken or folded part of the paper sheet can be removed. And, a reference point and oblique angle calculating means 4 calculates a reference point and an oblique angle for correcting the rotation of the sheet paper.  Consequently, a trimming process means 5 accurately extracts image data of the paper sheet and a discrimination means 6 can perform accurate recognition.
