Title: Method for continuously casting molten steel
Inventor: NAKAJIMA SATOSHI
IPC: B22D41/50
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To reduce the internal defect caused by enclosure of mold powder by setting the spouting quantity of molten steel so as to become the equal flowing speed at near both short side walls in a mold and pouring the molten steel into the mold from each spouting hole. SOLUTION: The immersion nozzle having the spouting holes 5 faced to both short side walls 6 in the mold, is set so as to shift this center axis in the direction along the side walls 5 from the center of the mold, and the molten steel is poured into the mold from each spouting hole 5. At this time, the spouting quantity from the immersion nozzle is decided so that the flowing speeds of the molten steel at near the short side walls 6 equal, and the molten steel is poured into the mold. In this way, periodical variation of the flow velocity on the surface of the molten steel can be restrained. As a means for adjusting the spouting quantity, e.g. the areas of the faced spouting holes 5 may be to mutually change in the immersion nozzle.  That is, many immersion nozzles having different cross sectional areas of the faced spouting holes 5, are prepared and the flow velocity sensors are arranged at near both short side walls 6 in the mold, and the testing operations are executed to find the suitable immersion nozzle.

Filed: 1988-03-25
Abstract: PURPOSE:To define the correspondence between trouble and a job class, whose schedule should be stopped, with the system definition in a local host by reflecting agreement relations, which indicate whether the schedule should be stopped for trouble of the local host or not, on scheduling of global jobs. CONSTITUTION:In a multihost system, a local job definition table 22 is provided with a trouble agreement flag which is turned on when a schedule stop flag is turned on, and the schedule stop flag corresponding to a local host 200 from which the turning-on state of the trouble agreement flag is reported is turned on in a global job definition table 12. When a trouble detecting means 26 detects partial trouble in the local host, a job execution request to local jobs belonging to the local job class is stopped by a local job schedule means 23 and a job execution request to local hosts belonging to the global job class is stopped by a global job schedule means 13. Thus, the system definition for trouble of the local host is simplified.

Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To achieve an increase in size of a screen and enhancement of picture quality by use of a holographic video method which employs a space light modulation element, without increasing the resolution of the space light modula tion element. SOLUTION: A hologram of the type reproducing a real image is displayed on a space light modulation element 250, and a field lens 260 is placed in the vicinity of the position of the reproduced real image to form a real image of the space light modulation element 250 in reduced size by use of the field lens 260. By forming the image in reduced size, the small diffraction angle of the space light modulation element 250 is increase to make it possible to display an image having a large field angle and high picture quality. By correcting distorsion by use of a display data processing part 110 when obtaining light modulation pattern data, the display of less distorted images is also made possible.  Further when data about a light modulation pattern are found through calculations, data about the light modulation pattern whereby undistorted images can be displayed by allowing for only considering a display optical system can be obtained using a relatively simple method.
