Title: Production of extra low nitrogen ingot
Inventor: TAKEMURA YOUZOU
IPC: B22D11/108
Filed: 1981-04-28
Abstract: PURPOSE:To produce an extra low nitrogen ingot inexpensively in desiliconization (de-Si) or desiliconization and dephosphorization (de-S, -P) treatments of molten iron by blowing an oxidizing agent into molten iron in the absence of nitrogen then refining and continuously casting the same by conventional methods. CONSTITUTION:In de-Si, de-S, -P states, an oxidizing agent is blown onto molten iron by using a gas such as Ar or CO2 other than gaseous N2. At this time, the amt. of the using oxidizing agent is set at least 6 Nm<3>/t-molten iron expressed in terms of gaseous nitrogen. The resultant low N molten iron is subjected to decarbonization refining by oxygen blowing according to conventional methods, to low N steel. Then while nitrogen addition to the molten steel is prevented, the molten steel is continuously cast, and the extra low N steel ingot reduced of N in steel to about <=10ppm is produced.

Title: Magnetic bubble element
Inventor: MATSUDERA HISAO
IPC: G11C19/08
Filed: 1978-05-26
Abstract: PURPOSE: To obtain the reading element in the bubble lattice structure by securing a distinct detection whether the magnetic wall state of the bubble is S=1 or S=0.  
     CONSTITUTION: In case the magnetic bubble is transferred via the driving rotary magnetic field, the transfer line is provided and the bubble is transferred by the magnetic charge induced through the driving rotary magnetic field. In case the state of the bubble magnetic wall features S=1, the drift is caused in the shifting direction to the slope of the magnetic field. And the fact that the stability degree to the drift according to the shape of the transfer line was founded. In other words, when the bias magnetic field is turned to the front side, the drift is steady S=1 and with the rotary magnetic field turned counterclockwise. But the drift becomes unsteady in the case of the clockwise magnetic field, and then the bias magnetic field is heightened to extinguish the bubble. Accordingly, the bubble under S=1 is extinguished although the bubble under S=0 is normal, and as a result the reading  becomes possible according to presence or absence of the bubble.
