Title: Decarburization refining method for chromium-containing molten steel
Inventor: SAIDA YUUZOU
IPC: C21C7/00
Filed: 1980-05-19
Abstract: PURPOSE:To effectively accelerate the decarburization reaction effect of Cr-contg. molten steel by specifying the relations between the height from the surface of the molten steel in a vacuum ladle degassing device up to a lance port for oxygen blowing and the velocity of O2 at the interface of molten steel. CONSTITUTION:A ladle 3 containing molten steel 5 to be refined is put into a vacuum vessel 1, and the inside of the vessel 1 is evacuated by a steam ejector 8 and a condenser 9. While an inert gas is being introduced 4 from the bottom of the ladle 3, gaseous O2 is blown through an oxygen lance 6 into the molten steel 5, thereby allowing decarburization reaction to take place. In this case, O2 blowing conditions are controlled in such a manner that the relations between the height l between the port part of the lance 6 and the surface of the molten steel 5 and the velocity Vm of O2 at the molten steel interface are kept within the range of the area D shown in the fugure. As a result, the decarburization efficiency, decarburization speed, the amount of Cr loss, the splash formation, etc. of the Cr-contg. molten steel are considerably improved. Here, the velocity Vm of O2 is the equation Vm=(4dXQ/a)/(0.428l+d) [where d; the diameter of the lance port (m), a; the sectional area of the lance (m<2>)l; the height of the lance (m), Q; the flow rate of O2 blowing (Nm<3>/sec)].

Title: Cache memory erasing system
Inventor: SATO YOICHI
IPC: G06F12/08
Filed: 1987-03-20
Abstract: PURPOSE:To eliminate a need of a selector which gives the address of a V bit part, to shorten the delay time of the cache mishit/hit discriminating pass by using the address array unuse time due to cache miss to erase all entries. CONSTITUTION:When a following cache access request (address=A) is accepted at a timing t1, the request address A is set to a logical address register 10 and an entry designating part (a) of an address array 32 of the request address A is set to an entry address register (EAR) 11 through a selector 20. When the entry having the entry number (a) is checked at a timing t2 to discriminate cache mishit, value '0' of a counter 12 is loaded to the EAR 11 and contents of the counter 12 are counted up by one. At a timing t3, the entry having entry number 0 of the unuse-side V bit is cleared and contents '1' of the counter 12 are set to the EAR 11 and contents of the counter 12 are counted up by one furthermore. At a timing t12, the entry having entry number 9 is cleared.

Title: Video disk player
Inventor: IGARASHI SHIGEMI
IPC: G11B9/06
Filed: 1982-04-23
Abstract: PURPOSE:To ensure an effective kickaction of a stylus and to improve the picture quality, by using a driving electronic circuit having a variable time constant to a circuit which kicks the stylus of a video disk player out to the adjacent signal groove. CONSTITUTION:A microcomputer 11 delivers a kicking signal 12 having the standard pulse width to kick out a diamond stylus (not shown in the diagram). The signal 12 is amplified 13 to charge a capacitor 14 as well as to supply a current to a kicker coil 10. At the same time, a time constant varying signal 15 is delivered from the computer 11 to indicate the standard time constant and then to control a time constant variable attenuator 16. When no signal 12 exists any more, a capacitor 14 starts its discharging. In this case, the attenuator 16 is actuated by the signal 15. Therefore the discharged current given from the capacitor 14 flows to the coil 10 with a prescribed time constant. The kicked result of the diamond stylus is decided by the computer 11. If the result is not satisfactory, the pulse width and the time constant indication 15 are varied. Thus the effective kicking is made possible for the stylus of a video disk player.
