Title: Method for cleaning molten steel in tundish
Inventor: SASAI KATSUHIRO
IPC: B22D11/11
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To quickly and efficiently reduce oxygen conc. in a tundish by specifying the inner diameter of a nozzle for blowing inert gas and the dipping depth of the nozzle into the tundish at the time of executing continuous casting while preventing the air oxidation of molten steel by blowing the inert gas into the tundish. SOLUTION: The inner diameter of the used nozzle for blowing the inert gas it regulated to >=40mm, and the nozzle is set to the position where the distance between the tip part 9 of the nozzle 8 and the upper end 10 of the tundish (the dipping depth 11 of the nozzle) secures >=1/4 of the tundish depth 12 before pouring the molten steel into the tundish 1. At the time of blowing the inert gas in this condition, the flow rate of the inert gas jet can be reduced and the whole body in the tundish can be kept to positive pressure condition by increasing the dipping depth of the nozzle. Therefore, even when the tundish is low in air-tightness, the entrapment of the air from the outside of the tundish can be prevented and the oxygen concn. is quickly and efficiently reduced.

Title: Brake control device
Inventor: SAWADA MAMORU
IPC: B60T13/66
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To perform the braking control of a brake booster by driving an other brake assist means when the brake booster cannot exploit its boosting action sufficiently. SOLUTION: A variable pressure chamber pressure P1 is detected based on the signals from a variable pressure chamber pressure sensor (S110). A variable pressure chamber pressure P2 is detected based on the signals from a constant pressure chamber pressure sensor (S120). Also a pressure difference (P1-P2) between the variable pressure chamber pressure P1 and constant pressure chamber pressure P2 is calculated (S130). Then it is judged whether or not a pressure difference (P1-P2) between the variable pressure chamber and constant pressure chamber lowers below a specified judgment value ΔPTH (S140). When it is judged yes, because a vacuum booster function is judged to be lowered, an auxiliary means as a pressure amplifying mechanism is executed in order to compensate for the reduced amount of function (S150).
