Title: Transmission control device for vehicle
Inventor: KOBAYASHI KOJI
IPC: F16H61/04
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To help vehicles to negotiate corners quickly and avoid uncomfortable feelings imposed on drivers by providing special corner-end control adapted to work when the drivers intend to go out of corners. SOLUTION: In a condition that vehicle cornering is detected (S50), and when the drivers intend acceleration from their stepping on the accelerator pedal (S51), it is determines that the vehicle is to go out of corners (S52).

Abstract: PURPOSE:To facilitate starting of an operation for continuous casting of a thin metallic strip by housing the molten metal flowing out of a nozzle straightly into a receiving tray at the beginning of the start of casting until the molten metal flow stabilizes, then starting cooling, thereby forming a thin metallic strip. CONSTITUTION:The molten metal is made to flow out of a nozzle tip mounted on a nozzle holder 5 of a tundish 2 and is brought into contact with the peripheral face of a cooling drum 10 under rotation, by which said metal is cooled and the thin metallic strip 11 is continuously cast. The spacing L between the nozzle tip 7 and the cooling drum 10 is set large at the beginning of the start of the casting so that the molten metal flow 13 is dropped directly into the receiving tray 14 disposed at lower part thereof. After this molten metal flow 13 stabilizes, an outflow hole 3a in the bottom of the tundish 2 is closed by a stopper 9 and the tundish 2 is moved toward the drum 1 to narrow the spacing L to about <=1mm. The molten metal is again supplied to cast the thin metallic strip 11 on the peripheral face of the drum 10. This thin metallic strip is taken up on a coiling drum 15. The spacing L is thereafter adjusted further to the value corresponding to the target thickness of the thin metallic strip 11 at need.
