Title: Smelting reduction method and furnace thereof
Inventor: ISOZAKI SHINICHI
IPC: C21B13/00
Filed: 1988-12-21
Abstract: PURPOSE:To efficiently restrain damage of furnace wall refractory by generating circular flow of slag with stirring gas from side blow tuyeres and deviating the flame direction with oxygen jet through this circular flow to near the furnace circumferential direction. CONSTITUTION:The side blow tuyeres 3 are arranged at plural positions to circumferential direction of the furnace so that gas outlets 31 is positioned to the furnace inner wall brought into contact with slag layer in the furnace and the gas blowing direction thereof is deviated to the furnace center in the horizontal direction by the angle theta (about 30 deg.-75 deg.). By this constitution, the oxygen jet 5 through a top blowing lance 2 is formed in the slag so as to direct to the furnace wall direction and the deviated stirring gas is blown from the side blowing tuyere 3 to generate the strong circular flow of the slag. By this method, the tip part of the flame formed with the oxygen jet 5 is caused to flow to the furnace circumferential direction, and the flame is prevented or relaxed from collision to the furnace wall and the damage of the furnace wall refractory is restrained.

Title: Rambling-drive detection apparatus
Inventor: FUKUDA JUNICHI
IPC: B60W30/00
Filed: 1994-12-22
Abstract: PURPOSE: To obtain a rambling-drive detection apparatus which judges whether a drive is a rambling drive or not by detecting the visual line of a driver. CONSTITUTION: The visual-line direction of a driver is detected by a visual-line detection sensor 10 which uses an infrared difference image or the like, and a stop position and the stop time are measured by a by-stop-point X-Y- coordinate counter 38 and a within-stop-range stop-time measuring part 28. In a rearview-mirror and side-view-mirror position estimation part 20, the visual- line position on a rearview mirror or a side-view mirror of a driver is estimated on the basis of detected visual-line data, and the number of confirmations is measured by a rearview-mirror and side-view-mirror number-of-confirmations counter 22. In a rambling drive, the number of confirmations is reduced as compared with that in a normal drive.  As a result, when the number of confirmations is compared with a prescribed threshold value, a rambling-drive judgment part 40 judges whether a drive is a rambling drive or not, and it drives a warning part 42 so as to generate a warning. A judgment-reference threshold value is changed on the basis of a signal from a preceding-vehicle judgment part 32 or a running-environment judgment part 34, and a judgment reference value according to a running road is set.
