    • In a vehicular control object determination system, the position of an object detected by a radar device is stored by a detection position memory, and a predetermined area having the position of the object as the center is set as the determination region by a determination region setter. When the determination region set for one of two objects is passed through by the other object, the passing direction is determined by a passing direction determiner. During this process, the direction in which a fixed object or an object dropped on the road moves relative to a preceding vehicle is a direction in which the fixed object or the dropped object on the road approaches the subject vehicle with the preceding vehicle as a reference. Then, a control object determiner excludes from determination of the control object an object for which the passing direction determined by the passing direction determiner is a direction approaching the subject vehicle, thereby preventing the fixed object or the dropped object from being erroneously determined as the control object when the preceding vehicle passes over the fixed object or the dropped object on the road.

    • This invention relates to a method of producing stainless molten steel by a smelting reduction treatment - decarburization treatment of Cr raw materials such as Cr ores, Cr ore pellets and so on consecutively and at high treating speed in one container. In the smelting reduction, an inert gas is blown from bottom tuyeres to form an upheaving part of the molten metal on its surface and the inert gas is blown to this upheaving part. The molten metal is thereby caused to disperse into a region of the slag where the Cr materials float, so that the reduction of Cr is accelerated by C. On the other hand, decarburizing O.sub.2 is blown into the molten metal from a top lance, while O.sub.2 for a post combustion is blown into the slag, so that a post combustion region is formed mainly in the slag, and the slag is forcibly agitated by blowing the gas from the side tuyere, so that a heat generated by the post combustion is caused to transfer to Cr ores at high heat transfer efficiency, and a high post combustion is secured, as maintaining the post combustion ratio to be more than 0.3. After having completed the smelting reduction, the slag is discharged. The molten metal is agitated by blowing the decarburizing O.sub.2 diluted with the inert gas from the top lance, and blowing the inert gas from the bottom tuyeres.

    • A process for treating water vapor generated in concentrating an aqueous urea solution wherein a urea synthesis effluent containing urea, unreacted ammonium carbamate and water from a urea synthesis zone is subjected to a plurality of decomposition stages, the pressures of which stages are stepwise reduced to decompose and separate substantially all of the unreacted ammonium carbamate from the aqueous urea solution. The aqueous urea solution which still contains small amounts of ammonia and carbon dioxide is concentrated to obtain crystalline urea or molten urea substantially free of water. The water vapor generated in concentrating said aqueous urea solution which contains small amounts of ammonia and carbon dioxide is cooled for condensation thereby forming a dilute aqueous ammonium carbamate solution which is subjected to rectification under a gauge pressure below 25 kg/cm.sup.2 to distil off a gaseous mixture of water vapor, ammonia and carbon dioxide, introducing the gaseous mixture into the unreacted ammonium carbamate decomposition stage using rectification under substantially the same pressure as the pressure of the rectification for the dilute aqueous ammonium carbamate solution to remove the water vapor from the gaseous mixture, and recovering the resultant ammonia and carbon dioxide together with a gaseous mixture of ammonia and carbon dioxide which is generated in the unreacted ammonium carbamate decomposition stage.
