    摘要: Image signals of moving subjects which are imaged by a slit camera, and time information generated by a time information generator after it has been reset by a start trigger signal, are successively stored in and erased from a large-storage-capacity memory on a first-in, first-out basis. After elapse of a predetermined time period after a record trigger signal has been supplied from a record trigger generator, a storage time control circuit controls the memory to stop storing and erasing the image signals and the time information, and keeps the image signals and the time information stored which have been stored before the memory stops storing and erasing the image signals and the time information. The image information of the subjects and the time information associated with the image information can be stored in the memory within a storage time that depends on the storage capacity of the memory.

    摘要: A method for smelting reduction of iron ore, comprises the steps of: introducing iron ore into a preheat and prereduction furnace and preheating and prereducing the iron ore, a prereduction degree being less than 30%; charging the iron ore, carbonaceous material and flux into a smelting reduction furnace; blowing oxygen gas, through decarburization nozzles and post-combustion nozzles placed in a top end of an oxygen lance, into the smelting reduction furnace, the top end of the oxygen lance being located so as to be between a top level and a bottom level of a slag layer; blowing a stirring gas through side tuyeres placed in a side wall and bottom tuyeres placed in a bottom wall of the smelting reduction furnace; and controlling a flow amount of the oxygen gas and the stirring gas so that an oxidation degree of an exhaust gas generated in the smelting reduction furnace ranges 0.4 to 0.9 and still a temperature of the exhaust gas ranges 300.degree. to 1300.degree. C. when the exhaust gas is introduced into the preheat and prereduction furnace. Furthermore, an apparatus for smelting reduction of iron ore comprises: a preheat and prereduction furnace; a smelting reduction furnace; a top blow oxygen lance with decarburization nozzles and post-combustion nozzles; side tuyeres and bottom tuyeres.

    摘要: An apparatus for producing high surface area active carbons in a safe and commercially advantageous manner by the alkali metal hydroxide-based activation method is provided. Using pushers (9a-k), the apparatus circulates containers (C) along a container travel line (8) connecting the elements: material feeding section (1).fwdarw.inlet side gas replacement chamber (2).fwdarw.tunnel kiln (3).fwdarw.cooling zone (4).fwdarw.water injection chamber (5).fwdarw.outlet side gas replacement chamber (6).fwdarw.reaction mixture discharge port (7) to form a closed circuit. During the travel of the containers, a series of steps is performed, namely the steps of charging of the containers with raw materials (carbonaceous material and alkali metal hydroxide-water mixture), dehydration, activation of the carbonaceous material with the alkali metal hydroxide, cooling, water injection and discharge of the reaction mixture. The gas exhaustion system for the tunnel kiln (3) and water injection chamber (5) is provided with a water seal (10).

    摘要: The present invention relates to a method of carrying out a smelting reduction of Cr raw material as Cr ores, Cr ore pellets and so on for directly producing high Cr molten metal in a furnace provided with bottom gas blowing tuyeres, side gas blowing tuyere and a top blowing lance. An inert gas is blown from the bottom tuyere to form an upheaving part on the surface of the molten metal, and an inert gas is blown from the side tuyere against the upheaving part, whereby the molten metal is diffused into a region of the slag where Cr raw material fly so as to accelerate reduction of Cr raw materials by C in the molten metal. On the other hand, O.sub.2 for decarburization is blown from the top lance into the molten metal, and at the same time O.sub.2 for a post combustion is blown into the slag, whereby a region post combustion is formed mainly in the slag, and the slag is agitated compulsively by gas blown from the side tuyere so that heat caused by the post combustion is transferred to Cr ores at high heat transfer efficiency. A ratio of the post combustion is maintained to be more than 0.3 for securing a high post combustion.
