摘要： Iron oxide agglomerates incorporated with the carbonaceous material having a particle size within a range of about 10 to 30 nm are prepared upon production of reduced iron agglomerates. Then, the iron oxides agglomerates incorporated with the carbonaceous material were laid thinly at a laying density of less than 1.4 kg/m.sup.2 /mm or lower on a hearth of a moving hearth furnace. Subsequently, the iron oxide agglomerates are heated rapidly such that the surface temperature of the iron oxide agglomerates reaches 1200.degree. C. or higher within one-third of the retention period of time of the iron oxide agglomerates in the moving hearth furnace. Then, the iron oxide agglomerates are reduced till the metallization ratio thereof reaches 85% or higher to form reduced iron agglomerates and then the reduced iron agglomerates are discharged out of the moving hearth furnace. With the procedures, reduced iron agglomerates of a high average quality can be obtained at a high productivity.

摘要： A light for an infrared ray) emitting member or a reflective (or an infrared ray reflective) medium is mounted at a predetermined position on an object upon which an image is projected. The light emitting member or the reflective medium is acquired in the coaxial direction of an image projecting unit by an (infrared ray) image pick-up means and video signals obtained by the (infrared ray) image pick-up means are digitized in an image processing unit, such that a highly luminous point of the light emitting or reflected portion occurs in a binary image. A central value of a primary moment on the binary image including the high luminous point, is calculated in real time, and the calculated data is fed back to an electrically-driven driving portion of the image projecting unit, so that the image may be continually projected at the predetermined position. The electrically-drive turntable automatically controls the image projecting direction including the direction of light. The image projecting apparatus projects the image by automatically tracking the position of the moving light emitting member or the reflective medium. Consequently, the image can be continually projected at the predetermined position, automatically tracking the moving object such as an airship or a balloon, so that it can be available as an effective advertizing medium or news.
