    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.

    摘要： Pellets incorporated with a carbonaceous material of the present invention contain a carbonaceous material and iron ore mainly composed of iron oxide. The maximum fluidity of the carbonaceous material in softening and melting, and the ratio of iron oxide particles of 10 &mgr;m or smaller in the iron ore are within the range above a line which connects in turn points A, B and C shown in FIG. 1, including the line. This permits the production of pellets incorporated with a carbonaceous material having excellent thermal conductivity and high strength. Reduction of the pellets incorporated with a carbonaceous material produces reduced iron having high strength after reduction and a low fines ratio with improved productivity.

    摘要： A carbonaceous material is controlled such that the amount of carbon is from 7 to 60 mass % based on the total amount of iron and Zn in a starting mixture comprising one or more of ducts containing iron oxide and Zn oxide and a binder in an amount to bond the dusts, and water is added to prepare green pellets incorporated with the carbonaceous material. Then, dry pellets prepared by drying the thus prepared green pellets into a reduction furnace, the dry pellets are heated by heat transfer, mainly, radiation such that a temperature elevation rate is from 3 to 13° C./sec within a temperature range from 150 to 900° C. of the pellets, thereby reducing Zn oxide and evaporating Zn, as well as reducing iron oxide to produce reduced iron pellets.
