摘要： A method for manufacturing agglomerates of fired pellets comprising the steps of: the first pelletization step of adding and mixing fluxes to fine iron ores containing 30 to 95 wt. % of those of 0.125 mm or less in particle size to form a mixture and to pelletize the mixture into green pellets; the second pelletization step of adding powder cokes containing 80 to 100 wt. % of those of 1 mm or less in particle size to the green pellets, in amount of 2.5 to 4.0 wt. % to the fine iron ores, to prepare, through pelletization, green pellets coated with the powder cokes; and the sintering step of charging the green pellets coated with the powder cokes into a grate type sintering machine to manufacture the agglomerates of fired pellets. And furthermore, in another method for manufacturing agglomerated of fired pellets, fine iron ores containing 10 to 80 wt. % of those of 0.044 mm or less in particle size and powder cokes containing 20 to 70 wt. % of those of 1 mm or less in particle size are used.

摘要： A linearly polarized light beam is applied to the surface of a film and is reflected therefrom. The beam is then split into three light beams by three or four optical flats. These light beams are applied to photoelectric conversion devices after passing through analyzers with fixed analyzing angles. The photoelectric conversion devices convert the beams into electric signals representing the intensities of these light beams. Two ellipsometric parameters .psi. and .DELTA. are calculated from these three electric signals.

摘要： A covering is applied onto the outer surface of a pile including a steel pipe or the like to surround a predetermined length thereof so as to reduce a frost heaving force or negative friction acting on the pile in a frigid area. The covering is closely adhered by an adhesion layer the like to the pile over a given length thereof. This given length is between 0.5 and 5 m. The covering member includes a smooth-surfaced plastic covering or elastic covering. A rugged surface covering may be provided below the smooth surfaced covering.
