  • Patent number: 9739697
    Abstract: A drop impact tester comprises a holder configured to hold a test piece and release the test piece such that the test piece drops in freefall; an impact surface disposed under the holder such that the test piece dropped from the holder hits the impact surface; and a drop angle measurement device configured to measure a drop angle which is a value correlated with an angle between a major surface of the dropped test piece and a reference plane. The tester further comprises an impact measurement device configured to move the impact surface from its first posing state to its second posing state to adjust an angle of the impact surface with respect to the reference plane based on the drop angle. The impact measurement device is configured to measure a drop impact applied to the impact surface by the dropped test piece or another test piece.

  • Patent number: 8598486
    Abstract: A method and an apparatus for treating return ores using plasma, capable of treating sintered return ores generated in a sintering process in a steel maker or return ores (iron ores) employed in other ironmaking process such as FINEX. The method of treating return ores using plasma includes: providing return ores sorted out by a sorting process; and bonding the return ores by fusing and agglomerating the return ores using plasma. Also, an apparatus for treating return ores using plasma includes a plasma heating device used to fuse and agglomerate sorted return ores. The return ores of a predetermined grain size are fusion-bonded and agglomerated using a flame of a plasma heating device. Particularly, the return ores can be treated in a massive amount to enhance productivity of a fusion-bonding process of the return ores. Furthermore, a great amount of sintered return ores generated in the sintering process can be subjected to a fewer number of re-treatment processes.

  • Patent number: 8128800
    Abstract: A method of manufacturing a mold for producing a light guide panel and a method of manufacturing the light guide panel using the mold are presented. The mold is made by manufacturing a pattern master on which a fine pattern is formed. A side mold for forming a light-receiving surface of a light guide panel is immersed in an electrolyte containing metal ions, along with the pattern master. A voltage is applied to the electrolyte and the side mold such that the fine pattern on the pattern master is transferred to the side mold with the metal ions in the electrolyte, forming a prism pattern forming portion on the side mold. The prism pattern is formed on a light-receiving portion of the light guide panel using the side mold thus prepared. The shape accuracy and surface accuracy of the prism pattern are improved by using the presented method.
