  • Publication number: 20260063034
    Abstract: By drilling a blast hole using a crawler drill, rock quality around the blast hole can be judged at the same time. A rock quality judgment device performs judgment using a differential pressure value between an actual feed pressure and a feed command pressure (differential pressure value judgment) and performs the differential pressure value judgment by comparing the actual feed pressure of a feed motor with the feed command pressure. The rock quality judgment device judges, when the actual feed pressure of the feed motor is lower than the feed command pressure while the drilling is performed, the rock quality as unstable rock. In contrast, the rock quality judgment device judges, when the actual feed pressure is higher than the feed command pressure, the rock quality as stable rock.

  • Patent number: 9760815
    Abstract: With this invention, color shifting correction is performed first based on shifting amount information indicating a shifting amount with respect to the scanning direction on an image carrier of each image forming unit, and halftone processing is then performed, thus suppressing generation of moiré due to the color shifting correction, and forming a high-quality image. To this end, an image forming engine has color shifting amount storage units C, M, Y, and K (black) which store actual shifting amounts with respect to ideal scan directions on image carriers C, M, Y, and K in image forming units C, M, Y, and K. Color shifting correction amount arithmetic units C, M, Y, and K calculate color shifting correction amounts for respective color components on the basis of the stored color shifting amounts.
