  • Patent number: 9994059
    Abstract: When data about plural book sheets, each belonging to one of plural chapters, are edited to bind the plural book sheets by a casing-in operation in such a manner that chapter range images, which indicate the respective ranges of the plural chapters, are displayed on an edge so that the chapter range images that are adjacent to each other are arranged at different positions from each other in the top-bottom direction, a marker image emphasizing the chapter range image is adjacent to the chapter range image indicating the range of a chapter having book sheets the number of which is less than or equal to a predetermined threshold.

  • Patent number: 9489590
    Abstract: A color mode determination apparatus includes: a color mode determining section that obtains image data including a plurality of visualization objects, performs polychrome/monochrome determination on whether the visualization object is polychromic or monochromic, and performs color mode determination on whether the image data is polychromic image data or monochromic image data based on a result of the polychrome/monochrome determination; and an overlap determining section that determines whether a predetermined visualization object is overlapped with other visualization objects when the polychrome/monochrome determination is performed for the predetermined visualization object. The color mode determining section changes a determination target range of the polychrome/monochrome determination depending on whether the predetermined visualization object is overlapped with other visualization objects.

  • Patent number: 4112141
    Abstract: A solder for filling or padding operations on automobile bodies, consisting essentially of 2.0-7.0 Wt% antimony, optionally less than 5.0 Wt% of tin and the balance of lead. This solder is inexpensive and exhibits good physical properties at high temperatures principally due to its high solidus temperature of above 240.degree. C. The use of this solder is particularly advantageous when the filling or padding operations are preparatory to a surface coating operation in which a high baking temperature is employed for hardening enamel paint or varnish.
