  • Patent number: 7700932
    Abstract: A part of a human body is caused to contact the surface layer of a recording medium over which a plurality of metallic grains with an outside size of 200 nm or less are distributed. Then, secretions from the skin surface of the body part are caused to adhere to the surface layer of the recording medium to take the print of the body part. If light is irradiated to the recording medium, specific optical characteristics resulting from the surface structure of the recording medium are obtained, and therefore the color of the recording medium varies between a region having secretions and a region having no secretions. This renders it possible to record a visible print on the recording medium.

  • Publication number: 20090308189
    Abstract: Provided are a steering device and a feed screw mechanism. The steering device is made so easy in the adjusting work of a backlash that it can eliminate the backlash reliably, even if the precision of the thread of a feed thread shaft or a feed nut is poor, thereby to improve the rigidity and to reduce the manufacturing cost of the feed screw mechanism. An upper-side end portion feed nut is urged upward of FIG. 8 by an upper-side disc spring so that an upper-side flank face of the thread ridge of the upper-side end portion fee nut is brought into close contact with the lower-side flank face of the thread ridge of a feed screw shaft. On the other hand, a lower-side end portion feed nut is urged downward of FIG. 8 by a lower-side disc spring so that a lower-side flank face of the thread ridge of the lower-side end portion fee nut is brought into close contact with the upper-side flank face of the thread ridge of the feed screw shaft.
