A jig-type fishing lure has a weighted lure body holding a gravity-operated switch that controls the energization of an LED for illuminating fiber optic strands extending from the tail end of the lure body in proximity to a fishhook. The image information processing unit may be connected via a network to one or more radiation image reading devices and one or more image output devices for outputting the second radiation images. Moreover, the present invention relates to control units and wind power plants suitable for carrying out the present invention. A nozzle chamber structure is positioned on the substrate and defines a nozzle chamber and an ink ejection port in fluid communication with the nozzle chamber. Accordingly, the present invention correctly identifies multiple touch objects from a single touched cluster arising from an excessively large line-to-line space. In particular, the present invention relates to the planning, design and processing related to a mine location in a manner based on enhancing the extraction of material considered of value, relative to the effort andor time in extracting that material.
