The invention relates to dry free-flowing filler for forming a support structure in a bone cavity. The male connector includes a U-shaped shroud axially surrounding a male terminal having an opening generally perpendicular to the male terminal’s longitudinal axis. As the material is transported toward each of the outlets by the augers it is crushed or ground to a small size. A torsion spring supported by the front plate has a first end portion contacting the pivot member and a second end portion contacting the contact plate. The image display device includes a light emitting drive means that drives a light emitting means, based on an analog display signal inputted to the pixels, and a light emitting control switch for controlling a light-on or light-off of the light emitting means on one end of the light emitting drive means in each pixel.
