The object of the invention is to provide a rubber crawler which has an excellent driving performance without rubber breakage and a process for manufacturing the same. The LED assembly includes a heat sink and an LED illuminator secured with respect to an LED-supporting region of the heat sink with heat-dissipating surfaces extending therefrom. After the display signals are stored for the part of the line into the storage device, the display signals are outputted while additional display signals for another part of the line are concurrently stored into the storage device. Body support unit motion parameters are defined by either of two optional control devices, specified as a rotary wheel motion controller and as a crank arm motion controller. to obtain an extract containing acidic soluble saccharides of soybean, and inoculating and fermenting the extract with probiotics that are able to decompose monosaccharides and disaccharides, but substantially not able to decompose trisaccharides or tetrasaccharides. The method comprising: delivering a supply of the coating material to a distributive surface of an ultrasonic horn, the distributive surface controlling a flow of the coating material to an active edge of the ultrasonic horn, and atomizing the coating material at the active edge of the ultrasonic horn and directing the atomized coating material onto a surface of the print substrate.
