A fuel tank body has a double-layer structure composed of an inner tank shell and an outer tank shell, so that an inter-tank-shell space is formed therebetween. The first and second conveyers are operable to drive main drive rollers provided at start ends of the conveyers by bringing the rollers into abutment against side surfaces of rearmost pallets in the advancing direction, thereby urging and collectively driving a plurality of pallets which are connected together forwardly of the rearmost pallets in a state in contact with the rearmost pallets. Certain embodiments include mechanisms to limit the forward progression of the pusher along the track, such as a brake mechanism, and certain embodiments include mechanisms to block access to product located on the track. Thereafter, at least one learned model of the plurality of learned models is identified as the basis for the new domain model when the new domain input statistical characteristics compare favorably with the statistical characteristics of the features in the prior input corresponding to the at least one learned model. The composition may also include an extracellular matrix scaffold component of any formulation, and further include added cells, proteins, or other components to optimize the regenerative process and restore cardiac function. According to the improved image processing method and the improved image processing apparatus embodying the method, an image having good image quality can be recorded in such a manner that image information which has been photoelectrically read out is subjected to image processing and the dodging is carried out to the image information output for recording.
