A packaging machine and a weighing apparatus low in equipment cost, small in installation space, and allowing a reduction in time required from the manufacture of packaged bodies to the completion of weighing to increase productivity. In an embodiment multiple sensors are situated at various locations in a building detecting physical quantities. Alternatively, before tin plating, a seed layer is formed on the surface. The processing element is also configured for generating an alternate mapping for the first and second images based on comparing areas of pixels in the first and third images that are non-corresponding according to the mapping function. The integrated train control system includes a master controller cooperating with features of EP-60, CCBII, LEADER, and Wired DP to control car control devices through ITC network. Stress values of the building structural components arranged in the strength distribution diagram 33 are computed based on stress computational data of the building structural components consistent with attributes of the building structural components.
