Abstract: A processed article is provided with a plurality of IDs having the same information for machine reading but difference to be confirmed visually. The information such as the production lot number which is read from the plurality of IDs by the reading device is the same, but these plurality of IDs are different in external appearance, for example in size or color. By corresponding such difference of the plurality of IDs in the external appearance to the positional information in the processing apparatus for the article, new information can be added to the ID without introducing a new ID printer or a reading device. A prompt measure to a trouble in production is made possible based on the information such as the position of the article. Also the defective processed article can be easily selected, thereby improving the production yield and achieving a cost reduction.

Abstract: A solar cell module is provided at the position of a heat collecting plate inside a heat collector, at the position of its window member or at the position of its bottom plate. With such constitution, a hybrid system can be achieved in which the hot air can be led into a house while maintaining the performance of solar cells making use of amorphous silicon semiconductors.In the case where solar cells are provided at the position of the heat collecting plate, a resin used as a filler has so high a thermal resistance that the heat conduction to the air may be insufficient to make it impossible to obtain hot air having a sufficiently high temperature. To solve this problem, the solar cell module is made to have a smaller thermal resistance on the non-light-receiving side than the thermal resistance on the light-receiving side.
