Abstract: An image processing system including a reconfiguration circuit, typically responding to fault detection. The image processing includes a data compressing unit for compressing image data generated by an image input terminal, a data storage unit for storing output compressed image data, a data decompressing unit for decompressing compressed data and for transferring the decompressed data to an output terminal. A control unit controls the system to compress and store image data, and then to repeatedly read out and transfer the stored data to the image output terminal. When a self diagnosis detects a fault in any one of the compressing unit, data storage unit, or data decompressing unit, the faulty unit is bypassed with a special data bus, thereby allowing system operating to continue.

Abstract: A vehicle such as a railroad car is constructed by connecting together side and roof blocks, each equipped with interior components, in a manner to improve the outer appearance of the connections between the side and roof blocks. Longitudinal beams of the side blocks are in contact with the under surfaces of gutters formed by the outer plate of the roof block. The side and roof blocks, equipped with the interior components, are connected together at the gutter portions by a welding which can be conducted solely from an exterior side of the vehicle. In the interior of the vehicle, the longitudinal beams and joints secured to the side blocks are connected to lateral beams of the roof block by rivets. Thereafter, a third interior plate is provided between interior plates of the side and roof blocks. Since the connections are formed at the gutter portions, the connecting operations can easily be conducted outside the vehicle and in a manner to assure a good from an exterior of appearance.
