Five cases of the fracture of the sternum due to use of a seat belt were reported. According to the Fowler's classification, our cases were classified as TYPE: 1 case, Type IV: 3 cases and Type VIII: 1 case. With regard to four cases (type I and IV), the mechanism of the fracture was direct violence.A case associated with the injuries of interspinal ligaments of the thoracic spine, the mechanism of the fracture was indirect violence as flexion-compression injury. All cases were treated with rest and immobilization. The importance of radiographic examination on the sternum in patient of seat belt injury.

Mixture formation of diesel spray impinged on an extruded surface, which was a top of cylindrical column, was investigated experimentally. A diesel spray was impinged vertically to the extruded surface. The behaviors of impinged spray were observed using a high-speed drum camera. A spray volume was estimated from the photographs. Effect of cylindrical column diameter on spray behavior was investigated. Adhering fuel was measured by a primitive “wiping by paper and mass measuring” method under various conditions. Air-fuel ratio in spray was calculated from spray volume and adhering fuel. As the result, the behavior of diesel spray impinged on an extruded column was strongly influenced by the diameter of the extruded column. From the measured results, it is clear that the air-fuel ratio in spray in the extruded column diameter of 45 mm was larger than those in the other columns.
