This paper reports on the influence of coarse aggregate on the fracture properties of concrete subjected to high temperatures up to 800℃. The fracture properties were evaluated based on tension-softening curves which were determined by polylinear approximation through inverse analysis of load versus crack mouth opening displacement (CMOD) curves, obtained from wedge-splitting tests using a dedicated analysis program. The follow conclusions were found in this study: The initial cohesive stress of mortar was higher than that of concrete. And the fracture energy of concrete was higher than that of mortar.

The"CASIO SUPER CYBER CROSS(JG-200)"is an infrared (IR) communication digital watch for children. In addition to watch, alarm and stopwatch function, it has apparatus for short message, game playable alone or with another watch, and TV remote controller. Its communication distance is within 5 meters and the angle is ±15゜. It also is provided with a removable quaking booster, which operates at alarm time, in game and when recieving data. This paper describes the outline of the spesification, IR communicate protocol, and the major components of the watch.
