    摘要： Provided are a fluid conveying tube and a fluid leakage detecting system which can convey a cryogenic fluid such as LNG and which can quickly and reliably detect leakage of the fluid within the tube and the position of the leakage. An optical fiber 17 is continuously wound over the entire length of a flexible tube 1a. Leakage information detected by an optical fiber temperature sensor 21 is transmitted via a terminal 25a to an externally provided temperature measurement device. Meanwhile, when similar leakage occurs in the vicinity of a coupling section 3, the gas pressure inside the heat insulating layer 13a or the like increases due to the pressure of LNG within a corrugated tube 11 or a pressure generated as a result of evaporation of LNG. When the pressure inside the heat insulating layer 13a increases, information representing a change in the gas pressure is transmitted to a terminal 25b via a hollow pipe 27. A tube or the like is externally connected to the terminal 25b, and is connected to a pressure meter or like.

    摘要： A life prediction method of an electronic device in which the life prediction accuracy is more improved than that in a related art technique, and a design method of an electronic device based on the above method, are established. Life prediction is performed by incorporating either of a change in a physical property of a solder joint portion and a change in the fatigue life of a solder, the changes occurring when left at a high temperature. The change in a physical property of the solder joint portion or the change in the fatigue life of the solder is determined from the relationship between a heat treatment temperature and a heat treatment time. These changes are then formulated to be incorporated into the life prediction.
