Abstract: There is provided a leakage determination system for an evaporative fuel processing system, which, even when pressure within the evaporative fuel processing system is temporarily increased e.g. due to an increase in the amount of generation of evaporative fuel in a fuel tank, is capable of performing an accurate leakage determination by eliminating the influence of the temporary rise in the pressure within the evaporative fuel processing system on the leakage determination. A pressure sensor detects pressure within the evaporative fuel processing system. Negative pressure is introduced from the intake system into the evaporative fuel processing system, whereby the pressure within the evaporative fuel processing system is reduced until the detected pressure becomes equal to a predetermined negative pressure. After the pressure reduction, the negative pressure is introduced from the intake system into the evaporative fuel processing system under predetermined conditions.

Abstract: Disclosed are a testing apparatus for and a method of measuring thermal stresses of concrete structures. Overcoming the limitations that conventional analytical access techniques have, the apparatus opens a new way to conveniently measure the thermal stress attributable to the heat of hydration generated in concrete structures indoors. Using a material different in coefficient of thermal expansion from concrete, the apparatus can directly measure the change in thermal stress of the concrete which is subjected to internal and/or external confinement. By using various materials, the thermal stress which varies depending on the confinement extent can be inferred. Additionally, an accurate prediction of the thermal stresses generated actually in concrete can be obtained, reflecting unclear physical properties of early-age concrete.

Abstract: A separator partitions an upstream side air passage of a bypass passage into first and second sub passages. A thermal flow sensor is attached to the separator facing the first sub passage. A convex is formed on the inner wall of an outer pipe defining the second sub passage. The convex protrudes toward the separator. Minimum flow passage area S2 of the second sub passage is smaller than minimum flow passage area S1 of the first sub passage, so that flow passage loss of the second sub passage is larger than flow passage loss of the first sub passage. Thus, measured air-flow amount average when the air-flow pulsates is corrected to be larger.
