摘要:
An inspection method for detecting a defect in a test object. A particulate is generated, then the generated particulate is introduced into a test object. Subsequently, light having high directivity is emitted such that the light passes in the vicinity of the test object to irradiate the particulate discharged from the test object, thereby making the particulate visible. An inspection apparatus for detecting a defect in a test object, including a particulate generator, a particulate introducing device which introduces the particulate into a test object, and a high directional light emitter emitting light passing in the vicinity of the test object and irradiating the particulate discharged from the test object to visualize the particulate. The inspection method and apparatus can detect a defect with high sensitivity and shorten an inspection time and a post-treatment time.

A sensor detects a vibration generated due to water leakage. An integration circuit integrates time intervals for which a signal obtained by absolute-value amplifying an output signal from the sensor exceeds a predetermined level within a predetermined period of time. The integration circuit performs the integration a plurality of times. A detection circuit selects a minimum value of a plurality of integration values obtained by the plurality of measurements as an integration value obtained when the influence of unrelated noise is at a minimum and compares the minimum value with a preset reference value. When the minimum value exceeds the reference value, the detection circuit determines the presence of water leakage, and when the minimum value is smaller than the reference value, determines the absence of water leakage.
