摘要： A system and method for determining the atomization characteristics of fluids being emitted by a nozzle is disclosed. In one embodiment, a fluid is emitted through a nozzle while simultaneously sensing vibrations occurring within the nozzle. The vibrations provide information about the atomization characteristics of the fluid. By comparing the sensed vibrations to vibration patterns produced by known fluids through the same or a similar nozzle, the atomization characteristics of the fluid being tested can be predicted. In one embodiment, for instance, the atomization characteristics of a fluid may be determined as a function of velocity or flow rate through the nozzle.

摘要： There are provided an inspection device, an inspection method, and an inspection program for accurately inspecting a minute structure having a movable portion by using a simple method. A test sound wave is inputted and frequency characteristic of a sensor output voltage amplitude responding to the input of the test sound wave is analyzed. The maximum frequency and the minimum frequency of the device is calculated from estimated use conditions and it is judged whether it is possible to detect a desired characteristic in the frequency band. More specifically, the device is judged to be good or bad depending whether the response characteristic in a predetermined frequency band exceeds the minimum characteristic level as a threshold value.

摘要： The present invention uses ISTS to measure trenches with near- or sub-micron width. The trenches can be etched in a thin film on in a silicon substrate. One step of the method is exciting the structure by irradiating it with a spatially periodic laser intensity pattern in order to generate surface acoustic waves. Other steps are diffracting a probe laser beam off the thermal grating to form a signal beam; detecting the signal beam as a function of time to generate a signal waveform; determining surface acoustic wave phase velocity from the waveform; and determining at least one property of the trench structures based on the dependence of surface acoustic wave phase velocity on the parameters of the structure.

摘要： In a method of non-destructive testing of a panel of composite insulation material (1), a portion of a surface (2) of a test panel is heated by applying a heat source for a predefined time or until a predefined amount of energy has been imparted to the panel. The heat dissipation from the surface (2) of the panel is then measured over time in order to produce a heat dissipation characteristic for the test panel, which is then compared with reference heat dissipation characteristics from panels of known composition in order to provide an initial indication of the composition of the panel. The surface (2) of the panel is then struck with a tuned hammer in order to pass a pulse of energy therethrough which generates vibrations within the panel. These vibrations are again monitored over time in order to produce a characteristic vibratory modes for the panel, which is then compared with reference data from panels of known composition in order to provide a confirmation of the composition of the test panel.
