摘要： Detection of gas characteristics, especially the detection of the gas composition, the temperature and/or humidity of a gas, by measuring the speed of sound with a sound sender (1) and a sound receiver (2) both mounted on common structure (3). The invention further concerns a method for determining the humidity of the scavenge air of an internal combustion engine. The invention further concerns a speed of sound based gas sensor arrangement adapted to measure gas characteristics, especially the gas composition, the temperature and/or the humidity of a gas, comprising a sender (1), a receiver (2) and a signal processing unit. The speed of sound is determined by driving the sender (1) and receiver (2) at different operation cycles in order to differentiate between the different travel times of the sound through the gas and the common structure (3) of solid material.

摘要： An object characteristics measurement apparatus of the invention includes a surface acoustic wave device. The surface acoustic wave device includes: an interdigitated electrode that is formed on a first surface on a piezoelectric substrate, excites an elastic wave, and receives reflection based on the elastic wave; a reflector that has a third surface and a fourth surface between the interdigitated electrode and a second surface orthogonal to the first surface in a propagation direction of the elastic wave, the third surface being formed at a position different from that of the first surface in a normal direction of the first surface, the fourth surface connecting an end of the first surface, which is formed perpendicular to the normal direction of the first surface, to the third surface; a reaction field that is formed between the interdigitated electrode and the reflector, in which the measured object is to be loaded; and a propagator that is formed between the reflector and the second surface. The characteristics of the measured object are determined based on a surface acoustic wave that is separated from an elastic wave and a bulk wave and from a bulk wave where the elastic wave propagates along the reaction field from the interdigitated electrode, is reflected by the fourth surface, and is received by the interdigitated electrode and where the bulk wave is reflected by the second surface and is included in the surface acoustic wave received by the interdigitated electrode.

摘要： An ultrasonic testing sensor and an ultrasonic testing method are provided which achieve a high sensitivity of three-dimensional ultrasonic testing and a high S/N ratio, do not require development of a sensor for each inspection object, and reduce the cost of developing a sensor.
The ultrasonic testing method is performed with the use of the ultrasonic testing sensor while a total length d, extending in a direction parallel to an ultrasonic scanning direction, of ultrasonic elements (5) to be simultaneously excited with a single exciter is controlled to be in a range ensuring that 2d ▪ sinθ = n ▪ λ, where λ is a wavelength of an ultrasonic wave (3), n is an integer of 1 or 2, and θ is an angle at which the ultrasonic wave (3) is incident.

摘要： An array probe 3 is provided with an array probe body 32 having a plurality of transducers 31 linearly arranged. The array probe is provided with a vibration insulating member 4 that is installed onto a transducer surface 33 to absorb the vibrations of the transducer surface, and an installation frame 5 for installing the vibration insulating member. The vibration insulating member has an opening part 41, and the width dimension of the opening part is smaller than the width dimension of the transducer surface. By installing the vibration insulating member having the opening width dimension corresponding to the distance from a test object surface of a target flaw onto the transducer surface, ultrasonic testing is performed, whereby even for a flaw near the surface, flaw echo is made less liable to be buried in surface echo, and the flaw can be detected easily.

摘要： A method for inspecting a component is provided. The method includes generating an image of the component, generating a signal indication mask, and generating a noise mask using a signal within the signal indication mask. The noise mask facilitates reducing a quantity of prospective signals contained in the signal indication mask. The method further includes utilizing the signal indication mask and the generated noise mask to calculate the signal-to-noise ratio of at least one potential flaw indication that may be present in the image.

摘要： Zur Ermittlung von fertigungsbedingten Verstimmungen (Mistuning) von in integraler Bauweise gefertigten Laufrädern (BLISKs) auf der Grundlage der Identifikation von Schaufeleigenfrequensen werden die einzelnen Schaufeln unabhängig voneinander erregt und dabei die Schwingungsantwort zur Berechnung der jeweiligen Schaufeleigenfrequenz und der Verstimmung gemessen. Nährend des Messvorgangs werden die nicht untersuchten Schaufeln mittels einer temporär angebrachten, jeweils identischen Zusatzmasse zusätzlich verstimmt, so dass die Messung der Schwingungsantwort der erregten Schaufel störende Kopplungseffekte aus dem eigenfrequensnahen Bereich der Schaufeln verschoben und dadurch eliminiert werden.

摘要： A minor axis oscillating ultrasonic probe (U) which provides on a rotary holding table (1) a group of piezoelectric elements (2) arranged in a major axis direction and have an acoustic lens (6) on the ultrasonic wave transmitting/receiving surface, houses the rotary holding table (1) in an enclosed container (3) in the minor axis direction of the group of piezoelectric elements (2) so as to rotate and oscillate, scans mechanically in the minor axis direction ultrasonic waves transmitted/received to/from the ultrasonic wave transmitting/receiving surface of the group of piezoelectric elements (2), fill the enclosed container (3) with liquid (L) as an acoustic medium, and has a means of absorbing unnecessary ultrasonic waves propagating in a major axis direction between the ultrasonic wave transmitting/receiving surface and the inner peripheral surface of the enclosed container (3), wherein projections (6b) are respectively provided as the means of absorbing unnecessary ultrasonic waves on the opposite end sides of the acoustic lens (6) corresponding to the major axis direction. Accordingly, the minor axis oscillating ultrasonic probe can reduce working steps in the production of the probe, ensure the sealing of the enclosed container and the absorption of unnecessary ultrasonic waves, and reduce the weight of the probe to provide excellent operability at diagnosing.
