    摘要： An apparatus examines the internal structure of an object disposed substantially in a medium such as air, which essentially totally reflects acoustic signals in the 1-200 MHz frequency range. The apparatus has an acoustic transducer that emits and receives acoustic signals in the 1-200 MHz frequency range and an acoustic coupler that acoustically couples the acoustic transducer to the object. The acoustic coupler is adapted to essentially retain a body of fluid such as water between a section of the surface of the object and the acoustic transducer for carrying acoustic signals in the 1-200 MHz frequency range between the acoustic transducer and the object.

    摘要： A method and device for mounting a sensor to a surface that is flat in one dimension and flat or curved in a second dimension. The mounting method results in stable self-centering attachment of the sensor to the surface across a wide range of radii in the second dimension of the surface. A fixed distance and angle between the sensor components and the surface is automatically maintained despite wide changes in the radius of the surface. An attachment means is provided that is secure, repeatable, and reusable. Additionally, a means of maintaining a clear unobstructed window between the sensor and surface is provided.

    摘要： The present invention provides a downhole method and apparatus to determine the percentage of oil based mud or water based mud filtrate contamination in a formation fluid sample. The present invention determines the percentage of filtrate contamination in a sample comprised of a mixture of crude oil and an oil based mud filtrate or of formation brine and a water based mud filtrate. The filtrate contamination percentage is determined from a relationship between the densities of uncontaminated formation fluid and filtrate. Filtrate may oil based or water based mud. The density of formation fluid is determined from a series of high precision pressure measurements of formation fluid at a plurality of depths in a hydrocarbon producing well. The density of filtrate is provided by downhole measurements with a flexural mechanical resonator or by measurements made downhole or at the surface.

    摘要： A gas concentration sensor includes a measurement chamber for measuring a concentration of a specific gas component in a gas under measurement; an inflow path for allowing inflow of the gas under measurement thereinto and an outflow path for allowing outflow of the gas under measurement therefrom; a reflection wall for reflecting an acoustic wave; and an acoustic wave transmitting-receiving element having a transmitting-receiving surface adapted to transmit an acoustic wave toward the reflection wall and receive an acoustic wave reflected from the reflection wall. The concentration of the specific gas in the gas under measurement is detected on the basis of a propagation time between transmission of the acoustic wave and reception of the reflected acoustic wave. When a predetermined member having the sensor attached thereto is placed in a horizontal plane, the transmitting-receiving surface faces downward. A recess is formed in a peripheral portion of the reflection wall. The recess is receded toward a back surface of the reflection wall, namely, in a direction away from the transmitting-receiving surface.

    摘要： A device for measuring thickness and/or rate of thickness increase of a film comprises at least one piezoelectric element, and first and second electrodes in contact with the piezoelectric element. A method of measuring thickness and/or rate of thickness increase of a film comprises applying a voltage across a piezoelectric element from a first electrode to a second electrode, thereby causing the piezoelectric element to vibrate, and measuring the rate of vibration of the piezoelectric element. Heat may be applied to the piezoelectric element. The piezoelectric element may be formed of quartz crystal, e.g., IT-cut.

    摘要： A preferred, non-destructive method for characterizing sputter target cleanliness includes the steps of sequentially irradiating the test sample with sonic energy predominantly of target sputter track areas; detecting echoes induced by the sonic energy; and discriminating texture-related backscattering noise from the echoes to obtain modified amplitude signals. These modified amplitude signals are compared with one or more calibration values so as to detect flaw data points at certain positions or locations where the comparison indicates the presence of at least one flaw. Most preferably, groups of the flaw data pixels corresponding to single large flaws are bound together so as to generate an adjusted set of flaw data points in which each group is replaced with a single, most significant data point. The adjusted set of flaw data point is used to calculate one or more cleanliness factors, or to plot a histogram, which characterizes the cleanliness of the sample.
