摘要： A method of measuring the rate of transmission of a vapor through a test sample using a mass spectrometer. The test sample is sealed to a gas cell defining a gas chamber, covering an opening in the gas chamber. A droplet of water including isotopes of mass number placed in the gas chamber and the gas cell is introduced into a vacuum chamber adjacent a mass spectrometer. After a sufficient time for evaporation of the liquid to saturate the gas chamber with vapor and for the output of the mass spectrometer to stabilize, the partial pressure of vapor in the vacuum chamber is measured using the mass spectrometer. The measure partial pressure is used to derive the rate of transmission of the vapor through the test sample.

摘要： The present invention relates to an elastic surface-wave device, and more particularly to an elastic surface-wave device of a greatly increased performance, compared with a prior art elastic surface-wave device, and which is compact. The elastic surface-wave device includes a substrate including a surface having a region which is formed by at least a part of a spherical surface and is circularly continuous, and a surface acoustic wave generator which is provided in the surface region of the substrate and generates surface acoustic waves propagating in a continuous direction of the surface region. The surface acoustic wave generator generates surface acoustic waves in such a manner these waves can propagate only in the continuous direction without being diffused in a direction crossing the continuous direction along the surface region.

摘要： An ultrasonic sensor for use in an ultrasonic micro spectrometer includes a concave surface transducer having a concave ultrasonic wave transmitting/receiving surface and a plane transducer having a plane transmitting/receiving surface. The concave surface transducer is capable of transmitting converging ultrasonic waves toward a specimen, wherein the waves are reflected from the surface of the specimen and are received by the plane transducer which outputs electric signals corresponding to the intensity of the reflected ultrasonic waves. Based on a signal output from the ultrasonic sensor, a digital oscilloscope and FFT analyzer forms a distribution of spectral intensity indicating the intensity of the reflected wave as a function of frequency. The digital oscilloscope and FFT analyzer further forms a distribution of spectral phase indicating the spectral phase of the reflected waves as a function of frequency. Either the distribution of spectral intensity or of spectral phase can effectively be analyzed for evaluating elastic characteristics and structure of a specimen.

摘要： In a method and an apparatus for exciting acoustic waves, the surface of an object is irradiated with coherent parallel energy beams and coherent focusing energy beams which have different frequencies in such a manner that they overlap each other to generate interference fringes (concentric circles) propagating from outside to the inside at propagation speed which is higher than a specific acoustic speed of the object. The acoustic waves are excited in accordance with distortion distribution generated in the surface of the object attributable to the photo-thermal effect of the interference fringes, the acoustic waves being focused to a small region in the object, the position of which is determined by the specific acoustic speed of the object and the propagation speed of the interference fringes.
