摘要： An elastic wave generator includes an excitation coil, a magnetostriction oscillator around which the excitation coil is wound and an oscillator support. The excitation coil is wound around the oscillator, which is made of laminated magnetostriction sheets having a positive strain characteristic, in which length varies directionally upon magnetic excitation. The oscillator support has a first support surface bearing against a first end surface of the magnetostriction oscillator, intersecting the direction along which the length of the magnetostriction oscillator changes and a second support surface shrink-fit against a second end surface of the magnetostriction oscillator, intersecting the direction along which the length of the magnetostriction oscillator changes. Thus, the changes in the length of the magnetostriction oscillator due to the magnetic excitation of the excitation coil appearing at the first and second end surfaces is directly supported by the first and second support surfaces. The magnetostriction oscillator is shrink-fit by cooling so it may be placed between the support surfaces while cooled.

摘要： A vibration exciter machine has magneto striction elements (5,6) supported by a driven pile (2), for providing a vibration of up and down direction to the driven pile (2), and a drive circuit (D1) for controlling expansion and contraction movement of the magneto striction elements (5,6) by changing a supply time period of a current supplied to the magneto striction elements (5,6). By controlling of the drive circuit (D1) the supply time period of the current which flows in the magneto striction elements (5,6) is changed to control the expansion and contraction movement of the elements (5,7). Thereby a horizontal vibration component can be eliminated and only vertical vibration component can be transmitted to the driven pile material (2).

摘要： In a pattern inspection method, a master pattern serving as a reference and the continuous tone image of a pattern to be measured that is sensed by a camera are aligned. At least the position of a base in the continuous tone image of the pattern to be measured is detected on the basis of the master pattern. At least one threshold is set on the basis of the difference from at least the density value of the base. The continuous tone image of the pattern to be measured is binarized on the basis of the set threshold. The pattern to be measured is inspected by comparing the binarized pattern to be measured and the master pattern. A pattern inspection apparatus and alignment method are also disclosed.

摘要： An object of this invention is to confirm the content of a defect in real time. A defect image, corresponding master pattern image, failure designation button, nondefective designation button, dust designation button, piece number, piece coordinates, and the type of defect are displayed within a defect image region in an inspection status display window. When the nondefective designation button or dust designation button is selected, the inspecting apparatus recognizes that a defect corresponding to the selected button is negligible, and changes the inspection result of this defect from the defect to a nondefective.
