    摘要: In a vibration-resistant interferometer, an interference fringe image obtained by an image capturing means is analyzed and an optical path difference between a reference light component and an object light component is maintained at a predetermined value with reference to the result of this analysis, thereby making its optical system simple in structure, easy to adjust, and inexpensive to manufacture and maintain. A Fizeau-type interferometer, a CCD camera for viewing an interference fringe, a computer for analyzing the interference fringe image information obtained by the CCD camera to calculate the shape of the sample surface or the amount of vibration or inclination of the sample surface, and a PZT driving circuit for transmitting predetermined driving signals to PZTs are provided.

    摘要: To connect a holding bracket to a muffler, an improved connecting structure therebetween is proposed. The muffler includes a tubular case and two end plates which are connected to axially open ends of the tubular case by means of caulking thereby to form around each axially end of the case a caulked raised portion. The bracket includes a metal rod and a metal plate. The metal plate includes an upper gripping part which grips the caulked raised portion and a lower gripping part which grips the metal rod. The metal plate has between the upper and lower gripping parts an intermediate wall portion which is put on the metal rod, so that when the muffler is properly held by the supporting bracket, entire weight of the muffler is substantially supported by the metal rod.

    摘要: Each sub-area of an object surface is measured with a partial overlapping on the peripheral edges of at least adjacent sub-areas. Surface state data of each sub-area is acquired and calculated to produce a reconstructed image. The images of the reconstructed sub-areas are made to partially overlap, and differences between the reconstructed images at selected points within the overlapped region are determined. A predetermined calculation is performed to determine coefficients, for altering the relative alignment of the reconstructed images, which minimize the differences. The reconstructed images are contiguously joined together by application of the coefficients. Thus, boundaries between the reconstructed images are joined contiguously into an accurate form.
