  • Patent number: 10752183
    Abstract: A laminated composite interior part includes a first member made of synthetic resin and having a mating surface; and a second member made of elastically deformable synthetic resin and having a plate portion substantially parallel to the mating surface. The plate portion has integrally-formed and interspersed protrusions protruding toward the mating surface. The second member is placed on the first member with distal end portions of the protrusions being in contact with the mating surface. Cushioning properties are provided by elastic deformation of the protrusions, caused as the protrusions' distal end portions are relatively pressed against the mating surface. Flexural rigidity of each of the protrusions against a compressive load is anisotropic about its axis, so that the protrusion is flexurally deformed in one direction about its axis with the distal end portion thereof sliding on the mating surface. Surface roughness of the mating surface is less than 0.20.

  • Patent number: 10545017
    Abstract: The purpose of the present invention is to provide an overlay error measuring device which measures an overlay error with high accuracy even when a lower layer pattern is disposed under a thin film and a sufficient signal amount cannot be ensured. The present invention proposes an overlay error measuring device provided with an arithmetic processing unit for measuring a pattern formed on a sample on the basis of a signal waveform obtained by a charged particle beam device. The arithmetic processing unit finds a correlation with the signal waveform using a partial waveform obtained on the basis of partial extraction of the signal waveform, forms a correlation profile indicating the correlation, and measures an overlay error using the correlation profile.
