  • Patent number: 10147028
    Abstract: A method and an apparatus for generating an information code is provided. In a generation apparatus, after data to be interpreted and data of an image to be displayed are acquired, a code figure that is provided with an image display region is generated and displayed on a display unit. After the code figure is displayed on the display unit in this way, when information designating an arrangement content of the image display region is inputted, an information code is generated. Specifically, an information code is generated in a form in which the image display region is newly arranged based on the arrangement content designated by the input, and a specification pattern region and a region to be interpreted are provided in positions other than that of the image display region. The information code generated in this way is displayed on the display unit.

  • Publication number: 20180240599
    Abstract: In a thin-film capacitor, an electrode terminal layer is divided into a plurality of parts by a penetration portion, and includes a frame portion as one divided part. The frame portion is disposed along an outer edge of the electrode terminal layer when viewed from the bottom surface side of the electrode terminal layer, and the frame portion can hinder deformation of the electrode terminal layer stretching or warping in a thickness direction or an in-plane direction, whereby such deformation can be prevented. Accordingly, in the thin-film capacitor, the electrode terminal layer is not likely to be deformed and an improvement in strength thereof is achieved.

  • Publication number: 20170334371
    Abstract: Provided is a multilayer composite interior component, in which boundary protrusions (20b) aligned in a row on both sides of a parting line (L) are arranged in a staggered manner so as to bend toward the boundary protrusions (20b) in the row opposite thereto. In this way, even when the boundary protrusions (20b) are separated from the parting line (L) by a predetermined distance (g1, g2) in order to maintain the strength of a divided mold, the boundary protrusions (20b ) bend and deform so as to fill in an empty part in the vicinity of the parting line (L) when a surface layer member (16) is pressed by fingers or a hand. As a result, a feeling of unevenness resulting from decreases in reaction force in the vicinity of the parting line (L) is minimized, thus making it possible to obtain a more uniform texture.

  • Publication number: 20170334370
    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: 9815418
    Abstract: Numerous fine projections (20) are formed interspersed on a plate-shape member (18), and the neutral plane (S) of each fine projection (20) is inclined at an inclination angle ? to the normal line (O) such that the contact center (Q) does not overlap with the base part in the plane direction of the surface (22), so when a pressing load (F) is applied, the moment acting on the fine projections (20) is large, and the fine projections (20) easily deform to bend in the respective inclination direction. By this means, the tactile softness (cushion properties) are improved by preventing the fine projections (20) from undergoing simple compression deformation in the axial direction, and stick-slip due to friction between the fine projections (20) and the surface (22) is avoided, making it possible to obtain a smooth and stable tactile softness.
