Abstract: A gas barrier film includes a substrate containing polypropylene as a main component, a gas barrier layer on a first surface of the substrate, and a coating layer on the gas barrier layer. Infrared spectroscopy of the first surface indicates a peak intensity (I1) at 1360 to 1390 cm?1 and a peak intensity (I2) at 1440 to 1480 cm?1 in a ratio satisfying the formula: (I1)/I(2)?1.65.

Abstract: A terminal crimping method includes covering an end portion of an electric wire with a fixing cylinder portion of a terminal including a flange portion which protrudes toward an outer periphery and which has at least one notch along a radial direction, caulking and crimping the fixing cylinder portion by a pair of dies including pressing projections, and caulking the fixing cylinder portion by the pressing projections to form crimp recess portions, in the caulking and crimping the fixing cylinder portion.

Abstract: A terminal crimping method includes covering an end portion of an electric wire with a fixing cylinder portion of a terminal, caulking and crimping the fixing cylinder portion by a pair of dies including pressing projections each having a flat shape in which a length in one axial direction is longer than a length in the other axial direction orthogonal to the one axial direction in a plan view, and caulking the fixing cylinder portion by the pressing projections to form crimp recess portions, in the caulking and crimping the fixing cylinder portion.

Abstract: The present disclosure relates to a laminate film for packaging. A laminate film according to an aspect of the present disclosure includes: a resin substrate having a heat sealing surface that constitutes one outermost surface of the laminate film; a coating layer made of a non-metallic material; and an underlayer disposed between the resin substrate and the coating layer. The resin substrate includes a first layer that is made of olefin copolymer and constitutes the heat sealing surface, and a second layer made of polypropylene, and the first and second layers are laminated and biaxially stretched.

Abstract: Rotation angle detection apparatus includes a magnet provided in a main gear and a magnetism detector positioned to face to the magnet. Magnet rotates integrally with main gear and magnetism detector detects changes in magnetic field of magnet so a rotation angle of main gear is detected. Main gear includes bottomed recessed part and plurality of mounting pins arranged in recessed part. Magnet is inserted in recessed part wherein a part of magnet protrudes from an upper end of the recessed part. Magnet inserted in recessed part is pressed against main gear by an elastically deformable retaining plate made of non-magnetic material. An outer portion of retaining plate includes plurality of mounting holes. Magnet inserted in recessed part is pressed against main gear by elastically deformed retaining plate and mounting pins inserted in mounting holes are thermally caulked wherein magnet is secured to the main gear.
