Abstract: An optical fiber placement surface has formed thereon width-directional position restricting sections for partially restricting the position of an optical fiber ribbon in a width direction perpendicular to the axial direction of the optical fiber ribbon. A portion other than the width-directional position restricting sections serves as a width-directional position non-restricting section that does not restrict the position of the optical fiber ribbon in the direction perpendicular to the axial direction of the optical fiber ribbon. A pressing member is formed at a portion corresponding to the width-directional position non-restricting section. On the other hand, the pressing member is not formed at positions corresponding to the width-directional positional restricting sections. Thus, the optical fiber ribbon is not pressed at the width-directional positional restricting sections. Portions at which the optical fiber ribbon is not pressed by the pressing member are defined as non-main pressing sections.

Abstract: An aluminum electrical wire includes a conductor including aluminum-based core wires, and an insulating resin covering covering the conductor and having a thickness deviation of not less than 70%. The aluminum-based core wires contain 99 mass % of aluminum, and the conductor is constructed by concentrically twisting 19 or 37 of the aluminum-based core wires at the same pitch in a non-compressed state such that the aluminum electrical wire has a current capacity that is substantially the same as a current capacity of a copper electrical wire having a diameter that is substantially the same as a diameter of the aluminum electrical wire.

Abstract: Brightness profile data having a number of dimensions is extracted based on image data in a radial direction of an optical fiber, the brightness profile data representing features for each rotation angle of the optical fiber. Machine learning uses training data to create a prediction model that based on the brightness profile data determines a rotation angle of each pair of optical fibers is. The pair of optical fibers are rotated to the determined rotation angle and then fusion spliced. The training data indicates a correspondence relationship between the rotation angle of the optical fiber and brightness profile in the radial direction for each rotation angle of the optical fiber. The prediction model can determine a rotation angle of an arbitrary optical fiber based on brightness profile data of the arbitrary optical fiber.

Abstract: A rotatable connector device includes a stationary member, a rotatable member rotatably attached thereto, and a flat cable housed in an annular space between the stationary and rotatable members. One end of the flat cable is connected to a stationary-side connector fixed to the stationary member, and another end of the flat cable is connected to a rotating-side connector fixed to the rotatable member. The flat cable includes a folded-back portion bent and folded back at a middle section in a longitudinal direction thereof. The flat cable includes a predetermined number of conductor/conductors each comprising a copper alloy and wound up or rewound with bending kept at the folded-back portion. Each conductor satisfies Y≥14.175X2−249.35X+1406.9 for a bending radius of 4 to 8 mm, where X denotes bending radius, and Y denotes 0.2% yield stress, and has an electrical conductivity of 50% IACS or greater.
