摘要： A mold is for press molding a metal plate and a resin material to produce a metal-resin composite. The mold includes an upper mold and a lower mold that sandwich the metal plate and the resin material. A cavity for arranging the resin material is provided by the upper mold and the lower mold. The upper mold has a recess into which the resin material leaking from the cavity is caused to flow.

摘要： A hydrogen permeability testing device can measure hydrogen amount(s) entering a metal material by electrochemical hydrogen permeation. The device may include: a metal specimen having a hydrogen entry face through which hydrogen enters, a hydrogen detection face on which the entered hydrogen is detected, and a metal plating formed on the hydrogen detection face to detect the entered hydrogen; a reference and counter electrode for making an electrochemical reaction progress; an electrolytic vessel provided on a hydrogen detection face side, housing the reference and counter electrode, and containing an aqueous sodium silicate solution having a freezing point of ≤0° C. and capable of suppressing residual current to ≤10 nA/cm2 when an electric potential of the hydrogen detection face is −1 to 1 V relative to the reference electrode; and a measurement unit which measures the amount of hydrogen based on a current value resulting from the electrochemical reaction.

摘要： A robot slider position setting device sets a position of a robot slider that moves while being loaded with a robot that performs predetermined work on a workpiece by using a tool provided at a distal end of the robot. The robot slider position setting device includes an interference-region-information storage unit that stores interference region information indicating an interference region with which the robot interferes in a predetermined ambient environment, an approaching-direction determination unit that determines a direction of an arm of the robot as an arm approaching direction such that the direction does not overlap the interference region by fixing a wrist rotation center of the robot in a state where the tool is in an orientation according to a predetermined working position, and a position determination unit that determines the position of the robot, slider based on the arm approaching direction determined by the approaching-direction determination unit.

摘要： A structural member is elongated in a longitudinal direction, and includes a first member made of a steel plate and a second member made of a steel plate, the first member and the second member being joined. In the structural member, a closed cross-sectional shape is formed by the first member and the second member in a cross section perpendicular to the longitudinal direction. The first member has a tensile strength of equal to or greater than 980 MPa, and includes a first hemming process part subjected to hemming bending at both end parts in a width direction orthogonal to the longitudinal direction. The second member has a tensile strength of equal to or greater than 980 MPa, and includes a second bonded part held in the first hemming process part at both end parts in the width direction and bonded to the first hemming process part by an adhesive.

摘要： A building time for building an additively-manufactured object is calculated on the basis of the inter-pass time and the welding pass time and is compared with a preset upper limit value, and welding conditions in a depositing plan are repeatedly modified until the building time is equal to or less than the upper limit value. Alternatively, corrections are repeatedly performed until the shape difference between a building shape of built-up object shape data relating to the additively-manufactured object created on the basis of the inter-pass time and the inter-pass temperature, and a building shape of three-dimensional shape data, is smaller than a near net value.
