  • Publication number: 20210025698
    Abstract: This device for three-dimensionally measuring a linear object includes a stereo camera, a transmission-light illuminator, and an arithmetic device. The stereo camera images a linear object. The transmission-light illuminator faces the stereo camera so that the linear object is placed between the transmission-light illuminator and the stereo camera. The arithmetic device acquires a three-dimensional shape of the linear object. The stereo camera acquires a transmitted-light image of the linear object captured while the linear object is illuminated by the transmission-light illuminator. The arithmetic device acquires the three-dimensional shape of the linear object based on the transmitted-light image.

  • Publication number: 20070012477
    Abstract: An electronic component is mounted on the surface of a printed wiring board. A heat conductive member is received on the surface of the electronic component. A joint material is interposed between the electronic component and the heat conductive member. The joint material is made of material containing Ag in a range exceeding 3 wt % and In. The inventors have demonstrated that voids decrease at the boundary between the joint material and the electronic component as well as at the boundary between the joint material and the heat conductive member as the content of Ag increases in the overall weight of the joint material. The joint material is allowed to enjoy a higher heat conductivity as compared with a conventional solder material. The joint material allows the heat conductive member to efficiently receive heat from the electronic component.
