  • Patent number: 10291848
    Abstract: When a user viewing an image of a conversation partner displayed on a display moves, a displayed image is more easily switched to an image reflecting a position of the user after the movement. When an image of a first user is displayed on a display of a second user, the image of the first user taken by an imaging device and an image of a background taken by the imaging device are acquired, and the acquired images are composited with each other, thereby displaying on the display a composite image in which the first user is positioned in front of the background. Moreover, when a movement of the face of the second user with respect to the display is detected, transition processing of causing the composite image displayed on the display to transition from a state before the detection of the movement of the face is carried out.

    Abstract: The present invention is a clad material for an electric contact, including a base material composed of a Cu-based, precipitation-type age-hardening material, and a contact material composed of an Ag alloy bonded to the base material. On a bonded interface between the contact material and the base material, a width of a diffusion region including Ag and Cu is 2.0 ?m or shorter. The clad material is produced by bonding each other the contact material and the base material having undergone solutionizing and age-hardening beforehand, suppressing the diffusion region from expanding after bonding. The present invention is capable of providing an electric contact, which achieves higher conductivity, without sacrificing property of the Cu-based, precipitation-type age-hardening material.
