  • Patent number: 11904407
    Abstract: A laser welding apparatus is equipped with a laser head that emits a laser beam and an airflow forming unit that forms sheet-shaped airflows, in which the airflows formed by the airflow forming unit traverse an optical path of the laser beam emitted from the laser head, the airflows traversing the optical path at multiple positions which are spaced from each other in a direction along the optical path in a same direction. The airflow forming unit has an opening between the airflows at the multiple positions, the opening penetrating in a direction in which the airflows traverse the optical path.

  • Patent number: 11873859
    Abstract: A clamper mechanism for a motion guide device includes a clamper block having tapered faces, clamper rolling elements arranged between the tapered faces and both left and right side faces of a track member, and a clamper rolling element holder attached to the clamper block with an interposition of an elastic member. When an elastic force exerted by the elastic member acts in a direction in which the clamper block and the clamper rolling element holder are separated from each other, the clamper rolling elements bite the tapered faces to bring the clamper block into a state restrained to the track member. When an external force against the elastic force exerted by the elastic member acts, the clamper rolling elements are brought into a free state within the tapered faces to bring the clamper block into a state not restrained to the track member to exert a stable clamping force.
