  • Patent number: 10688779
    Abstract: A screen printing apparatus includes an inspection region setter and an operation stop controller. The inspection region setter sets an inspection region in an inspection plane that intersects with a moving path of a mask until the mask positioned at a printing-job performing position moves to a mask shelter position by the moving mechanism. In addition, the inspection region setter excludes a passing region of the mask from the inspection region while the mask to be positioned at the mask shelter position passes over the inspection plane from the printing-job performing position.

  • Patent number: 10571712
    Abstract: A lens barrel that prevents an oscillation phenomenon caused by vibrations occurring when a lens of an image blur correction mechanism shifts. A first cylinder is engaged in the cam cylinder and caused to move in a direction of an optical axis by rotation of a cam cylinder. A second cylinder supports a lens holding member, which moves in a direction different from a direction of an optical axis so as to correct for an image blur, and is engaged in the cam cylinder and caused to move in the direction of the optical axis by rotation of the cam cylinder. The second cylinder has a first vibration isolation pin that is engaged with the first cylinder movably in the direction of the optical axis.

  • Patent number: 10342439
    Abstract: A strain sensor element comprises a laminated film which has a magnetic free layer, a spacer layer, and a magnetic reference layer. The free layer has a variable magnetization direction and a out-of-plane magnetization direction. The reference layer has a variable magnetization direction which is pinned more strongly than the magnetization of the free layer. The spacer layer provided between the free layer and the reference layer. A pair of electrodes is provided with a plane of the laminated film. A substrate is provided with either of the pair electrodes and can be strained. The rotation angle of the magnetization of the free layer is different from the rotation angle of the magnetization of the reference layer when the substrate is distorted. Electrical resistance is changed depending on the magnetization angle between the free layer and the reference layer, which allows the element to operate as a strain sensor.
