  • Patent number: 11594047
    Abstract: An article distinguishing system includes: an identification information acquisition unit, an image capture unit that captures an image of an exterior of a target article, a determination unit that derives a degree of matching between the captured image of the target article and exterior image data stored in a storage unit, and determines whether or not the current state is a normal state in which exterior image data for which the degree of matching is a determination threshold value or more is present, and a learning processing unit that executes learning processing if it has been determined by the determination unit that the current state is not the normal state. The learning processing is processing for storing the data of the captured image as new exterior image data in the storage unit in association with the identification information acquired by the identification information acquisition unit.

  • Patent number: 8735754
    Abstract: A power transfer switch in which a cross bar including a movable contact is rotated to come into contact with one of fixed contacts disposed on left and right sides of the cross bar. The cross bar has a non-circular cross-section including a protruded piece on left and right, and a rotating angle thereof is greater than a rotating allowable angle of the movable contact between the fixed contacts. A through hole into which the cross bar is inserted with play is formed on a base portion of the movable contact, and a step portion for receiving the protruded piece of the cross bar and a spring housing portion extended in a direction of a central axis of the movable contact are formed in the through hole. A compression spring is accommodated in the spring housing portion to cause the cross bar to elastically hold the movable contact.

  • Patent number: 8492202
    Abstract: In a structure of a semiconductor device, a Si chip and a metal leadframe are jointed by metallic bond via a porous joint layer made of high conductive metal, having a three-dimensional network structure and using Ag as a bonding material, and a film containing Zn oxide or Al oxide is formed on a surface of a semiconductor assembly contacting to a polymer resin. In this manner, by the joint with the joint layer having the porous structure mainly made of Ag, thermal stress load of the Si chip can be reduced, and fatigue life of the joint layer itself can be improved. Besides, since adhesion of the polymer resin to the film can be enhanced by the anchor effect, occurrence of cracks in a bonding portion can be prevented, so that a highly-reliable Pb-free semiconductor device can be provided.
