  • Patent number: 11984261
    Abstract: Various embodiments of the present disclosure are directed towards an integrated chip including a dielectric structure sandwiched between a first electrode and a bottom electrode. A passivation layer overlies the second electrode and the dielectric structure. The passivation layer comprises a horizontal surface vertically below a top surface of the passivation layer. The horizontal surface is disposed above a top surface of the dielectric structure.

  • Patent number: 8479616
    Abstract: A driving device includes a driving shank, a magnetic member mounted in the driving shank, a stop ring secured in the driving shank to stop the magnetic member, and an elastic member biased between the driving shank and the magnetic member. The driving shank has a first end provided with a mounting post and a second end formed with a mounting hole and a receiving chamber. The stop ring has an inner wall formed with a through hole and an outer wall provided with a toothed portion engaging a peripheral wall of the receiving chamber. The magnetic member has a peripheral wall formed with a stop flange that is movable to abut the stop ring. Thus, the elastic member provides a buffering effect to the magnetic member to reduce the pressure applied on the magnetic member.

  • Publication number: 20130057001
    Abstract: A gripping device comprises a base, claws, cylinders, and an electrical-operated magnetic disk. At least two claws are pivotally coupled to the base. The base is provided with a coupling portion, which can be pivotally coupled to an arm of an operation machine. Each claw is pivotally coupled to a first location of a vertical plate of the base. Each cylinder is pivotally coupled to one of the claws. When the claws hold together, an accommodating space can be defined, in which the disk is mounted. The disk is provided with a central shaft, which can be fitted in a central space of the base. Thereby, large pieces of metal can be gripped by the claws, whereas small pieces of iron can be picked up by the electrical-operated magnetic disk, so that one machine employing the gripping device can take large pieces of metal and small pieces of iron.
