  • Patent number: 8753955
    Abstract: A method of fabricating a nonvolatile memory device includes forming trenches in a substrate defining device isolation regions therein and active regions therebetween. The trenches and the active regions therebetween extend into first and second device regions of the substrate. A sacrificial layer is formed in the trenches between the active regions in the first device region, and an insulating layer is formed to substantially fill the trenches between the active regions in the second device region. At least a portion of the sacrificial layer in the trenches in the first device region is selectively removed to define gap regions extending along the trenches between the active regions in the first device region, while substantially maintaining the insulating layer in the trenches between the active regions in the second device region. Related methods and devices are also discussed.

  • Patent number: 8642912
    Abstract: Disclosed is a vacuum circuit breaker. As a plurality of components of main circuit units are integrally formed as one module by molding using epoxy, the main circuit units are easily fabricated, and assembly errors are prevented. Since the main circuit units are arranged to be symmetrical to each other based on a driving unit, an insulation distance between a switchgear and the main circuit units can be obtained without increasing a size of the switchgear. This may allow the main circuit units to be easily arranged at the right side or at the left side according to an installation state of the switchgear.

  • Patent number: 8440930
    Abstract: Disclosed is a vacuum circuit breaker. A rotation link provided between a rotation shaft which transfers a rotation force of a driving force, and a moveable link which performs a linear motion by a rotation force of the rotation shaft is configured to receive a tensile force to be pulled to a direction of the rotation shaft when a driving unit performs a closing operation. This may prevent the moveable link from being buckled during a closing operation, and thus prevent lowering of the reliability due to deformation of sliding levers.

  • Publication number: 20120280034
    Abstract: An automatic teller machine (ATM) may temporarily stack paper mediums in a carriage, adjust an advancing direction of the carriage by rotating the carriage by a rotor, and dispense the paper mediums to one of a plurality of dispenser portions by the carriage moving along movement paths. In addition, since a discharge path for paper medium being discharged from a rejected medium transfer portion to a collected medium storage portion and a discharge path for paper medium being discharged from the carriage to the collected medium storage portion are formed in a common discharge space, paper mediums detected to be abnormal and rejected and paper mediums not received by the dispenser portions but retracted may be stored in one place. Consequently, the structure may be simplified.
