  • Shock Absorbing Device For Passenger Conveyors
    Publication number: 20080087522
    Abstract: A shock-absorbing device for passenger conveyors comprises shock-absorbing members, which are attached respectively to at least one side of each of an inner rail and an outer rail of a track and protrude from the inner and outer rails toward a step roller. Supporting members are attached to the shock-absorbing members for supporting the shock-absorbing members together with the inner rail and the outer rail.

  • Circuit of redundancy IO fuse in semiconductor device
    Publication number: 20050073353
    Abstract: Provided is related to a redundancy IO fuse circuit of a semiconductor device. The redundancy IO fuse circuit is advantageous to enhancing an overall processing speed of a redundancy operation by preventing a voltage drop by a threshold voltage due to an NMOS transistor, by reducing back bias effects, preventing a decrease of noise margins at an inverter connected to an IO bus, and by improving time delay property involved in current reduction according to variation of operation mode.
