  • Publication number: 20060221535
    Abstract: An electronic apparatus with an electrostatic discharging structure is disclosed. The electronic apparatus includes a key cap, a switch component, a discharging conductor, a grounding point and a circuit board. The switch component is mounted on the circuit board. The key cap is installed on the switch component. The grounding point is used to make contact with the ground of the electronic apparatus and is formed on the circuit board. The discharging conductor extends from a side of the key cap. When the key cap is pressed by a user, a part of the discharging conductor approaches or makes contact with the grounding point.

  • Patent number: 6846063
    Abstract: An ink jet printer includes a printhead and a maintenance station. The maintenance station includes a fixed support housing, a sled and a chimney. The sled is supported on the support housing and is movable relative to the support housing in both a horizontal direction and a vertical direction. The chimney receives ink spit from the printhead. The chimney has a fixed vertical position relative to the printhead and is horizontally movable in response to movement of the sled.

  • Patent number: 6775584
    Abstract: A new software support package is provided that monitors tool status and scheduling requirements in a semiconductor manufacturing environment. A multiplicity of tools interfaces with a Manufacturing Execution system (MES) that is a functional component of the Operation and supervision integrated MES user Interface (OMI). A User Interface (UI) function, which is also part of the OMI, interfaces between a multiplicity of users (of the OMI functions) and the MES sub-component of the OMI system.

  • Patent number: 6698855
    Abstract: An automatic spacing adjustment mechanism of cartridge, which utilizes an existing paper feed drive motor of a printer to adjust the distance from a cartridge of a print cartridge receiving seat of the printer to papers. The automatic spacing adjustment mechanism of cartridge includes a gear set and a lift unit. The gear set can be triggered to be in a mutual engaged state through motion of the print cartridge receiving seat to the utmost side. The gear set can be driven to rotate by the paper feed drive motor. The lift unit can be driven by the mutual engaged gear set to lift or lower the print cartridge receiving seat.

  • Patent number: 6263253
    Abstract: The present invention discloses an allocation method for establishing a theoretical dispatching model for dynamically allocating the bottleneck resource according to the on-line current data. At first, the on-line current data are obtained from the bottleneck resource and those tools next to the bottleneck resource. Decision parameters such as the remaining processing time, buffer WIP of the tools next to bottleneck resource are sequentially derived by using the current data. Each tool next to the bottleneck resource is then determined to receive additional lots from the bottleneck resource or not. Finally, the bottleneck resource is reallocated to those tools that requires the lots from the bottleneck resource.
