  • Publication number: 20220171908
    Abstract: There is an on-site process as at least part of an OT-side process. The on-site process includes one or more tasks that start and finish for each of one or more targets. A pseudo model that simulates such an on-site process is prepared. A support system executes the pseudo model, and executes an IT-side process, based on pseudo execution data that is data obtained by executing the pseudo model.

  • Patent number: 11112779
    Abstract: A facility that includes machines, includes a camera generating facility operation data, which includes an image of any given space. A computer system comprises: a data obtaining module obtaining the facility operation data; a work identification module identifying work that is performed in the facility, based on the image included in the facility operation data; and an output module outputting time-series information indicating a flow of the work. The work identification module identifies an object included in the image; identifies the work based on information about the identified object; and generates work analysis data, which associates the identified work, a period in which the identified work has been performed, and machines that is related to the identified work with one another. The output module outputs the time-series information or statistical information by using the work analysis data.

  • Patent number: 7719310
    Abstract: A circuit for attaining reduction in AC noise on power supply line caused by IR drop upon use of a decoupling capacitor represented by a cross-coupled decoupling capacitor with enhanced resistance to electrostatic breakdown, required in the case of a process of a high technology. There is also provided a circuit for suppressing the AC noise on power supply line due to resonance. MOS transistors composing the cross-coupled decoupling capacitor with enhanced resistance to electrostatic breakdown are caused to have lower threshold voltages Vth, thereby reducing a resistance between a source and a drain of each of the MOS transistors, resulting in reduction in IR drop. Further, a damping resistance is effective for suppressing the AC noise on power supply line, and the source-to-drain resistance of each of the MOS transistors is utilized as the damping resistance.
