  • Apparatus and method for analyzing an electric field or discharge in a transfer process
    Patent number: 8095347
    Abstract: An area in which a model of a soft medium is moved is divided into a plurality of elements. In response to an update of simulation time, parameters about the model of the soft medium are shifted to elements at a position to which the soft medium is to be conveyed. After the parameters are shifted, the shape of the model of the soft medium is calculated. The elements need not be redivided by shifting the parameters to the elements at the position, to which the soft medium is to be conveyed.
    Type: Grant

    Assignee: Canon Kabushiki Kaisha
    Inventors: Asako Sugiyama, Toyoshige Sasaki, Takuma Onishi
  • Analysis method, program for performing the method, and information processing apparatus
    Patent number: 7624001
    Abstract: An analysis method of analyzing a discharge phenomenon in an information processing apparatus having a memory includes calculating differences in potential between nodes on a first surface of a meshed simulation model and the corresponding nodes on a second surface thereof based on a predetermined amount of charge of each node before the discharge and the permittivity of each element of the simulation model; storing information concerning a pair of nodes having the difference in potential which exceeds a Paschen voltage determined from the distance between the nodes; and analyzing an amount of charge moved due to the discharge and electric potential distribution after the discharge based on the stored information and the amount of charge of each node before the discharge and storing the analyzed amount of charge and the electric potential distribution.
