  • Patent number: 11999024
    Abstract: The present invention provides technology with which it is possible to highly accurately assess the quality of fastening of a screw. The present invention comprises a position acquisition unit (13) that acquires the axial-direction position of a driver (50), and a fault assessment unit (14) that assesses that a fault has occurred in fastening of a screw when the amount of change in the axial-direction position of the driver (50) from when temporary seating occurred is greater than a threshold value. The present invention provides a technology with which the quality of screw fastening can be assessed with high precision.

  • Patent number: 10734374
    Abstract: An area of a semiconductor device having a FINFET can be reduced. The drain regions of an n-channel FINFET and a p-channel FINFET are extracted by two second local interconnects from a second Y gird between a gate electrode and a dummy gate adjacent thereto, to a third Y grid adjacent to the second Y gird. These second local interconnects are connected by a first local interconnect extending in the X direction in the third Y grid. According to such a cell layout, although the number of grids is increased by one because of the arrangement of the first local interconnect, the length in the X direction can be reduced. As a result, the cell area of the unit cell can be reduced while a space between the first and second local interconnects is secured.

  • Publication number: 20130016829
    Abstract: There is provided a highly secure cryptographic processing apparatus and method where an analysis difficulty is increased. In a Feistel type common key block encrypting process in which an SPN type F function having a nonlinear conversion section and a linear conversion section is repeatedly executed a plurality of rounds. The linear conversion process of an F function corresponding to each of the plurality of rounds is performed as a linear conversion process which employs an MDS (Maximum Distance Separable) matrix, and a linear conversion process is carried out which employs a different MDS matrix at least at each of consecutive odd number rounds and consecutive even number rounds. This structure makes it possible to increase the minimum number (a robustness index against a differential attack in common key block encryption) of the active S box in the entire encrypting function.
