  • Publication number: 20080258177
    Abstract: Wirings connected to a gate electrode of a slave switch circuit cell for substrate bias circuits are respectively electrically connected to a wiring for a power supply potential and a wiring for a reference potential. Thus, the switch operation of the slave switch circuit cell is made invalid. Wirings connected to n wells of respective circuit cells are electrically connected to a wiring for the power supply potential, and wirings connected to p wells of the respective circuit cells are electrically connected to the wiring. Thus, the n wells are fixed to the power supply potential, and the p wells are fixed to the reference potential.

  • Publication number: 20080018963
    Abstract: An image data process apparatus includes a judgment unit and a selection unit. The judgment unit is configured to judge whether or not a directory in which image data is stored is compliant with a DCF standard. The selection unit is configured to select the image data stored in the directory if the directory that has been judged not to be compliant with the DCF standard by the judgment unit. A computer readable medium is encoded with an image data process computer program configured to implement a process of selecting image data that causes a computer to implement a method of selecting image data. Whether or not a directory in which image data is stored is compliant with the DCF standard is judged. The image data stored in the directory that has been judged not to be compliant with the DCF standard during the judging is selected.

  • Patent number: 7076394
    Abstract: A method for inspecting an object using a time delay integration sensor. A storage time of the time delay integration sensor is changed in response to a signal level of a signal outputted from the time delay integration sensor, and a scanning speed of a scan by the time delay integration sensor is changed in response to the signal level of the signal outputted from the time delay integration sensor. The object is then scanned using the time delay integration sensor to inspect the object under the changed storage time and the changed scanning speed.
