  • Publication number: 20080212114
    Abstract: An image processing apparatus for preventing unauthorized uses of image data by allowing the addition of a specific image in a black-and-white mode even when it is set that a specific image is added in a color mode. When a document is copied, a control section determines whether the apparatus is in a color mode or a black-and-white mode. When in a black-and-white mode, an adding condition determining section reads a set security level and a differential value and determines a security level lower than the one in a color mode. Based on the security level in a black-and-white mode, an adding condition of a specific image is determined. The specific image adding section adds a specific image different from the one in a color mode based on the adding condition. A black-and-white image added with the specific image is printed.

  • Patent number: 7420638
    Abstract: A method of fabricating a liquid crystal display device including vertical alignment layers formed on the substrates. The alignment layer having a polymer realizing vertical alignment is formed on the substrate an unpolarized ultraviolet light is then irradiated in the oblique direction at an angle not more than 45 degrees with respect to the surface of the alignment layer. The ultraviolet light has an exposure energy of 30 to 120 mJ/cm2 per percent of the polymer content realizing the vertical alignment of the alignment layer. The liquid crystal can thus align substantially vertically to the surface of the alignment layer, with a pretilt, and such an alignment is realized by the irradiation of the ultraviolet light, without rubbing.

  • Patent number: 7420697
    Abstract: A communication apparatus where transmission waiting time for an originating facsimile machine is shortened. A transmitter/receiver section of one of two communication control sections receives a transmission subscriber identification (TSI) signal from the originating facsimile machine.

  • Patent number: 7420701
    Abstract: Systems and methods for accurately recognizing a language format of an input imaging data stream when no explicit language switch is present. A sniffer process is initiated when an imaging device receives an input imaging data stream. The sniffer process analyzes an initial sample of the input stream to determine the language format by enumerating through a set of language recognizers that are implemented as callback functions. The enumeration uses a dynamic heuristic approach to selecting the order in which to try the language recognizers. Each language recognizer has a sample size associated with it. For each language recognizer enumerated, the sniffer process pre-reads the associated sample size and invokes the associated callback function with the byte sample. The enumeration continues until a language recognizer acknowledges recognition of the language format or the set of language recognizers is exhausted.
