  • Publication number: 20060087675
    Abstract: When a print processing apparatus is in a power saving mode, an information processing apparatus informs, for the print processing apparatus, the user that the print processing apparatus is in the power saving state. It can thus be made known to the user that the print processing apparatus is in the power saving state.

  • Publication number: 20050275342
    Abstract: An organic EL display is displayed. The display is manufactured sealing and joining an organic light emitter constituted from thin film transistors, anodes, a light-emitting layer, a cathode and a protective layer which are laminated on a substrate, together with a laminated body of color filters and a black mask formed on a transparent substrate. The organic EL light-emitting layer is aligned with the color filters during the process of sealing the substrate and the transparent substrate using an outer periphery sealing layer and an internal sealing layer. The outer periphery sealing layer provides precise alignment between the organic EL light-emitting layer and the color filters and rapid fixing between them can be carried out, and prevents infiltration of moisture from the outside environment. The internal sealing layer prevents reflection of light from the organic EL light-emitting layer, and hence the light can be transmitted to the color filters effectively.

  • Publication number: 20050157554
    Abstract: An information processing apparatus includes a non-volatile memory including a first block where data error does not occur and a second block where data error is possible to occur. The first block stores a loader program, and the second block stores an apparatus controlling program. The loader program is executed to write the apparatus controlling program stored in the second block to a volatile memory, and the apparatus controlling program is executed on the volatile memory. Thus, the information processing apparatus can be provided at a reduced cost, using a NAND flash memory, which is inexpensive, to store a program.

  • Patent number: 6897087
    Abstract: An organic EL display device includes an organic EL light emitting element having the first electrode, an organic EL layer and the second electrode formed on a substrate; and a color conversion filter bonded to the organic EL light emitting element and having a color conversion filter layer formed on a transparent substrate. An outer sealing wall and an internal filling portion are formed between the organic EL light emitting element and the color conversion filter. A partition wall is formed between the outer sealing wall and the internal filling portion.

  • Patent number: 5912990
    Abstract: An image generation method and an image generation apparatus can execute conversion from edge addresses into dot patterns at a high speed and a low cost. A comparator compares predetermined upper-digit bits of input edge-address information indicating the position of a word of a dot pattern to be output with the value of a word counter for counting the number of words of dot patterns which have been output, and determines if an edge position indicated by the input edge-address information is present within the word currently being processed. A decoder detects the edge position within the word based on predetermined lower-digit bits of the input edge-address information. The detected edge position within the word is held within a flip-flop circuit.
