  • Publication number: 20090231601
    Abstract: An image processing apparatus is disclosed that includes an image processing part configured to perform image processing for causing a printer to print document data, the printer having a nozzle head having a first nozzle group and a second nozzle group, the first nozzle group having multiple K nozzles and multiple nozzles whose positions coincide with positions of the K nozzles in a sub scanning direction, the second nozzle group having multiple nozzles offset in the sub scanning direction from the K nozzles. The image processing part is configured to perform the image processing so that K is prevented from being applied to and one or more colors related to the second nozzle group are applied to multiple dots corresponding to the second nozzle group in a single movement of the nozzle head in a main scanning direction with respect to a gray drawing object contained in the document data.

  • Patent number: 7518675
    Abstract: A method of the present invention includes the steps of forming an organic material film having projections and depressions, using a photo-embossing material, on an insulating film on an underlying electrode in a thin-film transistor of an active-matrix liquid crystal display device; exposing the insulating film in a contact-hole-forming-area by reducing a thickness of the organic material film by a dry etching to said organic material film; forming a contact hole and exposing the underlying by a dry etching to the exposed insulating film; and contacting the exposed underlying electrode with a reflective electrode by forming the reflective electrode on the resulting structure.

  • Publication number: 20090041483
    Abstract: Upon generation of an image forming request, a control unit sets a request flag in a nonvolatile rewritable memory. A toner consumption monitoring unit calculates amount of toner consumption during a process of image formation based on the image forming request and the request flag. Upon completion of the process of image formation, the control unit deletes the request flag from the memory unit. Thus, it becomes possible to determine whether the amount of toner consumption is correctly updated based on the request flag and accurately monitor the amount of toner consumption.

  • Publication number: 20090021659
    Abstract: A source electrode and a drain electrode on a silicon oxide film (31) each has a double-layered structure of an ITO film (32), a transparent electrode, and a metal film (33) formed on the ITO film (32). A gap (35), no source electrode and drain electrode region, is formed between the source electrode and the drain electrode. A silicon nitride film (34) (a gate insulating film) is formed on the source electrode and the drain electrode and in the gap (35). The silicon nitride film (34) is a first region D1 having a relatively large thickness and a second region D2 having a relatively small thickness. The region D2 of the silicon nitride film (34) is provided with an MIM structure. A gate bus layer (36) is formed on the silicon nitride film (34). An MIM structure is formed in the second region D2.

  • Publication number: 20080232830
    Abstract: An image formation apparatus including a toner cartridge for holding toner, an image supporting unit, on which an electrostatic latent image corresponding to a toner image is formed, a toner development unit for developing the latent image into the toner image with the toner, a detecting unit for detecting toner concentration of the toner image, and a control unit for controlling an amount of toner adhering to the latent image by adjusting a development bias voltage based on an output of the detecting unit. If control by the control unit based on the detection output of the detecting unit is insufficient, and consumption of the toner is out of a predetermined normal range, the control is carried out by estimating one of toner consumption amount and toner recovery amount in a direction that departs from the predetermined normal range.

  • Patent number: 7321418
    Abstract: A stage apparatus includes a base, a stage movable on the base in first and second directions, a first member movable relative to the base in the first direction, and a second member movable relative to the base in the second direction. The first member is placed on the second member. With this arrangement, drive reaction-forces generated due to movement of the stage can be canceled by moving the first and second members, resulting in a smaller space needed for accommodating a canceling mechanism.

  • Publication number: 20070093416
    Abstract: The present invention provides a human ?-defensin secretion promoter that can be used in various forms, such as external preparation, internal preparation, food, etc., and promotes human ?-defensin secretion. An organic acid has an effect of promoting the secretion of human ?-defensin, particularly human ?-defensin-2, and therefore the organic acid is used as an active ingredient of a human ?-defensin secretion promoter. Furthermore, by adding the human ?-defensin secretion promoter to external preparations, internal preparations, or foods, a human ?-defensin secretion promotion effect can be imparted thereto.
