Patent number: 6585354Abstract: An image printing apparatus and method capable of preventing any smearing that occurs in printing at the same landing position using nozzles of different colors with a smaller RAM capacity are provided. For this purpose, for example, to prevent any ink smearing that occurs when K (black) ink and color ink are printed at the same landing point, K data in raster data transferred in accordance with the order of drive of the printing elements of a printing head is temporarily stored. In printing color data on the same raster, it is determined whether color data to be printed at the same landing point as that of the K data in the temporary storage area is present. If such data is present, smearing preventing processing is performed. In this way, any smearing between the K (black) ink and color ink can be prevented.Type: GrantFiled: February 28, 2002Date of Patent: July 1, 2003Assignee: Canon Kabushiki KaishaInventor: Tsuyoshi Otani

Patent number: 6504139Abstract: A substrate for a photoelectric conversion device that is effective in trapping light in a photovoltaic layer and can be manufactured by industrial mass-production, a method of manufacturing the same, and a photoelectric conversion device using the same. On a glass sheet containing an alkaline component, a first undercoating film containing tin oxide as a main component, a second undercoating film, and a conductive film containing tin oxide as a main component are formed in this order, thus obtaining a substrate.

Patent number: 6380480Abstract: A transparent substrate, a transparent conductive film, photoelectric conversion units, and a back electrode are stacked sequentially from a side on which light is incident. Further, intermediate films are formed between the transparent substrate and the transparent conductive film. The intermediate films are formed so that the relationship of R1<R2×0.8 is satisfied, wherein R1 represents an average reflectance in a wavelength region between (&lgr;−50) nm and (&lgr;+50) nm, where &lgr; (nm) represents a wavelength of the light allowing the photoelectric conversion units to have an optimal spectral sensitivity characteristic, and R2 denotes an average reflectance, in the wavelength region, of the photoelectric conversion device that does not include the intermediate film. In a tandem-type device including plural photoelectric conversion units, intermediate films are formed so that the average reflectance in the wavelength range is decreased in each photoelectric conversion unit.Type: GrantFiled: May 17, 2000Date of Patent: April 30, 2002Assignees: Nippon Sheet Glass Co., Ltd, Kaneka CorporationInventors: Hodaka Norimatsu, Masahiro Hirata, Akira Fujisawa, Tsuyoshi Otani, Yukio Sueyoshi
