  • Patent number: 6583896
    Abstract: A low cost image reading apparatus and an image reading method is obtained which allows a high speed image reading process to be performed. When a frame image recorded on a negative film is read, the amount of light of a lamp and the charge accumulation time of a CCD area sensor provided in the prescan section of a film image reading apparatus are fixed. An image buffer is also provided for holding the density values data (the image data) obtained by the fine scan section until the auto setup processing and positive image examination, which are based on the density values data, are completed.

  • Patent number: 6561608
    Abstract: An image forming method and apparatus for ejecting plural inks having different densities and/or colors from an ink ejection port while changing a mixture proportion of the plural inks based on an image signal. The ejected plural inks are transported to a moving image receiving medium such as print paper to form an image. A quantity of flow of the respective ink is controlled in such a manner that a total ejected volume flow rate of the plural inks is always maintained constant. The condition for transporting the ink liquid consisting of plural inks led to the image receiving medium is satisfied, and the smooth and highly-accurate transportation is enabled, thereby the image quality can be improved. The ejected plural inks may be transported from the ink ejection port as a continuous fluid flow to the image receiving medium, i.e., the continuous coating mode.

  • Patent number: 6467893
    Abstract: An image forming method and apparatus for forming an image on an image receiving medium with plural coating liquids. A plurality of types of coating liquid are combined to form a recording liquid and extruded as a continuous flow from an array of plural extruding ports which are aligned in a direction substantially orthogonal to a relative movement direction of the image receiving medium. While a mixing ratio of the plural coating liquids is varied based on an image signal, the recording liquid is continuously applied on the image receiving medium to form the image thereon. The high-speed image formation is enabled with a reduced amount of ink to be wasted. Preferably, the plurality of types of the coating liquid are not equally mixed but can be superimposed in the form of a layer in the coating thickness direction to be continuously applied.

  • Patent number: 6299286
    Abstract: A recording liquid which is obtained by changing a proportion of mixture of image forming liquid and clear liquid based on an image signal is transported as a continuous flow to an image receiving medium to form an image. An undercoating liquid is superimposed on the recording liquid at the position where the recording liquid meets the image receiving medium to form a bead so that the recording liquid is loaded on the undercoating liquid. The stream line of the undercoating liquid is bent toward the upstream side in the bead and then turned back toward the downstream side to be straightened. Accordingly, the recording liquid superimposed on the straightened undercoating liquid becomes a stable straightened flow without a sinuosity. The generation of a sinuosity of a stream line of the recording liquid is prevented to improve the image quality. Preferably, a supply amount of the undercoating liquid is set constant.

  • Patent number: 5096828
    Abstract: A biochemical analysis method comprises the steps of accommodating a long test film in a refrigerator, repeatedly pulling the long test film out of the refrigerator until a sample-applying portion, i.e., the next unused portion of the test film, is aligned with a sample applying position, applying a liquid samples onto the sample-applying portions of the long test film at which time the sample-applying portions become sample-applied portions, incubating the sample-applied portions, and irradiating light to the sample-applied portions in order to determine optical densities, which depend on the how much of a certain constituent in a liquid sample existed and therefore reacted with a reagent in a reagent layer of the test film. The length of a sample-applying portion to which a present sample will be applied, is changed in accordance with conditions which exist after the analysis of the sample applied to the test film immediately prior to the present sample has been finished.
