Abstract: An object of the present invention is to provide a method for non-invasively diagnosing invasiveness or degree of invasion of colorectal tumors. The present invention is characterized in that it enables to obtain a specimen that can be used to detect invasive colorectal tumors by spraying a washing fluid onto the colonic mucous layer of a subject to detach the mucus from the mucous layer, and collecting the detached mucus together with the washing fluid.

Abstract: A system having a relative coordinate input unit for inputting relative coordinates of an object to a viewer point, a data storage unit for storing plural pieces of data of attribute information (audio information, video information, etc.) of the object according to plural sets of relative coordinates corresponding to the viewer point, and a data preparing unit for reading out and delivering the data of attribute information on the object corresponding to the relative coordinates according to the inputted relative coordinates, in which the attribute information given by the object to the viewer point corresponding to the relative position of the object to the viewer point is presented in real time if the object moves very fast.

Abstract: A pattern recognition processing system in which variations in a character, pattern or the like, especially in a handwritten one, are suppressed to extract its invariable characteristics, ensuring accurate recognition of the character, pattern or the like. The pattern to be recognized is divided into circumscribed quadrangular areas and scanned in horizontal and vertical directions to extract reflection segments between the vertical frames of the circumscribed quadrangular areas and particular segments between adjacent ones of pattern strokes. Further, endpoints of these reflection and particular segments are checked in directions across the scanning directions to extract those endpoints which are not blocked by the pattern strokes, and the corresponding positions of the co-ordinates of these endpoints on a figure frame in the directions across the scanning directions are encoded to extract characteristics of contours of the pattern to be recognized.
