Title: Endoscope with improved flexible insertion tube
Inventor: WU SU-SYIN
IPC: A61B1/005
Filed: 1997-11-28
Granted: 2000-08-01
Abstract: In a flexible endoscope having a flexible insertion tube comprising a tubular, biocompatible elastomeric outer covering thereabout which encloses an interior space, the improvement according to the present invention comprises a vapor  barrier between the outer covering and the interior space. Thus, vapor, such as hydrogen peroxide or other sterilants, passing through the outer covering from an atmosphere thereabout is prevented from entering the interior space by the vapor barrier. Further, the vapor is thus prevented from interacting with substances, such as lubricants, within the interior space to produce agents harmful to the elastomeric covering.

Title: Graphic processor and data processing system
Inventor: NAKAMURA ATSUSHI
IPC: G09G5/37
Filed: 1998-12-10
Granted: 2001-04-01
Abstract: The plotting control means 2 of a graphic processor 1 of the present invention weighted averages the pixel data of source image information arranged with the pixel data corresponding to arrangement of pixels with the pixel data adjacent in the direction orthogonally intersecting with the scanning direction. Thus, even when the difference between the image information of adjacent scanning lines is large, its difference is mitigated. At this time, the plotting control means may read out successively the pixel data from a memory in the direction orthogonally intersecting with the scanning direction and weighted average. It is unnecessary to increase the line buffer not only in the plotting control means but also in a display control means, and even when the blended processed image information is displayed by an interlace scan system, an unwanted flicker doesn't occur.
