Title: Separating method for contour line of object
Inventor: IIJIMA GOHEI
IPC: G06T7/60
Filed: 1990-02-01
Abstract: PURPOSE:To reduce arithmetic processing time and to separate the contour line of an object by detecting a point at which the change of the curvature of the contour line is minimized as a recessed corner, and generating an auxiliary contour line between two recessed parts with the minimum distance out of the corner. CONSTITUTION:The contour line 42 is expressed in a chain code expressing the direction of travel, and curvature at each point comprising the contour line is found from an angle formed by front and rear line segments, and the points m44 and m45 at which the change of the curvature are minimized are detected as the recessed corners (that is recessed angle interval part). In such a way, the plural recessed corners 44, 45 are detected, and the recessed corners with the minimum distance are connected with, for example, the auxiliary contour line of straight line, and the images of the object being brought into contact with each other or being overlapped can be separated. Since arithmetic processing is performed by using only data on the contour line in such a way, the quantity of arithmetic processing can be reduced and the processing time can be shortened.

Title: Fluid enclosing-type vibro-isolating support body
Inventor: MIZUNO MUTSUO
IPC: B60K5/12
Filed: 1986-02-06
Abstract: PURPOSE:To improve vibration cutting off operation against a vibration with a small amplitude, by forming a pair of void spaces on both sides of an elastic member disposed between an inner cylinder metal fitting and an intermediate metal fitting. CONSTITUTION:The first elastic member 16 is disposed between an inner cylinder metal fitting 10 and an intermediate metal fitting 14. A pair of void spaces 30 are formed on both sides of this elastic member 16 facing each other as placing the inner cylinder metal fitting 10 inbetween. In the diametrical direction in which those void spaces are facing each other, the inner cylinder metal fitting 10 and the intermediate metal fitting 14 are to be in relative motion by shear deforming operation of the first elastic member 16. Therefore, as far as the relative motion is admitted, flexible spring character can be obtained in the facing direction of those void spaces. In other words, any vibration input in the facing direction of void spaces, is effectively absorbed by a shear deforming means of the first elastic member, when its amplitude is small. Meanwhile, when the amplitude exceeds the specified level, the inner cylinder metal fitting 10 touches the intermediate metal fitting 14, so that relatively rigid conventional spring character can be obtained by the second elastic member for forming a fluid chamber 20 communicated through an orifice member 26.
