Abstract: PROBLEM TO BE SOLVED: To prevent the large play of a handle by the loosening of an inner cable by providing elastically pressing members for elastically pressing the exposed parts of two inner cables in mutually opposed directions on both sides of a casing, and pressing the inner cables, even if loosened, to impart a proper tension thereto. SOLUTION: Outer tubes 5 are removed by a fixed length in the middle parts of two control cables 4, 4, and the end parts are fixed to a casing 30 to juxtapose the exposed parts of two inner cables 6, 6 in parallel within the casing 30. Since the inner cables 6, 6 are elastically pressed in mutually opposed directions by guide bodies 33, 33, the inner cable 6 on the side likely to loosen is pressed to impart a tension thereto. The tension is regulated by screwing quantity of regulating screws 31, 31. Consequently, even if the inner cable 6 is loosened by the wear of the liner of the outer tube 5 or the elongation of the inner cable 6, a proper tension can be regularly imparted to hold the play of a handle 1 at a proper value.

Abstract: PURPOSE:To enable highly accurate measurement by obtaining equations of (n) tangents drawn from projection centers of a right and a left cameras to tangent planes of a cylinder, operating an approximate point of a center of the cylinder and calculating arm evaluation function for an area in the vicinity of the approximate point. CONSTITUTION:Projection points on an image surface at the boundary of a cylinder are detected thereby to detect tangent planes of the cylinder. Equations of tangents F1 L1, F2 L2,... drawn from projection centers F1, F2,... of a right and a left cameras for obtaining a stereo image to the tangent planes of the cylinder are determined. A center C of the cylinder is operated based on the obtained equations as an approximate point of a true center of the cylinder. Then, based on the equations of tangents, a square sum of differences between lengths of perpendiculars CL1, CL2,... from coordinates of the virtual center C of the cylinder to the tangents and an average value of the perpendiculars is used as an evaluation function E, and coordinates of an approximate area of the center C are substituted into coordinates of the virtual center C of the cylinder to obtain coordinates where the evaluation function E becomes minimum. The obtained coordinates represent a position of the center of the cylinder. The average length of the perpendiculars to the tangents is a radius of the cylinder.
