IPC: F16G5/16
Filed: 2000-01-07
Abstract: PROBLEM TO BE SOLVED: To warp the compression side cord part of a metal belt in an appropriate shape by suitably positioning contact parts where metal elements make contact with each other. SOLUTION: Contact surfaces TC, TL, TR through which a longitudinal pressing force is transmitted, are defined on the principal surface 40f of a metal element 32 at three positions, and the radial position of the centroid P of the contact surfaces TC, TL, TR is set between a line L1 at the thicknesswise center of a metal ring assembly 32 fitted in a ring slot 35 of the metal element 32, and a line L2 along the radially outer edge of the ring slot 35. With this arrangement, the compression side cord part of the metal belt is warped in a shape such that the cord part in particular becomes rectilinear or slightly curved outward, thereby it is possible to prolong the use life of the metal ring assembly 31, to reduce noise and vibration, and to enhance the power transmission efficiency.

Abstract: PROBLEM TO BE SOLVED: To resolve an occurrence of pulse hystersis during motor reversal which is a problem in position detection of an encoder using a conventional jitter removing circuit. SOLUTION: A signal processing circuit 3 of the encoder is a means removing jitters occurring before edges of rectangular wave signals of the encoder 2 outputting two phase rectangular wave signals with a mutual 90 deg. phase difference with respect to a displacement of a detected object 1.
