Abstract: An automobile run channel fitting device for fitting a run channel into an automobile door sash comprising a pair of robot arms 1 and 2 which act in harmony and a run channel fitting jig 3 attached to each robot arm, wherein the run channel fitting jig 3 comprises an upper roller unit 12 adapted to push the run channel to fit it into an upper sash, a rotatable lower roller 14 adapted to push the run channel to fit it into a lower sash, and a lower roller supporting means 15 adapted to support the lower roller 14 and insert the lower roller 14 into a gap formed between an inner panel and an outer panel. The lower roller supporting means 15 comprises a sliding mechanism 17, a bending section 18 and a roller supporting section 19.

Abstract: A duty correction circuit is provided which includes a level shifter receives complementary differential input signals having a duty ratio and controls levels of the differential input signals; a TrTf control circuit receives output signals of the level shifter and controls edge angles of the output signals; a waveform shaping circuit receives output signals of the TrTf control circuit and shapes waveforms of the output signals; a first common mode comparator extracts common modes of the output signals of the TrTf control circuit and compares the common modes; and a second common mode comparator extracts common modes of output signals of the waveform shaping circuit and compares the common modes. The level shifter controls the levels based on outputs of the first common mode comparator and the TrTf control circuit controls the edge angles based on outputs of the second common mode comparator.
