First, a new method is presented for synthesizing the Watt six-link mechanism which has two prismatic and five revolute pairs as a force-displacement transformer, by applying the five precision-point method to the input-output relation in which the moment of the weights of the links except the pendulum is approximated as a constant, and attaching an additional weight to the pendulum, which corrects the error due to the mass of the links. Second, a self-indicating scale of the pendulum-type is composed of the synthesized mechanism so that the ratio of the range of the output displacement to the maximum length of the links is 0.335 and the maximum structural error is 1/15 400 and a linear-rotary motion trans-former using a rack and pinion whose axis is supported by two circular plates overlapped each other crosswise. Then the linearity of 1/1000 and the reproducibility of 1/4000 are confirmed experimentally.
