    Abstract: A movable-body-speed-detecting apparatus includes a movable body capable of moving linearly and/or circularly, a plate fixed to the movable body, the plate having a predetermined length in a direction in which the movable body moves, and light emission/reception means arranged such that light output from a light-emitting element enters a light-receiving element. The plate has a window section that passes between the light-emitting element and the light-receiving element in accordance with movement of the movable body and that blocks or allows passage of light to the light-receiving element. The apparatus further comprises speed calculation means for calculating the speed of the movable body by converting the amount of light received by the light-receiving element into a signal and measuring the signal.

    Abstract: A motion transducer includes a rotatable wheel, a drive assembly that engages a movable rod in contact with the circumference of the rotatable wheel, and an encoder that measures the rotation of the rotatable wheel and that encodes information relating to the rotation of the rotatable wheel. Linear motion of the movable rod causes rotation of the rotatable wheel, the angular displacement of the rotatable wheel being proportional to the linear travel of the rod.

    Abstract: The turns of an optical fiber paid out from a canistor are counted, and the signature of the optical fiber is measured, by monitoring the electromagnetic field of the charge on the optical fiber as it moves past an antenna. The optical fiber follows a helical path as it is paid out. A stationary antenna located transversely proximate the payout region detects a periodic repeating variation of the bound and/or free electrical charge associated with the optical fiber, as the optical fiber periodically moves closer to and farther from the antenna along the helical path. Each period of the variation corresponds to one turn of optical fiber paid out from the canister.

    Abstract: A method of measuring feeding velocity of a web, on which a scale having pitches different from pitches of a mask are formed, is provided. The method includes: calculating a number of vibrations of a moiré image of light passing through the mask and the scale; calculating pitches of the scale of the fed web based on the calculated number of vibrations of the moiré image; averaging the pitches of the scale so that a change in a pitch between adjacent timings among the calculated pitches of the scale is minimized; extracting first signals corresponding to our phases for one pitch based on the averaged pitches of the scale; calculating two second signals for forming a Lissajous circle from the first signals; and calculating an angle of the Lissajous circle by the two second signals and then calculating the feeding velocity of the web by using the calculated angle.
