    摘要: The present invention provides a method of cutting a workpiece efficiently with high accuracy by utilizing tension adjusters to approximate tension in a wire in a wire saw to a predetermined target tension while effectively reducing only tension in a winder-side wire. The method comprises a forward-driven cutting step of cutting a workpiece while moving a wire forward, a first switching step of reversing a driving direction of the wire, a backward-driven cutting step of cutting the workpiece while moving the wire backward, and a second switching step of reversing a driving direction of the wire and returning to the forward-driven cutting step, the steps being repeated in this order. In both switching steps, only tension in a winder-side wire is reduced by tension manipulators. A reduction in target wire tension therefor is performed after completion of deceleration of the wire in each switching step.

    摘要: The present invention provides a wire saw which cuts a workpiece using a cutting wire and is capable of adjusting wire tension with high responsiveness. The wire saw includes first and second workpiece cutting units 1A and 1B. Each of the workpiece cutting units 1A and 1B includes a pair of guide rollers 10a and 10b around which a wire W is wound to form a workpiece-cutting wire group. The wire saw further includes a tension detector 18 which detects tension in the wire W between the workpiece cutting units 1A and 1B, and a control device 50. The control device 50 changes a rotational speed of the guide rollers 10a and 10b of at least one of the workpiece cutting units based on the tension detected by the tension detector 18 so as to keep the tension within an acceptable range.

    摘要: A spectrophotometer 10 includes built-in detector 24 and external detector 32. When a mountable/removable optical path switcher 23a is installed in a specimen chamber 23, measurement based on detection signals from built-in detector 24 is replaced by measurement based on detection signals from external detector 32. The spectrophotometer further includes a measurement data threshold-value storage unit 51 that stores threshold value T for measurement data from built-in detector 24 or external detector 32, and a light-receiving detector recognition unit 52 that recognizes which detector is able to receive the measuring light beam based on the results of a comparison between threshold value T and measurement data from built-in detector 24 or external detector 32 while the measuring light beam is being introduced into specimen chamber 23.
