摘要： A relative-position measuring system of a recording-medium library apparatus including first to third reference flags installed for measuring the magnitude of the gradient of an accessor and a plurality of relative-position flags provided at a cell drum. A flag sensor for detecting the first to third reference flags is installed on a hand mechanism of the accessor for finding the gradients of the accessor with respect to Y and Z axes. The gradients of the accessor with respect to Y and Z axes are used for correcting design tachometer count values of the relative-position flags to give theoretical tachometer count values which are stored in a memory unit. When the accessor is moved, the relative-position flags are sensed by the flag sensor. Actual tachometer count values which are actually obtained when the relative-position flags are detected by the flag sensor are also stored in the memory unit. Then, difference data between the theoretical tachometer count values and the actual tachometer count values is calculated and stored in the memory unit as well.

摘要： An asbolute position-measuring transducer system for an industrial robot having a plurality of axes of movement comprises an individual position transducer in the form of a resolver for each one of the axes, with the operating range of each axis corresponding to a plurality of revolutions of its resolver, a revolution counter connected to the output of the resolver of at least one of the axes for receiving the output signals from the resolver and counting the accumulated number of resolver revolutions, a back-up battery adapted for supplying the resolver and the revolution counter during the power failure, and a device for effecting the intermittent operation and reading-off of the resolver during the battery back-up operation, whereby a single resolver is used for position measuring during the normal operation and for counting revolutions during the battery back-up operation.

摘要： The device is intended to be used for recording the position reached by a moving part, such as the arm of an industrial robot moved by a rotary motor (M). The device comprises, in an assembly capable of being associated with the said moving part, an angular-position transducer such as a resolver (2), capable of generating at least one signal (4, 5) indicating the position reached by the motor (M) during a rotation, counting means (12) connected to the angular-position transducer (2), capable of storing a cumulative count of the signal generated by the transducer (2) itself and indicating the position reached by the moving part, and power supply means such as a buffer battery (18) capable of keeping the position transducer (2) and the counting means (12) active even when there is no external power supply.
