An arithmetic device includes a deformation amount acquisition unit that acquires an actual measurement deformation amount of a fabrication object that is manufactured based on a target shape, the actual measurement deformation amount corresponding to a deviation amount of a shape of the fabrication object from the target shape, an analysis unit that performs an analysis, based on the target shape of the fabrication object and a reference inherent strain value corresponding to a reference value of an inherent strain of the fabrication object, and acquires an analytical deformation amount corresponding to a deviation amount of the shape of the fabrication object in the analysis from the target shape, and a strain calculation unit that calculates an estimated inherent strain value corresponding to an estimated value of the inherent strain of the fabrication object with the target shape, based on the actual measurement deformation amount and the analytical deformation amount.

A motor rotation irregularity detection circuit includes a first integrator for integrating a rotation detection signal that is output from a driver of a sensor-less motor; a differentiator for outputting a difference between a binary signal based on the integral in the first integrator and the rotation detection signal; a second integrator for integrating an output signal of the differentiator; a comparator for making a comparison between the integral in the second integrator and a reference voltage to output an irregularity detection signal; and an output terminal for outputting a signal coming from the comparator.

A riding lawn mower comprises a frame supported by wheels, a mower housing carried at the underside of the frame, a plurality of cutter blades located within the mower housing to cut grass, a collection bag mounted on the rear of the frame, a discharge chute extending between the mower housing and the collection bag and defining a clipping path from the cutter blades into the collection bag, a blower including an impeller housing attached to the mower housing and an impeller located within the impeller housing and cooperating with the butter blades to convey the grass clippings into the collection bag through the discharge chute. A short conduit connects the impeller housing to the upstream end of the discharge chute to conduct an air generated by the impeller into the discharge chute. A central axis of the conduit is offset downwardly from a central axis of the discharge chute.
