Abstract: A sheet conveying device includes a sheet stacker, an air blower, and a guide. The sheet stacker stacks sheets. The air blower blows air to the sheets. The guide faces an uppermost sheet on the sheet stacker. A set height of a contact portion of the guide to contact the uppermost sheet is changeable.

Abstract: A sheet stacking device includes a sheet stacker, a pair of sheet restrictors, and a stacking adaptor. The sheet stacker has a first sheet stacking face on which a bundle of sheets is stacked. The sheet stacker includes a leading end support to support a leading end of the bundle of sheets in a feeding direction by a second sheet stacking face and a pair of cutouts disposed upstream from the leading end support. The pair of sheet restrictors slide in the pair of cutouts in a width direction orthogonal to the feeding direction to regulate a position of the bundle of sheets. The stacking adaptor is detachably attached to the sheet stacker to cover the pair of cutouts. The stacking adaptor has a third sheet stacking face to support a portion of the bundle of sheets disposed at the pair of cutouts.

Abstract: A system for non-destructive non-contact quality inspection of dry electrode units of energy storage includes an eddy current-based inspection system having a conveyor belt, and a hollow dielectric shell. An outer surface of the shell has a plurality of spaced apart measuring transducers. Each of the transducers include a feed-through eddy current probe and at least two strap capacitors spatially linked therewith. In the related method, an electrode unit to be inspected is placed on the conveyor belt and enters and moves through the dielectric shell. The electrode unit is excited using a magnetic field from the eddy current probe as it passes by each of the plurality of transducers, where eddy currents at a plurality of frequencies are induced in the electrode unit. The modulation characteristics of impedance at a plurality of frequencies are measured by the probes, and from the impedance data it is determined whether the electrode unit is defective.

Abstract: A method and related apparatus for non-contact measurement of electrical conductivity of powder-like materials using eddy currents includes the steps of placing a powder to be measured in a hollow dielectric sampling container, the sampling container disposed and freely axially moving within an outer dielectric housing. An eddy-current sensor including a winding is arranged on an outside surface of the housing. Current is forced in the winding to excite the powder to generate eddy currents. The introduced active resistance is measured at the eddy-current sensor and an electrical conductivity of the powder is determined using the measured active resistance. The powder is preferably vibration compacted and the density and electrical conductivity determined at a plurality of stages during the vibration compacting step.
