A conversion assembly for affixing a modern guideway to a manually operated machine tool guideway in a nondestructive manner. The conversion assembly mates to the existing machine tool guideway using surface tension via non-destructive compressive and/or tensile forces in order provide a suitable support surface upon which a modern guideway can be affixed.

Discussed is an apparatus for notching an electrode sheet, the apparatus including a transfer unit having first and second transfer rollers provided on a bottom surface of the electrode sheet to transfer the electrode sheet at regular intervals, a jig unit provided below the electrode sheet, and supporting the bottom surface of the non-coating portion and a notching unit provided above the electrode sheet to notch the non-coating portion supported on the jig unit to provide the electrode tab, wherein the jig unit includes a rotation member provided between the first and second transfer rollers and rotated in a direction perpendicular to a transfer direction of the electrode sheet, two or more jigs provided on an outer circumferential surface of the rotation member to alternately support the non-coating portion disposed between the first and second transfer rollers when the rotation member is rotated.

A ball screw mechanism includes a ball nut member that threadedly engages with a rack shaft via a plurality of balls, and a rolling bearing including an outer ring retained by a housing, an inner ring retained by the ball nut member, and a plurality of rolling elements. The ball screw mechanism moves the rack shaft in an axial direction relative to the housing through rotation of the ball nut member. A method for inspecting the ball screw mechanism includes fixing the outer ring to a fixing jig, pressing the rack shaft in the axial direction while restricting its rotation to rotate the ball nut member together with the inner ring relative to the outer ring, measuring an amount of a run-out of the rack shaft along with the rotation of the ball nut member, and determining whether the amount of the run-out satisfies a predetermined condition.
