Discussed is an apparatus for notching an electrode sheet for an electrode tab, the apparatus including: a transfer unit including first and second transfer rollers to continuously transfer the electrode sheet at regular intervals; a jig unit disposed between the first and second transfer rollers, and supporting a non-coating portion of the electrode sheet; and a notching unit to notch the non-coating portion supported on the jig unit, 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; and two or more jigs provided on an outer circumferential surface of the rotation member to support the non-coating portion disposed between the first and second transfer rollers.

A die transfer method and a die transfer system thereof are disclosed. The die transfer method includes the following steps: providing a wafer to generate a plurality of dies; transferring a plurality of dies to a surface of a donor substrate to fix the plurality of dies on the surface of the donor substrate by a photoreactive adhesive layer; aligning the donor substrate with a target substrate, wherein the target substrate has a landing site and the position of at least one die corresponds to the position of the landing site; irradiating the donor substrate with a radiation beam to cause the photoreactive adhesive layer to drop the at least one die, such that the at least one die is transferred onto the landing site of the target substrate; and fixing the at least one die at the landing site.

An adjustable linear motion carriage assembly is configured to ride on a rail (34, 220) with generally parallel opposing faces in a linear motion of travel along the central axis of the rail. The carriage assembly includes at least one carriage member (32, 140, 160, 261) comprising a frame (40, 150, 170, 270) supporting a plurality of bearings (62). The carriage member can be used singularly or assembled together to provide control over desired degrees of freedom of the carriage assembly. The individual carriage member frames can flex by elastic displacement near the bearing location (122, 142, 162) to accommodate rails with minor variations in width.

A machine tool is equipped with a second supply pipe having elasticity and having one end side fixed to a spindle head and the other end side fixed to an arm portion, a cover provided within a machining area, and rollers. When the spindle head is moved in a direction to come close to the arm portion, the second supply pipe is bent and then a portion of the second supply pipe is brought into abutment against the cover. The rollers are provided at a portion of the cover against which the second supply pipe is brought into abutment, and are configured to reduce friction between the cover and the second supply pipe when the second supply pipe moves relative to the cover in an abutment state against the cover.

Pipe machining apparatuses and bearing assemblies are provided. In one aspect, a pipe machining apparatus includes a frame, a tool carrier, a first roller bearing and a second roller bearing. The tool carrier is coupled to and movable relative to the frame and defines a race therein. The first roller bearing includes a first shaft and a first roller rotatably coupled to the first shaft. The first roller is at least partially positioned in the race and is rotatable about a first roller bearing axis adapted to remain substantially fixed relative to the frame. The second roller bearing includes a second shaft and a second roller rotatably coupled to the second shaft. The second roller is at least partially positioned in the race and is rotatable about a second roller bearing axis. The second roller bearing is adjustable to move the second roller bearing axis relative to the frame.
