Stage structure in a bonding machine including a plate movably fitted in a bonding chamber, a plurality of blocks of electro-static chucks fitted to the plate for providing an electro-static force to hold a substrate, a plurality of vacuum holes in the plate around the electro-static chucks for receiving a vacuum force, and adsorbing and holding the substrate, and a plurality of alignment mark confirming holes in a periphery of the plate for confirming the marks for aligning the adsorbed substrate, thereby separating substrate from the stage more easily by applying a DC power with polarities opposite to a regular DC power.

It is possible to obtain a disk substrate in which an edge of a center hole is free of flash. The disk substrate (23) in which the center hole (24) is provided with a straight portion (24a) and a tapered portion (24b), and an edge on the side of a signal transfer surface (22) of the tapered portion (24b) is provided with an R surface or C surface (24c), a mold apparatus optimum for molding the disk substrate (23), and a disk taking-out apparatus.

An LCD panel including a first substrate, a second substrate and a smectic liquid crystal layer is disclosed. The first substrate includes a first electrode, a second electrode and a first horizontal alignment film. The first electrode has plural first portions. The second electrode has plural second portions. The first portions are spaced by the second portions. The electrical field directions formed between the first portions and the second portions are perpendicular to the surface of the first substrate. The electrical field direction on each first portion is opposite to that on each second portion. The first horizontal alignment film covers the first and the second electrodes. The second substrate includes a second horizontal alignment film. The horizontal rubbing direction of the first horizontal alignment film is parallel to that of the second horizontal alignment film. The smectic liquid crystal layer is sealed between the first and the second substrates.

A printing medium feeding apparatus includes a feeding part which feeds a printing medium, and a printing medium aligning roller part which aligns a leading edge of the printing medium fed from the feeding part and transfers the aligned printing medium to an image forming part which forms an image on the printing medium, wherein the printing medium aligning roller part comprises a pair of rollers which transfer the printing medium to the image forming part, and an aligning shutter which is rotationally coupled to at least one of the pair of rollers, which rotates when the leading edge of the printing medium contacts the aligning shutter with a pressure greater than a reference pressure in a reference direction and guides the leading edge of the printing medium fed from the feeding part toward the reference direction.

A powder compacting apparatus (1) has a top plate (3), a die plate (9) and a bottom plate (12), combined with each other as follows. The top plate (3) holds upper punches (4) in place by punch holders (5), and the die plate (9) firmly grips a die holder (8) holding dies (7). The bottom plate (12) keeps lower punches (11) in place gripped by clamps (32) so that an amount of powder fed into each die (7) is compacted to give a consolidated powder piece. The die plate (9) is composed of an upper part (9a) and a lower part (9b) so that the die holder (8) is sandwiched by and between the parts (9a, 9b), in such a manner that these parts cooperate with each other to secure each die (7) in position.

The present invention relates to an electrode assembly including a multi-tab in which tabs are capable of being aligned and a method for manufacturing the same.The method for manufacturing an electrode assembly according to the present invention includes a stacking step of repeatedly stacking a negative electrode, a separator, and a positive electrode so that the separator is stacked between the negative electrode including an electrode tab and the positive electrode including an electrode tab to form an electrode stack, an electrode tab coupling step of coupling the electrode tabs having at least two or more same polarities of the electrode tabs of the electrode stack to each other, and a winding step of winding the electrode stack.
