A casing of an aircraft turbomachine includes an annular shell extending around an axis A and made of a composite material having fibers that which are woven and embedded in a resin. An annular layer made of abradable material extends inside the shell, around axis A and is obtained by spreading and polymerizing a paste. Support panels extend around axis A and are interposed between the shell and the abradable layer.

The present technology relates to a shim for a die coater, a die coater including the shim, and a lithium secondary battery including a positive electrode manufactured using the die coater of the present invention, and according to the present technology, it is possible to smoothly apply slurry on the edge portion.

Provided is a coating die enabling coating of two layers of coating films stably. The coating die includes: a first block including a first manifold to receive a first coating liquid; a second block including a second manifold to receive a second coating liquid; and a shim sandwiched between the first block and the second block.

Provided is a slot die coater with a uniform flow of coating solution without stagnation. The slot die coater includes at least two die blocks; a shim plate provided between the two die blocks to form a slot; and a manifold provided in the die block and communicatively connected with the slot as a chamber in the shape of indention accommodating a coating solution, wherein the coating solution is discharged and applied to a surface of a continuously traveling substrate through a discharge port communicatively connected with the slot, and a ratio B/S of a manifold length B (mm) to a manifold cross-sectional area S (cm.sup.2) in a cross section along a traveling direction of the substrate is in a range of 1.9 to 9.8.

A surface chemical treatment apparatus provided with: a first conduit having an opening at one end and communicating with a liquid supply means at the other end; a second conduit having at one end an opening that surrounds the opening of the first conduit and communicating with a liquid suction means at the other end; and a moving mechanism for moving the openings of the first and second conduits relative to the solid phase surface, so as to make a surface chemical treatment possible in a fine pattern by allowing the patterning solution to be dispensed through the opening of the first conduit while allowing the solution to be suctioned up together with the surrounding liquid phase or gas phase medium through the opening of the second conduit that surrounds the opening of the first conduit and, thus, preventing seepage of the solution in all directions.

A process includes placing a mask over a substrate; delivering liquid film-forming compositions through the mask to the substrate; removing the mask to leave a multilayered raw shape on the substrate; and curing the multilayered raw shape to form the multilayered shaped film product disposed on the substrate. The mask has a delivery surface, an opposite surface and at least one aperture having a design corresponding to the desired shaped film product. The film-forming compositions are delivered through a multistream nozzle. The movement of the mask and the delivery of the first and second liquid film-forming compositions to the mask aperture are controlled to provide a volumetric flow rate of the first and second liquid film-forming compositions to the mask aperture corresponding to the volume of a void. The nozzle is in contact with the delivery surface of the mask.

A device for inspecting a die coater including a first die, a second die, and a shim formed between the first die and the second die, includes a rail formed to be fixed long on one surface of the first die in a longitudinal direction of the die coater, and at least one sensor assembly configured to move along the rail and inspect a lip or the shim of the die coater, wherein the sensor assembly includes a movable part moving along the rail in the longitudinal direction of the die coater, and a sensor module connected to the movable part, and configured to move in a thickness direction of the die coater and inspect the lip or the shim.

There is provided a multi-slot die coater in which a step is formed between rear surfaces of die blocks through a fixing block having a step portion. The fixing block has the step portion of a preset height, and any one die block is coupled to the step portion and the other die block is coupled to the other portion than the step portion, and thus the step is naturally formed between the rear surfaces of the die blocks by the coupling of the die blocks to the fixing block. Thus, it is possible to always maintain the distance of the front ends of the die blocks and the substrate, since the fixing block is fixed between the die blocks, once it is set, the coating gap does not change and is maintained during the process, thereby suppressing the widthwise coating gap deviation.
