A slot coating die for applying a fluid composition on a substrate, comprising: an upstream die part having a lower edge; a downstream die part having a lower edge, the downstream die part facing the upstream die part and spaced apart from the upstream die part, and the lower edge of the upstream die part being vertically aligned with the lower edge of the downstream die part; a patterned shim plate between the upstream die part and the downstream die part, the patterned shim plate having a lower edge, wherein the lower edge comprises at least one cut-out; and a blank shim plate having a lower edge being devoid of cut-out, the blank shim plate being located between the downstream die part and the patterned shim plate; wherein at least one of the upstream die part and the downstream die part comprises at least one fluid inlet.

A coated film having good characteristics is manufactured. A method for manufacturing the coated film includes: (a) a step of applying a coating liquid 20a to a first surface of a base material 1 unwound from an unwinding unit UW; (b) a step of forming a coating layer 3b on the first surface of the base material 1 by drying the coating liquid (coating film 3a) on the base material 1; and (c) a step of winding the base material 1 on which the coating layer 3b has been formed in a winding unit WD. Also, the base material 1 is continuously arranged from the unwinding unit UW to the winding unit WD, tension cut of the base material 1 is performed by a first suction roll SR after the base material 1 is taken out from the unwinding unit UW and before the step (b), and tension cut of the base material 1 on which the coating layer 3b has been formed is performed by a second suction roll SR before the step (c).

[Problem] Upon application or film formation of a particulate matter to/on an object, the particulate matter moving with a speed is heated in a time duration from a suction port for particulate matter to the object, thereby softening or melting at least some of the particulate matter when the particulate matter is applied to the object.

[Solution] A particulate matter is heated by means of induction heating or laser in a time duration from a suction port for particulate matter to an object, so that at least some of the particulate matter is softened or melted at a relatively low temperature on the object in synergy with the collision energy of the particulate matter with the object, thereby enabling the application or film formation of the particulate matter.

A simplified switchable object and methods of making same are provided. The methods may include steps of applying a switchable material on a first surface of a first substrate, the switchable material having a thickness and a shape; applying a barrier material on the first substrate, circumferential to the switchable material; and applying a second substrate over top of, and in contact with, the switchable material and the barrier material, the first substrate, second substrate and barrier material defining a closed chamber encapsulating the switchable material. The methods may further include a step of applying a seal material.
