A synthetic nonwoven fabric having bonded fibers forming channels surrounding unbonded fibers forming raised slip resistant spots. The fabric is made by extruding hot polymer through a spinneret die onto a moving belt to form a sheet of random fibers, which sheet undergoes a calendering process between a pair of heated rollers, one of which rollers having a plurality of cavities defined in its surface. The resulting fabric can be laminated and otherwise combined with other layers as desired to provide an end product having good slip resistant properties.

A multilayer plate with composite material and a method thereof are described. The multilayer plate includes an aluminum-based thin sheet and a composite material layer. The aluminum-based thin sheet includes a first passivation layer, an aluminum-based metal layer, and a second passivation layer sequentially. The aluminum-based thin sheet includes a first surface and a second surface opposite to the first surface. The first and second surfaces are set with micro holes. A diameter of the micro holes in the second surface is ranging from 0.5 μm to 10 μm. The composite material layer includes a thermoplastic polymer and a fiber material. The composite material layer has a third surface and a fourth surface opposite each other. The second surface is adjacent to or connected to the third surface. At least one portion of the thermoplastic polymer fills into the micro holes in the second surface.

A layer transfer device includes a housing main body having an opening, a cover movable between an open position in which the opening is open and a closed position in which the opening is closed, a heating member provided in the housing main body and configured to heat a multilayer film and a sheet, a pressure member provided on the cover and configured to nip the multilayer film and a sheet laid on the multilayer film between the heating member and the pressure member, and a shutter movable between a protecting position in which the heating member is covered with the shutter, and a retreated position in which the shutter is away from the protecting position. The shutter is in the protecting position when the cover is in the open position.

Disclosed is a writing board attached to a surface for receiving notes or instructions from a user. The writing board includes vinyl foam, a flexible coating, and an adhesive layer. The writing board further includes a second temporary backing film. The vinyl foam includes a top surface and a microscopic cavernous surface. The flexible coating is coated on one of the microscopic cavernous surface to render the vinyl foam air-tight. The temporary backing film covers the microscopic cavernous surface coated with the flexible coating. A user peels off the temporary backing film to firmly attach the vinyl foam to the surface. The erase film is attached to the top surface of the vinyl foam. The erase film allows the user to write and erase content. The adhesive layer attaches the erase film to the top surface of the vinyl foam.

A layer transfer device includes a supply reel, a take-up reel, a driving source, a releasable restraining device, a heating roller, a pressure roller, and a controller. The driving source drives the take-up reel. The releasable restraining device is capable of switching to a restraining state in which a multilayer film is put under restraint in being drawn out from the supply reel and to a release state in which the restraint is lifted. The controller is configured such that when the driving source is generating the mechanical power, the releasable restraining device is in the restraining state if an image area in which an image is formed on the sheet is not present in a layer transfer position between the heating roller and the pressure roller, and the releasable restraining device is in the release state if the image area is present in the layer transfer position.

A display module manufacturing apparatus includes a stage on which a display module is disposed, a heater disposed on the stage, and configured to heat a first area of the display module, and wherein the heater includes a plurality of side surfaces and a contact surface, and a first bump controller detachably coupled to one side surface among the plurality of side surfaces and including a first bottom surface facing an upper surface of the stage. The contact surface is closer to the upper surface of the stage than the first bottom surface.

An embodiment relates to a multilayer graphite sheet with excellent electromagnetic shielding capability and thermal conductivity, and a manufacturing method therefor, wherein the multilayer graphite sheet has a multilayer structure of five or more layers in total and can be manufactured to have a thick thickness of 70 μm or more such that the electromagnetic shielding capability can be significantly improved. In addition, the multilayer graphite sheet is manufactured by graphitizing a hybrid laminate in which heterogeneous materials are mixed such that thermal conductivity and electromagnetic shielding capability can be simultaneously realized at a lower cost, thereby being useful as a thick film sheet which used in various applications such as home appliances and electric vehicles.

Provided is a low-density clad steel sheet having excellent formability and fatigue properties, including a base material; and cladding materials provided on both side surfaces of the base material, wherein the base material is a lightweight steel sheet including, by weight, C: 0.3 to 1.0%, Mn: 4.0 to 16.0%, Al: 4.5 to 9.0%, and a remainder of Fe and inevitable impurities, and each of the cladding materials is martensitic carbon steel including, by weight, C: 0.1 to 0.45%, Mn: 1.0 to 3.0%, and a remainder of Fe and inevitable impurities.

A method for manufacturing a sheet laminate to be affixed to an adherent surface of an object, the method comprising preparing a sheet member having a front surface to become a design surface and a rear surface on which an adhesive part has been formed, bending an edge part of the sheet member by sandwiching the sheet member from a front surface side and a rear surface side in a mold, and heating a part of a bent sheet member. The sheet laminate has a flat part spreading out in a flat plate shape, a side surface on which the edge part bent by the bending step is configured, and a connecting surface protruding and curving toward the front surface side between the flat part and the side surface, and in the heating step, the connecting surface is partially heated after the side surface is molded in the bending step.
