A composite protective sheet material for covering a smooth surface of a transparent material, especially but not exclusively for covering the surface of a lens. It comprises a film substrate at least one main surface of which is covered by an adhesive coating. At least a part of the said at least one main surface of the substrate is free or substantially free of adhesive, or has less adhesive applied to it than does the rest of that surface, thereby to provide a finger lift region of the film at an edge of the surface covered thereby.

A conveying apparatus for a separator for a fuel cell includes: a conveying portion configured to hold an intermediate part of the separator and lift the separator; and restricting portions configured to restrict the opposite ends of the separator to warp the intermediate part of the separator in the lifting direction when the conveying portion lifts the separator. The restricting portions are configured to release the opposite ends when the intermediate part of the separator warps in the lifting direction with a target curvature amount.

This application discloses a cushioning pad and a cushioning apparatus. The cushioning pad includes a body and a positioning adsorption structure. The body is arranged to separate a display panel; and the positioning adsorption structure is arranged on a surface of the body for adsorption by a suction nozzle of a machine. An upper surface area of the positioning adsorption structure is greater than a vacuum adsorption area of the suction nozzle. An upper surface of the positioning adsorption structure corresponding to the suction nozzle is a smooth plane. There are at least two positioning adsorption structures, and the positioning adsorption structures are symmetrically distributed.

When on flat glass elements an anti-corrosion agent and a separation agent, containing a powdery anti-corrosion agent and a powdery separation agent, is applied with the anti-corrosion agent and the separation agent being jointly applied on at least one side of the flat glass elements, the partial quantities of the powdery separation agent and the powdery anti-corrosion agent can be dosed according to requirement without causing an excess of separation agent or a shortage of anti-corrosion agent by holding ready and dosing the said anti-corrosion agent and separation agent independently from each other and by blending them together only after dosing.

An article includes a substrate including two main faces defining two main surfaces separated by edges, the substrate bearing a functional coating deposited by magnetron sputtering deposited on at least one portion of one main surface, and a temporary protective layer deposited on at least one portion of the functional coating, wherein, the temporary protective layer is deposited directly in contact with the functional coating, the temporary protective layer has a thickness of at least 1 micrometer, the temporary protective layer is not soluble in water, and the temporary protective layer is obtained from a composition comprising (meth)acrylate compounds, the substrate bearing the functional coating has not undergone a heat treatment at a temperature above 400° C.

Provided is a method for producing a glass unit. The method comprises a step (A) of obtaining a glass plate comprising a glass substrate and a Low-E layer placed on the glass substrate; a step (B) of applying a protective sheet to the Low-E layer surface of the glass plate; an optional step (C) of subjecting the glass plate to at least one process selected from the group consisting of transportation, storage, processing, washing and handling; a step (D) of removing the protective sheet from the glass plate; and a step (E) of assembling a glass unit using the glass plate. The protective sheet comprises a waterproof layer, and a PSA layer provided to at least one face of the waterproof layer. The PSA layer has a surface hardness of 0.5 MPa or less.

A conveying device includes a flat plate member including a through-hole and a first conveying head that sucks a conveyance object via the through-hole in a state of holding the flat plate member and conveys the flat plate member and the conveyance object to an accommodation case. Moreover, the flat plate member has a shape that prevents an end of the conveyance object from abutting an inner side surface of the accommodation case during placement into the accommodation case.

The present disclosure provides a packaging assembly and a preparation method thereof, and a display device. The packaging assembly may include at least one of packaging unit; the at least one of packaging unit including a first inorganic layer, a second inorganic layer, and an organic layer sequentially stacked, wherein a material of the first inorganic layer and a material of the second inorganic layer are different. Holes inside the layers may be reduced, and a density of the layers may be increased. An effect of blocking the water vapor may be higher than that of a single layer, and a packaging effect may be better.

The present invention relates to a tool that is to be mounted on a handling device and grips pallet bases, the tool including a frame and a gripper for the bases that is mounted on the frame. The gripper is movable in the frame in such a way as to cooperate with a single edge of a pallet. The present invention relates to a corresponding transfer apparatus and a corresponding method.
