A fan blade having an opening on one side exposing one or more cavities, and a composite cover that fits over the opening, is provided. The composite cover has a variable thickness resulting from the layering of cover plies having different shapes, and is designed to achieve a lightweight fan blade having an optimal level of stiffness.

The present invention generally relates to multi-layer, flat glass structures and a method of manufacturing multi-layer, flat glass structures.

A laminating machine comprises at least one material source, configured as a sheet feeder, for sheets of a material to be laminated. The laminating machine further comprises at least one laminating unit. The laminating machine also comprises at least two lamination sources, each for at least one web-type laminating material. The laminating machine additionally comprises at least one laminating unit for producing a material web, which is laminated on both sides, from the sheets and the respective at least one laminating material. At least one lamination control device is disposed downstream of a laminating region of the laminating unit, along a transportation path provided for the transporting of the laminated material web. The control device monitors a control region, lying outside a transport region that is occupied by the transportation path provided for the laminated material web.

A roll tensioner for use in maintaining a wrapping material cut edge of a wrapping material retained on a wrapping material roll located within a wrapping material box having an interior cavity with an interior front wall with a top cutting edge. The roll tensioner comprises a thin, flexible main body having distal and proximal end sections separated by a spring back reversion section, and formed having a first side and a second side. Attachment means, preferably an adhesive, is located on at least a portion of the proximal end section on the first side adapted to attach the proximal end section to the interior front wall of the wrapping material box. The spring back reversion section is composed of a material that has an immediate elastic response to a static load and is capable of substantially full recovery when the static load is removed. The distal end mechanically bends downward by way of the spring back reversion section in the interior cavity of the wrapping material box. The distal end section is adapted to rest against the wrapping material proximal to the wrapping material cut edge to retain the wrapping material cut edge in an upward, substantially parallel position to the interior front wall of the wrapping material box for easy grasping of the wrapping material cut edge by an end user.

Laminated glazings with embedded wire circuits, have many uses. But, due to the higher cost of manufacture, they are not widely used. This invention provides a process to reduce the cost of production for embedded wire laminated glazing. Rather than embedding the wire one interlayer at a time, several circuits are produced on the same sheet, cut out and then inserted into the interlayer of each separate laminate during assembly, reducing the direct labor and capital investment required.

Provides a four-layer structure screen protective film and a manufacturing process thereof, comprising films arranged in sequence, from bottom up: bottom layer release film, single-sided silica gel segmented composite release film, single-sided silica gel hardened practical film, and top layer protective film; composite release film has break lines arranged along length direction, which segment composite release film into pieces; low-viscosity silica gel layer is fixedly arranged on lower surface, whose lower surface is bonded to upper surface of bottom layer release film; lower surface of single-sided silica gel hardened practical film has silica gel layer fixedly arranged, whose lower surface is bonded to composite release film. Being able to move on screen repeatedly during film-adjusting process, avoiding large area of silica gel exposing after whole face of release film is peeled off, thus avoiding from sucking dusts or cilia in air.

A decorative sheet according to one aspect of the present disclosure comprises a decorative plate and an adhesive layer disposed on a first side of the decorative plate. The decorative plate comprises (A) a decorative layer disposed on a second side from the first side, (B) a core layer made of a prepreg containing a fiber base material, and (C) a balancing layer including mixed paper containing an endothermic metal hydroxide as a base material.

A method of manufacturing an organic light emitting diode display is provided. The method includes: pasting a backboard to an underside of the flexible substrate by a viscosity-variable adhesive; severing the backboard located in the bended region from the backboard located in the non-bended region; peeling off the backboard located in the bended region; and performing a viscosity enhancement treatment to the viscosity-variable adhesive on the non-bended region.

A method for manufacturing a display unit according to an exemplary embodiment of one aspect of the present invention includes: unwinding a first film from a first film roll, and carrying the first film; attaching a second film onto the carried first film and forming an elongated film laminated body; forming a cutting line in the film laminated body in a width direction at intervals along a longitudinal direction and forming a film sheet piece; and laminating the film sheet piece on a first surface of a panel.

An absorbent core and an absorbent article respectively with improved properties, especially rewet performance, are disclosed. The absorbent core has at least two layers, wherein each layer comprising from 0 to 10% by weight fibrous material and from 90 to 100% by weight water-absorbent polymer particles, based on the sum of water-absorbent polymer particles and fibrous material. The surface-postcrosslinked water absorbent polymer particles within the upper layer have a sphericity of at least 0.89 and a CRC of at least 34 g/g. Preferably the water-absorbent polymer particles have a sphericity of at least 0.89 and the sum of the CRC and AUL (0.3 psi, 21 g cm.sup.2) (EDANA 442.2-02) of the water absorbent polymer particles is at least 65 g/g.
