A glass screen protector manufacturing method of a progressive non-through hole glass screen protector includes the steps of cutting a glass screen protector pattern; CNC machining the glass screen protector for a side edge, a progressive sensing area, and a desired hole position thereof; polishing the glass screen protector; reinforcing the glass screen protector; coating the glass screen protector with a nano coating; and gluing a backing to the glass screen protector.

Techniques for modifying surfaces of electrodes are provided. An electrode surface can be processed by applying an abrasive material or chemical solution to or against the surface to modify the surface to reduce the amount of roughness on, and/or alter the shape of, the surface. The shape of the surface can be altered by rounding or doming the surface. During surface processing, flexible or compressible support material can be applied to the back of an abrasive material, such as sandpaper, to desirably distribute pressure from the support material to the sandpaper and/or mold the shape of the sandpaper to facilitate maintaining desirable contact by the sandpaper on electrode surfaces. With regard to a flexible circuit board on which electrodes are formed, a vacuum chuck component or a temporary abrasive can be used to hold the circuit board in a flat and stationary position during surface processing.

A waveguide includes an input area, a multi-layered substrate, and an output area. The multi-layered substrate includes a plurality of layers of at least a substrate and at least one partially reflective layers. The input area in-couples light in a first band into the waveguide. The one or more partially reflective layers are partially reflective to light in the first band. Each of the one or more partially reflective layers are located between respective layers of the plurality of layers of the substrate. The output area out-couples light from the waveguide. The pupil replication density of the out-coupled light is based in part on a number of the one or more partially reflective layers and respective locations of the one or more partially reflective layers in the waveguide.

A lapping apparatus includes a processing part and a fixing part. The processing part is provided for a target object to be seated and polishes a lower surface of the target object seated as it rotates. The fixing part is provided for pressing the seated target object against the processing part so that the lower surface of the target object is fixed in a state of being seated on the processing part. The fixing part rotates relative to the processing part along with the target object by shear force applied to the target object from the processing part so that the processing of the lower surface of the target object is made when the processing part rotates while the fixing part fixes the target object, and the location axes of the fixing part and the processing part do not match.

A method for manufacturing a breathable hybrid leather includes: a raw material supply step of supplying the natural leather of recycled leather; a step of applying a hot-melt adhesive to the upper surface of the leather raw material; a bonding step of supplying a fabric to the upper surface of the adhesive layer and applying heat and pressure to the leather raw material, the adhesive layer, and the fabric to obtain a bonded fabric; and a step of ironing and coating the bonded fabric a plurality of times.

Described herein are a bonded ceramic having a channel through which a fluid can flow, and a method for manufacturing the same. The bonded ceramic includes: a first ceramic base material; and a second ceramic base material, wherein: the first ceramic base material and the second ceramic base material are bonded by adhesive layer-free bonding; a pattern is formed on either or both of the bonding surface of the first ceramic base material where the first ceramic base material comes in contact with the second ceramic base material and the bonding surface of the second ceramic base material where the second ceramic base material comes in contact with the first ceramic base material; and the bonded ceramic includes pores having a size of 0.01 m to 50 m and formed along the bonding surface between the first ceramic base material and the second ceramic base material.

There is provided a laminated hybrid metallized polymer film for erosion protection of a composite structure. The laminated hybrid metallized polymer film includes a metal foil layer, a laminating adhesive layer underlying the metal foil layer, and a polymer film layer underlying the laminating adhesive layer. The polymer film layer is laminated to the metal foil layer with the laminating adhesive layer coupled between the metal foil layer and the polymer film layer. The laminated hybrid metallized polymer film further includes an adhesive layer underlying the polymer film layer. The adhesive layer adheres the polymer film layer to a substrate surface of the composite structure. The metal foil layer, the laminating adhesive layer, the polymer film layer, and the adhesive layer form the laminated hybrid metallized polymer film for application over and to the substrate surface of the composite structure.

A leveling apparatus used in a cutting process after forming process of a pouch-type secondary battery, and the leveling apparatus includes: a roller assembly having pairs of upper rollers and lower rollers arranged in at least two rows for rolling in contact with upper and lower surfaces adjacent to both rim edges of the pouch-type secondary battery; and a support frame supporting the roller assembly, wherein the roller assembly applies rolling with respect to the upper and lower surfaces adjacent to both rim edges of the pouch-type secondary battery to thereby remove stress.

A resin composite having excellent strength is easily produced by using a resin foam having a specific surface roughness (Ra) as the core material of the resin composite.
