A head mold for a wig may include a head mold body and an information pattern. The head mold body may be formed using a stack type three-dimensional (3D) printer into which head information of a user may be inputted. The information pattern may be provided to the head mold body to indicate information of the wig. The head mold may be manufactured using the stack type 3D printer to prevent a generation of dusts during manufacturing the head mold. Further, the stack type 3D printer may have a low price compared to a milling machine to reduce an initial investment cost for manufacturing the head mold.

An imprint apparatus that transfers a pattern of a mold to an imprint material on a substrate, includes: a mold having a pattern region in which the pattern is formed; a substrate holding unit having a substrate mounting surface on which the substrate is mounted; a driving unit configured to drive the mold and press the mold against the substrate coated with an imprint material at three or more positions; and a control unit configured to control a pressing force of the driving unit based on a distance in an XY plane parallel to the substrate mounting surface between the driving unit and a top portion of a convex shape of at least one of the mold and the substrate deformed by the deformation mechanism.

Provided are an imprint mold having a plurality of recesses constituting a predetermined mold pattern, in which the imprint mold comprises a stack, comprising a plurality of mold base material layers and an etching stopper layer interposed between the mold base material layers, on a substrate, the stack has the plurality of recesses having different depths, the mold base material layer and the etching stopper layer are made of materials having etching selectivity for each other, and each of the plurality of recesses has a bottom surface on which the etching stopper layer is exposed, and technology related thereto.

Provided is a display apparatus for a three-dimensional (3D) head-up display (HUD), the display apparatus including a transparent substrate, a polarizing film layer provided on the transparent substrate, and a lenticular lens provided on the polarizing film layer opposite to the transparent substrate, wherein the lenticular lens includes an adhesive layer, a base substrate provided on the adhesive layer, and a pattern layer provided on the base substrate opposite to the adhesive layer.

A reusable vehicular jack pad system, including a plurality of jack pads, each respective pad further including a top face, an oppositely disposed bottom face, a jack-engaging assembly operationally connected to the top face, a palm portion, and a toe portion extending from the palm portion. Each respective jack pad is shaped like an animal paw. Each respective bottom face is contoured to leave a paw print in soft ground. Each respective top face is contoured to stackingly engage a respective bottom face.
