A decoration panel for home appliances having excellent reflectivity and durability, the decoration panel being applicable to outer sides of various home appliances, a home appliance including the decoration panel, and a method for manufacturing the decoration panel. More specifically, the decoration panel for home appliances includes: an aluminum substrate with one surface in which an engraved pattern having a preset width and a preset depth is formed, the engraved pattern having micro unevenness formed in a surface of the engraved pattern; a porous aluminum oxide layer formed on the engraved pattern; and a sealing layer formed to close a plurality of pores of the porous aluminum oxide layer, wherein an edge of the aluminum substrate is in a Chamfering (C) shape or a Rounding (R) shape.

A method of producing customized artwork includes forming and finishing a plurality of backdrops by cutting and/or engraving sheet metal. Based upon an order received for a customized artwork a particular backdrop is selected and a customized ornamental component is produced in sheet metal. If the backdrop and customized component are prone to galvanic corrosion, insulation may be provided between the customized component and backdrop and to insulate fasteners from either the customized component or backdrop. The method reduces lead times and production costs for customized artwork, while improving quality of the final product.

Systems, methods, and devices for producing appliances for expansion of the arch of a patient are provided. An arch expanding appliance comprises a force generating portion to apply an arch expansion force and a retention portion to hold the force generating portion on the teeth. The retention portion comprises a flexible portion and a stiff portion. The force generating portion applies a force to move teeth associated with the flexible portion, while the stiff portion resists movement of its associated teeth. The orthodontic appliances can be designed according to the specifications provided herein and manufactured using direct fabrication methods.

In some embodiments, a method may include selectively applying a mask to a first surface of a substrate. The mask may include one or more components defining a selected pattern and having a non-uniform density. The method may further include etching the first surface of the substrate based on the mask and selectively processing the first surface of the substrate to produce a multi-dimensional artwork.

An element chip manufacturing method includes a preparation process of preparing a substrate which includes a first surface having an exposed bump and a second surface opposite to the first surface and includes a plurality of element regions defined by dividing regions, a bump embedding process of embedding at least a head top part of the bump into the adhesive layer, a mask forming process of forming a mask in the second surface. The method for manufacturing the element chip includes a holding process of arranging the first surface to oppose a holding tape supported on a frame and holding the substrate on the holding tape, a placement process of placing the substrate on a stage provided inside of a plasma processing apparatus through the holding tape, after the mask forming process and the holding process.

A Press element and a method for manufacturing a structured press element, wherein a heterogeneous mask is applied on a metallic base element, after which a surface treatment is carried out and the heterogeneous mask has a certain resistance to the surface treatment.

An exemplary embodiment discloses a process for cleaning semiconductor fabrication equipment parts with non-metallic surfaces. The process optionally includes providing a semiconductor fabrication part with a non-metallic surface to be cleaned and applying a dilute aqueous solution to remove contamination from the non-metallic surface. The aqueous solution optionally includes dilute amounts of hydrofluoric acid, nitric acid and hydrogen peroxide. The dilute amounts would optionally be in the ranges of 0.5-1.5% wt. hydrofluoric acid, 0.1-0.5% wt. nitric acid and 1-10% wt. hydrogen peroxide.

The present invention relates to a metal such as titanium and niobium with differentially oxidized and/or nitridized layers for a metallic picture print, and method for producing the same. More specifically, this invention relates to a metal surface modified by differential oxidation and/or nitridation for making durable metallic picture prints to limit degradation to a picture print caused by UV radiation and chemical reactions.

Provided are an electronic device housing, a preparation method therefor and an electronic device therewith. The electronic device housing comprises a housing body and a logo layer, wherein the housing body is provided with a first surface and a second surface which are opposite each other, the first surface is provided with a first area and a second area which are adjacent to each other, the second area is located on the periphery of the first area, and the surface roughness of the second area is greater than that of the first area; and the logo layer is arranged on the first surface, and an orthographic projection of the logo layer on the first surface coincides with the first area.

Systems, methods, and devices for producing appliances for expansion of the palate of a patient are provided. A palate expanding orthodontic appliance comprises a teeth engagement portion comprising a plurality of teeth engagement structures and a force generating portion coupled to the teeth engagement portion and configured to apply force to cause the patient's palate to expand. The orthodontic appliances can be designed according to the specifications provided herein and manufactured using direct fabrication methods.
