In a method for embodying a hotplate for a hob, at least one metallic layer and a further layer under the metallic layer are formed on an underside of the hotplate. After applying the at least one metallic layer and the further layer, at least one region of the metallic layer is changed by a laser light of a laser beam so that the further layer is recognized when viewing the hob on a topside.

The invention concerns reflective opaque panels that can be used as facing panels or decorative panels. They consist of a substrate coated with a stack of layers comprising, in the following order, at least (i) a transparent substrate (S), (ii) a first dielectric layer which is a high refractive index dielectric layer (H1), (iii) a second dielectric layer which is a low refractive index dielectric layer (L1), and (vi) a single chromium-based layer.

An electronic device may include electrical components and other components mounted within a housing. The device may have a display on a front face of the device and may have a glass layer that forms part of the housing on a rear face of the device. The glass layer and other glass structures in the electronic device may be provided with coatings. An interior coating on a glass layer may include multiple layers of material such as an adhesion promotion layer, thin-film layers of materials such as silicon, niobium oxide and other metal oxides, and metals to help adjust the appearance of the coating. A metal layer may be formed on top of the coating to serve as an environmental protection layer and opacity enhancement layer. In some configurations, the coating may include four layers.

A method of manufacturing a glass container in preparation for direct digital printing includes forming a glass container having a glass wall and applying a primer coating to the glass container. The primer coating is applied by directing an atomized spray of an aqueous primer composition onto the glass container over an adherent base layer, such as a hot-end coating, which deposits the primer coating, followed by heating the primer coating with a heat source such as a flame. Upon being heated, the clarity of the primer coating is increased. As a result, a decorative marking may be printed onto the glass container without having to pretreat the glass container in a way that involves pyrolytically depositing a layer of silicon dioxide onto the glass container prior to printing.

A black-colored article which is not a photovoltaic device. The device includes a substantially transparent substrate; a substantially transparent textured layer provided upon a first surface of the substrate, the textured layer having a textured surface oriented away from the substrate; and an absorption layer including a silicon-germanium alloy, the absorption layer being situated upon the textured surface of the textured layer.

Techniques, processes and structures are disclosed for providing markings on products, such as electronic devices. For example, the markings can be formed using physical vapor deposition (PVD) processes to deposit a layer of material. The markings or labels may be textual and/or graphic. The markings are deposited on a compliant layer that is disposed on a surface to be marked. The compliant layer is arranged to isolate the surface to be marked from the layer of material deposited using the PVD process.

An opaque cover for a capacitive sensor is provided. The cover includes a transparent substrate and a black color stack disposed adjacent the transparent substrate. The black color stack includes a pigment stack having a first dielectric layer, a second dielectric layer, and a first light absorbing layer positioned between the first and second dielectric layers. The first dielectric layer has a first refractive index. The second dielectric layer has a second refractive index different from the first refractive index. The black color stack also includes a plurality of second light absorption layers interleaved with a plurality of third dielectric layer.

A heating cooker includes: a top plate on which a cooking container to be heated is placed; an outer case as a main body having an upper surface on which the top plate is placed; a heater heating the cooking container; and a light emitting device disposed in the outer case, for displaying the heating state. The top plate includes: a glass substrate having a transparent light-transmitting low-expansion crystallized glass made mainly of Li.sub.2OAL.sub.2O.sub.3SiO.sub.2 and having -quartz solid solution, having a crystal size smaller than the wavelength of visible light; a design layer having a black-based color disposed on an undersurface of the glass substrate; a diffusion region disposed partially on an undersurface of the design layer, for diffusedly emitting light from the light emitting device; and a light-blocking layer disposed on the undersurface of the design layer other than the diffusion region, for blocking light from below.

The invention relates to an almost opaque decorative glass panel comprising a substrate made of a vitreous material bearing a multilayer stack including at least one light-absorbing functional layer and transparent dielectric coatings such that the light-absorbing functional layer is enclosed between dielectric coatings. The light-absorbing functional layer has a geometric thickness comprised between 25 and 140 nm, and an extinction coefficient k of at least 1.8. The multilayer stack in addition comprises at least one attenuating layer placed between the substrate and the light-absorbing functional layer, having a thickness comprised between 1 and 50 nm, having a refractive index n higher than 1 and an extinction coefficient k of at least 0.5. Furthermore, a transparent dielectric coating the optical thickness of which is comprised between 30 and 160 nm, and the refractive index n of which is higher than 1.5, is placed adjacent to the attenuating layer on the side opposite the light-absorbing functional layer. The invention provides a decorative panel offering a pleasant aesthetic effect.

The invention relates to a method for partially coating a surface of an object, comprising the following steps: (a) optional hydrophobization of the surface of the object; (b) partial application of (b1) a liquid and subsequent application of a powderous or granular substance or (b2) a solution or suspension of said powderous or granular substance in a liquid; (c) drying the surface to form spatially-delimited salt or powder crusts; (d) coating the surface with at least one layer of a metal or a metal compound; and (e) removing the salt or powder crusts that have been produced. The invention also relates to products that have been produced according to the claimed method.
