A method forming an elastic undulated layer locally lying on a substrate from a structure including a strained elastic layer on a foundation in a solid state present at a surface of a rigid substrate, the method including: melting a foundation for a duration of at least 50 ns, the foundation thickness being at least 20 nm and lower than a predetermined thickness corresponding to a theoretical peak-to-peak amplitude of wrinkles, the melting generating a simultaneous deformation, by forming wrinkles, of the elastic layer and the foundation and accompanied by localized adherent contact between the elastic layer and the rigid substrate in zones separating regions of the foundation; solidifying the foundation to bring it back to the solid state; removing the foundation brought back to the solid state to suspend a layer above the substrate outside the zones of localized adherent contact, the suspended layer being undulated in accordance with the wrinkles.

Provided are a glass body for pressure forming enabling press forming in a low-temperature range without the need of a special mold material, and a method for manufacturing the same. A glass body for pressure forming 1 having a porosified layer 1b formed by porosifying a surface thereof and having a Vickers hardness of 85 N/mm2 or less on the porosified surface. The porosified layer 1b can be manufactured by phase-separating the glass body by spinodal decomposition, acid-treating the phase-separated glass body and then treating the acid-treated glass body with alkali or hot water to porosify the surface of the glass body.

摘要:
The invention is a method for structuring a flat substrate composed of glass material in the course of a viscous flow process. The glass flat substrate is joined to a surface of a flat substrate, which is preferably a semiconductor flat substrate, having at least one depression bounded by a circumferential edge located in the surface. In the course of a subsequent tempering process, glass material is changed to a viscous free-flowing state in which at least proportions of the free-flowing glass material of the flat substrate flow over the circumferential edge into the depression in the flat substrate. The invention is also characterized in that a flat substrate is provided of which the at least one depression has at least one wetting surface that is countersunk with respect to the surface of the flat substrate and is at least partly bounded by a line-type edge which, at the same time, is an edge of a trench structure provided within the depression and countersunk with respect to the wetting surface and/or is determined by a discontinuous change in a wetting property for the free-flowing glass material that can be assigned to the wetting surface.
摘要:
An apparatus and method for heat treating a plurality of glass substrates. The glass substrates are supported on support platform and housed in a heat treating furnace. The substrates are supported in a substantially vertical orientation by restraining pins extending through walls of the furnace, and are separated from each other by frame-shaped spacing members. The spacing members reduce convection currents between the substrates and reduce or eliminate the post-heat treating distortion of each glass substrate to less than 100 μm over the entire surface of the substrate.
摘要:
A glass sheet is placed on a mold and heated to a first temperature. The glass sheet is then formed into a glass article having a three-dimensional shape using the mold. An isothermal heat transfer device comprising at least one heat pipe is provided in thermal contact with the mold. With the glass article on the mold and the isothermal heat transfer device in thermal contact with the mold, the glass article, mold, and isothermal heat transfer device are transported along a thermally-graded channel to cool the glass article to a second temperature. During the transporting, the isothermal heat transfer device transfers heat from a relatively hot region of the mold to a relatively cold region of the mold.

The present invention relates to a method for manufacturing a non-planar product in glass-ceramic. Said method comprises the following steps: (i) in a conventional furnace (3), heating a sheet of precursor glass of said glass-ceramic, so that said sheet becomes formable while avoiding its ceramming; (ii) forming said heated sheet; (iii) cooling said formed sheet (2b); (iv) ceramming said formed, cooled sheet.

The present invention discloses an integrated glass including opposite outer and inner surfaces and a solid sculpted area formed either on the outer surface or the inner surface. The solid sculpted area includes a number of concave shapes or convex shapes which can be used to form letters, numbers or patterns for user decorating or identifying. Besides, a mold for fabricating the integrated glass, a method for making the integrated glass, and a touch sensor device with such integrated glass are also disclosed by the present invention.
摘要:
An apparatus for manufacturing a single-curved glass sheet with little difference between the radius of curvature of a front end portion and the radius of curvature of a rear end portion of the glass sheet. The apparatus includes a heating furnace and a cooling device. The cooling device is provided with a plurality of upper nozzles for spraying cooling air onto an upper surface of heated/molded curved glass sheet. The upper nozzles are moved by movement means parallel to a path of travel of the glass sheet.
摘要:
A method and machine for obtaining bent glass sheets. Glass sheets are brought to their softening temperature, then they are caused to travel over a shaping bed of advancing elements for advancing them which are arranged along a path having a circular arc-shaped profile, the sheets progressively assuming their shape on entering the bed and over a first shaping zone, then being hardened by tempering or cooling in a second zone of the bed until they leave, and then the bent glass sheets thus obtained are recovered. The shaping bed is produced with a profile extending in a circular arc of more than 90°, and, on leaving the shaping bed, the hardened glass sheets are moved in a direction opposite that in which they were fed in.
