ActiveUS20090277224A1Reduce supporting costsMaximizes stiffnessSolar heating energySolar heat devicesProduction rateProduction line
A method of manufacturing monolithic glass reflectors for concentrating sunlight in a solar energy system is disclosed. The method of manufacturing allows large monolithic glass reflectors to be made from float glass in order to realize significant cost savings on the total system cost for a solar energy system. The method of manufacture includes steps of heating a sheet of float glass positioned over a concave mold until the sheet of glass sags and stretches to conform to the shape of the mold. The edges of the dish-shaped glass are rolled for structural stiffening around the periphery. The dish-shaped glass is then silvered to create a dish-shaped mirror that reflects solar radiation to a focus. The surface of the mold that contacts the float glass preferably has a grooved surface profile comprising a plurality of cusps and concave valleys. This grooved profile minimizes the contact area and marring of the specular glass surface, reduces parasitic heat transfer into the mold and increases mold lifetime. The disclosed method of manufacture is capable of high production rates sufficiently fast to accommodate the output of a conventional float glass production line so that monolithic glass reflectors can be produced as quickly as a float glass production can make sheets of float glass to be used in the process.

Manufacturing method and manufacturing apparatus of envelope
In a manufacturing method of forming a hermetically sealed container by bringing a pair of substrates into intimate contact via a supporting frame between them, one of the substrates is warped in a depressurized atmosphere before getting into intimate contact and is thereby separated from the other substrate so as to evacuate inside of the hermetically sealed container by releasing the depressurized atmosphere therein. Relative positions of the substrates are restored by having the warp undone thereafter. Therefore, it is possible to achieve evacuation inside the hermetically sealed container without causing the relative positions of the substrates to deviate.

Systems and methods are described for forming continuous curved laser filaments in transparent materials. The filaments are preferably curved and C-shaped. Filaments may employ other curved profiles (shapes). A burst of ultrafast laser pulses is focused such that a beam waist is formed external to the material being processed without forming an external plasma channel, while a sufficient energy density is formed within an extended region within the material to support the formation of a continuous filament, without causing optical breakdown within the material. Filaments formed according to this method may exhibit lengths in the range of 100 μm-10 mm. An aberrated optical focusing element is employed to produce an external beam waist while producing distributed focusing of the incident beam within the material. Optical monitoring of the filaments may be employed to provide feedback to facilitate active control of the process.
