  • Publication number: 20220290476
    Abstract: An actuating mechanism for actuating a charging or fueling flap on a charging or fueling compartment received on or in a body component of a vehicle, wherein the charging or fueling flap is reversibly movable between a closed position and an open position, wherein a flap lock is provided for locking the charging or fueling flap in its closed position. The actuating mechanism includes a drive having a drive shaft, which is operatively connectable to the charging or fueling flap such that, upon rotation of the drive shaft, the charging or fueling flap is movable relative to the charging or fueling compartment. The actuating mechanism further includes a mechanical control or switching mechanism, which is configured such that, upon rotation of the drive shaft to manipulate the flap lock, a rotational movement of the drive shaft can be tapped with the aid of the mechanical control or switching mechanism.

  • Patent number: 10807901
    Abstract: One aspect relates to a method for producing an optical blank from synthetic quartz glass by vitrifying and shaping a porous, cylindrical SiO2 soot body having a longitudinal axis, in a heating zone including a melt mold with bottom plate. The SiO2 soot body vitrified in the heating zone at a vitrification temperature so as to form a full cylindrical, completely vitrified, transparent quartz glass body. Subsequently, the vitrified quartz glass body is shaped by softening in the melt mold at a softening temperature so as to form a viscous quartz glass mass which partly fills the volume of the melt mold, and cooling the quartz glass mass and removal from the melt mold so as to form the optical blank. During shaping in the melt mold, the full cylindrical quartz glass body is brought into contact by way of controlled supply with a centering means of the bottom plate.

  • Publication number: 20170217814
    Abstract: A method for producing a blank from titanium-doped, highly silicic-acidic glass having a specified fluorine content for use in EUV lithography is described, in which the thermal expansion coefficient over the operating temperature remains at zero as stably as possible. The course of the thermal expansion coefficient of Ti-doped silica glass depends on a plurality of influencing factors. In addition to the absolute titanium content, the distribution of the titanium is of significant importance, as is the ratio and distribution of additional doping elements, such as fluorine. In the method, fluorine-doped TiO2—SiO2 soot particles are generated and processed further via consolidation and vitrifying into the blank, and, by flame hydrolysis of input substances containing silicon and titanium, TiO2—SiO2-soot particles are formed, exposed to a reagent containing fluorine in a moving powder bed, and converted to the fluorine-doped TiO2—SiO2-soot particles.

  • Patent number: 9593034
    Abstract: A method for producing a blank of iron-doped silica glass with high silicic acid content for use as heat protection glass is provided. The method involves: (a) producing an iron-doped SiO2 soot body which contains iron in a first oxidation state Fe3+ by flame hydrolysis of a silicon-containing and an iron-containing starting substance, (b) drying the soot body to obtain a mean hydroxyl group content of less than 10 ppm by weight, and (c) vitrifying the soot body under a reducing atmosphere that is suitable for at least partially reducing the iron from the first oxidation state Fe3+ to a second, lower oxidation state Fe2+. A blank is obtained having an iron content between 0.1 and 1% by weight which exhibits an internal transmission of at most 40% in the infrared wavelength range and an internal transmission of at least 85% in the visible spectral range.

  • Patent number: 9586850
    Abstract: The Ti3+ ions present in Ti-doped silica glass cause a brown staining of the glass, causing inspection of the lens to become more difficult. Known methods for reducing Ti3+ ions in favor of Ti4+ ions in Ti-doped silica glass include a sufficiently high proportion of OH-groups and carrying out an oxygen treatment prior to vitrification, which both have disadvantages. In order to provide a cost-efficient production method for Ti-doped silica glass, which at a hydroxyl group content of less than 120 ppm shows an internal transmittance (sample thickness 10 mm) of at least 70% in the wavelength range of 400 nm to 1000 nm, the TiO2—SiO2 soot body is subjected to a conditioning treatment with a nitrogen oxide prior to vitrification. The blank produced in this way from Ti-doped silica glass has the ratio Ti3+/Ti4+?5×10?4.

    Abstract: A method for producing a silica glass blank co-doped with titanium and fluorine for use in EUV lithography includes (a) producing a TiO2—SiO2 soot body by flame hydrolysis of silicon- and titanium-containing precursor substances, (b) fluorinating the TiO2—SiO2 soot body to form a fluorine-doped TiO2—SiO2 soot body, (c) treating the fluorine-doped TiO2—SiO2 soot body in a water vapor-containing atmosphere to form a conditioned soot body, and (d) vitrifying the conditioned soot body to form the blank. The blank has an internal transmission of at least 60% in the wavelength range of 400 to 700 nm at a sample thickness of 10 mm, a mean OH content in the range of 10 to 100 wt. ppm and a mean fluorine content in the range of 2,500 to 10,000 wt. ppm.

  • Patent number: 9540271
    Abstract: A blank made of titanium-doped silica glass for a mirror substrate for use in EUV lithography is provided. The blank includes a surface portion to be provided with a reflective film and having an optically used area (CA) over which a coefficient of thermal expansion (CTE) has a two-dimensional inhomogeneity (dCTE) distribution profile averaged over a thickness of the blank. A maximum inhomogeneity (dCTEmax) of less than 5 ppb/K is defined as a difference between a CTE maximum value and a CTE minimum value. The dCTEmax is at least 0.5 ppb/K. The CA forms a non-circular area having a centroid. The dCTE distribution profile is not rotation-symmetrical and is defined over the CA, such that straight profile sections normalized to a unit length and extending through the centroid of the area yield a dCTE family of curves forming a curve band with a bandwidth of less than 0.5×dCTEmax.
