    Abstract: In a method and a device for finishing an endless fabric, the endless fabric is transported past a rotating applicator roll that is wetted with a liquor, in order to apply the liquor onto the endless fabric. On the endless fabric that has been transported onwards, after drying, the thread add-on, or its change, is measured and evaluated on an ongoing basis by a sensor, in order to regulate the rotational speed of the application roll as a function of the measuring result. A device is suitable for implementing the method.

  • Publication number: 20080030876
    Abstract: A method is provided for manufacturing a high-precision mold whereby a feature matching a desired feature design is carved into a hard mold material (41) using, for example, a diamond grinding wheel and/or a diamond turning point. Inherent imprecision and errors (49) introduced by the use of the grinding wheel/turning point are measured to determine deviations from the desired feature design. An ultrafast shortpulse laser is then activated to desirably ablate the deviations, thereby correcting the errors and conforming the feature to the desired shape. Furthermore, a thin film (1602) may be formed over the feature either prior to or after the laser ablation process, where the error measurement and laser ablation processes detects and ablates errors on the surface of the thin film, respectively. Additionally, the laser ablation process may be applied directly to, for example, an optical lens (1400) formed from an imprecise mold to remove any errors and imperfections thereon.

  • Patent number: 7311938
    Abstract: A method is provided for coating optical lenses and other optical articles with anti-reflection (AR) coatings. The lenses have low reflectivity, provide a substantially white light reflection and have a low stress AR coating and are ideally suited for optical lenses made using a molding procedure which provides a low stress lens substrate. In one aspect the method uses special coating compositions with one being a high index of refraction composition and the other being a low index of refraction composition. In another aspect a method is also disclosed using an optical monitor in conjunction with a conventional vapor deposition apparatus whereby an optical reference lens is used and a particular light frequency of reflected light is measured and this measurement is then used to determine when the desired optical coating is achieved. In a still further aspect the method also preferably calculates the optical thickness of each layer using a specific ratio of blue to green to red colors in the reflected light.

    Abstract: A vapor deposition process for depositing TiO2 and a vapor desposition process for depositing SiO2 are alternately repeated in a multi-layer film forming process. A refractive index that a thin film formed by each vapor depositing will provide is individually determined prior to each relative vapor depositing, and vapor deposition control data is prepared based on such a refractive index. Each vapor deposition is controlled by using a relative vapor deposition control data thus prepared. Therefore, each vapor deposition process can be accurately controlled according to the refractive index of a thin film even if repeated vapor deposition processes change the refractive index. Accordingly, a multilayer film having desired optical characteristics can be formed.

  • Patent number: 6716283
    Abstract: In an annealing process in which laser light is irradiated to a semiconductor thin film, a refractive index of the semiconductor thin film after laser light irradiation is measured and conditions for the next laser light irradiation are adjusted based on the measured refractive index value. For example, laser light irradiation conditions are adjusted so that semiconductor thin films always have the same refractive index. As a result, the annealing can be performed under the same conditions at every laser light irradiation even if the laser light irradiation conditions vary unavoidably.

  • Patent number: 6713120
    Abstract: A coating unit for coating a substrate with a treatment solution and a peripheral aligner, which has a mounting table rotatable and movable in at least one direction and irradiates the peripheral portion of the substrate on the mounting table with light from an irradiating portion to expose a coating film on the substrate, are provided in a substrate processing system. The peripheral aligner has film thickness measuring means provided with a sensor member for measuring a film thickness of the coating film. It is not necessary to separately provide a unit for measuring the film thickness outside of the system, thus preventing the substrate from being contaminated or dropped to be damaged when the film thickness is measured.
