  • Patent number: 9594021
    Abstract: An apparatus is provided for detecting transmittance of a trench. The trench is located on an infrared-transmittable material, which can be a wafer. The wafer is obtained after a ditching process. An image of the wafer is fetched. The contrast of the image is greatly enhanced.

  • Publication number: 20160304368
    Abstract: An active photocatalytic reactor configured to process biological culturing water with an accelerated process. Water to be used in a biological culturing system is stabilized with pollutants in the water reduced. The active photocatalytic reactor is less affected by outside environment while having faster activating speed. The active photocatalytic reactor can further be combined with a traditional filter to form a serial or parallel connection for more effectively purifying the culturing water with damage to the whole system avoided.

  • Patent number: 9145601
    Abstract: A composite material which expands the range of light-absorption of an original constitution material, which is formed through two or more total oxides contacting and fixing to the oxygen reduced oxides with the same composition of materials as the total oxides. The composite material can excite the light-driven reaction to achieve an enlarged absorption range of the light band. In the contacting and fixing process of the composite material, a calcination process is not required, so that the process can be applied to a substrate which is plastic or not suitable for high-temperature heating.

  • Patent number: 8767196
    Abstract: A method for measuring propagation loss in a plane light guide plate, which includes the following steps of making an input light generated by an input light generator pass through an optical coupler, an optical reflection device individually or pass through the optical coupler first and then the optical reflection device, and finally propagate toward an optical measurement device to obtain at least one optical parameter according to the optical coupler, the optical reflection device or the combination thereof; and making the input light pass through the optical coupler and then the plane light guide plate, and further pass through the plane light guide plate from one side thereof toward the optical reflection device in order to reflect the input light toward the optical measurement device, so as to obtain a propagation loss of the plane light guide plate according to the at least one optical parameter.

  • Publication number: 20120141691
    Abstract: The method of the present invention comprises the following three steps: (1) Coating titanium oxide in the form of a membrane, nanometer-sized particles or powder onto a substrate to form a preliminary coating; (2) Adding a reducing agent and a dispersing agent to a metallic precursor to form a solution and then using an application device to apply a small amount of the solution to the preliminary coating; and (3) Using ultraviolet radiation on the substrate to reduce the metallic precursor to a metal via photochemical reaction and hence to form a composite coating. The method is simple and may be used for substrates in different sizes. In addition, in the method, the solution may be evenly spread out on the preliminary coating. The final composite coating may be used as the electrodes of a proton exchange membrane fuel cell.

  • Patent number: 7927553
    Abstract: A photocatalytic reactor is disclosed herein, which includes a rotatable light guide plate and a light source. The light guide plate is coated with a photocatalyst film on a surface thereof. A light beam emitted from the light source can be coupled into and propagate inside the light guide plate to activate the photocatalysis of the photocatalyst film. Additionally, the rotation of the light guide plate further expedites the photocatalysis so as to enhance the reaction efficiency of the photocatalytic reactor.

  • Publication number: 20080308405
    Abstract: An optical fiber photocatalytic reactor is provided. The reactor comprises a reaction zone and multiple fibers located in the reaction zone. The fiber comprises a photocatalyst that is coated onto its surface via a thermal hydrolysis method. The adhesion between the fiber and the photocatalyst thereon is strong, and thus, the delamination of the photocatalyst film on the fiber can be prevented. Moreover, the optical fiber photocatalytic reactor is useful for the decomposition of nitrogen oxide which is one of air's most harmful contaminants. The present invention exhibits a high conversion of nitrogen oxide.
