  • Publication number: 20200345229
    Abstract: Disclosed is a fundus camera, which relates to the technical field of medical devices and includes: an illumination module, a main optical assembly, a focusing module, and an image sensing acquisition module; the illumination module includes a plurality of light sources configured to emit light of different wavelengths, illumination light emitted by the plurality of light sources is conducted to enter an eye of a patient through the main optical assembly, and light reflected by a retina of the patient is conducted to pass through the main optical assembly and the focusing module to enter the image sensing acquisition module. The fundus camera provided by the present application improves the technical problem that the fundus camera in the prior art cannot image different layers of the retina, thereby providing valuable medical and diagnostic data.

  • Publication number: 20200329962
    Abstract: Retina digital imaging system, instrument and method A retina digital imaging system includes: an illumination module (1), a main optical assembly (3), and an image sensor module (2); the illumination module (1) includes light-emitting diodes capable of emitting light with different wavelengths, and each light-emitting diode emits light to enter the retina through the main optical assembly (3) to form an illumination optical path; the light reflected by the retina passes through the main optical assembly (3) and forms an image on the image sensor module (2) to form an imaging optical path. The various spectral bands formed by light-emitting diodes may form a wider spectrum, so different layers of the retina may be imaged to provide valuable medical and diagnostic data.

  • Patent number: 8883669
    Abstract: The present invention relates to a hydrocracking catalyst comprising an acidic silica-alumina, an optional alumina, an effective quantity of at least one VIII Group metal component(s), an effective quantity of at least one VIB Group metal component(s) and an organic additive, wherein the organic additive is one or more selected from the group consisting of an oxygen-containing or nitrogen-containing organic compound, and the molar ratio of the organic additive to the VIII Group metal component(s) is 0.01-10. The present invention relates further to a process for producing the hydrocracking catalyst and use of the catalyst in a process for hydrocracking hydrocarbon oils. The hydrocracking catalyst provided according to the present invention shows a higher activity for aromatic hydrosaturating and ring-opening reaction, as compared with the prior art hydrocracking catalyst.

  • Patent number: 8529754
    Abstract: The present invention relates to a catalytic conversion process for producing more diesel and propylene, comprising contacting the feedstock oil with a catalyst having a relatively homogeneous activity in a reactor, wherein the reaction temperature, weight hourly space velocity and weight ratio of the catalyst/feedstock oil are sufficient to obtain a reaction product containing from 12 to 60% by weight of a fluid catalytic cracking gas oil relative to the weight of the feedstock oil; the fluid catalytic cracking gas oil is fed into the fluid catalytic cracking gas oil treatment device for further processing. Catalytic cracking, hydrogenation, solvent extraction, hydrocracking and process for producing more diesel are organically combined together, and hydrocarbons such as alkanes, alkyl side chains in the feedstock for catalysis are selectively cracked and isomerized.
