  • Patent number: 8822369
    Abstract: The present invention relates to a method for producing a hydrocarbon-producing catalyst for producing a hydrocarbon from a mixed gas of carbon monoxide and hydrogen and provides a method for producing, with stability and at high productivity, a hydrocarbon-producing catalyst with which the rate of conversion of carbon monoxide to hydrocarbon is high, the methane selectivity is low, the high activity can be maintained over a long period, the desorption of the active metal is unlikely to occur, and the durability is excellent. The method includes a precursor film forming step of putting a sol solution of an active metal compound and a metal oxide precursor in contact with a heated catalyst carrier 2 to form a precursor film on a surface of the catalyst carrier 2, and a hydrolysis step of gelling the precursor film by hydrolysis to form a metal oxide gel film 4, with the active metal 6 dispersed uniformly, on the surface of the catalyst carrier 2.

  • Patent number: 8520483
    Abstract: A method for processing information is provided. The method includes directing a laser beam to a first track of a first layer of a holographic storage medium. The method also includes recording a base voltage based on a look-up table. The method includes directing the laser beam to a target track in the first layer, based on position information in tracks. Further, the method includes recording an offset voltage for the target track into the look-up table. Still further, the method includes directing the laser beam to a target layer based on position information in vertical wobbles. The method also includes recording an offset voltage for the target layer into the look-up table. Finally, the method includes determining a final voltage based on the look-up table and applying the final voltage to an actuator for moving the laser beam to a final target position in the holographic storage medium for recording and retrieval of information.

  • Patent number: 8384573
    Abstract: A digital-to-analog converter (DAC) with a digital segment having a digital data input and an analog segment coupled to the digital segment and having an analog output to output an analog signal corresponding to the digital data. The analog segment includes one or more gain stages and a feedback structure to couple the analog output to the one or more gain stages to attenuate signal distortion at the analog output. A combined gain of the one or more gain stages determines a signal distortion attenuation characteristic of the analog segment.

  • Patent number: 8385178
    Abstract: Techniques are provided for using a multi-stage actuator to actuate one or more optical components of an optical head. The multi-stage actuator includes a cross-layer displacement component which actuates an optical component to change the beam focus in a displacement range corresponding to the thickness of the data layers in a holographic disk, such that a beam is impinged on the target data layer. The multi-stage actuator also includes a intra-layer focusing component which actuates the optical component in a smaller range to focus the beam on the target data position. The cross-layer displacement component and the intra-layer focusing component may each include more than one actuator. In some embodiments, the focusing component also actuates the optical component in a tilting motion to compensate for movement or imperfections of the disk during a reading or recording process.

  • Patent number: 8350104
    Abstract: To provide a method for catalytically cracking waste plastics wherein the efficiency in decomposition is high; even polyethylene composed of linear chain molecules difficult in decomposition is decomposable at a low temperature and decomposed residue is hardly produced; the process is simple since dechlorination can be achieved at the same time with catalytically cracking waste plastics in one reaction vessel; and oil fractions can be recovered at 50% or more on a net yield basis. The method for catalytically cracking waste plastics of the present invention has a constitution in which waste plastics are loaded as a raw material into a granular FCC catalyst heated to a temperature range from 350° C. to 500° C. inside a reaction vessel, thereby decomposing and gasifying the waste plastics in contact with the FCC catalyst.
