    摘要： Surface-modified zeolites and methods for preparing surface-modified zeolites are provided. A hybrid polymer formed from a silicon alkoxide and a metal alkoxide, a co-monomer, or both, is contacted with a zeolite suspension. The zeolite suspension comprises a sodium-, an ammonium-, or a hydrogen-form zeolite and a solvent. The hybrid polymer and zeolite suspension are contacted under conditions sufficient to deposit hybrid polymer on external surfaces of the zeolite to form a treated zeolite. Solvent is removed therefrom. The treated zeolite is dried and calcinated to form a dried and calcinated treated zeolite. Forming of the zeolite suspension and the contacting, removing, drying, and calcinating steps are provided in one selectivation sequence to produce a surface-modified zeolite from the ammonium-form zeolite and the hydrogen-form zeolite. If the dried and calcinated treated zeolite is a sodium-form zeolite, the sodium is exchanged with ammonium and then additionally dried and calcinated.

    摘要： In a control circuit for a light-emitting device, a reference voltage generation circuit detects a full-wave rectified voltage and generates a first voltage as well as generating a second voltage by converting the rectified voltage into a DC voltage. A voltage corresponding to a difference between the first voltage and the second voltage or a voltage corresponding to a ratio of the first voltage to the second voltage is generated as a reference voltage by a subtraction circuit or by a division circuit, respectively. As a result, a change in amplitude of the reference voltage can be suppressed when amplitude of the rectified voltage is varied due to a variation in an AC input voltage supplied from an AC power supply.

    摘要： A method for processing an image divided into blocks of pixels is disclosed. The method comprises the steps of: detecting, for each block, a largest sub-block whose pixels have an equal luminance value; identifying, for each block, if the detected largest sub-block is or is not a natural texture; determining, for each block, a block blockiness level on the basis of the number of pixels within the detected largest sub-block and on the basis of the identification step; and processing the image on the basis of the block blockiness levels.
