  • Patent number: 7527419
    Abstract: A backlight assembly includes a lamp, a light guide plate, a receiving container and a lamp holder. The lamp generates light. The light guide plate has a light incident face through which the light generated by the lamp enters the light guide plate. The light guide plate guides the light. The receiving container has a base plate and sidewalls protruding from the edge portions of the base plate to define a receiving space for receiving the lamp and the light guide plate. The lamp holder holds an end portion of the lamp and includes a buffer portion. When an impact is applied to the backlight assembly, the buffer portion absorbs the impact to prevent damages to the lamp and the light guide plate.

  • Publication number: 20090098261
    Abstract: The present invention relates to a preparation method of protein extracts from rice bran which is comprising a process of pre-treating rice bran; producing de-fatted rice bran by removing fat from the pellet; a process of extracting protein from the de-fatted rice bran, generating protein solution; and a process of precipitating protein from the protein solution to obtain final protein extracts from rice bran. The method of the present invention makes it possible to obtain lipid from rice bran, which has been wasted and used only as feed or compost due to fast rancidity and low stability, and to ultimately develop proteineous materials of high quality, non-GMO and no-allergy by extracting protein from the rice bran. In addition, the present invention provides a method of recycling rice bran, which is wasted as a by-product, by adding values to the rice bran.

  • Publication number: 20090039948
    Abstract: A charge pump circuit includes first and second charge pumps and a detector. The first charge pump outputs a first charge pump signal of an intermediate voltage level by performing a charge pumping operation in response to a command signal. The detector outputs a detection signal in response to the command signal when a voltage level of an output node is lower than a designated voltage voltage. The second charge pump charge-pumps the voltage level of the output node to a target charge-pumped voltage level higher than the intermediate voltage level and the designated voltage in response to the detection signal and the first charge pump signal.

  • Publication number: 20090034313
    Abstract: A semiconductor memory device and a layout structure of sub-word line control signal generators. The sub-word line control signal generators are configured to supply a sub-word line control signal of a predefined voltage level to a sub-word line driver to enable a sub-word line of a memory cell array. At least two sub-word line control signal generators are disposed, respectively, at edge areas of the memory cell array, to directly supply the sub-word line control signal to one selected sub-word line driver, thereby reducing the power consumption, including for example, VPP voltage. Embodiments of the present invention also reduce the number of VPP power lines, thereby lessening a noise disturbance.

  • Patent number: 7471108
    Abstract: We describe an input circuit and method. The input circuit includes a variable reference level generator that increases a level of a reference signal in proportion to a time when an input signal transits from a low level to a high level and decreases the level of the reference signal in proportion to a time when the input signal transits from a high level to a low level. An analyzer compares the level of the input signal with the level of the reference signal, determines the level of the input signal, and outputs a signal based on the comparison. The input circuit and method widen the minimum difference between the input and reference signal to facilitate analysis of the input signal.
