  • Publication number: 20090010669
    Abstract: The change in an output voltage when a control voltage is changed is calculated, and the change in the control voltage divided by the calculated change in the output voltage is defined as a sensitivity coefficient. The sensitivity coefficient is recalculated for each predetermined time interval or whenever a predetermined condition is satisfied, and the control voltage is corrected based on the recalculated sensitivity coefficient. Example of the predetermined condition include the time of start-up of the apparatus, the time at which the accumulated number of printed sheets reaches a predetermined number, and the time of carrying out process control.

  • Patent number: 7474598
    Abstract: An optical reproducing device is provided with predetermined length mark signal measurement means which measures amplitude values of a 2T mark and an 8T mark, which are a short reproducing power control mark and a long reproducing power control marks, respectively, from information data recorded in an magneto-optical disk. Reproducing power of a light beam is controlled by a laser power control circuit, based on the amplitude values of the 2T mark and the 8T mark. The predetermined length mark signal measurement means detects a specific pattern including the 2T mark from a bit arrangement pattern of the information data, and measures the amplitude value of the 2T mark correponding only to the 2T mark included in the specific pattern. This structure can provide an optical reproducing device which can maintain the reproducing power at an optimum value and reduce the probability of reading errors, without reducing the utilization ratio of an optical recording medium.

  • Patent number: 7474155
    Abstract: A power amplifier includes a front-stage amplifier including first and second transistors connected in parallel, and a rear-stage amplifier including a third transistor. The first transistor is biased into near-Class A without a distortion compensation circuit. The second and third transistors are biased into near-Class B with a distortion compensation circuit. The gain characteristics of the first to third transistors are adjusted so that the concave portion of the gain characteristics of the front-stage amplifier and the convex portion of the gain characteristics of the rear-stage amplifier match each other, to thereby flatten the gain characteristic of the entire power amplifier.

  • Patent number: 7474373
    Abstract: A display element has a arrangement that allows the pixel to have at least two domains in which the medium shows optical anisotropies of different directions when a force (for example, an electric field) is applied or when no force is applied. It is preferable that directions of the optical anisotropies occurred in the respective domains when the electric field is applied respectively have 45 degrees±10 degrees with absorption axes of polarizers, and that the directions of the optical anisotropies occurred in the respective domains when the electric field is applied make 90 degrees±20 degrees.

  • Patent number: 7473014
    Abstract: An LED lamp has a convex lens 3 which has an upper portion 5 and a lower portion 6. An upper curved surface 5A of the upper portion is different in shape from a lower curved surface 6A of the lower portion 6 so as to refract rays of light from an LED chip 2 more strongly than the lower curved surface 6A does. This avoids reflection of incident outside light toward a front and hence prevents misrecognition. An interface plane S1 between the upper and lower portions 5 and 6 of the convex lens 3 is located on an upper end face 2A to thereby prevent collection of outgoing light upon the interface plane S1 and generation of an irregular emission peak at the front.

  • Patent number: 7474293
    Abstract: A liquid crystal display apparatus drives an active-matrix liquid crystal panel by the use of the line reversal driving method. To do so, a common driver AC-drives one of a pair of electrode in each of all the pixels of the liquid crystal panel. An adding circuit obtains the sum of a plurality of gradation components for deciding the gradations of the pixels in one of the columns in the liquid crystal panel at intervals of the predetermined horizontal period. A voltage setting portion in a source driver corrects a reference voltage difference ?Vref on the basis of the sum at intervals of the horizontal period, divides the corrected reference voltage difference ?Vrefa, decides a plurality of gradation voltages, and selects voltages to be applied to a plurality of data lines in the liquid crystal panel from among the gradation voltages based on the plurality of gradation components. The selected plurality of voltages are applied to the plurality of data lines.

  • Patent number: 7474305
    Abstract: Each signal line enters a preliminary polarity inversion period prior to a normal polarity inversion period so as to be inverted to the opposite polarity. By the preliminary polarity inversion a signal line on a border of blocks experiences a potential hike and the potential oscillates, which, however, is restored later by the application of a correct potential in the normal polarity inversion period. When transferring data per block, the problem of different potential states between the border of the blocks and an area surrounding it, which is caused by the potential oscillation of the signal line on the border of the blocks, is relieved.
