  • Publication number: 20140118040
    Abstract: A synchronizing circuit that is capable of generating a reproduced clock signal synchronized with a reference clock signal without causing a false lock and a clock data recovery circuit including the same are provided. To generate a clock signal synchronized with a reference clock signal associated with a data transition point that appears every predetermined period in an input data signal, the following false-lock avoidance processing is performed. That is, precharging of a first line is started when a phase control voltage applied to the first line by a charge pump falls below a lower-limit reference voltage, and the precharging of the first line is continued until the phase control voltage exceeds an upper-limit reference voltage.

  • Publication number: 20140020375
    Abstract: A hydraulic working machine has an assist electric motor connected to an engine and a hydraulic pump. The emissions of air pollutants in the exhaust gas from the engine are minimized regardless of fluctuations in the load torque of the hydraulic pump. A specific revolution speed suitable for reducing the emissions of air pollutants is stored, and an engine is controlled using the specific revolution speed as a target revolution speed. The absorption torque of a hydraulic pump is subjected to high-pass filtering whereby a high-frequency component devoid of a trend component is obtained. Target assist torque is computed from the high-frequency component, and the assist electric motor is subjected to power running/generation control accordingly. A specific output torque range suitable for reducing the emissions of air pollutants is stored, and the target assist torque is corrected so that the trend component does not exceed the specific output torque range.

  • Patent number: 8633885
    Abstract: A display panel driving apparatus supplies pixel driving potentials corresponding to pixel data to the source lines of a display panel. The pixels are located at the intersections of the source lines and a set of scanning lines. For each pixel, the driving potentials are alternately positive and negative with respect to a common reference potential supplied to the display panel. While the display driving apparatus is latching the pixel data for the pixels on each scanning line, the output circuits of the display driving apparatus are disconnected from the source lines, allowing the source lines to return to the common reference potential, thereby avoiding unwanted current flows in the output circuits and unwanted distortion of the pixel driving waveforms.

  • Patent number: 8586854
    Abstract: A thermoelectric conversion element is configured to have two types of conductors with different Seebeck coefficients physically connected alternately with an electrode via one or more electrical resistance layers formed by electrical resistor having electrical resistance rate of 1×10?3 ?cm or more. This arrangement enables charges to be generated by the difference of temperature in both ends of the element and to be densely stored in the electrical resistance layers formed by electrical resistor. Moreover, it is thought that thermal energy equivalent to the difference of temperature is input into the electrical resistance layers and that electromotive force increases as a result of an increase of output voltage.
