摘要： Provided is a method for driving a surface emitting semiconductor laser including an active region that generates light, a resonator structure disposed such that it sandwiches the active region, and a driving electrode that provides power to the active region. The surface emitting semiconductor laser has an internal resistance defined by voltage and current applied to the driving electrode. The method includes applying a modulation signal to the driving electrode, in which the modulation signal has a current amplitude defined by a first current value and a second current value that is greater than the first current value. The modulation signal is in a negative gradient region in which the internal resistance decreases in contrast to the increase of the current.

摘要： The invention provides a display device which is capable of adjusting the image refresh rate to an optimal value regardless of the type of image data, and thus has low power consumption. The display device includes a liquid crystal panel for displaying images, a liquid crystal controller for refreshing images displayed in the liquid crystal panel according to an image data signal, and a CPU for inputting the image data signal to the liquid crystal controller. In the display device, the CPU has a discrimination section for discriminating whether the image data is a moving image or a still image based on an input interval of the image data from the CPU to the liquid crystal controller, and the liquid crystal controller has an image refresh demand signal generation circuit for changing the image refresh rate of the liquid crystal panel based on the result of discrimination by the CPU.

摘要： An audio/video synchronizing system and a monitor apparatus can provide a set of contents where the images and the sounds of the contents show lip synchronization to the user so that the user may not have any strange and uneasy feeling if only the images are transmitted wirelessly. A contents server outputs sounds of a set of contents at a timing delayed by an initial delay time (1 second) that is greater than the transmission delay time according to the PTS and the DTS defined by the contents server by taking the largest transmission delay into consideration. The monitor corrects the time base of the STC added to the video packets according to the transmission delay time and subsequently outputs the images according to the SCR, the time base of which is corrected, and the PTS and the DTS, for which the initial delay time is defined. With this arrangement, it is possible to compensate the delay of the transmission delay time and display the images at a timing synchronized with the timing of outputting the sounds. Thus, it is possible to realize lip synchronization between the sounds and the images if only the images are transmitted wirelessly.

摘要： Disclosed are a back illuminated photodiode array, which is mass-producible and has an ultra-thin high-performance single-sided electrode structure, and a method of manufacturing the same. Both electrodes of a photodiode on a semiconductor substrate 1, which are anode and cathode, are collected on one plane of the substrate. The collection of the electrodes is achieved by electrically introducing one of them to the other plane via a hole H penetrating the semiconductor substrate 1. The semiconductor substrate 1 is thinned by polishing, and thus the time for forming the hole H is shortened. Moreover, during the manufacturing process, a supporting plate 3 is attached to the semiconductor substrate for reinforcing the thinned substrate. Thus, handling of a wafer during the process becomes easy and complies with mass production.
