    摘要： A plurality of electric data signals representing parallel data bits are applied to a plurality of gates or control terminals on-off controlling optical switches, respectively. A single pulsed synchronizing signal is distributed to input terminals of the plurality of gates or the optical switches. Synchronizing signals, which have passed through gates or optical switches, which are in an ON state, among the plurality of gates or the optical switches are coupled to synchronize finally an optical signal. In this way a serial optical pulsed output signal can be obtained by utilizing optical delay in a process for distributing the synchronizing signals or a process for coupling the synchronizing signals.

    摘要翻译： 表示并行数据位的多个电数据信号分别被施加到多个门或控制端开关控制光开关。 单个脉冲同步信号被分配到多个门或光开关的输入端。 多个门或光开关之中已经通过栅极或光开关的处于ON状态的同步信号被耦合以使光信号最终同步。 以这种方式，可以通过在用于分配同步信号的处理中利用光学延迟或者用于耦合同步信号的处理来获得串行光脉冲输出信号。

    摘要： A plurality of sub word lines each have a length equivalent to the division of a main word line along the extension direction thereof, arranged along a bit line crossing said main word line, and are connected with a plurality of memory cells. A first sub word select line arranged in parallel to the main word line is extended to a plurality of sub arrays arranged in the extension direction of the word line. A second sub word select line is connected to the corresponding one of said first sub word select line to be extended orthogonally to a word line driving circuit area of an adjacent sub array. In the sub word line driving circuit provided for each sub array, a sub word line is selected and deselected by signals supplied from said main word line and said second sub word select line.

    摘要： A wide-angle lens is disclosed that includes a front lens group and a rear lens group that are arranged in order from an object side to an image side with an aperture being arranged between the front lens group and the rear lens group. The front lens group includes at least two lenses arranged toward the object side that have negative powers, and at least one lens arranged toward the image side that has a positive power. The rear lens group includes at least one lens having a positive power. One of the lenses of the front lens group arranged second in order from the object side has a lens face that is arranged into an aspheric surface. The front lens group, the aperture, and the rear lens group make up an image forming system having an angle of view greater than 180 degrees.

    摘要： A vehicle environment recognition apparatus includes stereo-image taking means for outputting a reference image of the surroundings of a subject vehicle, stereo matching means for correlating a parallax with each pixel block in the reference image by stereo matching, preceding-vehicle detecting means for detecting a preceding vehicle from the reference image on the basis of the parallax or the like, and smear determining means for searching a pixel column vertically extending in the reference image for brightnesses of pixels, the pixel column including a pixel block having a parallax less than or equal to a long-distance parallax threshold value corresponding to the long distance including infinity, and determining that a smear occurs when a ratio of the number of pixels having brightnesses more than or equal to a predetermined brightness to the total number of pixels in the pixel column is more than or equal to a predetermined ratio.

    摘要： A feature video image vdt and a thumbnail picture sdt read from a receiving section C10 are recorded onto a mass storage medium M1, and meta information mdt is recorded into a high-speed storage unit C12. Semantic browser means C1 extracts a partial video image from the feature video image on the basis of the meta information mdt so as to organize a preview video image, and also displays a semantic graph and a current position on the screen on the basis of the meta information and replays the feature video image or the preview video image from that position when there is a position designation input. Furthermore, when there is a browsing instruction input, the semantic browser means C1 carries out browsing between the feature video image and the preview video image, or browsing within the feature video image or within the preview video image. An accounting section C18 carries out accounting processing.
