    • An automatic testing apparatus includes an expert rule which is derived from expert knowledge and defines a tree of successively traceable nodes interconnected by decision branches which lead to a plurality of fault modes. Each of the nodes defines a particular test pattern and a corresponding expected value. One of the nodes is specified and a test pattern defined by the specified node is applied to an LSI chip under test and a result signal is derived therefrom. This result signal is compared with the expected value defined by the specified node to produce a comparison result. The tree of the expert rule is traced from the specified node to a subsequent node according to the comparison result and the subsequent node is specified instead of the previously specified node. The process is repeated as the tree is traced from one node to another until one of the fault modes is reached to identify a chip failure.
    • 自动测试装置包括从专家知识导出的专家规则,并且定义通过导致多个故障模式的决策分支互连的连续可跟踪节点的树。 每个节点定义特定的测试模式和相应的预期值。 指定其中一个节点,并将由指定节点定义的测试模式应用于被测试的LSI芯片,并从中得到结果信号。 将该结果信号与由指定节点定义的期望值进行比较以产生比较结果。 专家规则的树根据比较结果从指定的节点追溯到后续节点,指定后续节点,而不是先前指定的节点。 当树从一个节点追溯到另一​​个节点时,重复该过程,直到到达一个故障模式来识别芯片故障。

    • In a sound signal playback machine and method thereof, predetermined high frequency components are extracted from sound signals SL to SC of a main channel by high frequency pass filters 21 to 25, and these high frequency components are respectively played back by speakers. At the same time, predetermined low frequency components are extracted from sound signals SL to SC of the main channel by low frequency pass filters. These low frequency components and sound signal SLFE exclusively used for the low frequency band are added to each other, and the thus obtained addition signal is played back by the speaker 66. In this case, the degree of the low frequency pass filters is set higher than the degree of the high frequency pass filters, and the high frequency component is delayed.
    • 在声音信号播放机及其方法中,通过高频带通滤波器21〜25从主声道的声音信号SL〜SC提取预定的高频分量,这些高频分量由扬声器分别回放。 同时,通过低频通滤波器从主通道的声音信号SL到SC提取预定的低频分量。 专门用于低频带的这些低频分量和声音信号SLFE彼此相加,并且所得到的相加信号由扬声器66重放。在这种情况下,低通滤波器的程度被设置得更高 比高频率滤波器的程度高,并且高频分量被延迟。

    • Based on searched route information and map data, a target intersection for guidance is specified. For the specified target intersection, lane data regarding the number of lanes and lane control of roads being connected thereto is read, and then recommended lane information which indicates which lane to take when entering the target intersection and to exit therefrom is generated. Based on information about the target intersection and the lane data, a simplified intersection image of the target intersection for lane guidance is generated. Based on the recommended lane information, a running path which passes through the recommended lanes for entering into and exiting from the target intersection is generated, and is combined with the intersection image. Then, lane guidance information for displaying the resultant intersection image is outputted with a predetermined timing. As such, guidance can be visually made on a screen indicating which lanes to take to enter into and exit from the intersection.
    • 基于搜索到的路线信息和地图数据,指定用于引导的目标交叉点。 对于指定的目标交叉路口,读取关于与其连接的道路的车道数和车道控制的车道数据,然后生成指示进入目标交叉路口并从其出口时要采取哪条车道的推荐车道信息。 基于目标交叉点和车道数据的信息,生成车道引导目标交叉点的简化交叉图像。 根据推荐的车道信息,生成通过推荐车道进入和离开目标交叉路口的行驶路径,并与交叉路口图像组合。 然后,以预定的定时输出用于显示所得交叉路口图像的车道引导信息。 因此,可以在屏幕上可视地指导指示进入和离开交叉路口的通道。
