摘要： Optical signals inputted to input ports are split in half by 1×2 optical splitters respectively and the resulting signals are inputted to the input terminals of an optical matrix switch. The optical matrix switch switches between the routes of the individual optical signals and outputs the signal at any of the output ports. This enables the optical signal from the same input port to be outputted at two different output ports, which makes it possible to effect “bridge” at the time of protection switching.

摘要： In a digital signal time-division multiplex apparatus according to the present invention, digital signals transmitted through a plurality of channels are converted into low-order section frame signals in response to sync signals by low-order section frame processing boards provided for their respective channels. The low-order section frame processing boards are arranged in parallel on a mother board at regular intervals. The low-order section frame signals processed by the low-order section frame processing boards are supplied to a high-order section frame processing board and sequentially selected within one frame, thereby generating time-division multiplex signals. The sync signals are generated by a sync signal generating board and transmitted to a sync signal transmitting line formed on the mother board. The sync signal transmitting line is formed so as to transmit the sync signals in a direction in which the low-order section frame processing boards are arranged. The sync signals are supplied to the low-order section frame processing boards through the sync signal transmitting line in a bus line system. The low-order section frame signals generated from the low-order section frame processing boards are transmitted to a plurality of low-order section frame signal transmitting lines formed in the direction in which the sync signals are transmitted, and supplied to the high-order section frame processing board through the low-order section frame signal transmission lines.

摘要： A speech recognition apparatus includes a storage medium for storing tree structured dictionary data containing words as nodes in a tree structure with a root and leaf nodes. An input speech is compared with a forward acoustic model corresponding to a speech resulting from chronologically reproducing words indicated by nodes for leaf nodes. A backward speech is further compared with a backward acoustic model. The backward speech is generated by reproducing the input speech in chronologically backward order. The backward acoustic model corresponds to a speech resulting from reproducing a word string toward the root in chronologically backward order. The comparison is performed in the backward order of a sequence starting from one of separator nodes. The speech recognition apparatus thereby outputs a word string that highly likely matches the input speech.

摘要： An oxygen sensor has a detecting device unit for outputting a sensor current such as a limiting current of which a value is constant even though a sensing voltage applied to the oxygen sensor changes in a limiting current generating region and corresponds to an air-fuel ratio of a combustion gas and a heater for heating the detecting device unit to keep a resistance of the detecting device unit even though the oxygen sensor is degraded. When the sensing voltage is changed to a second sensing voltage of a resistance governing region, a current peak occurs in the sensor current, and a peak current value is detected. Because the peak current value decreases as the oxygen sensor is gradually degraded, when the peak current value is lower than a degradation judging value, it is judged that the oxygen sensor is degraded. Therefore, the diagnosis of the degradation of the oxygen sensor can be performed with a high accuracy.
摘要翻译：氧传感器具有检测装置单元，用于输出传感器电流，例如其值恒定的限制电流，即使施加到氧传感器的感测电压在极限电流产生区域中变化，并且对应于空燃比用于加热检测装置单元以保持检测装置单元的电阻的燃烧气体和加热器，即使氧传感器劣化。当感测电压变为电阻控制区域的第二感测电压时，传感器电流发生电流峰值，并检测峰值电流值。由于峰值电流值随氧传感器逐渐劣化而降低，所以当峰值电流值低于劣化判定值时，判断为氧传感器劣化。因此，能够高精度地进行氧传感器的劣化的诊断。
