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： 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： A/F ratio sensor includes an element portion using a solid electrolytic layer, and generates a sensor current in proportion to an oxygen concentration in an exhaust gas when a voltage is applied thereto. A bias control circuit switches the voltage applied to the A/F ratio sensor to an element resistance detection voltage during an element resistance detection with a given time constant, and detects the sensor current flowing at that time. A comparing circuit detects an amount of voltage change reaching a given value. A timing decision circuit decides a detection of voltage and current changes during the decision timing of the comparing circuit. A data output circuit measures the current change relative to the voltage change in response to the timing decision of the timing decision circuit. In this apparatus, the voltage change and the current change are detected when the applied voltage, which change with the given time constant, reaches to the given reference voltage Vref. In other words, the amount of the current change &Dgr;I of the sensor current is detected before the voltage, which change with the given time constant, converges to the voltage V0.
