    摘要： An optical receiving circuit 1 is composed of a preamplifier circuit 2, an output differential amplifier 3 and a mean value holding circuit 4. The optical receiving circuit 1 is connected to a photodetector 5 for receiving an input optical signal and outputting current. For the preamplifier circuit 2, a transimpedance type circuit may also be used. The preamplifier circuit 2 comprises a feedback resistor 21 and a resistor for detecting output voltage 22, the transimpedance gain is 55 dB &OHgr; and 3 dB bandwidth when the photodetector 5 the capacity of which is 0.2 pF is connected to its output is 8 GHz. The output differential amplifier 3 discriminates and regenerates data by regulating reference voltage Vref between the high level and the low level of the amplitude of an input signal. The mean value holding circuit 4 includes a sample-hold circuit 41 and capacity 42 for holding the mean value of voltage output from the preamplifier circuit 2. As a CR time constant based upon the capacity 42 and the resistor for detection 22 is 1 ns., the mean value level of a received signal can be detected in approximately one byte of the data of 10 Gb/s. The sample-hold circuit 41 samples the detected mean value level according to a sampling pulse from an external device and holds it. The output of the sample-hold circuit 41 is used for the reference voltage of the differential amplifier 3.

    摘要： The attachment structure for attachment of a component to an article in two postures includes a case as the article and the component. The case includes a pair of guide portions, first locking arms and a second locking arm. The component includes a slide portion between the guide portions, a stopper arranged in an end of the slide portion and formed in a size which is not able to insert stopper between the guide portions. The first locking arm is engaged where the slide portion is inserted in a space between the guide portions from one end and slides toward an other end. The second locking arm is engaged where the slide portion is inserted in the space between the guide portions from the other end in a posture opposite to that in which the slide portion is inserted between the pair of the guide portions from the one end.
