    摘要： The dropout detection circuit of the invention includes: a high-speed envelope detection circuit for detecting an envelope of a reflection signal of a light beam with a first time constant; a low-speed envelope detection circuit for detecting an envelope of the reflection signal with a second time constant larger than the first time constant; a differential circuit for generating a difference signal indicating the difference between the envelopes detected by the envelope detection circuits; and a comparator for converting the difference signal to a binary value according to a predetermined binary criterion. The high-speed envelope detection circuit makes the first time constant larger during recording than during reproduction, to enable stable dropout detection irrespective of during reproduction or during recording.

    摘要： A precedent database is generated by registering location indicating information that shows location of each of a plurality of precedent data. A knowledge database is generated by repeating processes of carrying out a search of this precedent database according to a specified condition formula and registering knowledge names representing results of the search in correlation with the condition formula. Component and failure names in the knowledge database are inserted as items of a generated FMEA sheet. Items of the FMEA sheet are specified and displayed such that corresponding text data can be referenced.

    摘要： A demodulator for modulated RF signals comprises a passive four port structure (1). The four port structure (1) has a first input (3) for supplying a modulated RF signal to be demodulated. A second input (2) is supplied with a RF signal from a local oscillator (21). Two output terminals are connected to power sensors (4, 5). The RF signal from the local oscillator (21) is supplied to the second input (3) of the four port structure (1) without being RF switched by an RF switch. The demodulator is particularly useful for modulation schemes with a finite number of magnitude states (nQAM modulation).
