Title: Monitoring device for optical fiber switch
Inventor: WASHIO HIDEKI
IPC: H04B10/079
Filed: 1981-03-31
Abstract: PURPOSE:To confirm whether a switch itself in use is normal or abnormal, by mechanically interlocking optical fibers for monitoring fitted to optical fibers for an optical transmission line, and then monitoring their operation conditions. CONSTITUTION:An optical fiber main electrode 5 for monitoring is fitted to a main electrode 2 for an optical transmission line of an optical fiber switch 1 which change the connection states of an optical fiber cable 4, and an optical fiber slave electrode 6 for monitoring is fittd to the slave electrode 3, so that the main electrodes 2 and 5 perform the same operation. Under the light emission command of a light signal receiver 11, a power source 12 powers up an element 8. Then, about 50% of light transmitted through a semitransparent mirror 10 is sent as a monitoring signal to the main electrode 5 and passed through the gap of a coupling part to be photodetected by the slave electrode 6, so that it is sent to a photodetecting element 9. On the other hand, about 50% of light reflected is sent as a reference signal to another photodetecting element 9. They are converted into electric signals, which are passed through amplifiers 13 and compared 14, thereby outputting the coupling-state confirmation signal of the optical switch 1.

Title: Monitoring circuit for standby side
Inventor: FUJINAGA SEI
IPC: H04B1/74
Filed: 1989-02-28
Abstract: PURPOSE:To improve the monitor detection performance by connecting filter circuits having 2 kinds of different time constants in parallel with a feedback section of an AGC amplifier and selecting the filter circuit with a smaller timer constant at the input of a monitor signal of a standby side monitoring circuit. CONSTITUTION:When an on-set logic is outputted to a signal line 103 through which on-line information is transmitted, a 1st filter circuit 2 having a large time constant is selected for a feedback circuit while a selector 4 is switched interlocking with a switch 6. When an offset-logic is outputted to the signal line 103, an off-line data is inputted from a signal line 102 is inputted to an AGC amplifier 1 and a 2nd filter circuit 3 with a small time constant is selected by the selector 4. Thus, since the reply time of the loop system is fast at production of changeover and the time required for the leading of the monitoring signal is small, it is possible to decrease the mask time of monitoring required at the time of switching.

Title: Guiding device having speech recognition function
Inventor: IWAMOTO SHINICHI
IPC: G10L15/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To improve the performance of speech recognition and to improve convenience to use by reducing the number of vocalization for speech recognition. SOLUTION: A signal undergoes speech recognition processing in a speech processing part 2 and recognition results are given to a CPU 1 as a numeric value. The CPU 1 retrieves a word dictionary transition table 4 based on the recognition results, selects a dictionary to be used next from a word dictionary storing part 3 and sends it to the part 2. Also, it outputs guidance that urges vocalization to input a needed signal. Since a user inputs the next speech in accordance with a guidance output, the needed signal is inputted and it can easily be identified even if the same word exists plural times in a word dictionary.
