Title: Line duplicate system
Inventor: DAIMON FUMIO
IPC: H04B10/032
Filed: 1990-09-06
Abstract: PURPOSE:To make the line in duplicate with an opposite terminal station only by dividing a transmission signal into n:1, sending the result to an active line 1 and a standby line 2 respectively, allowing a reception section to add both signals, adjusting the level automatically and outputting the result. CONSTITUTION:Photocouplers 241, 242 distribute an optical output of optical transmission sections 221, 222 into n:1 (n<1) and send them to an active line 26 and a standby line 27. Moreover, photocouplers 251, 252 superimpose an optical signal of the active line 26 and an optical signal of the standby line 27 and input the result to optical reception sections 231, 232. An optical/electric conversion circuit (O/E) 31 of the optical reception section converts an input optical signal into an electric signal, an automatic gain adjustment (AGC) circuit 32 applies automatic gain control to the electric signal input from the O/E 31 to generate an output. An identification circuit 33 identifies an output signal from the circuit 32 and generates an output. Since the signal level of the active line is larger than the signal level of the standby line by a multiple of (n), the signal of the active line is identified independently of the signal of the standby line by selecting a threshold level for identification in the circuit 33 to be a value between the signal level of the active line and the signal level of the standby line.

Title: Stray light removing device for raman spectroscopic analysis
Inventor: HIRANO YUKARI
IPC: G01N21/65
Filed: 1985-10-23
Abstract: PURPOSE:To measure a Raman spectrum by a single monochrometer spectroscope and to reduce the cost and size of a device by remove stray light due to laser reflected light without decreasing Raman scattered light. CONSTITUTION:The Raman scattered light 4 is reflected repeatedly four times and returned to the same position with the optical axes of laser reflected light 3 generated by a sample 2 and the Raman scattered light 4 through a couple of right-angled prism 8 to form an image on a spectroscope incidence slit 10 through a condenser lens 9. Narrow band-pass filters 6 and 7 become maximum in the transmissivity of laser light at a specific angle of incidence of <=30 deg. and when the transmissivity of the laser reflected light 3 is 90% and the reflection factor to the Raman scattered light is 95%, the Raman scattered light 4 is attenuated by only 20% although the laser reflected light 3 is attenuated by 10<-4>. Consequently, only the laser reflected light which is the cause of stray light is removed sufficiently. Further, the optical axis of the Raman scattered light is returned to its original axis by using the prisms 8 and 8', so the position of the spectroscope need not be adjusted even when a measurement is taken by using a conventional multiple monochrometer.
