Title: Optical signal receiving equipment
Inventor: ITSUSHIKI NORIO
IPC: H04B10/40
Filed: 1981-06-11
Abstract: PURPOSE:To obtain a receiving circuit which can deal with wide range variation of level caused by bias of coupling loss of optical fiber connectors, etc. CONSTITUTION:An optical signal transmitted through an optical fiber which is not shown in the diagram is converted into an electric signal at a light receiving section 1, and the electric signal is supplied to the (+) terminal of an operational amplifier for discriminating reception 16 through an amplifier 4. On the other hand, a part of the said electric signal is supplied to the (+) terminal of an operational amplifier 12 in a max. value-min. value detecting circuit section 5. Therefore, the minimum value of the received signal is stored in a condenser C7 and the maximum value is stored in another condenser C8. Both the stored voltages are averaged (1/2) by resistances R11 and R12, and supplied to the (-) terminal of the operational amplifier 16 mentioned above as a threshold voltage through an operational amplifier 14. Moreover, when the received signal level becomes lower than a prescribed value by an operational amplifier 15, a squelch signal is obtained from a terminal 10.

Title: Optical amplifier
Inventor: OISHI YASUTAKE
IPC: H01S3/17
Filed: 1994-04-26
Abstract: PURPOSE:To suppress ' gain fluctuation or noise production of an optical amplifier resulting from the hourly fluctuation of the excited light outputting intensity of the amplifier by inserting a light reflecting body into at least wither one of the input and output terminals of the amplifying medium added with rare- earth elements of the amplifier. CONSTITUTION:An optical amplifier amplifies light by using a fluoride optical fiber, the core of which is added with such rare earth elements as Pr and Yb, as an amplifying medium. Namely, light is multiplexed by optically coupling a semiconductor laser l for excitation and semiconductor laser 2 for optical signal with a photocoupler 3 and the multiplexed light is made incident to the fiber 5 for amplification composed of a substance added with the rare earth elements. The fiber 5 is optically coupled with the photocoupler 3 by inserting light reflecting bodies 4 and 6 into the end faces of the fiber 5 and, at the same time, with the pigtail 7 of the fiber 5. The output of the pigtail 7 is monitored by means of a light spectrum analyzer 8. Consequently, such an optical fiber amplifier that the intensity of excited light from the amplifier does not vary and, therefore, the gain the amplifier does not vary can be obtained.

Abstract: PURPOSE:To remove easily, economically and efficiently COD from water contg. bisulfite to be discharged from a reverse osmosis membrane separator for desalting by dispensing an alkali agent to said water under aeration of said water. CONSTITUTION:Condensate is introduced into the 1st tank 1a and the pH thereof is measured with pH 6a, and if the pH decreases to <4, a pump 7a is started to supply an alkali agent via a pipe 8a to the water to adjust the pH to 4-7 and to treat the water for 5-10min. The water is then introduced into the 2nd tank 1b, where the water is treated for 60-120min under the condition of 4-7pH to oxidize most of the bisulfate in the water. The treated water is introduced into the 3rd tank 1c, where the pH is maintained in a 6-8 range and the residual bisulfite ion and sulfite ion are finally treated to make the treated water match the level of the release water. The water in the tank 3 is stagnated for 5- 30min. COD is thus considerably reduced and the treated water is released from the 3rd tank to the outside of the system.

Filed: 1994-04-06
Abstract: PURPOSE:To recognize even time-series variation of individual items in a Pareto graph by selecting data of a desired item in the Pareto graph while the Pareto graph is displayed, and displaying a trend graph based upon the time-series data of the item. CONSTITUTION:When the trend graph is displayed so as to see time variation of a defect A, the part showing the defect A is selected by arranging a painter 10 in the Pareto graph (a). Consequently, the display screen is switched to the trend graph showing the generation state in a specific period of the defect A, for example, between May 1st and May 16th as shown by (b). Here, a hair line cursor 11 in the trend graph is moved to the position of May 10th to select the date, and then the display screen is switched to a Pareto graph of May 10th as shown by (c). Thus, the trend graph showing the time variation of desired data is displayed in the display state of the Pareto graph to easily recognize the information.

Title: Elimination device for inter-code interference by decision feedback
Inventor: KANEMASA AKIRA
IPC: H04B3/06
Filed: 1986-04-18
Abstract: PURPOSE:To eliminate even the interference occurring within a symbol waveform by using two types of one-tap adaptive filters. CONSTITUTION:It is possible to extract only the residual inter-code interference component with a certain positive probability excepting for zero by obtaining the sum of or the difference between the present sample value and that used before MT seconds (M: an integer, T: a data period) in terms of a differential signal ( received signal containing the residual inter-code interference compo nent). Therefore said sum or difference is used as an error signal and the up- date of coefficients is carried out only when said interference component is correctly extracted. Thus the adaptive working of an adpative filter 25 is se cured. While the artificial inter-code interference signals produced by adaptive filters 18 and 20 are supplied to a subtractor 2 via adders 21 and 22 and then subtracted form the received signals undergone the inter-code interference. Thus it is possible to eliminate the component caused by the interference occur ring within a symbol waveform.
