Title: Optical receiver
Inventor: FURUTO YOICHI
IPC: H04B10/60
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To provide an optical receiver reducing the influence of optical fiber distributing effect upon light reception sensitivity by bisecting the spread of wavelength spectrum of the optical signal into light on the side of long wavelength and light on the side of short wavelength at the central value of the spectrum. SOLUTION: With a certain wavelength as a border, a light discriminator 1 outputs optical signals while dividing an optical signal with the component having long wavelength to a long wavelength output terminal 9 and an optical signal with the component having short wavelength to a short wavelength output terminal 10. In this case, the wavelength to be this border is set so as to be the center of the spread of the optical wavelength spectrum W. Then, the bisected optical signals are respectively converted to voltage signals by different photodiodes 2 and 3 and preamplifiers 4 and 5 and differentially inputted to the same equivalent amplifier 6. The equivalent amplifier 6 amplifies the input signal to the desired voltage signal.  Then, a clock extraction/data identification circuit 7 extracts a clock component from the output of equivalent amplifier 6, identifies data and outputs a clock signal and a data signal.

Abstract: PURPOSE: To manufacture simply and economically an adsorbing agent of lone life- time having high selectivity for heavy matallic ions, especially for mercury ions, and a large adsorbing capacity, by adsorbing, aq. acidic soln. of thiocarbohydrazide with activated carbon.  
     CONSTITUTION: Thiocarbohydrazide is dissolved in an inexpensive aq. soln. of sulfuric acid (pH 1W4) and is adsorbed by activated carbon, pref. by coconut shell activated carbon, at a temp. 50W90°C. The amount of adsorbed thiocarbohydrazide is nearly 5W20% by weight. The activated carbon is washed with water, and is dried to produce an adsorbing agent having high selectivity and high adsorbing capacity especially for mercury. Even when the adsorbing agent comes into contact with water, thiocarbohydrazide is hardly dissolved, consequently the adsorbing agent is characterized by long service-life compared with conventional adsorbing agent, and is used effectively for removing heavy metals contained in the industrial waste water.
