Title: Optical receiver
Inventor: SAEKI NAOTO
IPC: H04B10/2507
Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To provide an optical receiver immune to noise with less coupling distortion for converting optical signals modulated by frequency multiplex signals to electric signals. SOLUTION: The received optical signals are provided with orthogonal polarization components and the light of the respective polarization components is modulated by mutually different information signals. Such optical signals are separated for the respective polarization components by a polarization separator 13 and converted into the electric signals respectively in first and second optic/electric conversion means 16 and 17 and the electric signals after conversion are amplified in respective amplifiers 18 and 19. The one for which the output of the amplifiers 18 and 19 is coupled to one electric signal is outputted as an output signal. Thus, since separation is performed for the respective polarization components and light reception and amplification are performed, the coupling distortion is reduced.  Also, since the light intensity of the respective polarization components is not lowered before and after being separated even when the separation is performed for the respective polarization components, noise characteristics are not degraded by the separation.

Title: Treatment of raw urine and clarification tank sludge
Inventor: KITAMURA AKIRA
IPC: C02F3/28
Filed: 1978-03-16
Abstract: PURPOSE: To treat raw urine economically and efficiently by separating the raw urine from clarification tank sludge, treating the urine in aerobic or anaerobic condition, and treating the sludge by flocculation dehydration with use of a cationic flocculant.  
     CONSTITUTION: The sludge taken from a clarification tank is divided into raw urine and clarification tank sludge through the measurement of chlorine concentration. The raw urine is treated in aerobic or anaerobic condition, while the sludge is treated by flocculation-dehydration with use of a cationic floccuant; the both treated liquids are combined together and subjected to an activated sludge treatment. The use of the cationic flocculant reduces the BOD of the sludge treated water to below 500 ppm and enables the combination of the water with urine treated water for activated sludge treatment. The dehydrated cake formed from the clarification tank sludge may be turned into compost which can be used as a soil improver.
