Title: Treatment of phosphorus-containing waste water
Inventor: UENO SUSUMU
IPC: C02F1/44
Filed: 1986-10-13
Abstract: PURPOSE:To permit easy removal of phosphate and metal hydroxide from treated water by using an ultrafilter to separate phosphate- and metal hydroxide- contg. sludge from the treated water. CONSTITUTION:Phosphorus-contg. waste water is biologically treated by activated sludge in a biological reaction vessel 1 and the activated sludge is separated from the treated water after the biological treatment in a flotation thickening vessel 2. The treated water after the sludge sepn. is fed into a reaction vessel 3 where a reacting agent to form the insoluble phosphate by reacting with the phosphate ions contained in the treated water (e.g., ferric chloride, alum) is incorporated into the water. The metal-component in the unreacted reacting agent remaining in the treated water is thereafter converted to the insoluble metal hydroxide by the incorporation of an alkali into the water. THe sludge contg. said phosphate and metal hydroxide is separated from the treated water by a solid-liquid sepn. and is returned to the vessel 1. The sepn. of the phosphate- and metal hydroxide-contg. sludge from the treated water is executed by the ultrafilter 5. As a result, the removal of the phosphate and metal hydroxide from the treated water is facilitated.

A repeater of the system having each polarized signal is provided with phase synchronization oscillators 112, 115, 123, 127 driven by reference frequency oscillators 113, 124 and applying the transmission and reception local signals to each section, and the transmission local signal and the reception local signal in the repeater are locally synchronized respectively. The regenerative relay station uses waveform equalizers 139, 140 and cross polarized wave interference compensation devices 141, 142 to compensate the interference noise generated in the non-regenerative relay station 145 altogether.

Title: Camera
Inventor: TAKACHI TAIZO
IPC: H04N5/351
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To prevent a color filter from discoloring with intense light without providing a stop mechanism for a camera using as an image pickup means a color solid-state image pickup element with an on-chip color filter. SOLUTION: A dimming element 11 is provided in the optical path along which the light from a subject side reaches the color solid-state image pickup element 4. In this case, when intense light is made incident, the dimming element 11 reacts and automatically adjusts the light quantity, so the on-chip color filter 5 can be prevented from discoloring without providing any stop mechanism. Thus, no stop mechanism is needed, so a driving actuator is not necessary and then a movable part is not needed either. The necessary mechanism, therefore, becomes simple and the cost of the camera is reducible although the discoloration of the color filter can be prevented.
