Title: Method for monitoring amount of flocculant to be added and device therefor
Inventor: TOTOKI TOSHIO
IPC: B01D21/30
Filed: 1993-12-09
Abstract: PURPOSE:To optimize the amt. of a flocculant to be added by arranging a heater and temp. sensors in a passage, detecting the temp. rise of each sensor when the heater is pulse-energized and contrasting the temp. rises. CONSTITUTION:A heater 3 is arranged in a passage 4, and two temp. sensors 1 and 2 are provided on the downstream side at a distance from each other. A flocculant is added to the excess activated sludge, and the dehydrated filtrate flows down in the passage 4. The heater 3 is pulse-energized, the heat of the heater 3 is diffused into the boundary layer by conduction, and the temps. detected by the sensors 1 and 2 are maximized. At this time, even if the amt. of flocculant added is too much or too little, the viscosity of the flocculated liq. is increased, the boundary layer develops, and hence the difference in maximum temp. between the sensors 1 and 2 is reduced. Accordingly, whether an optimum amt. of the flocculant is added or not is judged by monitoring the temp. difference.

Title: Fixing method for spherical microlens
Inventor: KONDO NOBUYOSHI
IPC: G02B6/32
Filed: 1988-12-07
Abstract: PURPOSE:To improve the performance of optical coupling by pressing the spherical microlens in the center part of a cross groove and fixing the spherical microlens so that the spherical microlens is pressed by four parallel edge parts of the cross groove which face an axis of symmetry. CONSTITUTION:The cross groove 4 is easily formed by a cutting machine used to cut a semiconductor wafer and optical crystal with high accuracy. The machining accuracy is less than several mum and center axis deviation accuracy which is about 1/10 as large as that of a cylindrical hole formed by a conventional drill machining method. Further, when the spherical microlens 1 is inserted into a lens holder part 8, four edge parts and the spherical surface contact each other at four points, so the insertion pressure is reduced greatly, thereby fixing the spherical microlens extremely stably by the intrusion effect of the edge part. Consequently, the spherical microlens 1 can be fixed strongly to the lens holder part 8 with the small insertion pressure, so the performance of the optical coupling is improved.
