Title: Biological treatment of waste water
Inventor: KIMOTO KAZUO
IPC: C02F3/08
Filed: 1980-05-30
Abstract: PURPOSE: To strip fat microbes efficiently from particles by forming the ascending flow and descending flow circulating in a device, supplying high-concn. oxygen to the descending flow and making the velocity of the descending flow higher than the ascending velocity of oxygen bubbles.  
     CONSTITUTION: A cylindrical partition wall 3 is disposed at the center of a waste water treating tank 1, and waste water 5 and high-concn. oxygen 7 are supplied into the descending flow part 9 in the wall 3. The microbes which are stuck on particles such as sand, active carbon or coke are beforehand held afloat across from the top end part of the wall 3 or from slightly below the same to the bottom of the tank 1, in the space sandwiched by the tank 1 and the wall 3, thereby forming fluid layers. The waste water having absorbed oxygen in the descending flow part gives BOD components to the microbe-stuck particles in the ascending flow part. The particles stuck with the grown and fat microbes go beyond the top end of the wall 3, and are included in the descending flow, by which part of the microbes are stripped by fluid shearing forces.

Title: Apparatus and method for processing sonar signal
Inventor: TAKEI MANABU
IPC: G01S7/526
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To easily detect an echo signal from a target in a reverberation level, by a method wherein a wide-band signal is separated into a plurality of narrow-band signals and time-series waveforms in respective bands are arranged in all bands. SOLUTION: A wave transmitter 1 transmits a wide-band pulse signal. When a target exists on the bottom of the sea or near the surface of the sea, a wave receiver 2 receives an echo signal from the target together with a reverberation signal which is scattered on the bottom of the sea or on the surface of the sea. A wide-band signal which is amplified and phase-processed by a preprocessing part 3 is separated into a plurality of narrow-band signals by a frequency analytical part 4. A detection part 5 converts the respective band signals into waveform data which indicates a change in a time-series level. Then, an average processing part 6 synchronizes the waveform data in all the band signals so as to be added and averaged. It finds waveform data indicating a change in an averaged time-series level in all the band signals.  Among the found waveform data, a protrusion part in which the level rises suddenly in a time direction is detected as an echo signal by a detection part 7. Consequently, a reberveration level in which a change due to a frequency is large is lowered, and an echo signal in which the change due to the frequency is small is emphasized so as to be detected easily.
