Title: Process and apparatus for treating sewage
Inventor: MIHASHI KAORU
IPC: C02F3/12
Filed: 1988-04-25
Abstract: PURPOSE:To obtain a clear discharged water in a filthy water treating apparatus by eliminating insufficiency in total aeration degree by increasing an extent of succeeding intermittent aeration, or by retarding excessive proliferation of microorganisms which proliferate under a relatively anaerobic condition by giving an implus of strong aerobic condition. CONSTITUTION:For example, a treating time of intermittent aeration is set at 6hr with a timer T1, and a settling time is set at 1hr with a timer T2. Further, a discharging time is set at 2hr with a discharging time judging timer T3. When the discharging time exceeds 2hr, a ratio of an aeration time to nonaeration time of a normal operation is changed from 1:1 to 2:1 (for a second intermittent aeration line). Thus, an extent of total aeration is kept in an appropriate range by increasing an extent of succeeding aeration when a degree of aeration is insufficient, or a strong impuls of aerobic condition is given to microorganisms group which propagate under anaerobic condition by increasing an extent of aeration remarkably temporarily. Thus, bulking phenomenon is prevented, and discharged water of good quality is obtd.

Title: Cement waste water neutralizing method applying fluid element type mixing agitator
Inventor: KAWASAKI KENJI
IPC: C02F1/68
Filed: 1979-08-14
Abstract: PURPOSE: To neutralize cement waste water with high efficiency by supplying CO 2  gas from the inner nozzle of a double-tube type mixing agitator to the water supplied from the outer nozzle to cause oscillation swirling flows.  
     CONSTITUTION: When cement waste water is fed under pressure from outer nozzle 3 of the double-tube type fluid element mixing agitator, and CO 2  gas is supplied from inner nozzle 2, the mixture causes swirling flows in oscillator 1. The flows perform powerful agitation while presenting the phenomenon of reversing the swirling direction (oscillation phenomenon). At the time of this mixing agitation, the CO 2  gas is converted into fine bubbles to increase the reaction contact interface between the gas and the waste water, so high-speed vapor-liq. mixing is carried out to neutralize the water with CO 2  gas in an amount close to the theoretical value. The neutralized water is discharged from discharge pipe 4.

Abstract: PURPOSE:To lower the electric power for driving and to reduce the size over the entire part of the device by driving a piezo-electric oscillator by the tone burst signal which intermits the alternating voltage signal essentially consisting of the basic resonance frequency of the piezo-electric oscillator at specified time intervals. CONSTITUTION:A signal S1 is outputted from the final stage of a square wave oscillation circuit 10 and a frequency dividing circuit 11 and the signal S2 having the frequency of twofold the frequency of the signal S1 and the signal S3 corresponding to the basic resonance frequency of the piezo-electric oscillator 1 are outputted during the course of such output. An amplifier circuit 13 for which an operational amplifier is used and which has a low band pass characteristic amplifies the output signal of a NAND gate 12 and executes the low band pass. The resonation of the piezo-electric oscillator 1 only to the basic resonance frequency is enabled by setting the cut off frequency of the amplifier circuit 11 in such a manner that the higher order and higher harmonic wave components of the piezo-electric oscillator 1 can be cut. The body to be oscillated is thus oscillated at specified time intervals so that said oscillations are easily sensed.

Title: Plasma processing method and device therefor
Inventor: YUKIMASA TORU
IPC: H01L21/3065
Filed: 1985-05-17
Abstract: PURPOSE:To prevent a sample from damaging by converting a microwave having high energy value into a light having slightly smaller energy value, emitting it to a processing gas, thereby generating a plasma having small energy value. CONSTITUTION:A microwave oscillated by a microwave oscillator 5 is guided through a waveguide 6 to a sub chamber 1, emitted to the processing gas filled in the chamber 1 to convert the gas into plasma, thereby emitting a light. This light passes a quartz 3 to collide with the gas in a processing chamber 2 to convert the gas into a plasma. The plasma generated in the chamber 2 has lower energy than that generated in the chamber 1. The plasma generated in the chamber 2 thereby processes a sample 15. Thus, it can prevent the sample 15 from damaging.
