Abstract: PURPOSE:To enable not only the removal of an org. component but also the removal of chromaticity not inferior to that at a time of the use of activated carbon by adding coffee extract grounds preliminarily subjected to drying treatment, carbonizing treatment or chemical treatment to an aeration tank when waste water is subjected to activated sludge treatment. CONSTITUTION:Coffee extract grounds are dried for 3hr or more, for example, at 110 deg.C or lower by hot air drying or air drying or carbonized, for example, at 900 deg.C or lower for 10hr or less. In chemical treatment, an alkali agent or an oxidizing agent is used. By applying these treatments, the color component removing capacity as powdery activated carbon is obtained and the sedimentation properties in a final sedimentation basin are excellent and the quality of treated water is stable. Further, waste water is inexpensively treated without damaging sewage dehydrating properties.

Abstract: PURPOSE: To generate electricity in an economical manner from general view point by the use of a relatively small scaled power plant, by driving a generator by the use of small particles of steel or lead instead of water.  
     CONSTITUTION: When a gate 3 disposed at the bottom of steel or lead particle reserving tank 1 that corresponds to a reservoir in a hydroelectric power plant is opened, small particles 2 of steel or lead in the tank 1 fall through a pipe 4 or the like at a high speed and are ejected from a nozzle 5 onto buckets 7 of a runner 6 at an increased speed. Resultantly, the runner 6 is caused to turn at a high speed together with driving wheels 8, 9, so that a turbine 10 connected to the driving wheels 8, 9 is caused to turn and a generator 11 connected to the turbine 10 is driven in turn. Electricity thus generated is sent to a transformer 12, and after adjustment of voltage at the transformer 12, is transmitted from a power board 13. On the other hand, small particles 2 of steel or lead are collected into a conduit 14 after use for driving the runner 6, and then carried back to the tank 1 by means of a lift 16.

Abstract: PURPOSE:To perform uniform oil coating at a prescribed oil coating amt. by controlling not only the feed rate of the carrier air for spraying oil coating material particles to an oil coating chamber but also the pressure of the atomizing air to be supplied to an atomizer. CONSTITUTION:The atomizing pressure P and carrier air flow rate G corresponding to a transfer speed V are empirically determined so as to obtain the desired oil coating amt. T. The atomizing pressure P and the carrier air flow rate G are expressed by the respective prescribed functions P=f(V), G=h(V) in such a manner that the former increases gradually in the form of a polygonal line from 0 and that the latter increases linearly up to 30-80%. Such pressure and flow rate are preliminarily stored into a memory device 23. The atomization starts from 0 pressure of a pressure adjusting valve 26 and 30% carrier air flow rate at the transfer speed V=0 of the material 3 to be coated when a control device 20 is turned on. The atomizing pressure P and the carrier air flow rate G are calculated and the valve 26 is controlled on a gradual increase of the transfer speed V. A uniform amt. of the oil coating material is thus maintained.

Filed: 1980-09-08
Abstract: PURPOSE:To obtain a muting circuit which can suppress pop sound to a small value in high speed, by providing a switching means which makes short-circuit the both ends of a resistive element having proportional relation with the gain of an amplifier. CONSTITUTION:A muting circuit 6 consisting of transistors (TR) Q5-Q9 is provided for a PWM amplifier 3 consisting of TRs Q1-Q4 amplifying the output signal of a PWM modulator 2. If no muting signal to the TRQ5 is present, the TRs Q5-Q9 turn off and the amplifier 3 makes normal amplification. When the muting signal to the TRQ5 is at high level, the TRs Q5-Q9 are turned on, and collector resistors R3, R4 proportional to the gain of the TRs Q1, Q2 of the amplifying circuit are in short circuit with the TRs Q8, Q9. Thus, the circuit gain is controlled to zero and no signal is introduced to the output for muting operation. High speed operation is possible to constitute the muting circuit electronically, and since muting is given with the PWM amplification circuit, no pop sound is amplified in comparison with the muting at the first stage of the system, allowing to suppress the pop sound.
