Title: Control apparatus for sludge treatment system
Inventor: INOUE AKIRA
IPC: C02F11/12
Filed: 1987-07-13
Abstract: PURPOSE:To reduce the frequency of pump starting and stopping by providing the captioned system with a level meter for measuring sludge levels and a target flow quantity calculation portion for the target sludge level. CONSTITUTION:Corrections for the predetermined sludge flow quantity target value Qr are made using the sludge level Li in a sludge entrance tank 3 and the sludge level L0 in a sludge exit tank 4. The corrections are made, so that the higher the sludge level Li becomes than the predetermined upper level, the greater the target value is and the lower the sludge level Li becomes than the predetermined lower level, the smaller the target value is. As for the sludge level L0, the corrections are made within the range from upper limit to lower limit level, so that the higher the sludge level becomes than the predetermined upper level, the smaller the sludge flow quantity target value is and the lower the sludge level becomes than the predetermined lower level, the greater the target value is. This permits a continuous treatment operation, improving the sludge treating efficiency.

Filed: 1983-09-19
Abstract: PURPOSE:To obtain a ciphered sound signal having nearly the same band width as that of sound by applying SSB modulation to a carrier synchronized with a video signal with the sound signal in a video sound simultaneous transmission system. CONSTITUTION:A carrier oscillator 2 generates a carrier in synchronizing with a video signal inputted to an input terminal 1 and an SSB modulator 4 applies SSB modulation to the said carrier with a sound signal inputted to an input terminal 3. An FM modulator 5 modulates sound subcarrier with the ciphered sound signal and a branching filter 6 synthesizes the video signal and the sound subcarrier and outputs the result to a terminal 7. The video signal and the sound subcarrier inputted to an input terminal 8 are separated at a branching filter 9 and the sound subcarrier is demodulated by an FM demodulator 10. A carrier generator 11 outputs a carrier for sound demodulation synchronized with the video signal and the SSB demodulator demodulates the ciphered sound signal and outputs the signal to a terminal 14.
