Title: Parallel error correction system with interleaving function added
Inventor: HONDA SHUNJI
IPC: H03M13/27
Filed: 1990-02-20
Abstract: PURPOSE:To improve the random processing effect and the error rate characteristic by combining the interleave system with the parallel error correction system. CONSTITUTION:Convolution coders 121-12n of n-set and Viterbi decoders 261-26n of n-set are connected in parallel to form a parallel coding means and a parallel decoding means respectively, thereby obtaining the random processing effect equal to the nXn-bit interleave processing. Moreover, an interleaver 15 and a de-interleaver 21 dispersing consecutive errors at an N-bit interval different from a parallel number (n) are provided between the coders and decoders to disperse the dispersed error. That is, the signal randomized by the interleave system at a receiver side is decoded respectively independently by the parallel error correction system having the randomizing effect. Thus, the randomizing effect is enhanced and the error rate characteristic is improved.

Title: Constant current source type filter having self-bias function
Inventor: NARITA KENJI
IPC: H04M19/00
Filed: 1981-03-19
Abstract: PURPOSE:To obtain a miniature power supply filter having a reduced amount of power consumption and with high impedance, by detecting the DC bias voltage at both ends of a constant current source circuit to which the output current can be set to compare the bias voltage with the reference voltage and then setting the DC bias voltage equal to the reference voltage by the differential component obtained from the above-mentioned comparison. CONSTITUTION:A constant current source type filter 10 is connected between a signal detecting circuit 3 and a DC/DC converter 9 which are connected in parallel to a telephone 1. Then the bias voltage VB of a transistor TRT for control of current is detected by a buffer amplifier 5. At the same time, the reference voltage VC with which the voltage VB is decided is set by a variable resistor VR, and the difference between the voltage VC and the detection output of the amplifier 5 is integrated. Then the output voltage Vref of a low pass filter 7 is produced to satisfy VB=VC. The voltage Vref is supplied to a comparator 8, and the TRT is controlled by the output of the comparator 8 to ensure an equal voltage drop ER between the voltage Vref and the resistance R'. Thus the voltage VB of the filter 10 is held at a constant level.

     CONSTITUTION: Stock sludge containing a great deal of floc is introduced into first tank 1. After the tank 1 is selaed, a valve 12 is opened to feed compressed air to the air to the tank 1. The compressed air is partially dissolved in the stock sludge. Then, a valve 14 is opened to introduce the interior of the tank to atmospheric pressure to thereby generate fine bubbles of dissolved air. The bubbles are adhered to the floc to float it to condense it. A valve 5 is opened to gradually introduce the sludge to second tank 3 at this time. When the liquid level in the tank 1 is lowred to reach a floc layer, the valve 5 is closed and the valve 7 is opned to separate the floc. The method of generatng fine air bubbles in the stock sludge as above may employ the steps of electrolytically decomposing water at energized electrode or reducing the pressure of the stock sludge, or utilizing the pressure difference due to the difference of heights between tanks 1 and 3.
