Title: Echo canceller circuit
Inventor: TAMAKI NORIO
IPC: H04B3/23
Filed: 1987-07-10
Abstract: PURPOSE:To obtain stable and high echo suppressing effect by constituting the titled circuit by an IIR digital filter and an adaptive FIR digital filter. CONSTITUTION:The echo detoured from the sender side to the receiver side is cancelled by the IIR digital filter 10 and the adaptive FIR digital filter 11. In the IIR digital filter 10, the characteristic cancelling the detouring echo connecting some kinds of subscriber lines in advance is stored in the coefficient memory. That is, e.g., a training pattern or the like is sent to an optional subscriber line to select the coefficient memory of the IIR digital filter 10 to minimize the deviation and the adaptive FIR digital filter II cancels the deviation. Thus, the echo suppressing effect is increased and the stable operation is attained.

Title: Methane fermenting vat
Inventor: MASAMOTO KIYOUJI
IPC: C02F11/04
Filed: 1980-12-06
Abstract: PURPOSE: To effectively crush scum and to raise efficiency, by dividing the main body of a vat into an upper chamber and a lower chamber, bending the lower parts of a transfer pipe provided with an opening including a nonreturn valve and a crude material-charge pipe into a U-shape, and opening these pipes near the top of the lower chamber.  
     CONSTITUTION: A crude material, to be fermented, charged into a crude material-charge pipe 7 falls downwards inside the pipe 7 through its U-shaped bottom and its opening part 7a to the interior of a lower chamber 4, and crushes scum on the surface of fermented liquid 11. The reserved fermented liquid 11 generates methane gas which is accumulated at the upper part of the lower chamber 4 to push away a proper amount of the fermented liquid. The pushes liquid 11 reaches the interior of an upper chamber 3 through a transfer pipe 8. Thereafter, the methane gas accumulated at the upper part of the lower chamber 4 is taken out through an extraction pipe 5, so that the gaseous pressure is lowered and that the fermented liquid 11 flows through the transfer pipe 8 and falls onto the surface of the fermented liquid 11 in the lower chamber 4 from the opening part 8a of the pipe 8. Consequently, due to the impact of the falling liquid 11, the scum on the surface of the liquid 11 is crushed and the liquid 11 is agitated.
