Title: Coding and decoding device
Inventor: TSUNEHIRO TAKASHI
IPC: H03M13/00
Filed: 1986-07-04
Abstract: PURPOSE:To correct an error of a received code at a high speed by switching a generation polynomial used for coding/decoding of a feedback shift register, replacing the content of a flip-flop and applying shift till a zero detection circuit detects all zero. CONSTITUTION:When a syndrome detection circuit 37 detects that an output of all flip-flops are not zero, a feedback shift register of a generation polynomial g(x) is used as a feedback shift register bringing a signal line 47 to a high level and realizing a polynomial obtained definitely as x<l>. g(1/x). Then the content of the flip-flop in the descending order from the most significant flip-flop sequentially is replaced with the content of the flip-flop in the ascending order from the least significant flipflop as to the content of each flip-flop of l-set constituting the feedback shift register. Then a zero detection circuit 38 repeats the shift until all the outputs of (l-m)-set of flip-flops are all zero and outputs the output of the m-set of the flip-flops as an erroneous pattern when the zero is detected.

Title: Fuel injection valve
Inventor: ETOU YUKIHIRO
IPC: F02M45/12
Filed: 1981-10-02
Abstract: PURPOSE:To reduce the vibrations and noises of an engine by a method wherein a passage for relieving a small quantity of fuel at the time of lifting a needle valve to open in a low speed rotation and low load operation zone of the engine including idling is provided through the needle valve and a nozzle head and the injection of fuel during the period in which the ignition of fuel is delayed is controlled. CONSTITUTION:When the engine is operated in a low speed rotation and low load condition including idling, the needle valve 1 is lifted by a predetermined amount due to the pressure of the fuel introduced into a fuel sump 10 and a very small quantity of fuel leakes into a relief port 13 through the fuel relieving passage formed of a passage 24, a vertical groove 21, an annular groove 23 and a passage 25 so that the pressure of the fuel injected from an injection port 16 is lowered and the rate of fuel injection decreases. Consequently, the rotation speed of the engine drops for a moment but a governer senses it and operates to keep the idling or the low speed rotation and low load condition of the engine in such a manner that the period of fuel injection is extended while a small quantity of fuel is kept injected, to thereby prevent the reduction of the quantity of fuel injection.

IPC: H04B3/23
Filed: 1990-06-14
Abstract: PURPOSE:To prevent increase in an estimate error of an echo path and increase in a residual echo attended therewith by multiplying a scaling factor with a filter coefficient so as to control the absolute value of the filter coefficient not in excess of the calculated maximum value and multiplying a reciprocal of the scaling factor with a pseudo echo. CONSTITUTION:A coefficient control circuit 4 is provided to fetch a filter coefficient revised by a coefficient revision circuit 3 thereby deciding a maximum value in the absolute values. Then when the maximum value of the absolute values of filter coefficients exceeds the calculation maximum value, a scaling factor is multiplied with the filter coefficient so as to control the filter coefficient not in excess of the calculated maximum value and a reciprocal of the scaling factor is multiplied with a pseudo echo from a FIR filter at multiplication. Thus, the tap coefficient of the FIR filter 1 does not exceed the calculated maximum value by the hardware and the calculation error due to overload is avoided. Thus, the increase in the estimate error of the echo path is prevented and the increase in the residual echo is suppressed.
