Abstract: PURPOSE: A method for improving voice signal quality is provided so that a voice spectrum can be improved by estimating a noise spectrum in voice existence/absence sections, and renewing an SNR and gain. CONSTITUTION: An input voice signal is divided in frame units, and the divided signals are converted into frequency region signals. A signal to noise rate(SNR) of a current frame and an SNR of a previous frame are calculated(204). A voice absence probability is calculated from the SNR of the current frame and a presumed SNR of the current frame based on the previous frame(206). The two calculated SNRs are corrected according to the calculated voice absence probability(207). A gain of the current frame decided by the corrected SNRs is calculated, and the resultant gain is multiplied by a voice signal spectrum of the current frame(208). The calculated frame is converted into a time region signal, to improve voice(210). Thereafter, a presumed SNR is obtained by estimating noise and voice power of succeeding voice. The resultant value is output as the presumed SNR. According to the voice absence probability, the noise spectrum is estimated in the voice existence/absence sections, and the SNR and gain are renewed.

Abstract: PURPOSE: A valve for adjusting amount of oil in an oil pump is provided to prevent generation of needless oil amount through bypassing oil according to increase in RPM(Revolutions Per Minute) of an engine. CONSTITUTION: By rotating an engine, a drive gear(46) is rotated to suck oil through an intake port(32). In case of over supply of oil through a discharge port(26), oil is supplied to a chamber(C) through a second orifice(42) of an oil amount adjusting valve(30). Therefore, hydraulic pressure is generated to lower the oil amount adjusting valve. Thus, the valve is lowered while overcoming elastic force of an elastic member(28) to open a bypass conduit(34). A portion of the oil is returned through the bypass conduit, and the other portion of the oil passes through a first orifice(38) for being supplied to a valve body through the discharge port. Therefore, supply amount of oil through the discharge port is limited not to deteriorate efficiency.

Abstract: A decelerator device obtains constant and maximal decelerating power includes by controlling the gas pressure upstream of the valve by balancing the efforts at the pressure-relief valve. The decelerator device (1) includes a balancing device (20) incorporated in the gate (2) body (4) and has a leakage conduit (21) controlled by a calibrated check valve (22). When the valve (7) is closed and, based on a counter-pressure threshold predetermined by the calibration of the compression spring (27) provided at the check valve (22) rear, the latter is lifted from its seat (25) and communicates the channel (5) upstream of the valve (7) with the leakage duct (21) generating an exhaust gas leakage. Beyond the threshold, the calibrated check valve (22) remains open, thereby ensuring constant and maximal counter-pressure whatever the engine speed. The invention is applicable to combustion engine vehicles and in particular industrial vehicles.
