Title: Howling suppressing device
Inventor: FUJIMOTO YUKIHIRO
IPC: H04R3/02
Filed: 1986-06-24
Abstract: PURPOSE:To obtain a stable suppressing circuit by forming a delay circuit where a power is calculated in accordance with the output of a microphone and an impulse response is estimated at each time of break of voice to obtain only the feedback signal from a speaker in the microphone. CONSTITUTION:The delay circuit is so formed that the speaker output can be obtained even if the voice of a speaker is broken. The power is always calculated in accordance with the output signal of a microhone 1 to detect a break of voice at the time when the power is reduced to a half or lower, and the start timing of impulse response estimation is given to a response estimating circuit 5. The response estimating circuit 5 estimates the impulse response between the speaker 2 and the microphone 1 by the learning identification method in accordance with outputs of the microphone 1 and a delay circuit 4 and falsely generates the feedback signal from the speaker 2 to the microphone 1 by the convolutional operation of the impulse response and the output of the delay circuit 4 and subtracts this signal from the output of the microphone 1. Thus, howling is stably suppressed.

Filed: 1977-12-05
Abstract: PURPOSE:To prevent the effect caused by mixture of the current switch type logic circuit and the logic circuit of other type by forming the constant current source  circuit which varies the constant current value in accordance with the variation of  the positive side voltage. CONSTITUTION:Resistance RC is connected to the collector of transistor TR at the input side and the reference voltage side, with voltage VCC at the positive side electrode and constant current IS. And reference voltage VS with which voltage VCC and voltage VO of the reference point featuring the relatively stable potential lower than VCC plus VCC are supplied to the base of TRQ3 via diode DD1, D2, resistance R1, diode DD3 and resistance R2 respectively. Here, fluctuation DELTAVOL of low-level output VOL is shown by the equation against fluctuation DELTAVCC of voltage VCC. When this value is zero, VOL is not affected by the fluctuation of VCC. In other words, output voltage VOL which is not affected by VCC can be obtained by turning the result of the equation to zero through selection of resistance R1, R2, RE and RC respectively.

Title: Device with crystal oscillator
Inventor: ISHIHARA HIROKATSU
IPC: H04B1/04
Filed: 1993-06-17
Abstract: PURPOSE:To miniaturize a DC power supply circuit by suppressing the maximum output power source capacity of the mounted DC power supply circuit at an irreducible minimum for real operations. CONSTITUTION:Since a contact 11a is opened when the supply of DC power from a DC power supply circuit 1 is started, DC power 1 is supplied through a current monitor circuit 9 to a crystal oscillator 2 and supplied only to a relay driving circuit 11. When the current monitor circuit 9 detects that a current which is maximum at the beginning and supplied from the DC power source 1 to the crystal oscillator 2 is lowered to a prescribed value, the contact 11a is closed by operating the relay driving circuit 11. Therefore, DC power is supplied to an amplifier 4 and an amplifier 6 as well, and a circuit starts an operation to convert an intermediate frequency signal to an RF frequency signal in a normal state. Thus, the maximum supplied current value supplied from the DC power supply circuit 1 just after a power source is turned on can be suppressed, and the power source capacity of the DC power supply circuit 1 can be reduced just for the suppressed value.

Filed: 1988-06-14
Abstract: PURPOSE:To operate the circuit at both high and low gain states by providing a high gain charge pump circuit employing a C-MOS analog switch and a low gain charge pump circuit employing a current switch circuit and switching the two charge pump circuits. CONSTITUTION:The high gain charge pump circuit 16H employs a C-MOS analog switch. Thus, in the high gain mode, the switching speed is high and the leakage current is small, then the output is very stable in the absence of the input. Moreover, the low gain charge pump circuit 16L uses a current switch comprising transistors TR1-TR4 and an NPN bipolar TR. Since the NPN TR has a large current driving force and the collector-base capacitance is small, the TR is controlled with high accuracy by a minute signal at a high frequency. Thus, the phase locking is obtained in an excellent way at both the high and low gain sides.

Filed: 1985-07-05
Abstract: Speech detection is accomplished in conjunction with two-band subband encoding. A detection statistic T (i tau 0), used to estimate the short-term speech energy, is developed from energy estimates made in each subband. A speech presence energy threshold  lambda ON a speech silence energy threshold  lambda OFF and  lambda OFF are computed which adapt to the long-term speech level. The detection statistic is compared to the thresholds to make a decision concerning the presence or absence of speech. Also disclosed are considerations for extrapolating the detection to result in an arrangement with more than two subbands.
