Title: Noise trapping circuit and low noise electric acoustic device using this circuit
Inventor: JIEI EI KARUBAATO
IPC: G01S7/536
Filed: 1988-08-03
Abstract: PURPOSE: To provide an output of a signal without noise from an output terminal by providing a block circuit, a shunt circuit and a feedback circuit between input/output terminal circuits, keeping a large level signal when it is detected in an input signal and suppressing noise when the noise is detected. CONSTITUTION: Diodes D1, D2 are connected between input terminals 22a, 22b and output terminals 24a, 24b to form a high impedance path between input and output terminals for an input noise and a low impedance path for a large level signal. On the other hand, FETs M1, M2 attenuate a noise when they are conductive with a bias voltage by a positive gate 7 source bias power supply 28 so as to form a low impedance branch and do not attenuate the large level signal when they are nonconductive to branch the signal to output terminals 24a, 24b. Then a parallel impedance circuit consisting of a resistor R1 and a capacitor C2 and transistors (TRs) Q1, Q2 form a feedback circuit and when no large signal is in existence in an input signal, they are conductive to keep a FET branch and when the large signal is detected, they are nonconductive to keep the FET branch.

Inventor: MAEKUMA FUJIO
IPC: B65H45/107
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a winding method for a sheet-like article and its device capable of enhancing the productivity by carrying out winding with the fluctuating operation of a sheet-like article adjusted by corresponding to feeding speed for a product and by regularly aligning the folding part. SOLUTION: A sheet-like article-fluctuating mechanism shortens the fluctuating cycle of a sheet-like article SMC as the feeding speed of the supplied sheet- like article increased. A tension roll moving mechanism interlocks with the fluctuating mechanism and provides the optimum tension to the sheet-like article SMC with a tension roll 4 reciprocated at high speed. On the contrary, when the feeding speed of the transferred sheet-like article SMC is reduced, the fluctuating cycle is extended to provide the optimum tension to the sheet-like article SMC with the tension roll 4 reciprocated at slow speed.
