Title: Noise suppressing device
Inventor: MASUDA IKUYO
IPC: G10L25/90
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a noise suppressing device that can suppress noise by predicting the property of a signal from a preceding part of extracted signals even if the property of noise is unknown. SOLUTION: An input voice signal inputted from an input part 1 is intensified in high frequency by a preprocessing part 2, and amplitude spectrum is detected by a spectrum detecting part 3 and stored as measured spectrum in a first storage part 4. Spectral envelope at a following time point is predicted from the measured spectrum by a spectrum predicting part 5 on the basis of the time change locus of spectral envelope. The predicted spectrum and the measured spectrum are compared in a spectrum comparing part 6, and a signal not included in the predicted spectrum is extracted. The spectrum is determined by a spectrum determining part 7, and after being stored in a second storage part 8, the spectrum is Fourier-transformed by an output part 9 so as to be converted into a sound signal and outputted.

Filed: 1988-03-24
Abstract: PURPOSE:To add a delay fitter close to actual network state by reading a data from a storage means in the order of write to the storage means when a significant signal is outputted from a resister stage selected by a selection means after a prescribed time delay. CONSTITUTION:An inputted packet is written from one port 11 of a storage means 1 and stored tentatively and a prescribed time delay is specified to a write timing to the storage means 1 and the shift register means 6 starts the shift operation in the same write timing. After a prescribed time delay specified by the delay generating means 5 elapses, when a significant signal is outputted from a resister stage selected by a selection means 9, the data from the storage means 1 is read from the other port in the order of write and it is sent as a packet. Thus, both delayed and advanced jitters are added to the transmission packet and the evaluation test in response to the actual state is implemented by a packet test equipment.

Filed: 1990-03-19
Abstract: PURPOSE:To simplify the circuitry by employing a single rotation detecting means and employing the output from an existing pole sensor in the judgement of rotational direction in addition to original purpose. CONSTITUTION:An optical sensor 23 produces a pulse signal, for every rotation of the rotor of a reel motor 4b, which is outputted as a rotational position reference signal and a single revolution pulse. A pole sensor signal decoder 32 generates a 3 bit signal (sequence number) based on the logical values of the rotational position detection signals of rotor phi1-phi3 fed from pole sensors P1-P3 and the 3 bit signal is fed to registers 34, 35. The register 34 holds the current phase sequence (sequence number) and the register 35 holds a previous phase sequence based on a register set signal SP provided from a register control pulse generating circuit 33. A comparator 36 compares the sequences in the registers 34, 35 thus judging the rotational direction. Consequently, the pole sensors P1-P3 can be used in detection of the rotational direction as well as detection of rotational position.

Filed: 1990-03-19
Abstract: PURPOSE:To eliminate noise and abrasion caused by the friction between a ratchet claw and tooth by providing a wind-up means possessing a specific wind-up reel, a ratchet wheel, a ratchet arm and a wind-up lever. CONSTITUTION:When a ratchet arm 6 is moved in the opposite direction to the wind-up direction of a cover tape 14a so as to drive a ratchet wheel 3, a ratchet claw 7 at the leading edge of the ratchet arm 6 is pressed by the projecting part 5c of a wind-up lever 5 and the ratchet claw 7 moves under the condition that it is separated from the tooth 3a of the ratchet wheel. Thus, the ratchet claw 7 does not rub the tooth 3a of the ratchet wheel 3 and noise and the abrasion of the ratchet claw 7 and the tooth 3a are eliminated. On the other hand, when driving the wind-up lever 5 in a wind-up direction, the projecting part 5a separates from the ratchet claw 7 and the ratchet claw 7 meshes with the tooth 3a. Then, the ratchet wheel 3 is rotated and driven in the wind-up direction and the cover tape 14 is wound-up. Thus, the abrasion of the ratchet claw and the tooth of the ratchet wheel and the noise are eliminated.
