Title: Noise reduction device
Inventor: MIHASHI YASUO
IPC: H04N5/21
Filed: 1988-02-03
Abstract: PURPOSE:To reproduce the picture of good quality without making a noise at the outline part of the picture prominent by using a vertical correlation when the noise component has the vertical correlation and correcting the noise component with a BPF and a limiter circuit having non-linear characteristics and subtracting the corrected noise component from its original signal when the noise component has no correlation. CONSTITUTION:A video signal (b) is subtracted from an original video signal (a), which is delayed for 1H at a 1H delaying circuit 12, and from which its clock frequency of 3.58MHzX4 and its high frequency component are eliminated, at a subtracting circuit 14. Since the noise component has no correlation, it is outputted as a random noise signal (c) and inputted to an equalizer circuit 15, near about 3.58MHz in the random noise signal (c) is emphasized, and after that, the emphasized random noise signal (c) is inputted through a BPF16 and a limiter circuit 17 having the non-linear characteristics to a phase correcting circuit 18 and phase-corrected. Next, the phase-corrected emphasized random noise signal (c) is passed through a buffer amplifier 19 and an inversion amplifier 20, and the corrected noise signal is subtracted from the original video signal at a mixing circuit 21. Thus, an S/N can be improved, and the picture of the good quality can be obtained without damaging the resolution of the high frequency component.

Title: Am detection circuit
Inventor: OKASHIN YAMATO
IPC: H03D1/18
Filed: 1979-03-02
Abstract: PURPOSE: To secure the detection with no distortion although the signal level is small, by performing the detection with the 100% negative feedback applied to the SEPP amplifier.  
     CONSTITUTION: The AM signal source such as intermediate-frequency amplifier 1 consists of transistors TRQ 1 ∼Q 6  and is connected to SEPP amplifier 2 to which the 100% negative feedback is applied. In such way, the positive half cycle of the intermediate-frequency signal turns to the collector current of TRQ 5 , and the negative half cycle becomes the collector current of TRQ 6  each. Here TRQ 7  and TRQ 8  are connected under the same conditions as TRQ 5  and TRQ 6  respectively, and thus the collector current is equal between TRQ 5  and TRQ 7  as well as between TRQ 6  and TRQ 8  respectively. Accordingly, the detection voltage is obtained at resistance R 11  with every positive and negative half cycles to be extracted via LPF 3 . In such way, the detection becomes possible without any distortion even with the small signal level.

Abstract: PURPOSE:To systematically handle video, sounds, and data by using a mechanism of digital VTR having a mobile element for displacement of the trace position and using the same head as video recording to reproduce and confirm computer data at the time of recording of this data and displacing the trace position to use it for reproducing. CONSTITUTION:Heads 11A and 11B are used for recording as well as reproducing and have opposite azimuths. When this device is used for a digital VTR, heads 11A and 11B are switched at intervals of a half rotation of heads by a switch 12 and a recording signal is alternately given to them, and heads are alternately used to detect a reproduced signal at the time of reproducing. When this device is used for a recorder, the tape speed is reduced to a half, and both heads reproduce data recorded in the preceding rotation after recording data, and a track pattern is alternately recorded by two heads. Each head is attached to a piezoelectric element 14, and the element 14 determines the trace position of each head by the voltage of a controller 13. Since the tape speed is a half of that for video recording and reproducing, the recording density is not reduced. By this constitution, the device is used for the digital VTR as well as the data recorder.

Filed: 1981-02-25
Abstract: PURPOSE:To eliminate a mixed noise from a noise source efficiently by clamping the characteristics of a variable delay device and a phase inverting and varying amplifier when a sound is sent from a sound noise. CONSTITUTION:A noise collected by a microphone 13 is inputted to an adder 17 through a variable delay device 15 and a phase inverting and varying amplifier 16. A sound sent from a sound source 12 and the noise from a noise source 11 are collected by a microphone 14 and inputted to the adder 17.
