Title: Noise reduction circuit
Inventor: IKEDA YUKIHISA
IPC: G11B20/02
Filed: 1990-03-23
Abstract: PURPOSE:To reduce a noise component included in a sound signal by suppressing the reduction of the reproducing sound signal at the time of reproducing by emphasizing the reduction of the sound signal at the time of recording when the detected levels of a high range component and a low range component in the sound signal are lower than prescribed values. CONSTITUTION:A level detecting means 12 respectively detects the levels of the high range and low range components in the sound signal. When the level of the high range component is high and the level of the low range component is sufficiently low, a high-pass filter 11 changes the amount of attenuating the reduction of the reproducing sound signal based on the detected results of the level detecting means 12, executes low range emphasis at the time of recording and executes low range suppression at the time of reproducing. Thus, the noise in the low range of the sound signal to be reproduced can be reduced.

Filed: 1992-03-30
Abstract: PURPOSE:To simultaneously use the device in different modes by dividing an input video signal into plural channels so that the picture elements of the same channel can not be arranged vertically and horizontally, and utilizing an existent error correcting circuit when there is any error at one part of a picture in the case of reproducing this video signal after it is recorded onto a tape. CONSTITUTION:The difference of this device from the conventional digital VTR is that still control signals 41a and 41b are respectively inputted from a mode setting circuit 27 to the reproducing device for each channel A or B and that error correcting flags 25a and 25b outputted from reproducing processing circuits 21a and 21b are temporarily inputted to OR circuits 26a and 26b and afterwards supplied to a channel merge circuit 22 after those flags are respectively ANDed with forced correcting signals 43a and 43b from the circuit 27. Thus, the special functions such as independent recording and reproducing display to the two systems of sources and the switching display of still pictures in the past and regenerative images at present are realized. Namely, the signals of the first source are recorded in both of channels A and B and afterwards, those signals are reloaded with the other source signal only in the channel B.

Abstract: PURPOSE:To form a wiring part and an electrode by using polysilane for a conductive layer, by applying ultraviolet ray through a patterning mask and by forming an insulating layer of a part whereto ultraviolet ray is applied. CONSTITUTION:Polysilane such as methylphenylpolysilane is applied uniformly to an insulating layer 12 formed on a surface of a substrate 11.
