Title: Method and device for mixing surround signal
Inventor: AYLWARD RICHARD J
IPC: H04S3/02
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To realize an enhanced device and technology to process a surround signal. SOLUTION: A down-mixing device includes an adder that adds original left/right channel surround signals to a single monaural sound pair and a level detector that provides an absolute value signal denoting the absolute value of the magnitude of the original left/right channel surround signals that are averaged temporally. Then a sum signal of monaural sound signals is filtered and 1st and 2nd time varying coefficient signals (A1 and A2) are respectively multiplied by the filtered signal. A subtractor subtracts time varying product signals (HsA1 and HsA2) from the sum signal of the monaural sound signals that are not filtered to produce two encodable signals 1-HsA1 and 1-HsA2. Then the two encodable signals are typically synthesized with at least one of a front center signal and left/right signals to obtain stereo sound pairs consisting of left/right transmission signals LT and RT.

Filed: 1981-12-26
Abstract: PURPOSE:To reproduce an audio signal having high quality, no impulsive noise and excellent fidelity by demodulating FM-modulated reproduction outputs obtained from two reproducing rotary magnetic heads alternately into reproduced audio signals to concatenat the signals. CONSTITUTION:Reproducing magnetic heads 31 and 32 scan on slanting adjacent tracks t1 and t2 of a magnetic tape T alternately accompanied with overlap  time. The head 31 generates the reproduction output of the 1st mixture output  M1, and the head 32 generates the reproduction output of the 2nd mixture output  M2. Those outputs are supplied to a video signal processing part 35 through  amplifiers 33 and 34. At the same time, those outputs are supplied to FM demodulators 44-47 through band-pass filters 36-39 and amplitude limiting circuits 40-43, so that a reproduced left signal SL and a right signal SR are  obtained alternately accompanied with a overlapping. The signals are passed  through low-pass filters 48-51 to concatenate within the overlap time by switching circuits 53 and 54. Consequently, no impulsive noise is generated.

Filed: 1991-07-30
Abstract: PURPOSE:To uniformly heat a material with respect to its cross section regardless of the change in the quality and thickness of the material in the device for electrically heating the material through an annular transformer. CONSTITUTION:The frequency to be set by a frequency phase converter 42 is set by a frequency conversion control part 44 in accordance with the quality and thickness of a material to be heated.

Abstract: PURPOSE:To improve the naturalness of conversation and understandability by executing a prescribed operation, presuming the voice/amplitude ratio of a nearby speaker, and controlling an attenvator attenuating quantity based on a presumed value. CONSTITUTION:From the outputs of a reception amplitude calculating part 109 and a transmission amplitude calculating part 110, an exchange amplitude ratio calculating part 111 calculates the ratio between a reception input amplitude value and a transmission input amplitude value.
