Abstract: The invention provides surround mode stereophonic reproducing equipment for using the Dolby surround mode and another surround mode other than the Dolby mode by means of selectively switching between them. The equipment is provided with two front power amplifiers for driving front speakers on the right and left, and two rear power amplifiers for driving the rear speakers. The rear speakers are driven jointly by one of the rear power amplifiers while the center speaker is driven by the other power amplifier when using the Dolby surround mode, and the rear speakers are respectively driven by the two rear power amplifiers when using a surround mode other than the Dolby surround mode.

Abstract: The present invention relates to a thermomagnetic recording apparatus in which a chemical compound material the Curie point of which varies in response to a ratio of chemical combination in chemical compound constituent is utilized as a magnetic material for its magnetic recording medium, and the Curie temperature is set higher than the ambient temperature by a prescribed value on the ratio of chemical combination determined, thereby resulting in printing at a relatively low temperature and precision of printing in a prescribed degree.
