摘要:
An energy-saving freshwater producing apparatus having a simple apparatus configuration. Seawater is heated by a heat-collecting device based on solar light, and the heated seawater is injected to one or more mist-forming structure formed as a rotor comprising a plurality of collision members formed to extend radially, to form a mist. Water vapor generated from the formed mist is introduced to a heat exchanger arranged in a side-by-side relation to the mist-forming structure in a horizontal direction through a demister, while being carried on an airstream by an airstream-forming device. Low-temperature seawater flows through the heat exchanger vertically from a lower side to an upper side thereof. The introduced water vapor is condensed into freshwater by cold energy of the seawater, and the freshwater is collected.

An audio reproduction characteristic control device reproduces various sound fields by producing reflected sounds of a reproduced source signal. Frequency response characteristic correction parameters for correcting a frequency response characteristic which varies with a reproduction environment to a standard characteristic or other predetermined characteristic is prestored in a memory and one of these parameters is read out in accordance with a designated reproduction environment and, if necessary, additionally with a designated sound field whereby the frequency response characteristic is corrected. In another aspect of the invention, reflected sound signals for front left, front right, rear left and rear right positions of a designated sound field are generated by operating input source signals with reflected sound characteristic parameters and these reflected sound signals are added to the source signals to be propagated from four directions in a space inside of an automobile. An impression of presence in the automobile thereby is improved.
