The steam generated passes through demister 8 to separate water, flows into horizontal heat transfer tubes 5 of the effect of lower stage evaporation unit Q, and acts as heating steam for the effect. On the other hand, unevaporated brine in effect evaporation chamber 1 of unit P is introduced into flash box 9A of first stage flash evaporation chamber 6A through the lowr part of partition wall 7 to flash evaporate the brine. The steam generated is passed through demister 10A to separate water, heat exchanged for supplied water in feed water preheater 2A, and condensed to fresh water, which flows into fresh water tray 12A.

Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To facilitate the regulation of a humidity by rotating a fan when a compressor is stopped, and sending an air flow to a humidifying partition chamber except a specific partition chamber. SOLUTION: In a refrigerating mode, a refrigerant does not flow to an evaporator (R evaporator) 34 for a cold storage chamber, and no cold air flows to the storage chamber 14 and a vegetable chamber 16. But, since these chambers are in dry states of cold air, it is suitable to supply the air containing a moisture for preserving food. Thus, in the refrigerating mode, a fan (R fan) 36 for the storage chamber is rotated to melt a frost adhered to the evaporator 34 by its air flow to supply the air containing the moisture to the chambers 14, 16 to humidify in the refrigerator. When a switching chamber 19 is set to a cold storage chamber temperature, a vegetable chamber temperature or a wine temperature, it is suitable to send the moisture containing air similarly to the chamber 14.  Then, a humidifying damper 78 is closed, the moisture containing air is sent to the chamber 19 via a duct 74 to humidify food preserved in the chamber. Thus, a humidifying partition chamber can be humidified therein and its humidity can be regulated.

IPC: G11B7/00
Filed: 1987-03-18
Abstract: PURPOSE:To form pits, which the unnecessary pulse width variation of a signal reproduced from is small, on a recording medium by providing a means which keeps the detection level constant. CONSTITUTION:The time t1 indicating the pulse width of a waveform G is longer and the analog output of a D/A converter 34 is increased according as the inclination of a slope part 18 of a waveform B is gentler, but the analog output is reduced when the inclination of the slope part 18 is rapider. This analog output and the output of a third reference power source 36 are compared with each other by a differential amplifier 35, and the feedback control of the output signal intensity of a recording signal source 9 is preformed. A laser light source 1 is so controlled that the analog output of the D/A converter 34 is always equal to a reference voltage VC of the reference power source 36, and the inclination of the slope part 18 is controlled to be always kept constant. Thus, the unnecessary width variation of a reproduced waveform J obtained by reproducing pits is prevented.
