Title: Ultrasonic range finder
Inventor: KATAYAMA SUSUMU
IPC: G01S15/08
Filed: 1987-06-15
Abstract: PURPOSE:To improve the ability for detecting a near object by providing plural- level detecting circuits having respective different thresholds of waveform shaping means. CONSTITUTION:The output of a wave receiving circuit 4 is compared with respective thresholds Va-Vd by the use of a level detecting circuit 5, and the waveform exceeding a threshold is shaped into a high level digital signal. The output of the level detecting circuit 5 is differentiated in a differentiating circuit 6 into resultant output. A negative pulse indicating the fall of the output of the level detecting circuit 5 is removed by depriving the logical sum of the output of the differentiating circuit 6 by the use of an OR circuit 7, and the output is obtained on the basis of only a positive pulse indicating the rise of the level detecting circuit 5. When the last output of an OR circuit 12 is input in a latch circuit 12, the distance of count value up to an object is computed. In this case the distance of a near object can also be detected unless the output is completely covered by a reverberating signal, and the ability for detecting the near object is improved.

Title: Sea water desalting apparatus utilizing lng cold latent heat
Inventor: EBARA KATSUYA
IPC: C02F1/22
Filed: 1979-11-19
Abstract: PURPOSE: To prevent freezing faults and obtain good heat transfer performance by perpendicularly installing heat transfer pipes of a desalting apparatus utilizing LNG cold latent head and maintaining a refrigerant liquid film at uniform thickness on the heat transfer pipe surface.  
     CONSTITUTION: Sea water is admitted into a crystallizing vessel 52 by using a sea water pump 62. On the other hand, the refrigerant liquefied through cooling and condensation by LNG cold latent heat with an LNG evaporator 51 is admitted therein by a refrigerant pump 60 and is directly contacted with the raw sea water. The sea water is cooled and produces cryohydrate 64. In addition, the refrigerant evaproates to gas which is then exhausted from a pipe 56 and enters the LNG evaporator 51 through a refrigerant gas inlet 57. Since heat transfer pipe parts 54 which perform heat exchanging of LNG and refrigerant gas are installed perpendicularly, the refrigerant flows down by constantly forming thin films under the heat transfer pipes. Hence, the phenomenon of decreasing heat exchange efficiency by freezing of the water content entrained in the refrigerant gas on the heat transfer pipes may be prevented.
