Title: Pressure reducing boiler type vaporizer and control thereof
Inventor: NUKUI KAZUMITSU
IPC: F17C9/02
Filed: 1991-03-05
Abstract: PURPOSE:To provide a pressure reducing boiler type vaporizer stable and good in control responsiveness. CONSTITUTION:A pressure reduced steam generating boiler 11 and a pressure reduced steam boiler 12 are installed in communication with each other and a heating medium pipe 14 for passing steam therethrough is provided in the pressure reduced steam generating boiler 11. A heat transfer pipe 17 for passing LNG into the pressure reduced steam boiler 12 is provided. The water temperature and pressure in the pressure reduced steam generating boiler 11 are detected in comparison with the water temperature-to-pressure corresponding relationship in an ideal condition to monitor deviation and, if any deviation is detected a non-condensable gas can be considered to be mixed in the boiler. In the case of a change in the flow amount of LNG, since the judgement by comparison of the water temperature-pressure relationship in the ideal condition is stopped and since a detection signal switching means 23 is switched to effect feed-back control based on the detection signal from a water temperature sensor 18, there is no possibility of erroneous judgement and this method provides a good control responsiveness as well as stability.

Title: Production of electrode
Inventor: HASHIMOTO ICHIRO
IPC: C25B11/08
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To simplify the process and to decrease the working time by carrying out AC electrolysis in a plating liquid essentially comprising Ir to form a continuous layer of Ir oxide on a base body. SOLUTION: The AC waveform used for the AC electrolysis is preferably a triangular, sine or square waveform or asymmetric waveforms of these. The scanning range of the potential in the electrolysis is preferably controlled from the generation potential of oxygen to the generation potential of hydrogen or the reduction potential of Ir. Namely, when a silver/silver chloride electrode is used as a referential electrode, the potential is preferably controlled to the range from -1.5 V to +2.0 V. After an Ir oxide layer is formed by the AC electrolysis, the produced state of the oxide can be made more complete by a heat treatment. The heat treatment is preferably carried out in the air at 450 to 800 deg.C. As a result, the life of the electrode can be increased.  As for the plating liquid, for example, a liquid essentially comprising an Ir bromide acid salt or the like with addition of oxalic acid or the like can be used.

Filed: 1980-05-16
Abstract: PURPOSE: To obtain an efficient fresh water generator using a cooling heat of generated water, by combining the cooling of a liquid refrigerant and the thawing of frosts in a water-generating portion with water heated by the cooling of the refrigerant.  
     CONSTITUTION: In a refrigerant heat exchanger 10, water which reserved in a water reservoir 8 after cooling a liquid refrigerant and consequently being heated, is fed through a pipe 12 into a water-generating portion 4 by a pump 11, to the thaw frosts formed in the water-geneating portion 4. The water whose temperature is lowered as a result is fed by a valve 13 through a pipe 7 into the refrigerant heat exchanger 10, where the water cools the liquid refrigerant and returns to the water reservoir 8. Water obtained at the water-generating portion 4 is chill, and used for supercooling the liquid refrigerant to a temperature lower than its saturation point, to operate a freezer in a supercooling cycle. Consequently, an electric power consumption can be saved by an amount cooresponding to the cooling heat which the water had.
