Patent number: 8157248Abstract: A carbonate spring producing system includes a gas-liquid separator which is connected on the downstream side of a carbonic acid gas dissolver which connects to a carbonic acid gas supply means and hot water supply. A liquid lead-out pipe is connected to the gas-liquid separator. Preferably an un-dissolved carbonic acid gas lead-out pipe is connected on the upstream sides of the gas-liquid separator and the carbonic acid gas dissolver. The un-dissolved carbonic acid gas lead-out pipe includes a control valve, a compressor, and a liquid level detection means. The control valve controls a flow rate of un-dissolved carbonic acid gas from the gas-liquid separator. An amount of un-dissolved carbonic acid gas in the gas-liquid separator is monitored, so that the un-dissolved carbonic acid gas in the hot water can be separated and removed by the gas-liquid separator. The separated and removed un-dissolved carbonic acid gas can be re-dissolved.Type: GrantFiled: December 23, 2010Date of Patent: April 17, 2012Assignee: Mitsubishi Rayon Co., Ltd.Inventors: Satoshi Suzuki, Ken Ooyachi, Hiroki Sakakibara, Masaaki Satou, Masanori Itakura, Hiroshi Tasaka

Patent number: 8096532Abstract: Hot water is pumped by a suction pump and introduced into a carbon dioxide (CO2) gas dissolver through solution flow rate adjusting means and then poured into a bath. The CO2 is introduced into the CO2 gas dissolver through gas flow rate adjusting means, and the quantity of bubbles in an artificial carbonated spring in a take-out pipe is measured. The solution and gas flow rate adjusting means are controlled via a control device using a relationship expression between a preliminarily set quantity of bubbles and carbon dioxide concentration to obtain a desired concentration of carbon dioxide gas in the carbonated spring. Since the carbon dioxide gas flow control means is provided between the carbon dioxide gas dissolver and a carbon dioxide gas supply source, a high concentration carbonated spring can always be manufactured, even if the pressure of supplied carbon dioxide gas changes or membrane permeation changes.Type: GrantFiled: June 27, 2008Date of Patent: January 17, 2012Assignee: Mitsubishi Rayon Co., Ltd.Inventors: Hiroki Sakakibara, Ken Ooyachi, Hiroshi Tasaka
