摘要:
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.
摘要:
A carbonate spring producing system includes a gas-liquid separator (6) which is connected on the downstream side of a carbonic acid gas dissolver (4). A carbonic acid gas supply means (10) and hot water supply means are connected to the carbonic acid gas dissolver (4). A liquid lead-out pipe (5) is connected to the gas-liquid separator. Preferably an un-dissolved carbonic acid gas lead-out pipe (23) is connected on the upstream sides of the gas-liquid separator (6) and the carbonic acid gas dissolver (4). The un-dissolved carbonic acid gas lead-out pipe (23) includes a control valve (25), a compressor (27), and a liquid level detection means (22). The control valve (25) controls a flow rate of un-dissolved carbonic acid gas from the gas-liquid separator. The liquid level detection means (22) measures a liquid level of the gas-liquid separator. Control means (28) controls the flow rate of the supplied carbonic acid gas and the flow rate of the supplied un-dissolved carbonic acid gas based on the gas-liquid separator liquid level detected by the detection means (22). An amount of un-dissolved carbonic acid gas in the gas-liquid separator is always monitored, so that the un-dissolved carbonic acid gas in the hot water can securely be separated and removed by the gas-liquid separator, and the separated and removed un-dissolved carbonic acid gas can be redissolved.

摘要:
It relates to equipment and a process for producing carbonated water of a high-concentration inexpensively and easily. Since the equipment for producing the carbonated water and the process for producing the carbonated water using a static mixer having 20 to 100 elements realize production of the carbonated water of the high-concentration inexpensively and easily, they can be applied particularly effectively for so-called one pass production process. Moreover, the carbonated water of a higher concentration can be produced further effectively by providing a value Re×N of 100,000 to 2,000,000, wherein N is a number of elements of the static mixer and Re is a Reynolds number when a mixture of water and a carbonic acid gas flow in the static mixer.

An object of the present invention is to provide a production apparatus for a hollow fiber membrane module without a risk of deteriorating characteristics of the hollow fiber membranes to be used, with the module case and the hollow fiber membranes bonded and fixed with a potting resin in a highly fluid-tight or airtight manner, and a production method thereof.A centrifugal type production apparatus (1) for the hollow fiber membrane module, for bonding and fixing at least one end part of the hollow fiber membrane stored in the module case and the module case with each other with the potting resin by utilizing a centrifugal force. The centrifugal force is applied by driving a centrifugal machine (11) while supporting an end part potting working part (3) of the hollow fiber membrane module (2) by a fixing jig (4). The fixing jig (4) comprising a heating means (7) and a temperature detecting means (8) controlling a heating capacity of the heating means (7) based on a difference between a temperature of the fixing jig (4) detected by the temperature detecting means (8) and a setting temperature of the fixing jig (4) preliminarily set in a temperature accuracy range of ±4° C. to the setting temperature. It is also possible to reduce a pressure of the potting working part (3) with a pressure reducing mechanism (17) simultaneously with the centrifugal force application for further preventing generation of leakage of the potting resin.

A boot for constant-velocity universal joint comprises a major-diameter cylindrical portion 2, a minor-diameter cylindrical portion 3 being separated away from and being put in place concentrically with the major-diameter cylinder portion 2, and having a smaller diameter than that of the major-diameter cylindrical portion 2, and an intermediate portion 10 connecting the major-diameter cylindrical portion 2 with the minor-diameter cylindrical portion 3. The intermediate portion 10 comprises a stretchable bellows portion 19 being connected with the minor-diameter cylindrical portion 3 integrally, and a rigidity-producing portion 11 being connected with the bellows portion 19 and the major-diameter cylindrical portion 2 integrally. The rigidity-producing portion 11 enlarges diametrically from the bellows portion 19 toward the major-diameter cylindrical portion 2, and additionally at least an outer peripheral surface 101 of the rigidity-producing portion 11 has a plurality of shoulders 61 in a stepwise manner. By means of the rigidity-producing portion 11, the rigidity at around the major-diameter cylindrical portion is enhanced, and thereby it is possible to suppress deformation at the time of assembling.
