  • Patent number: 10413897
    Abstract: An ion exchanger includes a case and an ion exchange resin. The case includes an inflow hole into which a refrigerant flows and an outflow hole out of which the refrigerant flows. The ion exchange resin is arranged in the case to remove ions from the refrigerant. The inflow hole and the outflow hole are located at a lower end of the case. The case accommodates a tube extending in a vertical direction and connecting to the outflow hole. The ion exchange resin is located between an inner wall of the case and an outer wall of the tube. The inflow hole is formed so that the refrigerant flows through the inflow hole into the case and evenly into the ion exchange resin from a lower end surface of the ion exchange resin.

  • Patent number: 9732315
    Abstract: A triiodide resin (TR) tube of the present invention has a cylindrical shape. A resin exhaust preventing part is provided at a lower portion of the TR tube, and a triiodide resin is received inside the TR tube. A contaminated culture passes through the TR tube to allow an axenic culture to flow out. When a microalgae culture contaminated with bacteria passes through the TR tube filled with the triiodide resin, a pure culture of microalgae can be prepared by using the sterilizing rate of bacteria populations, which is relatively higher than that of microalgae, due to characteristics of iodine exhibiting negative polarity.

  • Publication number: 20120000861
    Abstract: This invention aims at providing a beverage dispenser with a simple configuration that prevents invasion of bacteria into a tank or a raw water container. An air intake 13 is provided on the top of a cold tank 4 so that air is taken in as water level in the tank is lowered, and an air chamber 14 having an air inlet 16 for the outside air is connected to the air intake 13. In the air chamber 14, an ozone generator 15 generating ozone from oxygen in the air from the air inlet 16 is provided so that bacteria included in the air from outside is killed in the air chamber 14 connected to the air intake 13 by excellent bactericidal effect of ozone. Invasion of bacteria into the tank or the raw water container is thus prevented with this simple configuration.

  • Publication number: 20110215048
    Abstract: The present invention is directed to a fluid flow control assembly for regulating fluid flow, and may find particular application in additive dispenser systems. Typically a baffle arrangement (210) comprises a plurality of baffle elements (202) within a chamber (208). The arrangement forms an alternating sequence of restrictions and cavities for fluid flowing from an inlet (205) to an outlet (201) and tends to restrict fluid flow in an alternative manner to merely providing a fine diameter aperture. The fluid flow control assembly was developed for applications where foreign particles or air bubbles may block fine diameter apertures, such as low pressure additive dispenser systems where low relatively stable flow rates are important to their operation.

  • Publication number: 20110168623
    Abstract: A feed side passage material is provided in which sufficient antibacterial activity is obtained even in the spaces among constituent yarns and which hence can effectively prevent biofouling. Also provided is a spiral separation-membrane element employing the feed side passage material. The feed side passage material, which is for use in a spiral separation-membrane element, is a feed side passage material in a net form constituted of yarns (1 and 2) containing a chlorophenol compound antibacterial. The spiral separation-membrane element comprises a perforated hollow core tube and, wound therearound, one or more separation membranes, one or more feed side passage materials, and one or more permeate side passage materials. The element is characterized in that the feed side passage materials each is said feed side passage material.
