At least one of the cation exchange composition body and the anion exchange composition body is configured to contain a thermally infusible additive.

Abstract: An electrochemical cell according to the present disclosure includes a casing provided with an inflow port and an outflow port, a bipolar membrane laminated body in which two or more bipolar membranes are laminated so as to be opposed, electrodes disposed so as to sandwich the bipolar membrane laminated body, and a first diffusion member disposed between the inflow port and the bipolar membrane laminated body, and provided with through holes communicating between the inflow port and the bipolar membrane laminated body. The first diffusion member is formed such that each of the through holes provided in a peripheral edge portion has a larger opening area than an opening area of the through holes provided in a central portion. This can uniformize a flow of water, so that water treatment can be efficiently executed.

Abstract: A water treatment apparatus of the present disclosure includes an electrochemical cell provided with an inlet and an outlet, a power supply that supplies electric power to electrodes, a first water flow path connected with the inlet, a second water flow path connected with the outlet, a soft water supply unit that feeds soft water to the inlet, and a flow adjustor that regulates a flow rate of water passing through the second water flow path. The water treatment apparatus further includes a controller that controls electric power supplied from the power supply to the electrodes, the flow rate of water passing through the second water flow path by use of the flow adjustor, and soft water fed to the inlet by use of the soft water supply unit when a process for regenerating the electrochemical cell is executed. As a result, the apparatus can reduce the hardness and electric conductivity of water fed into the electrochemical cell during regeneration of an ion exchange membrane and restrain scale formation.

Abstract: A browning of a frozen food is prevented, when a frozen food is unfrozen. A method of freezing food, which includes a process of freezing food (S206 to S210), and a process of increasing a temperature of the food up to an enzyme deactivation temperature at which the enzyme browning the food is deactivated (S201 to S205), which is performed before the freezing process.

Abstract: A compact and highly controllable impedance-varying-unit, a microwave device using the same unit, and a high-frequency-heating appliance using the same unit are provided. The impedance varying unit includes a rectangular waveguide-section as a main body made of metallic material, an open end of waveguide-section working on microwave in a microwave cavity, a terminal end of waveguide-section closed by metallic material, a rotary movable body made of non-metallic material, and a driver for the movable body. A rotating angle or a position of the movable body is controlled, so that an impedance at the open end is varied and transmission status of microwave is changed, thereby variably controlling a standing wave distribution. Controlling the standing wave distribution allows an object in the cavity to be selectively heated or uniformly heated. Further, the standing wave produced in the microwave cavity is sequentially varied, so that the object can be selectively heated or uniformly heated.
