摘要： PURPOSE:To make a heat exchanging portion compact while facilitate the regulation of the mixing ratio of warm air/cool air by integrally forming the heat exchanging member of an air heater and the heat exchanging member of an air cooler in a multiple layer form and forming this into a cylindrically wound shape. CONSTITUTION:A refrigerant pipe 17 and a hot water pipe 18 are spirally provided in a vertically-placed spiral cooler/heater 16 which is installed in an air conditioner and in which an evaporator and a heater core are integrally formed. Also, a heat insulating board 19 is placed between both heat transfer pipes 17, 18, and fins 20c, 20h are provided between the heat insulating board 19 and each heat transfer pipe 17, 18. Air flows through these fins 20c, 20h. In order to regulate the quantity of warm air and cool air at the outlet of such cooler/heater 16, warm-air/cool-air regulators 21, 22 are provided. A spiral groove hole (the void portion) 33 is provided in a disk in each of the regulators 21, 22 and, by rotating the regulator 22, the negative detour opening area of the warm air zone is changed to regulate air temperature.

摘要： PURPOSE:To increase the efficiency in cooling Na, by arranging a partition plate made of a heat insulating material with both upper and lower ends opened on the side end part of the collector of the title cold trap to insulate the heat between the collector and the surrounding Na. CONSTITUTION:A mesh 1 is housed in a vessel 2, and the vessel 2 is also used as the passage of Na. A wick 22 is arranged on the outside of the vessel 2, and an annular space 25 surrounded with a heat insulating wall 24 is formed on the outside of the wick and forms a heat pipe. The upper part of the annular space 25 communicates with an upper space 26, a fin 19 is provided on the outside of the upper space 26, and the upper space is cooled by the cooling air by a fan 13. To facilitate the return of a liq. metal 23 condensed in the upper space to the wick 22, the partition plate 30 sloped toward the inside is provided to separate the insulating wall 24, the wick 22, and the upper space 26. The warming of the highly heat conductive Na can be prevented by the heat insulating partition plate 30.

摘要： PURPOSE:To simplify the structure and to enhance the efficiency of an annular magnetic field type electromagnetic fluid apparatus by forming a closed loop-like magnetic field in a conductive fluid, and employing the closed magnetic field as an external magnetic field generator of an electrode fluid apparatus. CONSTITUTION:A toroidal coil 24 is bundled at upper and lower ends of annular passage. The outside for connecting the annular passage of the inside for connecting with a generator side header 36 with a generator side passage 3 and a pump side header 35 is used as a pump side passage 2. An external magnetic field 20 exists circumferentially in the passages 2, 3 by the coil 24. Conductive fluid in the passage 2 undergoes a downward force to flow, and the conductive fluid in the passage 3 an upward force to flow.

摘要： PURPOSE:To obtain a power supply means which can be operated even under the high temperature condition and is capable of keeping the temperature constant even in case self-generation of heat occurs due to a heavy current by applying an electrical power to a conductive fluid while the conductive fluid is caused to flow within the path surrounded by an insulation material. CONSTITUTION:A coil 1 covered with an insulating material 6 is connected to the upstream side tank 3 and the downstream side tank 4. The tanks 3, 4 are respectively provided with apertures 7, 8. A liquid metal 5 is set in the upper tank 7, the electrode of power source 2 is connected to the inner wall of insulating material 6 in contact with the liquid metal 5 in the coil 1 in the vicinity of both ends of coil 1 and a current is applied to the liquid metal 5 flowing downward in the coil 1. The magnetic field can be generated by this current. The liquid metal 5 shows self-generation of heat only between both ends 10, 11 of a part of coil 1 where current flows. In case sodium is considered as the liquid metal 5 which is the conductive fluid, the coil 1 can be used in the temperature range as wide as 98 deg.C (melting point) to 878 deg.C (boiling point).

摘要： PURPOSE:To simply control fluid by providing a current suppressor to cause a current to flow to the magnetic circuit and to cause no current to flow to a current circuit when an electromagnetic fluid is stopped, thereby operating an electromagnetic brake action at stopping time. CONSTITUTION:In an AC Faraday type electromagnetic pump having a current circuit and a magnetic circuit perpendicularly crossing a duct 2, currents flow to the magnetic coil 10 of the magnetic circuit and the current transformer coil 7 of the current circuit when electromagnetic fluid is driven. When the fluid is stopped no current flows to the coil 7 and a current flows to the coil 10 by a current suppressor 13. Thus, since electromagnetic action is operated to the fluid at stopping time, it is not necessary to provide a mechanical movable portion such as a fluid regulating valve or a check valve to improve the reliability.
