Title: Manufacture of magnetic fluid
Inventor: NISHIKAWA TAKEO
IPC: H01F1/44
Filed: 1984-11-07
Abstract: PURPOSE:To obtain a magnetic fluid, in which Fe, Co and Ni of high content are dispersed and which has high performance, by installing a magnet to the bottom of an electrolytic cell and precipitating and accumulating the filmy deposit of a high magnetizing element formed on the surface of a dispersion medium by an electrolysis onto the bottom by the force of a magnetic field. CONSTITUTION:A Ga alloy 2 and an electrolyte 3 are admitted into an electrolytic cell 1, and a bidirectional magnet 4 is mounted adjoined to a bottom. An anode 5 is disposed to the electrolyte 3 and a cathode 6 to the Ga alloy 2. When the magnet is installed to the bottom of the electrolytic cell, the product of a thin-film consisting of Fe, Co and Ni formed on the surface of the alloy with an electrolysis is changed into ferromagnetic from super-paramagnetic by the magnetic line of force radiated from the magnet when magnetic force exceeds some magnitude. Consequently, the magnetic line of force of the bottom works, and the product is sucked to the bottom. Since alloy itself is composed of a paramagnetic substance, the alloy is replaced with sucked ferromagnetic substance particles and a vector separating from the magnet is generated, and the product moves to the surface layer section of the alloy. A fluid having weak magnetic sensitivity collects in the surface layer section at all times, and a substance having strong magnetic sensitivity accumulates on the bottom.

Title: Cooling and heating apparatus using heat of outside air
Inventor: SUMITA KUMOO
IPC: F24F5/00
Filed: 1988-09-20
Abstract: PURPOSE:To reduce the cooling load with maintaining the atmospheric conditions in a room by a method wherein in a plant cultivating facility, outdoor side and room side heat exchangers provided with a fan each are connected by heating medium pipes, and the heat of outside air is recovered by the heating medium and discharged into the room. CONSTITUTION:Brine as a heating medium is circulated by a heating medium circulating pump 3 along a heating medium pipeline 4 in the direction shown by the arrows, and at an outdoor side heat exchanger 1, the brine recovers the low temperature heat from outside air forcibly ventilated by a fan 1a. At a room side heat exchange 2, the brine, which has absorbed the low temperature heat of outside air, exchanges the low temperature heat with the room air forcibly ventilated by a fan 2a, thus releasing the heat. The air after passing through the room side heat exchanger 2 turns from warm wind to cool wind so that a house 6 is cooled. Therefore, as cooling of the room is carried out using the heat of outside air without contact between the inside air and the outside air, the cooling load especially in winter season can be reduced with maintaining the atmospheric conditions in the room such as the room temperature, humidity, gas concentration, etc.

Filed: 1990-09-06
Abstract: PURPOSE:To reduce the heat absorption at a waterwall of a furnace and raise the temperature of exhaust gas to reduce unburnt content by a method wherein the upper part of the furnace is surrounded by a steam-cooled wall. CONSTITUTION:The lower part of a furnace 8 is covered by a waterwall 9 and the upper part by a steam-cooled wall 27. Therefore, the feed water in a drum 6 flows down along a down-flow pipe 7, rises along the waterwall 9 extending from an inlet header 10 up to nearly the middle of the furnace 8, and flows out of an outlet header 11 to the drum 6 via connecting pipe 12. On the other hand, the steam in the drum 6 passes through a saturated steam pipe 13 and an inlet header 28, flows down along the steam-cooled wall 27, then to an outlet header 29, a steam pipe 30 and a mixing header 31 where it is mixed with steam coming from a cage wall 14, and finally into a primary heater 18 and a secondary heater 22. Thus, as the upper part of the furnace 8 is surrounded by the steam-cooled wall 27 through which stem flows, the heat absorption at the steam-cooled wall is reduced, resulting in a temperature rise of the exhaust gas. As a result, the unburnt content is reduced.
