摘要:
A composition that includes a high-valent compound of copper, silver or indium; a linear, branched or cyclic C1-18 alcohol; and a Group VIII metal catalyst forms a metal film of copper, silver or indium on a substrate when the composition is coated on the substrate and heated to reduce the high-valent compound. The composition may alternatively include metal particles of silver, copper or indium in which the surface layer of the particle includes a high-valent compound of copper, silver or indium. A metal film of copper, silver or indium may also be formed on a substrate by coating a substrate with the composition including the metal particles, and heating to reduce the high-valent compound in the same manner as above.
摘要:
To provide a composition with which a metal film can be directly produced from a high-valent metal compound, a method for producing a metal film, and a method for producing a metal powder.Using a composition for production of a metal film of copper, silver or indium, which comprises a high-valent compound of copper, silver or indium, a linear, branched or cyclic C1-18 alcohol and a Group VIII metal catalyst, a coating film is formed, followed by reduction by heating to produce a metal film of copper, silver or indium. Further, using metal particles of silver, copper of indium having a surface layer comprising a high-valent compound of copper, silver or indium, instead of the high-valent compound of copper, silver or indium, a metal film of copper, silver or indium is produced in the same manner as above.

An object of the present invention is to provide a method for producing a Group IV metal oxide film useful as a semiconductor element or an optical element at a low temperature. The present invention relates to a method for producing a Group IV metal oxide film, comprising coating a surface of a substrate with a film-forming material dissolved in an organic solvent, and subjecting the substrate to a heat treatment, an ultraviolet irradiation treatment, or both of these treatments, wherein a film-forming material obtained by reacting a vinylenediamide complex having a specific structure with an oxidizing agent such as oxygen gas, air, ozone, water and hydrogen peroxide is used as the film-forming material.

According one embodiment, an air-conditioning system is connected to a server room, in which server racks accommodating a plurality of servers are placed between separated first and second spaces, by a return air duct and a supply air duct. In the server room, an airflow is formed so that cold air flown from under the floor into the first space is heated by heat generation of the servers and is flown out from the second space as return air. The system sets control contents for generating supply air within a previously determined supply air temperature target range and a previously determined supply air humidity target range and controls the operation of each device in the system based on the set control contents.

Some embodiment includes an air conditioner, an air blower, a sensor, and a controller. The air conditioner works for supply to cold spaces. The air blower produces streams of air in and between a server room and an air conditioning system. The sensor takes a measure of current or power as consumption at servers. The controller operates on the measure at the sensor, to control the air blower.

An embodiment includes a first space, a second space, a first damper, a second damper, and a third damper. The first space is connected to a cold space, having cold air reside therein to send to the cold space. The second space has return air reside therein, as it is discharged from a hot space. The first damper has an opening adjusted under control of a controller to take in outdoor air to the first space, and is operable to have an open state in an emergency with a server being supplied with power. The second damper has an opening adjusted under control of the controller to discharge return air in the second space, outside thereof, and is operable to have an open state in the emergency. The third damper has an opening adjusted under control of the controller to recirculate return air in the second space to the first space.

In accordance with embodiments, a server room managing air conditioning system includes: a first coil; a second coil; and an air supply fan. The first coil adjusts returned air of a server room to a predetermined temperature value lower than a supplied air temperature target value and dehumidifies the returned air. The second coil adjusts the returned air of the server room to a predetermined temperature value higher than the supplied air temperature target value so that the supplied air temperature target value and a supplied air humidity target value can be achieved when the returned air is mixed with air adjusted by the first coil. The air supply fan mixes the returned air and supplies the mixed returned air as the supplied air to the server room.

In an embodiment, an air conditioning system for managing a server room, which has first and second spaces separated from each other, in which a server is installed between the first and second spaces, and supply air flowed into the first space is heated by heat generation of the server, and flows out as return air via the second space, includes: a cold air generation device; an air supply fan; a first differential pressure gauge; and a control device. The cold air generation device generates supply air satisfying a predetermined condition. The air supply fan flows the generated supply air into the first space. The first differential pressure gauge measures a differential pressure of a static pressure of the second space with respect to a static pressure of the first space.
摘要:
A system for a server room management includes an air-conditioning control device including: an acquisition unit; a setting unit that sets content for generating supply air at temperature, absolute humidity, and relative humidity within target range, based on outside air temperature and humidity as well as return air temperature; and a controller controlling amount of outside air, amount of return air, control amount of humidifier, control amount of cooler, and amount of air blown by blower, based on the content. If the outside air is within range greater than absolute humidity upper limit, or within range greater than enthalpy upper limit and greater than the temperature upper limit, the setting unit compares outside air and return air, and then determines, in accordance with the comparison, whether to set the content so that the cooler performs cooling by minimizing or maximizing the amount of the outside air.
