Title: Heat transfer device
Inventor: TAO TSUNEO
IPC: F24D7/00
Filed: 1993-07-26
Abstract: PURPOSE:To obtain a larger amount of heat transfer by providing a communicating hole of a check valve inside a gas-liquid separator to allow liquid medium in a receiver to flow into the gas-liquid separator within a short time period. CONSTITUTION:A communicating hole of a check valve 7 is provided inside a gas-liquid separator 3. Thereby, as the differential liquid level between a receiver 2 and the check valve 7 becomes large, the time period required for liquid medium in the receiver 2 to flow completely into the gas-liquid separator 3 can be shortened, so that a large amount of heat transfer can be obtained. Furthermore, as the liquid medium may flow into the gas-liquid separator 3 via the shortest route, the vertical arrangement of the receiver 2 and the gas- liquid separator 3 can be made small and compact. As the lower end of a double valve case 5 connected to the gas-liquid separator 3 is located above the communicating hole, resistance across the double valve case 5 becomes nil completely when the liquid medium flows out so that the time can be shortened further and a large amount of heat transfer can be obtained.

Filed: 1993-07-26
Abstract: PURPOSE:To form an electrode wiring layer composed of main constituent metal of metal oxide by subjecting a substrate to heat treatment in reduction gas atmosphere containing hydrogen or carbon thereby reducing the metal oxide. CONSTITUTION:A blancket type CuO film (metal oxide) 4 is deposited by 0.6mum on the entire surface through down flow CVD system. Impurities such as carbon or hydrogen are prevented from bonding to Cu by forming not a Cu film from the start but a CuO film 4 even when an organic source is employed as a material. Heat treatment is performed at 750mTorr and 500 deg.C for 30min in a reduction gas atmosphere of 20% H2 and 80% Ar to reduce the CuO wiring 4 thus completing a CuO wiring 5 composed of main constituent metal, i.e., Cu, of the CuO wiring 4. This method allows formation of electrode or metal wiring excellent in EM resistance and SM resistance without increasing electric resistance due to impurities.
