Inventor: ABE RIKIYA
IPC: C01B33/107
Filed: 2003-07-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide silicon tetrafluoride to be a raw material for manufacturing high purity silicon from a powdery raw material containing silicon dioxide with a simple process without necessitating a large quantity of energy at high temperature and a method of manufacturing silicon tetrafluoride.  <P>SOLUTION: The silicon tetrafluoride is manufactured by taking out a produced gas containing silicon tetrafluoride by the chemical reaction treatment in which the powdery raw material containing silicon dioxide is blended with fluorite (CaF<SB>2</SB>) and concentrated sulfuric acid is dropped thereinto under heating, dehydrating and cooling the produced gas to condense, liquefy and separate silicon tetrafluoride. In the cooling, after being cooled to equal to or below 19°C to condense and separate a hydrogen fluoride portion in the produced gas, the produced gas is cooled again to ≤-65°C at which silicon fluoride portion is condensed to condense and separate a silicon fluoride portion.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: F25B41/06
Filed: 2003-07-24
Abstract: <P>PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of preventing the performance from being impaired by the shortage of a flow rate of refrigerant under low load of an ejector cycle (low temperature inside air mode).  <P>SOLUTION: A controller 10 controls a variable restriction mechanism 7 to an open side in a case when the discharge pressure Ph detected by a discharge pressure sensor 8 is less than a first specific pressure P1, and recovers the normal control when the discharge pressure Ph becomes more than a second specific pressure P2. As the reduction of driving flow is not found by controlling the variable restriction mechanism 7 to a fully open state or to the specific opening near the almost fully open when the discharge pressure Ph becomes less than the specific pressure, the recoverable decompression loss energy can be reasonably secured, and the sufficient flow rate can be achieved at a suction flow side. That is, the necessary cooling performance can be secured by an evaporator 6 even when the maximum coefficient of performance COP is not achieved.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
