Filed: 1992-11-26
Abstract: PURPOSE: To provide a novel fullerene derivative capable of being used as a polymer stiffener, a polymer blended material, a cross-linking agent of polymer and/or a constituent for a star polymer.  
     CONSTITUTION: This derivatized fullerene is expressed by a formula (C x N u ) n  ((n) represents 2, 4 or 6, N u  represents a nucleophilic group produced as the result of trapping an oxidized C x  by a uncleophilic reagent and C x  represent a fullerene), e.g. di- tetra- or hexa-methoxylated C 60 . The compound is produced by allowing fullerene to contact with the oxidizing agent such as a strong acid and/or a super acid to generate a cationic group (fulleronium ion) and inactivating the cationic group with the nucleophilic reagent selected from an aromatic compound, a thiol or an alcohol containing a substituent to be added. In such a case, a terminal 1,y-difulleroalkane is obtained by being trapped by a terminal 1,y-diol ((y) represents the carbon numbers of the diol). And the fullerene derivative having odd numbers of substituents is formed by heating a fullerene derivative having even numbers of substituents.

Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To prevent drying of the heat-exchanger of an indoor unit by a method wherein the opening of a motor-drive expansion valve situated in a refrigerating cycle is properly controlled. SOLUTION: In an air-conditioner, when a compressor is operated, an operation degree D-dis is computed from a discharge temperature T-dis and a preceding target discharge temperature TGT-dism. When the absolute value of the computed operation degree D-dis attains a given range, a dry degree D-sh is computed from a charge temperature T-sh and a coil temperature T-coil (at steps 200-204). Thereafter, an operation amount USH is set from the computed operation degree D-dis and the dry degree D-sh to determine a correction amount CSH (at steps 206-214). Based on a target discharge temperature Tgt-dis corrected by a discharge temperature Tgt-dis computed by the correction amount CSH, the opening of the motor-drive expansion valve is controlled.
