Abstract: A method of manufacturing porous ceramics, for example, thin film used for gas separation is disclosed. In this method, a silicon based mixture polymeric material which is the ceramics precursor is applied on a ceramics substrate, crosslinked by using ionizing radiation under oxygen free conditions; and pyrolyzed under an inert gas after that.

Abstract: In a hermetic compressor in a freezing refrigerating system or an air-conditioning system such as a refrigerator or a showcase, a construction is disclosed for intending to provide a low-noise hermetic compressor by effectively attenuating a pressure pulsation having occurred in a compression chamber with a suction muffler. By this construction, since a muffler cover 20 has a planar simple shape, the deformation upon molding becomes little and it can come into fully close contact with a muffler main body 19. Therefore, the pressure pulsation hardly leaks through the connecting portion between the muffler main body 19 and the muffler cover 20. The full silencing effect that the suction muffler 18 has is obtained and thereby noise can be reduced more effectively.

Abstract: (S)-(?)-4-[(4-chlorophenyl)(2-pyridyl)methoxy]piperi-dine represented by the formula (IV): wherein * represents an asymmetric carbon.
