摘要： An SiC film having an excellent strength and thermal characteristics. The SiC film is prepared by a CVD process (i.e. CVD-SiC fabrication) and has a thermal conductivity along the direction of the SiC crystal growth between 100 and 300 W/m.multidot.K, and an average grain diameter of the internal structure between 4 to 12 .mu.m. It is preferred that the ratio of the thermal conductivity along the direction of the SiC crystal growth to the thermal conductivity in the perpendicular direction is in a range of 1.10 to 1.40.

摘要： A reed type valve is operatively secured on the outer surface of the casing of an engine air filter assembly to supply the exhaust system of an engine with secondary air. The reed valve is fluidly connected to an air induction passage formed inside the casing of the air filter assembly. A resonance chamber is also formed inside of the casing and communicates through a communication passage with the air induction passage so as to attenuate a relatively low frequency component of exhaust noise transmitted through the reed valve. The air induction passage, resonance chamber and communication passage are formed as follows: ##EQU1## where, S.sub.o (cm.sup.2)=the cross-sectional area of the air induction passageS(cm.sup.2)=the cross-sectional area of the communication passagel(cm)=the length of the communication passageV(cm.sup.3)=the volume of the resonance chamberM=the number of the engine cylinders of the engine.
