摘要： PURPOSE:To manufacture an iron series sintered alloy for a valve seat excellent in wear resistance, heat resistance and high temp. corrosion resistance. CONSTITUTION:Since 3 to 30% Co, Ni Mn or V is entered into solid solution in an Fe series base structure contg., by weight, 0.3 to 1.5% C and constituting a matrix, its strength is improved and also excellent heat resistance and corrosion resistance can be obtd. Furthermore, since Fe-Mo and Fe-W as hard grains, are dispersed into the base structure by 3 to 15%, its wear resistance can be improved. Moreover, as a solid lubricant, by dispersing CaFe2, MoS2 or MnS, its seizing resistance and machinability can be improved, and since its upper limit is regulated to 2.0% and also the opening porosity of a sintered body is regulated to

摘要： PROBLEM TO BE SOLVED: To provide a flow-through type PM trapping device having a higher PM trapping rate. SOLUTION: The PM trapping device comprises a charging part for charging PM, and a trapping part for trapping the charged PM with electrostatic force. The trapping part has a coat layer 13 formed of a magnetic substance. The track of the PM is changed by the magnetic field of the coat layer 13 to expectedly reduce a speed of collision with the trapping part. This suppresses the fly of non-trapped PM with the reaction during collision and suppresses the re-fly of the trapped PM with the impact during collision. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PURPOSE:To provide a valve seat composed of a sintered body including lead as a lubricant in high temperature in an internal combustion engine, which can maintain the lubricating action of the lead for a long period. CONSTITUTION:A valve seat 10 is composed of two layers, i.e., a valve contacting layer 10b contacting a valve 2 of an internal combustion engine and a layer 10a rich in lead and sintered integrally with the valve contacting surface 10b. The valve contacting layer 10b is composed of a sintered body having 7.2-7.5g/cm of density and lead infiltrated therein. The layer 10a rich in lead is composed of a sintered body having 6.6-7.0g/cm of density and lead infiltrated therein. Since the valve contacting layer 10b has the high density and small empty holes, a proper amount of lead is supplied from the surface of the layer 10b when the temperature of the valve seat 10 exceeds the melting point of the lead.
