摘要： To obtain a fuel rail that maintains low hardness and good formability before being formed into a tube stock, can be made to easily form a thin absorbing wall surface, and has a high hardness and pressure resistance so as to be usable not only at a fuel pressure of 400 kPa or less, but also at a relatively high fuel pressure of 400 kPa or more. A fuel rail for port injection that is provided with a fuel pressure absorbing wall surface 1 and is used at a fuel pressure of 200 kPa to 1400 kPa. The fuel rail comprises an iron alloy that includes chemical components of C, Si, Mn, P, S, Nb, and Mo. The fuel rail has an internal volume of at least 60 cc and an amount of change in internal volume, when pressure is applied, of at least 0.5 cc/MPa. A bainitic structure can be precipitated by brazing the fuel rail in a furnace during manufacturing.

摘要： An external control type fan clutch device has a sealed housing with a torque transmission chamber incorporating a drive disk therein. The drive disk has an oil reserving chamber. The sealed housing is supported on a rotary shaft with the drive disk fixed thereto. A valve member (armature) controls opening and closing of an oil circulating flow passage hole provided on a side wall of the oil reserving chamber. The valve member has magnetism and is actuated by an electromagnet supported on the rotary shaft for opening or closing the oil circulating flow passage hole. A ring-like magnetic body is disposed between the electromagnet and the rotary shaft for efficiently transmitting a magnetic flux of the electromagnet to the armature of the valve member. The external control type fan clutch device achieves size reduction, weight reduction and power saving
