摘要: A silicon steel sheet having low iron loss of high frequency has a surface layer of the steel sheet which has Si concentration higher than Si concentration of a center portion of the steel sheet. Si concentration of sheet thickness center is 3.4 wt. % or more and Si concentration of the surface layer of the steel sheet is 5 wt. % or more. Si concentration in a surface layer portion is 5 to 8 wt. %. The production method comprises siliconizing treatment and diffusing treatment. Velocity of siliconizing and diffusing are controlled, and Si concentration distribution in the sheet thickness direction of the steel sheet is controlled.

摘要: A vehicle suspension mechanism including a carrier for carrying a rear wheel rotatably about an axis of rotation, a strut assembly having an upper end connected with a vehicle body and a lower end connected with the carrier, a swingable arm pivotably connected through resilient rubber bushes with the vehicle body at a longitudinally spaced first forward point and a first rearward point and with the carrier at a longitudinally spaced second forward point and a second rearward point. The aforementioned points are arranged so that the distance between the line connecting the first forward and first rearward points and the line connecting the second forward and second rearward points increases toward the rearward direction, whereby a toe-in movement is produced when the arm is upwardly swung.
