摘要:
According to one embodiment, a system is provided, which provides moving picture data representing a road-traffic state. This system synthesizes the moving picture data with additional data such as advertisement data, generating output data. The system distributes the output data to the facilities built along the road and the vehicles running on the road.
摘要:
A fuel-filler tube, which is made of a welded pipe of corrosion-resistant austenitic or ferritic stainless steel, has a fuel-supply opening with high dimensional accuracy. The austenitic stainless steel has hardness of 180 HV or less with a work-hardening coefficient of 0.49 or less. The ferritic stainless steel has Lankford value of 1.2 or more with elongation of 30% or more by a uniaxial tensile test.

Disclosed is a ferritic stainless steel for hot-water tanks with welded structure, comprising, in terms of % by mass, at most 0.02% of C, from 0.01 to 0.30% of Si, at most 1% of Mn, at most 0.04% of P, at most 0.03% of S, from more than 21 to 26% of Cr, at most 2% of Mo, from 0.05 to 0.6% of Nb, from 0.05 to 0.4% of Ti, at most 0.025% of N, and from 0.02 to 0.3% of Al, and optionally containing at least one of at most 2%, preferably from 0.1 to 2% of Ni and at most 1%, preferably from 0.1 to 1% of Cu, with a balance of Fe and inevitable impurities.
摘要:
A fuel tank for a motor vehicle is fabricated from an austenitic stainless steel sheet having elongation of 50% or more after fracture by a uniaxial stretching test with a work-hardening coefficient of 4000 N/mm2 or a ferritic stainless steel sheet having elongation of 30% or more after fracture with Lankford value of 1.3 or more. The stainless steel sheets are reformed to a complicated shape of a fuel tank without work flaws such as cracks or break-down. Excellent corrosion-resistance of stainless steel itself is maintained in the fabricated fuel tank. Consequently, the proposed fuel tank is used without diffusion of gasoline to the open air over a long term.

摘要:
A fuel tank and a fuel-filler tube, which maintain excellent corrosion-resistance over a long term even in a severely corrosive atmosphere, is made of a ferritic stainless steel sheet good of formability. The steel sheet, which has elongation of 30% or more after fracture by a uniaxial tensile test and minimum Lankford value (value-rmin) of 1.3 or more, is formed to a product shape, and paint is cathodically electrodeposited on a surface of the formed stainless steel sheet. The stainless steel sheet may be one coated with an Al or Zn plating layer. When the fuel tank or fuel-filler tube is fabricated by welding, Zn-rich paint is preferably applied to a welded part in prior to cathodic electrodeposition coating.
摘要:
Stainless steel sheets are plated with zinc and further phosphated so as to have chromaticness indices of L=45-53, a=0.0-0.4 and b=1.3-4.4. Thus treated stainless steel sheets have sufficient strength, excellent corrosion resistance and a color well harmonizing with other building materials and environment and do not suffer from color change for a prolonged period of time.
