Abstract: The necessity of calculating a SaaS usage fee by a SaaS service provider is eliminated, and operation efficiency of the SaaS service provider is improved. When a SaaS user 10 uses a SaaS 14, the used volume thereof is accumulated in an operation-system database 21 through a SaaS execution infrastructure 17. When a usage-fee calculation date of the SaaS 14 comes, a business infrastructure 18 acquires used-volume information from an operation infrastructure 19 and calculates a usage fee of the SaaS 14 in accordance with application contents of the SaaS user 10 and usage cost of the SaaS execution infrastructure 17, the business infrastructure 18, and the operation infrastructure 19 used by the SaaS service provider 12 for realizing the SaaS 14.

Abstract: The metal vessel of the present invention is characterized in that a relief type hologram or relief type diffraction grating is formed on at least a part of the vessel by coining. By forming this hologram or diffraction grating by coining, the dimensional precision or reproducibility of the hologram of diffraction grating is highly improved. The metal vessel having the hologram formed thereon is excellent in the design and decorative characteristics, and in the metal vessel having the diffraction grating formed thereon, changes of the inner pressure can be easily detected by utilizing this diffraction grating.

Abstract: A metal vessel has a metal bottomed cup-shaped lower member and a metal cup-shaped upper member, the upper and lower members being bonded together by a circumferential side seam. The upper member has a pouring mouth having a small diameter in the central portion thereof. The metal vessel is formed by lap-bonding the circumferential open ends of both the upper and lower members. The side wall of the upper member is formed by subjecting a primer-coated tin-plated steel sheet to draw forming at a side wall plastic forming ratio R of from 1.1 to 1.8; the side wall plastic forming ratio R being defined by the following formula: ##EQU1## wherein W stands for the weight (g) of the blank of the upper member, t stands for the thickness (cm) of the blank of the upper member at the side wall, .rho. stands for the density (g/cm.sup.3) of the blank of the upper member, D.sub.0 stands for the inner diameter (cm) of pouring mouth of the upper member, and D.sub.1 stands for the average inner diameter (cm) of the side wall.

Abstract: Disclosed is a draw-ironed metal vessel having a circumferential side seam, which is formed by lap-bonding of open end portions of upper and lower members, each consisting of a seamless molded metal cap, wherein the side wall of at least one of said upper and lower members is formed by draw-ironing a tin-plated steel plate at an ironing ratio of at least 20% and a spout having a diameter smaller than that of the side wall of the vessel is formed on the top wall of the upper member.

Abstract: Disclosed is a side seam-coated welded can comprising a welded can body having a seam on the side face and a resin coating layer covering at least one surface side of the seam, wherein said coating layer comprises a thermosetting resin and a thermoplastic resin having a softening point of 50.degree. to 300.degree. C. as determined according to the ring and ball method, at a volume ratio ranging (A) from 95/5 to 25/75 or (B) from 20/80 to 1/99, and one of said two resins is present in the coating in the form of a continuous phase and at least a part of the other resin is present in the coating in the form of fine dispersed particles.This can is excellent in corrosion resistance and processability.
