Abstract: A service providing system includes a providing unit that delivers a dedicated ink cartridge to be installed in place of a non-dedicated ink cartridge that was installed in the multifunction machine 1 before subscribing to the service, a server memory that stores the amount of ink remaining in the non-dedicated ink cartridge, and a permission unit that permits printing using the dedicated ink cartridge according to the remaining amount of ink stored in the server memory when the user withdraws from the service.

Abstract: The invention provides a golf ball comprising a core of at least one layer, a cover of at least one layer, and optionally an intermediate layer therebetween, characterized in that at least one layer of the core, cover and intermediate layer is formed of a golf ball-forming resin composition comprising, in admixture, (A) 100 parts by weight of a polyether ester block copolymer composed primarily of (a) high-melting crystalline polymer segments made of crystalline aromatic polyester units and (b) low-melting polymer segments made of aliphatic polyether units and (B) 0.05–10 parts by weight of a polyisocyanate compound. Using the golf ball-forming resin composition which has flexibility and high rebound resilience and is fully wear resistant, the inventive golf ball is improved in travel distance, feel, scuff resistance and impact durability.

Abstract: A golf ball is formed with a resin composition which contains 5 to 95 weight % of a polyester block copolymer (A) and 95 to 5 weight % of an ionomer resin (B); and a (polyester-aromatic vinyl based copolymer) block copolymer (C), which is mixed with both the polyester block copolymer (A) and the ionomer resin (B) in an amount of 1 to 40 parts by weight on the basis of 100 parts by weight of the total of the polyester block copolymer (A) and the ionomer resin (B). The polyester block copolymer (A) mainly contains a high-melting point crystalline polymer segment (a1) composed of a crystalline aromatic polyester unit, and a low-melting point polymer segment (a2) composed of an aliphatic polyether unit and/or an aliphatic polyester unit. The ionomer resin (B) is produced by neutralizing a copolymer mainly containing an &agr;-olefine (b1) and an &agr;,&bgr;-unsaturated carboxylic acid (b2) having 3 to 8 carbon atoms with at least one metal ion (b3) selected from univalent, divalent, and trivalent metal ions.
