Abstract: An information management method collects log information of one or more home electrical apparatuses corresponding to service providers. Display screen data is generated which indicates a status of the log information. The display screen data includes groups of information which each contain information on an apparatus, a service provider corresponding to the apparatus, and log information output from the apparatus. Provision of the log information of each group is individually selectable. The display screen data is provided via a network to a display terminal that performs access to a server device. Information is received from the display terminal, which indicates that selection on whether or not provision of the log information is performed. Provision of the log information is not performed on the selected group when a determination is made that refusal of provision of the log information on the selected group is performed.

Abstract: A water and oil repellent composition consisting essentially of a copolymer comprising the following polymeric units A, B, C and D, and an organic solvent:Polymeric units A: Polymeric units derived from an acrylate containing a polyfluoroalkyl group, and/or a methacrylate containing a polyfluoroalkyl group;Polymeric units B: Polymeric units derived from an acrylate containing a hydrocarbon group, and/or a methacrylate containing a hydrocarbon group;Polymeric units C: Polymeric units derived from an acid anhydride having an unsaturated group; andPolymeric units D: Polymeric units derived from triallyl cyanurate.
