Abstract: An information processing system includes a first apparatus, multiple second apparatuses, and a server. The first apparatus receives authentication information from a user and transmits the authentication information to the server. If the user has been authenticated in accordance with the authentication information, the server transmits, to the first apparatus, permission information that indicates two or more second apparatuses that the user is permitted to use from among the second apparatuses. The first apparatus stores the authentication information while transmitting the authentication information to the second apparatuses. If the authentication information indicates one of the second apparatuses, the one of the second apparatuses performs an operation related to use of the one of the second apparatuses.

Abstract: An information processing system includes a first apparatus, a second apparatus providing a service for fee, and a server. The first apparatus transmits, to the server, identification information and settlement destination information in an associated form, the identification information identifying use of the service, the settlement destination information stored on the first apparatus and identifying a settlement destination of a usage fee for the use of the service. The second apparatus transmits to the server the identification information and fee information in an associated form, the fee information indicating the usage fee for the use identified by the identification information. The server settles the usage fee indicated by the fee information at the settlement destination identified the settlement destination information associated with the identification information.

Abstract: An information processing apparatus includes a processor configured to: acquire first permission information indicative of an apparatus which a first user is permitted to use, permit the first user to use the information processing apparatus in a case where the first permission information indicates the information processing apparatus, and permit the first user to use the information processing apparatus in a case where the first permission information does not indicate the information processing apparatus and a second user having an attribute that is in a predetermined relationship with an attribute of the first user is permitted to use the information processing apparatus.

Abstract: In a method of producing manganese dioxide for a lithium primary battery, heat treatment for dehydrating water-containing manganese dioxide is carried out by continuously calcining the water-containing manganese dioxide at 440.degree. C. to 480.degree. C., preferably by controlling the flow rate of air introduced into the furnace to the value of from 20 to 2000 Nl per 1 kg water-containing manganese dioxide which is supplied into the furnace. According to this method, the residual bound water in the calcined manganese dioxide is reduced as compared those treated with a conventional method, and thus preservation property of a battery can be improved.
