Abstract: Provided is a method that can produce an inexpensive rubber composition capable of providing a rubber elastic body having high strength. A method for producing a rubber composition of the present invention includes steps of: (A) kneading a component containing at least a highly saturated conjugated diene-based polymer and a crosslinking agent component; (B) kneading a component containing at least a conjugated diene-based polymer other than the highly saturated conjugated diene-based polymer; and (C) kneading an intermediate composition (a) obtained in the step (A) and an intermediate composition (b) obtained in the step (B).

Abstract: A diagram management server for a train line stores user information defining a relationship between a login user and an authority level; train line information; and authority setting information defining a relationship between a creation person having edit authority of the train line and an upper user in a database. When the login user is defined as an upper user of the creation person having the authority setting, a diagram edit terminal requests registering and updating of the train line information created by the creation person, based on the authority level of the login user, and the diagram management server resisters and updates the train line information. Then, from the database, the diagram edit terminal acquires and displays the train line information that the login user has the authority to edit.
