Abstract: A device management system includes a database and a request acceptance portion which accepts a connection request from a device. The connection request is a request for causing the request acceptance portion to execute access to the database. When the connection request is accepted from the device, the request acceptance portion sets a restriction rate according to a load amount of the database and selectively executes, by a ratio corresponding to the restriction rate, processing of permitting access to the database and processing of not permitting access to the database and notifying the device of an error.

Abstract: A polyimide precursor solution contains resin particles and a polyimide precursor. The resin particles in the polyimide precursor solution have a volume particle size distribution with one or more peaks. The volume frequency of a peak having the highest volume frequency of the one or more peaks accounts for 90% to 100% of the total volume frequency of all peaks of the volume particle size distribution.
