Abstract: A version table (11a) recording therein information indicative of an execution program (22a) and version number information indicative of a version number of a version of the updatable execution program (22a) in association with each other is provided in a central device (1). In a terminal device (2), an instruction accepted for the execution program (22a) is detected, the version number of the version of the execution program (22a) as the target of the instruction is detected, the version number indicated by the version number information of the execution program (22a) is read from the version table (11a), and the execution program (22a) is updated when it is determined that the detected version number and the read version number are different from each other.

Abstract: Ultradispersed ones of primary particles of nanometer-sized carbon are obtained by applying a wet-type milling method and/or a wet dispersion method to an aggregate structure of the primary particles to overcome van der Waals forces, by which forces the primary particles are held together to form the aggregate structure, whereby the ultradispersed primary particles are obtained in a colloidal dispersion on a large-scale basis at low cost without using any additive. In a method of manufacturing the ultradispersed primary particles, the wet-type milling method is carried out in a ball mill, preferably in combination with a high-energy ultrasonic-wave process carried out in a dispersing medium such as pure water, whereby a colloidal solution or slurry with a low-concentration of the primary particles ultradispersed in the dispersing medium is obtained.
