Abstract: There is described an image forming apparatus that serves as a client in the client/server type information processing system. The apparatus includes a communicating section to communicate with the server; a device information acquiring section to acquire device information for specifying the device; an information storing section to store server information for specifying the server and client information for specifying the client itself; and a control section to transmit the device information, acquired by the device information acquiring section, and the client information, stored in the information storing section, to the server specified by the server information through the communicating section, in order to request the server to send an application program corresponding to the device information back to the client. When the control section receives the application program from the server, the control section develops the application program into the storage so as to make the device available.

Abstract: A roll forming apparatus has an elevatable base that is moved up and down by an elevating mechanism. Carriages are movably mounted on the base on both sides of a forming pass line. Each carriage carries several side rolls that are disposed along the forming pass line. A pair of side roll position adjusting mechanisms are coupled to each carriage. The pair of side roll position adjusting mechanisms move a carriage back and forth to form the desired forming pass. An elevating mechanism is provided to move up and down the base so that the level and inclination of the forming pass line is set as desired.
