A user machine is made aware of a need for communication to update a version of a firmware by communication from a service center (a notification that the latest version has been released). After shutting off this communication once, communication is carried out between the official service center and the user machine by the user machine commencing communication with the official service center, the contact information of which is stored, and the service center provides information for updating the new version to the user machine in this communication state.

The invention aims to provide a torque rod which, by adding an improved rod portion, has not only compression and tensile strength, but also increased bending and twisting stiffness. By the present invention, the twisting stiffness can be raised to 2 to 3 times that of a conventional rib shape. A torque rod, the torque rod structure comprising a rod portion with a built-in pair of rubber bushes, which are formed respectively around a pair of cylinders, the rod portion linking both the rubber bushes, wherein the cross-sectional shape of the central portion of the rod portion forms a rectangular shape and one pair of opposing edges of the rectangular shape form a shape which bulges outwards, and the cross section of the rod portion is one of a hollow portion, honey comb shape, or rib structure. 11, 12 . . . internal cylinders, 20 torque rod, 21 . . . hollow portion.

A CPU includes a bus interface, a control unit, an instruction cache, a data cache, a secondary cache, an instruction decoder, an arithmetic unit, and registers. When operations can be performed only with the cache, the CPU inhibits access to external memory and stops power supply to the external memory. With this arrangement, by performing operations in the CPU without using the external memory, it is possible to realize a speedy processing and to stop power supply to the external memory, thus allowing for reduction in power consumption.

An image forming apparatus is provided which is capable of storing image data regardless of remaining free area of a memory associated with a specified function. The digital image forming apparatus comprises a facsimile memory for storing transmission/reception data by a memory transmission/reception function of a facsimile, a copying memory for storing copying data by a copying/printing function or externally inputted data, and a compression/expansion converting section which converts transmission/reception data stored in the facsimile memory by the memory transmission/reception function into data suitable for communication via a communication line, wherein a CPU working as storage control means is disposed which, when storing data by one function of a plurality of functions into a memory associated with the function, stores the data into a memory associated with another function in the case where all the data cannot be stored into the associated memory.

An ASIC (semiconductor device) of an image processing section is provided with an input/output circuit for performing input and output to and from an image processing circuit and a confidential circuit. The input/output circuit performs output to outside of the ASIC at a timing shifted from a timing of output from the confidential circuit, for example, so as to hide the processing of the confidential circuit. With this arrangement, it is possible to hide an algorithm in the confidential circuit. Further, the ASIC is provided with a decryption circuit for decrypting an encrypted program stored in a nonvolatile memory provided separately from the ASIC. The decryption circuit is caused to function as a decryption section upon later-writing into an OTP.
