An image forming apparatus includes a plurality of image carrier rollers placed on an inner circumferential side of an annular conveying path so as to face the annular conveying path and so as to be juxtaposed in a sheet conveying direction along the annular conveying path. Opposed rollers are provided on the outer circumferential side of the annular conveying path. The respective image carrier rollers and the opposed rollers which are in pressure contact therewith constitute pairs of transfer rollers, respectively. Imaging sections for forming intrinsic color images on surfaces of the respective image carrier rollers are provided. A sheet is introduced to the annular conveying path and is conveyed along the sheet conveying direction sequentially through nip sections of the pairs of transfer rollers, while the images formed on the surfaces of the respective image carrier rollers by the imaging sections are transferred one by one onto the sheet. The sheet with the images transferred thereon is released from the annular conveying path.

A system including a secure LSI 1 establishes a communication path to/from a server 3 (UD1), and receives a common key-encrypted program generated by encryption with a common key and transmitted from the server 3 (UD6 and UD7). The received common key-encrypted program is decrypted to generate a raw program, and the raw program is re-encrypted with an inherent key to newly generate an inherent key-encrypted program, which is stored in an external memory.

摘要:
A guide boss is provided in a diaphragm blocking the halfway portion of a channel; a valve disk is formed in the shape of a cylinder; the inner face of this cylinder-shaped valve disk is slidably engaged around the guide boss; and further, a valve port consisting of a plurality of long bores are formed in a diaphragm surrounding the guide boss. Thereby, fluid can responsively flow into the valve port when the valve disk is opened, and the follow-up of the fluid is accelerated.
