A process cartridge detachably mountable to a main assembly of an electrophotographic image forming apparatus includes an electrophotographic photosensitive drum; a process device actable on the electrophotographic photosensitive drum; a memory element for storing information relating to the process cartridge; a connector including a plurality of connecting contacts, arranged along a line substantially perpendicular to a longitudinal direction of the electrophotographic photosensitive drum, for electrical connection with the main assembly to transmit to the main assembly information stored in the memory element when the process cartridge is mounted to the main assembly, wherein a connecting contacts of the plurality of connecting contacts which is closest to the electrophotographic photosensitive drum is a contact for electrically grounding a substrate of the memory element.
摘要:
A battery temperature regulating device is applied to a battery pack configured by parallely connecting battery groups, each of which is a series connection of battery cells capable of charge and discharge. The device regulates temperatures of the battery groups. The battery temperature regulating device includes a heat transfer unit that transfers heat of a part of the battery groups to another battery group.

When license information is transferred between a server machine and a client machine, an identifier which is unique to a series of communication sequences is provided. The identifier is sent when a communication is performed between the two machines, as well as when the license information is updated. Therefore, when a message for transferring the license information is received by the use of the same identifier, a response message is returned without updating the license information.

A management device of a license management system acquires a usage request of a content from an SD card or a printer via a relay device, analyzes the acquired usage request, acquires usage environment information of the SD card or the printer from the relay device, analyzes the acquired usage environment information, generates license information including a usage rule corresponding to the analysis results of the usage request and the usage environment information, generates instruction information indicating how to handle the license information in the relay device based on the analysis result of the usage environment information, embeds the generated instruction information in the license information, and sends the license information to the relay device. The relay device receives the license information in which the instruction information is embedded, and transfers the received license information to the SD card or the printer according to the instruction information which is embedded in the license information with performing certain processing or without performing any processing to the license information.
摘要:
A method for judging use permission of information on one or more terminal apparatuses which uses content provided by a content provider and metadata provided by a metadata provider and supplementing the content, the method comprising: metadata use permission judgment judging use permission of the metadata based on usage control information regarding use control of the metadata; and using the metadata in the case where in said metadata use permission judgment, the use of the metadata is permitted. Specifically, the usage control information includes the first signer identification information which identifies the range of the provider of the metadata that can be used. The metadata includes a signature of the metadata provider identified in the first signer identification information, and the second signer identification information identifying the signer of the signature. And, said metadata use permission judgment judges the metadata use permission based on the metadata provider identified in said first signer identification information, said second signer identification information, and signature verification.
