Abstract: A partition wall member includes a main body portion and a plurality of protrusions. The plurality of protrusions protrude from the main body portion toward at least one battery cell of the plurality of battery cells. Each of the plurality of protrusions has a first end portion, a second end portion, and an intermediate portion. The first end portion and the second end portion face each other in a second direction orthogonal to the first direction. The intermediate portion is located between the first end portion and the second end portion. A cooling medium path along the second direction is formed between the plurality of protrusions. When viewed in the second direction, a cross sectional area of the cooling medium path is decreased from the first end portion toward the intermediate portion and is increased from the intermediate portion toward the second end portion.

Abstract: A plurality of battery cells are arranged side by side in a first direction and each have a prismatic shape. A case accommodates the plurality of battery cells, and supports the plurality of battery cells in at least a first direction, and forms a unit including the plurality of battery cells. The case includes a first end portion and a second end portion arranged side by side and facing each other in a second direction orthogonal to the first direction. The first end portion is provided with a biasing portion that is deformed, when one battery cell of the plurality of battery cells is inserted into the case, to bias the battery cell toward the second end portion of the case. The second end portion is provided with a reference surface to position the battery cell in the second direction.

Abstract: A content playback system for sharing content possessed by many users who each hold a token of encrypted content, the content playback system including a playback requesting apparatus which holds a token and which requests the playback of the encrypted content, and a temporary playback apparatus for performing the playback of the encrypted content in response to a playback request of the content. The temporary playback apparatus transmits a token sending request in a form in which an identifier of the content and a digital signature are attached. The playback requesting apparatus returns the token to the temporary playback apparatus only when an authentication procedure for the digital signature is successful.

Abstract: In order to maintain consistency between an instruction cache and a data cache and between the caches and a main memory, there is provided a cache memory system having a processor, a main memory, and a cache memory disposed between the processor and the main memory, which comprises an instruction cache for holding an instruction and a data cache for holding data, which comprises transferring means for transferring data directly from the data cache to the instruction cache; with which it is possible to exclude a time consuming processing such as access to the main memory, execution of a special instruction or the like.

Abstract: In order to share content possessed by each user among a plurality of users who hold a token of encrypted content, a content playback system includes a playback requesting apparatus which holds a token and which requests the playback of the encrypted content, and a temporary playback apparatus for performing the playback of the encrypted content in response to a playback request of the content. The temporary playback apparatus transmits a token sending request in a form in which an identifier of the content and a digital signature are attached. The playback requesting apparatus sends back the token to the temporary playback apparatus only when the authentication procedure for a digital signature is successful.

Abstract: The size of the address space to be occupied by an expanded board installed into a slot is identified, and the corresponding relationship between an address of a computer and a slot selection signal for selecting any one of the slots is set in a mapping table on the basis of the identification result, whereby the address space to be occupied by the expanded board is adaptably allocated on an address space of the computer.
