Abstract: A bus system includes a bus module which performs data transfer between a master module and a slave module and a detection module which detects transfer of transmission data from the master module to the bus module. When the bus module is shifted to a power saving mode and then is returned from the power saving mode, a power control module delays release of the power saving mode until a plurality of data transfer requests is detected. Accordingly, a power saving effect can be improved in the bus system.

Abstract: A data transferring apparatus includes a receiving unit configured to receive a transfer request containing attribute information that indicates a type of data transfer, a buffer configured to store the transfer requests received by the receiving unit, a storing unit configured to associate the attribute information with a first identifier and store the attribute information, and a sending unit configured to preferentially transmit, out of the plurality of transfer requests stored in the buffer, a transfer request containing attribute information that corresponds to the attribute information stored in the storing unit, wherein the sending unit is configured to transmit the first identifier associated with the attribute information that corresponds to the attribute information contained in the transfer request in place of the attribute information of the transfer request.

Abstract: Transfer efficiency of data transfer in a single semiconductor device or between semiconductor devices is improved. A table is created by associating a combination of attribute information involved in data transfer with an identifier. When attribute information registered in the table is received, the attribute information is replaced with an identifier so that the information is compressed and transferred. Accordingly, transfer efficiency is increased in transmission or reception of a request and a response.

Abstract: A camshaft having a steel shaft and cam pieces made from a sintering iron-base alloy material and fixed to the shaft by sintering. Prior to sintering, the green or pre-sintered cam piece is fitted on the shaft and positioned by a steel positioning pin, which is inserted both into a pin-receiving hole in the shaft and into a pin-receiving groove on the side surface of the cam piece. The positioning pin contains carbon less than the steel shaft. This results in that the carbon diffusion initiates at a predetermined position where the pin and the cam piece are in contact with each other and that the cam piece always shrinks about the position.
