A driving gear of a vehicle comprising a motor generator (MG2), a power control unit (21) for controlling the motor generator (MG2), and a case for containing the motor generator (MG2) and the power control unit (21). The power control unit (21) comprises a first inverter for driving the motor generator (MG2), and a voltage converter for applying power supply voltage to the first inverter after stepping it up. The voltage converter includes a reactor (L1). Heat of the reactor (L1) is dissipated using lubricant touching the reactor (L1) and the case as heat transfer agent. A circulation path of lubricant is formed in the case and the reactor is arranged on the circulation path.

The thermal printer of the present invention is a thermal printer for printing on a print medium by thermally transferring an ink ribbon by means of a thermal head, wherein the thermal printer comprises a density controller for keeping the print density of the thermal head low in low-temperature control for raising the print density at low temperatures. The density controller comprises a density calculator for calculating a density evaluation value by finding an average gradation value of print data for each of a plurality of dots included in the predetermined region, a comparator for comparing the calculated density evaluation value with a predetermined value, and an adjuster for adjusting, on the basis of this comparison result, the print density in driving and printing with the thermal head to a low value for print data of high gradation exceeding a predetermined gradation value in print data on a printed line when the density evaluation value exceeds a predetermined value. The printing of each dot by the thermal head is controlled on the basis of the adjusted print density. Even if low temperature control is carried out by the thermal head when the ambient temperature is low, the occurrence of ink ribbon wrinkling due to the effect of print density is suppressed.

A method and an apparatus are provided for handling a list DMA command in a computer system. The list DMA command relates to an effective address (EA) of a system memory. At least one processor in the system has a local storage. The list DMA command is queued in a DMA queue (DMAQ). A list element is fetched from the local storage to the DMAQ. The list DMA command is read from the DMAQ. A bus request is issued for the list element. If the bus request is a last request, it is determined whether a current list element is a last list element. If the current list element is not the last list element, it is determined whether the current list element is fenced. If the current list element is not fenced, a next list element is fetched regardless of whether all outstanding requests are completed.

A computer architecture and programming model for high speed processing over broadband networks are provided. The architecture employs a consistent modular structure, a common computing module and uniform software cells. The common computing module includes a control processor, a plurality of processing units, a plurality of local memories from which the processing units process programs, a direct memory access controller and a shared main memory. A synchronized system and method for the coordinated reading and writing of data to and from the shared main memory by the processing units also are provided. A hardware sandbox structure is provided for security against the corruption of data among the programs being processed by the processing units. The uniform software cells contain both data and applications and are structured for processing by any of the processors of the network. Each software cell is uniquely identified on the network. A system and method for creating a dedicated pipeline for processing streaming data also are provided.
