IPC: G06F13/362
Filed: 2002-10-17
Abstract: <P>PROBLEM TO BE SOLVED: To prevent an internal system bus from being locked due to I/O operation delay.  <P>SOLUTION: A CPU 11 and DMA controller 12 included in an LSI circuit 10 are able to perform access to either an SDRAM 30 or an input/output device 40 connected through a shared external bus 20. A shared external interface 17 carries out arbitration to access to an external bus between the memory controller 14 and the I/O controller 15. The DMA controller and CPU which has acquired the bus master right of the internal system bus 13 hand over the bus master right to the CPU and DMA controller which claim the bus mater right when the memory controller or I/O controller are not able to perform access to the SDRAM and input/output device. Then, when the memory controller and I/O controller are turned to be able to perform access to the SDRAM and input/output device, the the DMA controller and CPU preferentially acquires the bus master right.  <P>COPYRIGHT: (C)2004,JPO

IPC: H01F38/12
Filed: 2002-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a reliable ignition coil by preventing insulation breakdown between the high-voltage side and the low-voltage side. SOLUTION: A dummy coil 513 is wound between collar sections 510b and 510c formed on the terminal plate 34 side of a secondary spool 10, and electrically connects a secondary coil 512 and the terminal plate 34. The dummy coil 513 has a cylindrical outer shape, and so an area of the dummy coil 513 as a whole which is opposite to the low-voltage side of the ignition coil 2 is large. Because an electric field is weak near the dummy coil 513 applied with high voltage, no trees of epoxy resin 29 are generated between the dummy coil 513 and the low-voltage side. Consequently, the dummy coil 513 an the low-voltage side can be kept sufficiently insulated from each other, resulting in retaining the reliability of the ignition coil 2.
