Abstract: A PCI bridge circuit connects to first and second PCI buses and performs data transfer between PCI devices. The PCI bridge circuit has a data buffer and controller and the controller 70, prior to the establishment of a data transfer state with the first PCI device via the first PCI bus, receives data from the second PCI device via the second PCI bus into a data buffer and inserts a wait state. Consequently while reducing the capacity of the data buffer, data transfer between PCI devices can be performed without affecting the transfer performance.

Abstract: Wedge guides 12 for holding a wedge 11 are mounted onto a base 10, and a stripper 15 is fixed to the other end of the wedge guide 12. A blade holder 13 including a plurality of blades 16 vertically installed is held in such a manner as to be freely advanceable and retractable in an up-and-down direction. A coil 30 wound is inserted between the blades 16, and alignment tool 7 is inserted at the tip ends of the blades. A stator iron core 40 is inserted into the alignment tool 7, and the stator iron core 40 is moved until the tip ends of the blades 16 penetrate the stator iron core 40. Thereafter, the stator iron core 40 and a connecting rod 19, the other end of which being connected to the blade holder 13, are pushed by a stator pusher 50, whereby the blade holder 13 is also caused to move together with the stator iron core 40 to insert the coil 30 into grooves in the stator iron core 40.
