| 20080296986 | BUSHING AND GENERATOR - In a bushing which has a terminal with a bend for connecting a conduit tube and a lead tube, the effect to cool the inner corner of the bend is enhanced. The bushing includes a conductive conduit tube, a conductive lead tube, and a terminal. The terminal has a bend and connects the conduit tube and the lead tube. Electric current and cooling gas flows in these tubes. A cooling means is provided for forced cooling of the inner corner of the bend of the terminal. One example of the cooling means is a guide vane which makes cooling gas flowing in the bushing come closer to the inner corner of the bend.

| 20090140601 | ROTARY ELECTRIC MACHINE - In a rotary electric machine, for ensuring a cooling air flow between a rotor iron core and a stator iron core without enlarging a rotor, a separation preventing device is provided at a position between adjacent slots so as to correspond to each other at a shrink-fitting position where a retaining ring is shrink-fitted to a rotor iron core. Since a separation preventing position of the retaining ring is located at the shrink-fitting position, it is possible to reduce a length of the retaining ring itself so as not to be adjacent to the end portion of the stator iron core. Accordingly, a gap between the rotor iron core and the stator iron core does not reduce. As a result, it is possible to ensure a cooling air flow between the rotor iron core and the stator iron core without enlarging the rotor. | 06-04-2009 |
