    摘要： A system for propelling a train by a linear synchronous motor comprising a group of propelling coils disposed in pairs along a train track on the ground on opposite sides of the center line of the train track and opposite to field coils mounted on the vehicle with a predetermined gap defined therebetween, said coil pairs in the propelling coil group being connected in parallel respectively to constitute a group of short-circuited coil units which interact electro-magnetically with the field coils to stabilize the vehicle against rolling movement.

    摘要： An improved structure of a pulse transformer for simultaneously firing all the gates of a multiplicity of series-connected or series- and parallel-connected thyristors as is the case with a converter in dc transmission equipment, having a greater insulation strength and a good resistivity to external shocks. Specifically, since the converter used at high tension renders the line voltage of each thyristor higher, a molded insulating cylinder is disposed between a primary conductor and secondary conductor units of the transformer, whereby potential distributions between the secondary transformer units and the insulating cylinder and between the secondary transformer units adjacent to one another can be improved by providing conductive layers embedded in the insulating cylinder, and the pulse transformer can be made of a dry tape and small in size.
