Abstract: Provided is a variable magnetic flux-type permanent magnet rotary electric machine wherein a leakage magnetic flux leaking from a certain permanent magnet included in the rotor core to a permanent magnet circumferentially adjacent on either side of the certain permanent magnet is controlled by q-axis current and thereby a magnetic flux emanating from the certain permanent magnet and linking with the armature coil wound on the stator is controlled without forming a mechanically weak part in the rotor core.

Abstract: A vacuum pump including a centrifugal compressor stage on the side of a suction opening and a circumferential flow compressor on the side of an exhaust opening. The centrifugal compressor pump works as a Siegbahn pump at a steady state, and works as a centrifugal compressor under a transient condition at the initial stage of the pump operation, thus obtaining a high pumping speed under the transient condition.

Abstract: A thermal head comprising a plurality of electrode layers laminated in succession on one side of a substrate with a glass layer therebetween which serves as an electrical insulating and heat resistant layer, and a heating resistive element formed on the end surface formed by cutting an end portion of the substrate having the various layers thereon. The end surface may be subjected to skewed grinding. A method of manufacturing the thermal head is also disclosed. The thermal head is used in various types of printing machines and recorders.
