    摘要: A permanent magnet alternator includes a stator core having outwardly projecting teeth and further includes a plurality of permanent magnets surrounding the stator core. The stator core is formed from a continuous, helically wound metallic strip having a plurality of teeth defined between slots formed in one edge thereof. The stator core is formed by winding the strip edgewise around a cylindrical mandrel. To facilitate winding and avoid distortion, arcuate regions, conforming to the curve of the mandrel, are formed in the strip opposite the teeth.

    摘要: An engine-driven generator includes an internal combustion engine, a permanent magnet alternator and an AC to AC converter. The output frequency and voltage of the permanent magnet alternator are largely dependent on engine speed and the alternator load. The AC to AC converter converts the speed-dependent alternating current developed by the alternator to another alternating current whose frequency and voltage are largely independent of engine speed. Voltage regulation is provided by varying the engine speed in accordance with the load current. Frequency regulation is provided by frequency dividing the alternator output by an integer divisor that varies in accordance with engine speed. Additional voltage regulation is provided by deleting selected cycles of the alternator output current as needed to maintain the RMS output voltage within predetermined limits.

    摘要: Provided are a method, system, and program for remote copying of updates to primary and secondary storage locations subject to a copy relationship. A first copy relationship is established between first and second storage locations in a first storage system and second storage system, respectively, wherein updates to the first storage locations are copied to the second storage locations. A second copy relationship is established between the first storage locations in the first copy relationship and third storage locations in a third storage system, wherein updates to the first storage locations are indicated in a first bitmap. A suspended third copy relationship is established between the second storage locations in the first copy relationship and the third storage locations, wherein updates to the second storage locations are indicated in a second bitmap. Updates are copied from the first or second storage locations to the third storage locations, wherein the first or second bitmap is capable of being used to determine updates for the first or second storage locations to copy to the third storage locations.

    摘要: Provided are a method, system, and program for maintaining consistency when mirroring data using different copy technologies. Update groups having updates to primary storage locations are formed using a first copy technology. The updates in the update groups are copied to secondary storage locations. Update groups having updates to primary storage locations are formed using a second copy technology, wherein the updates in the update groups are copied to secondary storage locations. Indication is made in a data structure of a time of an update in response to including the update in one of the update groups formed using the first copy technology. Indication is also made in the data structure of a time of the update group formed using the second copy technology.

    摘要: A method is provided for cooling an engine driven, electrical generator set and for reducing the fan noise associated with operation of the same. The method includes positioning a fan on the first side of the radiator. The temperature adjacent a first side of the radiator is monitored and the fan is rotated in response to the temperature of the air on the first side of the radiator exceeding a threshold. The fan urges air through the radiator in order to cool the engine coolant flowing therethrough.

    摘要: A gaseous-discharge lamp, in particular for motor-vehicle headlamps, includes a burner vessel made of glass or the like that contains a gas. Into this burner vessel extend two main electrodes via two gas-tight electrode bushings. Between the end regions of the main electrodes arranged in the burner vessel, an arc gap is formed, along which an electric arc develops during operation. To achieve a smallest possible ignition voltage, an arrangement is provided for producing a creepage spark gap along the inner vessel wall and/or a spark gap that is shorter than the arc gap, serving as an ignition gap that is spatially separated from the arc gap.
