Document Type and Number:
Japanese Patent JP5364105
Kind Code:
B2
Abstract:
The present invention relates to a stator (100-1000) with a profiled helical bore (106,206,306,606,706,806,906,1006) having a cast material layer (102;202;302;602;702;802;902;1002) with transducers (104A-104D;304;604A-604D;710;804;904A-904C;1010) disposed therein and describes the methods of forming such stators. Cast material can be fluidic during displacing of a transducer therein. Cast material layer 202 can include housings (218,222) disposed therein and/or a cavity 226 formed therein. Transducer can be a sensor (104A-104C) and/or an actuator 104D. Transducer 804 can extend axially along a length of the stator 800. Transducer or plurality of transducers (904A-904C) can extend along a helical path. Additionally or alternatively, sleeve 1008 can include a transducer 1010.
