    摘要: A method to form a field winding for a slotless stator including: forming the first coil group by spirally winding an insulated wire for each coil winding around a mandrel such that each turn of the wire is adjacent a next turn of the wire; after forming the first coil group, axially shifting along the mandrel the insulated wire from a trailing edge of each coil winding to position the wires at a leading edge of each of coil winding in the second coil group; forming the second coil group by spirally winding the insulated wire for each coil winding around a mandrel; removing the mandrel from the wound first and second coil groups; collapsing the wound coil groups to a layer web such that coil winding segments are interleaved; and wrapping the web into a cylinder to form the field winding.

    摘要: There are disclosed a composition for protective coating material, preferably for a protective coating material of a semiconductor device which is constituted of principal elements of a semiconductor memory element, an encapsulating layer containing an inorganic material for encapsulating said element and a layer of a cured protective coating material arranged between said memory element and said encapsulating layer, which is composed of a polyamide acid obtained by the reaction of a diaminosiloxane, an organic diamine containing no silicon and an organic tetrabasic acid dianhydride, and a semiconductor device having a layer of a cured protective coating material composed of a polyimide-silicone copolymer obtained by dehydrating ring closure of the above-mentioned polyamide acid.
