Each of the coils provided in a stator includes a wire introducing portion where a wire is introduced into a groove, an adjusting portion including the wire wound within the groove, and a plurality of wire layers each of which are aligned adjacent one another along an extending direction of a tooth. Among the plurality of wire layers, wires located on a periphery side-end in the odd-numbered wire layers are separated from an inner circumferential surface of the periphery by a half pitch.

Stator and brushless motor

One aspect of the present teachings includes a separation membrane arranged in a hollow case. A particular component concentration chamber and a particular component dilution chamber are arranged in series in the hollow case. The particular component concentration chamber is capable of increasing concentration of the particular component by allowing permeation of the particular gas through the separation membrane. The particular component dilution chamber is capable of increasing concentration of the particular component by not allowing permeation of the particular gas through the separation membrane. The particular component concentration chamber and the particular component dilution chamber are configured such that only a gas containing the particular component and permeated through the separation membrane or only a gas containing the particular component not permeated through the separation membrane in one of the chambers disposed on an upstream side (i.e., the side of the inlet port) can flow into the other of the chambers.

Separation membrane module and fuel vapor processing apparatus incorporating the same

A separation membrane module for separating a specific component from a mixture containing a plurality of components includes a plurality of separation stages each including a plurality of hollow fiber membranes arranged in parallel to each other. The separation stages are connected in series via connection portions allowing passage of the mixture. At lease one parameter relating to separation by the hollow fiber membrane or membranes in each separation stage is determined to provide effective separation throughout the separation stages.
