Abstract: An overlapping portion of an insulating portion formed in an annular shape is held between a workbench having a linear projection and an ultrasonic horn having a circular projection with at least part of the linear projection and of the circular projection opposed to each other and ultrasonically welded. In the ultrasonic welding, even though the ultrasonic horn under ultrasonic vibration rotates on the overlapping portion of the insulating portion, the area in the overlapping portion held between the linear projection and the circular projection with at least part of the linear projection and of the circular projection opposed to each other is not reduced after ultrasonic vibration is applied to the ultrasonic horn.

Abstract: Annular portions of a first interphase insulting sheet have void portions. After a U-phase coil is inserted in wave winding, bridge portions are mounted to slots for an adjacent V-phase coil. The void portions are formed at positions corresponding to the bridge portions that are disposed between any two of coil ends. The annular portions are stretched to form a generally pentagon shape, which facilitates mounting of the V-phase coil. The void portions formed at positions that do not need insulation will not impair the insulating function of the first interphase insulating sheet. The void portions formed in alignment with extension of the bridge portions will not cause a drop in the strength of the annular portions.

Abstract: DPN is an intractable and tormenting neurovascular and dermal disorder. Two patients of DPN of stocking-glove pattern were treated with SAG for treatment of microvascuar coagulopathy, induction of vasodilation and possible induction of angioneogenesis; with ALC for ATP generation through mitochondrial beta-oxidation of fats; and with ALA for antioxidative stress to prevent precipitation of vascular damage and to prevent DPN recurrence. SAG+ALC was to cure maceration. Thus, SAG+ALC+ALA was effective in mitigating and curing their distresses. It shall be one of the logical and practical means of prompt DPN therapy not only to alleviate DPN but also to lead to “cure.
