Abstract: Notch bottom parts 152a, 152b are arranged side-by-side with terminal accommodation boxes 100a, 100b in a circumferential direction of an insulator 134, and a routing direction of a pair of coil ends 44a inside the terminal accommodation boxes 100a, 100b is directed to a direction intersecting with an insertion direction of flat-type male terminals T1, T2.

Abstract: A self-healing vacuum insulation panel and a method of manufacture are provided. The vacuum insulation panel includes a self-healing, multi-layer barrier film including a separator between a curing agent and a curable resin.
