Abstract: An object is to provide a hermetic electric compressor that can simplify the installation structure of an internal protector and improve the ease-of-assembly thereof. In a hermetic electric compressor having a compressor and an electric motor (10) built into a sealed housing (2), the electric motor (10) includes a stator (8) to which plastic insulating bobbins (30) having flanges (30B, 30C) on an inner and outer circumferences of a plurality of tooth parts of a stator core are fitted and around which a stator winding wire (8A) is wound in concentrated winding around the plastic insulating bobbins (30), and an internal protector (29) for electric-motor protection is latched between the inner and outer circumferential flanges (30B, 30C) of the plastic insulating bobbins (30) by being urged against the stator winding wire (8A).

Abstract: A thermoplastic polymer composition is provided that includes 100 parts by weight of a block copolymer and/or its hydrogenate having polymer blocks of an aromatic vinyl compound and polymer blocks of a conjugated diene compound, and from 5 to 95 parts by weight of a block copolymer having polymer blocks of an aromatic vinyl compound and/or an olefinic compound and polymer blocks having a constitutional unit derived from a (meth) acrylic compound, a laminate containing a layer of the composition, and a hot-melt adhesive that includes the composition. Because it has good melt adhesiveness, the composition of the invention can firmly adhere in melt to various polar or non-polar materials. Using the composition, it is easy to produce laminates having a layer of the composition and a layer of some other material, through melt shaping or any other melt adhesion techniques.
