Abstract: Disclosed is a litz wire coil that is configured by spirally winding a litz wire on one plane by a predetermined number of turns. The litz wire is configured by twisting together a plurality of enameled wires formed by baking an insulating film on a conducting body. Pressure shaping is performed such that the litz wire has a substantially rectangular shape in cross section, and the flatness ratio of the litz wire in cross section (long side/short side) is controlled at 1.10 to 1.60, preferably 1.20 to 1.40, more preferably 1.25 to 1.35.

Abstract: A terminal connecting method including: removing a insulation film by a predetermined length from one end of a litz wire; inserting to a pressure fixing part a terminal part of the litz wire; compressing a first portion of the pressure fixing part with a first compression force to cause plastic deformation of an entirety of the pressure fixing part, and to temporarily fix the terminal part of the litz wire to the pressure fixing part; compressing a second portion of the pressure fixing part with a second compression force greater than the first compression force to locally cause plastic deformation of the pressure fixing part and the litz wire, the second portion being a part of the first portion; and pouring molten solder from a front end side of the pressure fixing part to firmly fix the litz wire to the terminal metal fitting.

Abstract: A method of manufacturing a heat-fixing rubber roller includes: forming a rubber layer of a silicone rubber composition on an outer periphery of a metal core shaft, the composition containing water-soluble sugar powder and methylene glycol; vulcanizing the rubber layer; and eluting the sugar powder and the triethylene glycol from the vulcanized rubber layer to form a foam rubber layer.
