Dual-type tunneling magnetoresistance elements and associated methods of fabrication are disclosed that allow for higher bias voltages. The negative front lens group includes at least three negative meniscus lens elements each of which has the convex surface facing toward the object; and the three negative meniscus lens elements satisfy the following conditions:0. Measurements of the three phase voltages are received from one line terminal. The means of fulfilling this object is a polyester resin comprising a major part of ethylene terephthalate units and containing at least one of minor copolymerizable components selected from a group consisting of isophthalic acid, cyclohexane dimethanol, and diethylene glycol, wherein three minor copolymerizable components have total content less than 3 mol.
