Abstract: A track rod end having a head portion (12) an a stem portion (14) is initially produced as a drop forged blank such that the length of the stem portion is less than the desired length in the finished article and the diameter of the stem portion (14) is greater than the desired finished diameter. The drop forge blank is then subjected to a hydraulic forming operation which causes elongation of the stem portion (14) to the desired length and reduction of its diameter to the desired diameter. Thereafter, the head (12) may be machined to the desired configuration and the stem portion (14) may be provided with a screwthread by means of the thread rolling technique. This method reduces the amount of material required for the production of a track rod end, the extrusion step and hence the mechanical working of the stem portion (14) increases its tensile strength and the cylindrically formed stem portion (14) created by extrusion facilitates mounting of the track rod end for subsequent machining of the head (12).

Abstract: A dielectric insulator separated substrate for a semiconductor integrated circuit has a monocrystalline wafer (11) and a thick polycrystalline region formed of layers (4a-4m). Island regions (1a, 1b, 1c) are formed by machining of the wafer (11). To reduce curvature of the substrate in subsequent processing steps, there is formed a lamination of at least three thin polycrystalline leyers (4j-4m) and dielectric films (6) interposed therebetween on the thick polycrystalline region. The thickness x(µm) of each of the thin layers is     wherein y is an ultimate thickness of the substrate. With the lamination, it is possible to avoid bending deformation of the substrate due to oxygen diffusion into an exposed thick polycrystalline layer during doping of an impurity into the island regions.
