A hydro dynamic bearing device comprising an upper half of a main bearing and a lower half of the main bearing, wherein the upper half of the main bearing is lined with a low-strength metal such as a Babbitt metal, wherein a circumferential groove is formed in the lower half of the main bearing, and wherein the low-strength metal of the upper half of the main bearing, which is formed at a region opposed to a downstream side of the circumferential groove formed in the lower half of the main bearing, is partially removed to cause a high-strength bearing base metal to be partially exposed.

Hydro dynamic bearing device

In an electrical machinery and apparatus, a storage space is formed along an extension direction of a strand, and a temperature sensor is installed in the storage space of the strand, so that temperature of the strand can be immediately measured, and no pressure is applied to the temperature sensor in the process of forming a ground wall insulation thereby the temperature of the strand can be accurately measured.
