    摘要: There are provided a lubricating oil composition for a fluid dynamic bearing, and a HDD motor fabricated using the same. The lubricating oil composition includes an ester base oil and 0.01 to 3.00 parts by weight of an additive relative to 100 parts by weight of the base oil and has a density of 0.900 g/cm3 or less at 15° C. and a kinetic viscosity of 9.50 cSt or less at 40° C. According to the present invention, the HDD motor is fabricated by using a lubricating oil composition for a fluid dynamic bearing, the lubricating oil composition having advantages such as low viscosity at practical temperature, reduced evaporation loss and enhanced oxidation stability, thereby improving impact resistance and low temperature operational stability of a fluid dynamic motor.

    摘要: A spacer grid used for placing and supporting fuel rods in nuclear reactor fuel assemblies is disclosed. The spacer grid of this invention has a plurality of grid springs designed to have an optimal shape of their vertical support parts, thus reducing fretting wear of the fuel rods caused by contact of the fuel rods with the grid springs. The grid spring has a vertical support part and a fuel rod support part. The vertical support part includes upper and lower base parts extending downward and upward from the central portions of the top and bottom edges of an opening formed at the central portion of a unit strip, and two bridge parts branched from the upper base part and extending symmetrically downward until they are united at the lower base part. The fuel rod support part includes a conformal support part brought into surface contact with the external surface of a fuel rod. Two transverse connection parts extend outward from the opposite outside edges of the conformal support part while being specifically bent, and are integrated with the central portions of the inside edges of the two bridge parts into a single structure, thus connecting the fuel rod support part to the vertical support part.

    摘要: A fuse of a semiconductor device includes first fuse metals formed over an underlying structure and a second fuse metal formed between the first fuse metals. Accordingly, upon blowing, the fuse metals are not migrated under conditions, such as specific temperature and specific humidity. Thus, reliability of a semiconductor device can be improved.
