  • Publication number: 20100181326
    Abstract: An object of the present invention is to provide an oil tank structure capable of cooling oil flowing into the oil tank to properly adjust the oil temperature, and also capable of preventing overcooling. The oil tank structure includes a tank portion; an oil introducing portion that is provided in a sidewall of the tank portion and introduces oil in a direction tangential to the sidewall; at least one groove-like passage portion that is formed along a circumference of the sidewall so to allow the introduced oil to flow in and out; an oil cooling portion that is provided on the sidewall and cools the groove-like passage portion; and an outlet formed in a bottom of the tank portion. By such an oil tank structure, oil having a high temperature easily flows into the groove-like passage portion due to its low viscosity, and is cooled by the oil cooling portion.

  • Patent number: 7727407
    Abstract: There are provided a method of processing an amorphous material which is capable of forming surface projections of uniform height in desired positions on the amorphous material, and a magnetic disk substrate using the amorphous material. A predetermined pressure is applied to selected parts of a surface of an amorphous material using fine particles having a hardness higher than that of the amorphous material to form high-density compressed layers, and a surface layer of the amorphous material is removed using a treatment agent that has a different removal capacity in the compressed layers and a remaining uncompressed layer, thus making the compressed layers project out. For example, the treatment agent may be an etching solution having a different etching rate in the compressed layers and the uncompressed layer.
