    Abstract: The invention provides a bearing device of a compressor for a refrigerator which can widen a clearance between a sliding surface of a bearing and a surface of a crank shaft at a time of starting, while narrowing the clearance between the sliding surface of the bearing and the surface of the crank shaft at a time of a regular operation of the compressor for the refrigerator. A thickness of a resin sliding layer is set in such a manner that a bearing clearance at a starting time becomes relatively larger than a bearing clearance at a regular operating time within a range which is equal to or more than 2.5% and is equal to or less than 20%. Accordingly, since the bearing clearance becomes larger within the range which is equal to or more than 2.5% and is equal to or less than 20% at the starting time with respect to the regular operating time, while narrowing the bearing clearance for preventing a compression efficiency of the compressor for the refrigerator from being lowered due to a deflection of an axis of a crank shaft, at the regular operating time, it is possible to prevent a sliding surface of a bearing and a surface of the crank shaft from coming into direct contact with each other.

    Abstract: A threaded joint for steel pipes comprises a pin (1) and a box (2) each having a threaded portion (3a or 3b) and an unthreaded metal-to-metal contact portion (4a or 4b) as contact surfaces which contact each other when the joint is fastened. The contact surfaces (3a and 4a and/or 3b and 4b) of at least one of the pin (1) and the box (2) are coated with a lower layer of a solid lubricating coating containing a solid lubricating powder (e.g., molybdenum disulfide, tungsten disulfide, or graphite) and a binder (e.g., an epoxy or other organic resin) and an upper layer of a solid corrosion protective coating formed by an organic resin which does not contain solid particles.

    Abstract: There is provided a method for surface treatment of a sliding portion of a product, which is an economical method, has less risk of polluting the working environment, or causing a fire by the powder dust, and yet enables high lubricativeness to be achieved, and many concavities to be formed on the sliding portion while simultaneously providing lubricativeness. Injection particles, obtained by blending soft-metal solid lubricant particles the surfaces of which have been oxidized and layered-structure solid lubricant particles, are injected onto a surface of the sliding portion of the product to be treated at an injection speed of 150 m/sec or more, thereby to diffuse and penetrate the surface to form a layer of the injection particles, and to form many concavities on the surface of the sliding portion.
