    Abstract: A surface treatment method is for processing a surface of a substrate. The method includes irradiating a surface having unevenness with a laser beam satisfying all of the three following requirements: a power density in a range with a radius of 25 μm from a center of a laser beam spot is 1.0×103 to 1.0×105 kW/cm2; a power density of an entire laser beam spot is 0.08 to 0.12 times the power density in the range with the radius of 25 μm from the center of the laser beam spot; and an action time in the range with the radius of 25 μm from the center of the laser beam spot is 1.7×10-6 to 1.0×10-5 seconds. The method leaves a certain roughness on the surface of the substrate while removing fine and sharp protrusions on the surface.

    Abstract: An insulated bearing includes a pair of bearing rings arranged concentrically to each other and rolling elements arranged to be rotatable between the pair of bearing rings, at least one of the bearing rings having an insulating layer formed thereon. The one of the bearing rings having the insulating layer formed thereon has an annular groove having an arc-shaped cross section formed on each of both end surfaces of the bearing ring. At least a surface from a non-raceway surface side circumferential surface to the annular groove of the bearing ring is covered by the insulating layer. The insulating layer is a ceramic thermal sprayed layer.

    Abstract: An insulated bearing includes an outer ring, an inner ring, and a plurality of rolling elements. At least one of the outer ring and an inner ring is made of metal, the plurality of rolling elements are provided between the outer ring and the inner ring, so as to be freely rolled, and at least one of the outer ring and an inner ring is coated with an insulating layer. The insulating layer is formed of a mixture in which silicon carbide and/or aluminum nitride as an additive are/is dispersed in aluminum oxide as a base matrix. The content of the additive is 1 to 40 mass % with respect to the total amount of the mixture.

    Abstract: A piezo-electric substrate is mainly comprised of a base material and a film formed on one main surface of the base material. In the base material, the main surface on which the film is formed is a roughed main surface. The piezo-electric substrate is obtained by forming the film comprised of a material with a coefficient of linear expansion smaller than a coefficient of linear expansion of the base material on the roughened main surface using a thermal spraying method.
