A bearing apparatus for a driving wheel of a vehicle is provided to promote reduction in the weight and size of the apparatus, suppress excessive stress or wear, and improve the durability. In a bearing apparatus for a driving wheel of a vehicle, a hub wheel(1), a constant velocity universal joint(3), and a double row rolling bearing(2) are assembled as a unit. One(1a) of the inner raceway surfaces in the double row rolling bearing is formed on the outer circumferential surface of the hub wheel, and the other(14a) of the inner raceway surfaces is formed on the outer circumferential surface of an outer joint member(14). The hub wheel and the outer joint member are fitted each other with one end surface(19) being abutted against a shoulder(16) of the outer joint member. The inner circumferential surface at the fitting portion of the hub wheel is formed with a hardened irregular portion(5). The hub wheel and the outer joint member are integrally connected via plastic deformation of the outer joint member with making the hardened irregular portion bite into the outer circumferential surface at the fitting portion of the outer joint member by radially outwardly expanding the fitting portion of the outer joint member. The outer circumferential surface of the outer joint member is formed with a hardened layer at least at a region including the inner raceway surface and a shaft portion(17) except for the fitting portion of the outer joint member.

A ceramic top coat is formed over a heat resistant alloy including Ni as a main component through a bond coat which contains Ni essentially as a main component, Cr, and Al. The alloy for the bond coat can include Si in the range from 0 to 10 wt.%. As a result, in a long time operation, the spalling damage of a ceramic top coat is not easily created and the deterioration of the mechanical properties is small.

The present invention provides a support board for perforation processing (1) having lubrication layer superimposed on at least one surface of aluminum substratum, characterized in that the lubrication layer consists of a mixed composition containing a crystalline water-soluble resin and a crystal nucleating agent. By this structuring, there can be provided a support board for perforation processing with a lubrication layer that excels in adherence to aluminum-made substratum, being free from stickiness and that excels in blocking prevention performance, ensuring easy washing after processing.

In a plasma treating apparatus, a ceramic porous substance having a three-dimensional network structure in which a frame portion formed of ceramic containing alumina is provided continuously like a three-dimensional network is used for the material of an electrode member for the plasma treating apparatus to be attached to the front surface of a gas supplying port of an electrode for plasma generation, and a gas for plasma generation is caused to pass through a hole portion formed irregularly in the three-dimensional network structure. Consequently, the distribution of the gas to be supplied is made uniform to prevent an abnormal discharge so that uniform etching having no variation can be carried out.

The present invention provides a battery package used in an assembled battery, which can miniaturize the assembled battery and can impart sufficient durability; an assembled battery which can be miniaturized and have sufficient durability by provision with the relevant battery package; and a battery device provided with the relevant assembled battery.

An antiwear chain which can be efficiently produced with excellent productivity and, despite this, has high durability even under severe use conditions as for, e.g., the timing chain of an engine. Inthe vanadium diffusion / penetration treatment of a steel base, a silicon-containing size-reducing agent is added. The vanadium carbide forming a surface-hardening layer has, in the crystal grains, a second phase comprising a silicon-containing amorphous structure. This vanadium carbide has a crystal grain diameter reduced to 1 ¢mu!m or smaller.
