A gear having high pitching resistance, sufficient surface hardness, sufficient hardened depth, high abrasion resistance, high breakage resistance, high fatigue resistance, and low gear noises. A material equivalent to JIS-SCM420 is soft nitrided for two hours in a mixture gas containing 45 to 65 volume % of residual NH.sub.3 at a gas temperature of 530 to 565.degree. C., thus producing a compound layer having a hardness equal to or higher than that of the material plus Hv 50 and a thickness of 200 .mu.m or more.

To prevent the neutral state from being formed in a change gear apparatus and allow the obtaining of an intended gear change appropriately during a servo malfunction. Hydraulic servos engage and disengage a plurality of friction engagement elements; a hydraulic pressure supply system supplies the hydraulic servo of a predetermined friction engagement element with hydraulic pressure; and an auxiliary hydraulic pressure supply systems supplies a predetermined hydraulic servo with another hydraulic pressure, in the case where the hydraulic pressure supply system is placed in a first unsupplied state where the hydraulic pressure supply system cannot supply the hydraulic servo of the predetermined friction engagement element with hydraulic pressure. The auxiliary hydraulic pressure supply system does not supply the predetermined hydraulic servo with the other hydraulic pressure, in the case that the hydraulic pressure supply system is placed in a second unsupplied state where the hydraulic pressure supply system does not supply the hydraulic servo of the predetermined friction engagement element with hydraulic pressure.

Second and third clutches are axially aligned so that the back side of the second clutch and the front side of the third clutch oppose each other, and a first clutch is positioned radially inward of the second and third clutches. Further, a clutch drum is extended so as to be used in common by the second and third clutches, the second clutch is engaged and disengaged from the axial front side by a second piston of a second oil pressure actuator, and the third clutch is engaged and disengaged from the axial rear side by a third piston of a third oil pressure actuator. The first through third clutches are positioned in a compact manner and can be independently operated.

This object relates to a leather which is obtained by forming a coating film through the greasing step following re-tanning and dyeing and the drying step. The purpose of this object is to provide a leather, wherein the generation of free formaldehyde and acetaldehyde is inhibited, an automobile interior part using this leather and a back sizing agent for natural leather to be used for producing the above-described leather. A natural leather wherein a back sizing agent for natural leather containing a hydrazide compound optionally together with a resin (including an acrylic resin) is applied to the back of leather to exert an effect of fixing formaldehyde and acetaldehyde generated by a tanning agent, a re-tanning agent, a dye and a greasing agent, which have been incorporated into a leather, in the leather to thereby inhibit or prevent the generation of formaldehyde and acetaldehyde, an automobile interior part using this natural leather, and a back sizing agent for natural leather to be used for producing the above-described natural leather.

There is provided a joined product suitable as a cutting tool that is fit for high-speed cutting, CVD coating process and the like, and does not cause a reduction in joint strength of a joining layer even if a high temperature exceeding a temperature at which a brazing filler forms the liquid phase is reached during cutting. Specifically, the joined product includes a cemented carbide sintered compact serving as a first material to be joined and a cBN sintered compact or a diamond sintered compact serving as a second material to be joined. The first material to be joined and the second material to be joined are joined by a joining material that does not form a liquid phase at a temperature lower than 1000° C. and that is placed between the first material to be joined and the second material to be joined. The joining is performed by resistance heating and pressing at a pressure of 0.1 to 200 MPa.

Provided are: a double-row angular bearing capable of enhancing its rolling life and cost reduction; a bearing device for a wheel, which is capable of reducing a number of assembling process steps in an assembly factory of automobiles and the like, is excellent in productivity, and is capable of cost reduction; and a method of producing an outer race and an inner race of a bearing, which can achieve their weight reduction to a large extent. The double-row angular bearing includes: an inner race having inner rolling surfaces on a radially outer surface thereof; an outer race having outer rolling surfaces on a radially inner surface thereof; and rolling elements rotatably housed between the outer rolling surfaces of the outer race and the inner rolling surfaces of the inner race. The outer race or the inner race is formed of a plastically worked article formed by cold rolling.

The present invention relates to a method of manufacturing a sensor rotor with a minimum waste of material. The sensor rotor is manufactured by forming a plurality of ring pieces having outer and inner edges that are identical in curvature to each other, arranging the ring pieces in the shape of a ring, magnetizing the ring pieces to create opposite magnetic poles alternately in the circumferential direction of the ring pieces to form a magnetized ring, and fixing the magnetized ring to the inside of a press-in ring. Since the outer edge of each ring piece substantially coincides with the inner edge of the adjacent ring piece, it is possible to eliminate the waste of material between the adjacent ring pieces.

A wheel bearing apparatus for a driven wheel of a vehicle has an outer member, an inner member and rolling elements between the two. The outer member has a body mounting flange for mounting it to a knuckle of a suspension apparatus. The knuckle has a disc shaped bottom portion. The outer member is secured to the knuckle by fastening bolts. The body mounting flange abuts against the bottom portion of the knuckle. The inner side end of the inner member is closed by the knuckle. A plurality of pins is secured to the knuckle. Pin bores to receive the pins are formed on the body mounting flange. The pin bores radially positioning the outer member relative to the knuckle.
