摘要:
On a frictional engage surface of one of inner and outer clutch plates constructing a wet-type multi-disk clutch, a plurality of convex ridges are formed at an infinitesimal predetermined interval distance. Lubricating oil is kept between the convex ridges, so that the wedge operation in oil can be reduced, whereby the torque transfer characteristic can be improved. Further, a height of the convex ridge is set equal to or more than 1 .mu.m and the interval distance of the convex ridge is set equal to or less than 600 .mu.m, preferably.In the configuration of the clutch plate, it is made of steel as a substrate. Further, a nitrogen diffusion layer, a nitrided layer and an oxidation tunic is formed on said nitrided layer are formed on the substrate in its order therefrom.

A driving force transmission system comprising: a coupling case and a shaft arranged rotatably relative to each other; a pilot clutch and a main clutch for controlling a torque transmission between the coupling case and the shaft; an electromagnet for controlling the actions of the pilot clutch and the main clutch; and oil retaining the functions of the pilot clutch and the main clutch. This system further comprises a coupling case, a shaft, a rotor, and X-ring and an O-ring isolating a coupling oil chamber, in which the pilot clutch and the main clutch are arranged, liquid-tight from the surrounding space.

A drive force transmission apparatus includes a housing connected to one of two shafts that are rotatable relative to each other, a rotary shaft rotatably supported by the housing and connected to the other shaft, and a multiple disc clutch composed of a plurality of outer plates engaged with the housing in the rotational direction and a plurality of inner plates engaged with the rotary shaft in the rotational direction. The multiple disc clutch transmits rotational torque between the housing and the rotary shaft through frictional engagement between the outer plates and the inner plates. The apparatus also includes a pressure generation mechanism for generating a pressure corresponding to a rotational-speed difference between the housing and the rotary shaft and for applying the generated force to the multiple disc clutch via a piston. The pressure generating means is composed of a plurality of rotary blades accommodated within a cylindrical space formed between the piston and the housing and rotating together with the rotary shaft, a viscous fluid charged into a plurality of pressure chambers defined by the housing, the piston, and the rotary blades, and a free blade accommodated within at least one pressure chamber. The free blade is freely movable in the circumferential direction between the rotary blades.

Fluorescent colorant compositions contain a pigment and a resin. The pigment is a crystalline, azo-based, fluorescent pigment obtained from a coupling reaction of a specific diazo compound, which was obtained from a particular aromatic amine, with a particular acetoacetylamino-containing aromatic coupler. As crystalline characteristics of the crystalline, azo-based, fluorescent pigment, the ratio (h/w) of a height (h) of a maximum peak to its half-value width (w) in a diffraction angle (20) range of from 5 to 35° in an x-ray diffraction spectrum of the pigment may preferably be 20 or greater. Also disclosed are coloring processes and colored articles, which make use of the fluorescent colorant compositions.

A graft copolymer is formed by copolymerization of (A) a macromonomer and (B) a monomer. The macromonomer (A) is a polymer of (a) an ester monomer between an addition-polymerizable, unsaturated carboxylic acid and an aliphatic alcohol and (b) an addition-polymerizable monomer having an acidic group. The polymer contains an addition-polymerizable group at an end thereof, and has an acid value of from 100 to 300. The monomer (B) is an addition-polymerizable monomer. Units of the macromonomer (A) amount to from 20 to 50 wt. % of the whole graft copolymer, and units of the monomer (B) amount to from 50 to 80 wt. % of the whole graft copolymer.
摘要:
A friction clutch includes an iron inner clutch plate and two iron outer clutch plates. Each clutch plate has a sliding surface that friction-engages with the other clutch plates. A diamond-like carbon film containing silicon, which functions as a solid lubricant, is formed on the sliding surface of each outer clutch plate through a conventional method such as plasma chemical vapor deposition. The diamond-like carbon film contains 1 wt % to 80 wt % of silicon. A coupling device includes a pilot clutch mechanism that has the friction clutch and an electromagnetic actuator. As a result, the friction clutch has an improved resistance to wear, and the coupling device is durable.
