A three-dimensional cam mechanism capable of selecting a cam guide surface shape freely to improve the degree of freedom for selecting a target locus on the follower side, transmitting power between orthogonal axes and performing a reversible operation. A three-dimensional cam guide surface (2 (3)) is formed in a cam (1), and the cam guide surface (2) is caused to guide a cam follower (6 (7)) formed at a predetermined angle at one end of a follower side link (4), so that the rotational movement of the cam (1) is translated into the swinging movement at the other end of the follower side link (4). Thus, smooth operations of the cam are obtained by the selection of the shape of a supporting member and by the free design of the cam guide surface shape, without being limited to the power transmission between the orthogonal axes or followed by backlash.

Abrégé
Intended is to provide a solid cam mechanism, which can select a cam guide face shape freely to improve the degree of freedom for selecting the target locus on the follower side drastically and which not only can transmit the power strongly and reliably without being limited to the power transmission between orthogonal axes but also can perform reversible actions. The solid cam mechanism is constituted such that a solid cam (1) has a three-dimensional cam guide face (2 (3)), and such that the cam guide face (2) is made to guide a cam follower (6 (7)) formed at a predetermined angle at one end of a follower link (4), so that the rotational motion of the solid cam (1) is transformed into the rocking motion of the other end of the follower link (4). As a result, the cam guide face shape can be freely selected to improve the degree of freedom for selecting the target locus on the follower side drastically, and the smooth actions of the solid cam can be obtained not only by the selection of the shape of a support member but also by the free design of the cam guide face shape while being neither limited to the power transmission between the orthogonal axes nor followed by the backlash.

Abrégé
A composite material excellent in thermal and electrical conductivity. This composite material is obtained by curing, in the presence of a magnetic field, a mixture of a liquid elastic polymeric material and a magnetic mixture fluid obtained by dispersing a nickel powder and a copper powder in a magnetic fluid. The composite material has network clusters inside which have been formed by the aggregation of copper particles and nickel particles.
