摘要:
A guide tube formed of a non-magnetically permeable material is coaxially disposed in a brake drum coupled to a rotational shaft and a magnet support tube formed of a non-magnetically permeable material is axially movably supported within the guide tube. A plurality of magnets are supported at equal annular intervals on the outer wall of the magnet support tube and proximal surfaces of ferromagnetic members are coupled to magnetic pole surfaces at opposite ends of the magnet. Actuators reciprocate the magnet support tube between a braking position in which extreme end surfaces of the ferromagnetic members are opposed to an inner surface of the brake drum and a non-braking position in which the ferromagnetic members are withdrawn from the brake drum.

A metal-containing composition contains an organic acid group, a transition metal, an alcohol amine, and water. The alcohol amine is preferably expressed by chemical formula (1):NH.sub.m R1.sub.n (R2OH).sub.3-m-n (1)where R1 is an alkyl group having 1 to 4 carbon atoms, R2 is an alkyl carbon chain having 1 to 4 carbon atoms and m and n are integers of 0 to 2 that satisfy the relationship of (m+n)
摘要:
Magnets (20) are separated by ferromagnetic plates (21) from an inner surface of a brake drum (13) made of steel and secured to a rotational shaft (4). When the rotating brake drum (13) crosses magnetic flux generated by the magnets (20), a braking force caused by eddy currents is produced in the brake drum (13). An annular body (41) formed of a good conductor such as copper is fastened adjacent to at least one side surface of the brake drum (13) in a position axially spaced from the plates (21).
摘要:
A socket for an electrical part to prevent a bad electrical connection with a circuit by preventing a deformation of a tip of a contact pin. The contact pin of the present invention comprises one terminal contacts to a terminal of the electrical part and the other terminal contacts to the circuit. When a tip of the other terminal is pressed to a substrate under a state that first and second holes of first and second holding plates are shifted each other, an upper terminal of the held portion of the other terminal contacts to a lower surface of the second holding plate, and makes the second holding plate to separate from the first holding plate against a spring force of a urging member. At this time, the portion projecting from the lower surface of the first holding plate toward the substrate moves into the first hole.

摘要:
A transmission apparatus includes at least an auxiliary transmission for supplementing a main transmission. The auxiliary transmission includes a damper which has a damper characteristic adapted to a low speed select state of the auxiliary transmission, and which is disposed in a low speed transmission path used for transmission of torque in the low speed select state of the auxiliary transmission. The auxiliary transmission further comprises a bypass member defining a bypass transmission path bypassing the low speed damper. The bypass transmission path is a torque path used for transmission of torque in a high speed select state of the auxiliary transmission.
