Abstract: An overcurrent protective wire wound resistor has a core, a second contact cap and a resistance wire. A first contact cap and a resistor connection seat are respectively mounted on two ends of a rod of the core. A low melting-point conductive layer is mounted around the rod and connected with the first contact cap and the resistor connection seat. A high-temperature contractive insulation layer is mounted around the low melting-point conductive layer and the first contact cap. The second contact cap is mounted around the contractive insulation layer. The resistance wire is connected to the resistor connection seat and the second contact cap. When current through the resistance wire abnormally increases, high temperature of the resistance wire melts the low melting point conductive layer to shrink the contractive insulation layer and open the low melting-point conductive layer and the resistor, thereby protecting the circuit connected to the resistor.

Abstract: In a robot for training a rehabilitator, the driving of actuators is controlled to generate the forces acting in six directions at the distal end of a bi-articular arm device to reproduce the relationship between the muscular output of the upper or lower limb of the human body and the output direction at the distal end of the limb. The rehabilitator can experience the relationship between the outputs of his or her limb muscles and the output direction at the distal end of the limb. Thus, the six actuators are run in operation along a predetermined sequence. One or more of the actuators, selected so that the direction of the force generated at the distal end of the first link will be the selected direction, is run in operation. The rehabilitator holding the distal end of the first link may physically experience the direction of that force.
