摘要： A V-ribbed belt that includes a ribbed surface covered with fabric is provided. The fabric is stretchable in two predetermined directions. A method for manufacturing the V-ribbed belt is also provided. The method includes placing a belt matrix about a mandrel, placing a fabric about the external circumference of the belt matrix which wraps around the mandrel, placing the mandrel inside a shell having a plurality of grooves on the internal circumference, expanding the belt matrix and the fabric toward the internal circumference of the shell and thus pressing the fabric onto the internal circumference having the multi-ribbed structure, and curing the belt matrix with the fabric. The fabric is stretchable to accommodate itself to the multi-ribbed structure.

摘要： A heat engine includes a first rotatable pulley and a second rotatable pulley spaced from the first rotatable pulley. A shape memory alloy (SMA) element is disposed about respective portions of the pulleys at an SMA pulley ratio. The SMA element includes a first wire, a second wire, and a matrix joining the first wire and the second wire. The first wire and the second wire are in contact with the pulleys, but the matrix is not in contact with the pulleys. A timing cable is disposed about respective portions of the pulleys at a timing pulley ratio, which is different than the SMA pulley ratio. The SMA element converts a thermal energy gradient between the hot region and the cold region into mechanical energy.

摘要： A control device of a continuously variable transmission for a vehicle has a pair of variable pulleys and a transmission belt, and the control device respectively controls input-side and output-side thrust forces of input-side and output-side variable pulleys to set an actual gear ratio to a target gear ratio, prevents a slip of the transmission belt, and determines a lowest-speed-side gear ratio. When it is determined that a detection value of a rotation speed for calculating the actual gear ratio does not reflect an actual rotation speed, target input-side and output-side thrust forces are set to be target thrust forces for maintaining the lowest-speed-side gear ratio and preventing the slip of the transmission belt, and based on whether the actual gear ratio is already the lowest-speed-side gear ratio, values of the input-side and output-side thrust forces are changed for obtaining the target thrust forces.
