    • A working method for a sapphire substrate for dividing a sapphire substrate along a set planned dividing line includes a cutting groove forming step of positioning a cutting blade, which includes a cutting edge to which diamond grain is secured by nickel plating, to a planned dividing line of the sapphire substrate and feeding the cutting blade and the sapphire substrate relative to each other for working while rotating the cutting blade to form a cutting groove, which serves as a start point of break, along the planned division line on the sapphire substrate, and a breaking step of applying external force to the sapphire substrate, for which the cutting groove forming step is carried out, to break the sapphire substrate along the planned dividing line along which the cutting groove is formed. The cutting groove forming step is set such that a rotational speed of the cutting blade is 20000 to 35000 rpm, a cutting-in depth of the cutting blade is 5 to 15 μm and a working feeding speed is 50 to 150 mm/second.

    • An ultrasonic motor includes rotors and an annular stator, which are integrated in the rotational direction, a rectangular parallelepiped multilayer piezoelectric transducer, a support shaft, and a transducer with drivers. The support shaft is attached to the outer circumference of the stator and arranged along the radial direction, and the drivers are abutted by a spring urging force to the rotors arranged on both sides of the stator in the axial direction, and are clamped with the rotors. When the transducer is driven so as to excite an elliptical movement produced by combining a bending standing-wave vibration with a longitudinal vibration with the drivers, the rotors are rotated relatively to the stator. Since the drivers are clamped with the integrated rotors, the ultrasonic motor can be driven with small frictional loss and improved conversion efficiency.
