Each of the pair of holding members is movable between a receiving position in which the resin frame is received from an external supply device and a welding position in which the resin frame is welded to the edge portion of the electrode foil by the welding member, with rotation of the rotary shaft around an axis. When one of the pair of holding members is in the welding position, the other of the pair of the holding members is in the receiving position.

Abstract: An infrared heater is disposed on one side of an electrode sheet transferred along a transfer path. A radiation temperature sensor is disposed on the other side of the electrode sheet to measure the temperature of the back surface of the electrode sheet corresponding to the back side of a front surface portion of the electrode sheet that is the closest to the infrared heater. The radiation temperature sensor is configured such that the peak wavelength of infrared light radiated to the surface of the electrode sheet by the infrared heater is not included in the detectable wavelength range of infrared light detected by the radiation temperature sensor.

Abstract: The oscillation actuator of the invention uses ultrasonic vibrations generated in a stator to rotate a rotor, and a pre-load member causes a 30 MPa contact pressure between the rotor and the stator. Furthermore, a supply body impregnated with oil is provided inside a recess section in the stator, such that the contact section between the rotor and the stator is lubricated by oil supplied from the supply body. As the oil with which the supply body is impregnated, a fluorine-based oil having a kinetic viscosity at 40° C. of VG 400 according to the ISO viscosity classification is selected.

Abstract: A rotor 2 of an ultrasonic motor 1 is pressed to make contact with a pair of supporting parts 11, 12 of a stator 3. Contact surfaces 21, 22 are formed respectively following the shape of an outer circumferential surface 2b of the rotor 2, in the upper portions of the supporting parts 11, 12. Since different level sections 23, 25 are formed in the contact surface 21, and different level sections 24, 25 are also formed in the contact surface 22, the contact distance between the rotor 2 and the stator 3 is limited.
