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.

The contamination pouch includes an inlet facing into a body part of the differential case and capable of collecting a contamination in an oil inside the body part. In an inner surface of the differential case, the inlet is arranged in a largest inner diameter part on which a largest centrifugal force acts during rotation of the differential case, or arranged closer to an oil discharging port with respect to the largest inner diameter part in an axial direction.

Abstract: Provided is a transmission device including a differential case. The differential case is configured to be divided into first and second cases defining therebetween a mechanism chamber housing a differential mechanism therein and capable of storing an oil at a bottom part of the mechanism chamber. Two or more planetary gears are pivotally supported by a carrier of a gear reducer in the vicinity of large-diameter gear parts and pivotally supported by the differential case in the vicinity of small-diameter gear parts. The second case is held between the first case and the carrier coupled to the first case, whereby the second case is fixed to the first case.

Abstract: An electrode assembly is an electrode assembly of a lithium ion secondary battery in which sheet-like positive electrodes and sheet-like negative electrodes are alternately stacked, with bag-like separators interposed therebetween. The area of the first main surface of each of the positive electrodes is smaller than the area of the first main surface of each of the negative electrodes, and the area of the second main surface of each of the positive electrodes is smaller than the area of the second main surface of each of the negative electrodes. The first main surfaces of the positive electrodes and the negative electrodes are opposed to each other, with the respective bag-like separators interposed therebetween, and the second main surfaces of the positive electrodes and the negative electrodes are opposed to each other, with the respective bag-like separators interposed therebetween.

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.
