摘要： An electrode capable of effectively dispersing or relieving the stress generated in association with expansion and contraction of an active material is provided. The electrode is produced by forming an active material layer on a predetermined current collector. This current collector includes a base and a plurality of projections formed so as to extend outwardly from a surface of the base. The cross section of the projections in a thickness direction of the current collector has a tapered shape in which a width in a direction parallel to the surface of the base narrows from the surface of the base along an extending direction of the projections.

摘要： Provided herein is an ultrasonic motor in which at least fluorocarbon polymer is present on the contact surface of at least either of the rotor of the stator. Since the fluorocarbon polymer provides a smooth contact surface, the ultrasonic motor generates no noise and produces a stable starting torque and holding torque. In addition, it has a long life with a minimum of wear.

摘要： An electrode group is constructed by disposing a positive electrode current collector exposed portion on one end side and a negative electrode current collector exposed portion on the other end side. A positive electrode current collector terminal plate and a negative electrode current collector terminal plate are connected to the positive and negative electrode current collector exposed portions, respectively. A conductive coned disc spring is disposed compressed between the positive electrode current collector terminal plate and a sealing plate. The coned disc spring has a dead zone in which the elastic force does not change according to the amount of deformation, and urges the negative electrode current collector terminal plate toward a bottom portion of a battery case with a defined elastic force.
