    摘要: A motor-driven X-type resistance spot welding gun. A servo-controlled motor torque is converted into force to drive gun arms and into electrode force by using a reduction gear without converting rotational output of the motor into rectilinear motion. The two arms are respectively attached to an output shaft of the reduction gear or a case, and the rotational output of the motor can be converted into swing-wise movement to close and open the arms. The electrode tips on the arms nip a workpiece to apply electrode force to the workpiece, and current is passed through the workpiece to perform spot welding. A motor, a reduction gear and the like are assembled on a common base to form a driving unit so that an arm actuator for the X-type resistance spot welding gun is formed. The same driving unit can be used commonly to various X-type gun models. The independent properties of functions of a bracket for attaching the welding gun to a robot are improved. Since properties of the arm actuator and the bracket are not dependent on a welding unit of the gun (portion through which welding current flows), the production cost for a manufacturer and maintenance cost for a user are reduced.

    摘要: An optical modulation method and apparatus uses superconductive oxide material for the optical modulation element. The current, magnetic field, temperature or pressure applied to the superconductive oxide material is varied so as to induce a superconduction-normalconduction transition, and the resulting variation in optical characteristics such as the reflectivity, transmissivity or refractive index of the superconductive oxide material modulate the input light. The method and apparatus are fast in operation and simple in structure. The method and apparatus also detect the variation in the current, magnetic field, temperature or pressure as a change in the reflectivity, transmissivity or refractive index of the superconductive oxide material on the basis of a superconduction-normalconduction transition.
