Abstract: The emergency stop switch 2 performs an operation support of an operation switch, and not only improves operability and safety but also simplifies the structure to enhance reliability. The emergency stop switch (or operation switch unit) 2 with an operation support function includes an emergency stop button (or operation switch) 21 for switching the state of the contact, a reception part (or detection part) 32 for detecting a remote operation of the emergency stop button 21 and an electromagnetic solenoid (or actuating part) 3 that is disposed between the contact and the emergency stop button 21 and that actuates the emergency stop button 21 on the basis of the remote operation received (or detected) by the reception part 32. The emergency stop button 21 is located on one end side of the emergency stop switch 2 and the contact is located on the other end side of the emergency stop switch 2.

Abstract: The present invention relates to an feed additive comprising a Licorice extract for improving the quality of embryos obtained after the superovulation treatment, as well as, a method for improving the quality of the embryos obtained after the superovulation treatment comprising rearing to a mammal with superovulation treatment using a feed added with Licorice extract.

Abstract: This invention relates to a method or apparatus by which comparatively low-voltage electric wires and cables laid at power stations and other locations can be diagnosed for deterioration of their polymer-insulation in a non-destructive way. The method or apparatus comprises applying a torsional force to the electric wire or cable, detecting the resulting repulsion as a torque, and estimating the degree of deterioration of the polymer-insulation in the electric wire or cable on the basis of the detected value of torque.
