    摘要： A switch comprising a switch case, contacts adapted to be opened and closed, an arc extinguishing chamber disposed in the vicinity of the contacts, and an arc extinguishing material capable of reducing the amount of metal particles and free carbons to be scattered from components disposed within the switch by an arc generated when the contacts are opened or closed or capable of insulating the metal particles and the free carbons to convert into an insulator, thereby inhibiting a decrease in arc resistance expected to occur upon the generation and extinction of the arc and a decrease in insulation resistance expected to occur within and around the arc extinguishing chamber and at inner wall surfaces of the switch case upon and after the extinction of the arc. The switch according to the present invention is applicable to a switch expected to generate an arc upon interruption of electric current flowing therethrough such as a circuit breaker, current-limiting device or electromagnetic contactor and is capable of immediately extinguishing the arc and inhibiting the decrease in insulation resistance within and around the arc extinguishing chamber and at inner wall surfaces of the switch case.

    摘要： The present invention relates to a material strength measuring apparatus for specimens having a curved surface or an irregular surface with high accuracy. The measuring apparatus according to the present invention comprises: a supporting stand (1) for fixing a specimen (19) thereon; a guide member (3) fixed on the supporting stand so as to be vertical with respect to the supporting stand; a moving member (26) moving linearly and vertically with respect to a measured surface of the specimen along the guide member; a rotating blade (10) urged toward the measured surface of the specimen; a rotating blade supporting body (8) moving with the moving member linearly and vertically with respect to the measured surface of the specimen; a blade rotating motor (6) fixed to an end of the rotating blade supporting body; elements for forcing the rotating blade into the surface of the specimen; a torque detector (5) for detecting cutting resistance against the rotating blade; a vertical displacement detector (7) fixed to the moving member for detecting vertical displacement of the rotating blade; and a recorder (25) for recording outputs of the torque detector and the vertical displacement detector.
