摘要： An operating device for a gas circuit breaker includes an operating piston reciprocably movable between a first position and a second position, with the operating piston dividing an internal space of the operating cylinder into a first chamber and a second chamber. An exhaust port in the operating cylinder communicates with the first chamber when the operating piston is disposed near the second position, and the exhaust port communicates with the second chamber when the operating piston is remote from the second position. High-pressure air is introduced into the first chamber at the time of the breaking operation. An exhaust valve device discharges the air from the first chamber when the air pressure within the first chamber decreases below a predetermined level. The exhaust valve device includes a valve element having a pressure-receiving portion receiving the air pressure from the first chamber. The pressure-receiving portion is positioned so as to be out of contact with the operating piston when the operating piston is disposed at the first position.

摘要： A gas-filled circuit breaker includes a hermetically sealed tank formed by a surrounding wall filled with an insulating gas, at least one pair of contacts which are arranged in the inside of the surrounding wall, and a contact operating device for connecting the contacts to each other for conducting electricity therebetween and separating the contacts from each other for interrupting the electricity therebetween. The contact operating device includes a force generating device for generating a force for operating the contacts, and the contact operating device is arranged outside of the surrounding wall. A rotational shaft device is connected to the force generating device outside of the surrounding wall and extends from the outside of the surrounding wall to the inside thereof so that the force generated by the force generating device is transmitted through the surrounding wall to the inside thereof. A seal device is arranged between the surrounding wall and the rotational shaft device to maintain a hermetic seal therebetween, and at least two bearings rotatably support the rotational shaft device; and a connecting device for transmitting the force from the rotational shaft device to at least one of the contacts is moved in relation to another one of the contacts, wherein the connecting device is connected to the rotational shaft device between the bearings.

摘要： To simply and accurately determine the position of an edge, the depth or the height of a flaw including a surface crack, a corroded portion near the surface layer of a thick specimen, and a minute damage.An ultrasonic flaw detection method causes an ultrasonic wave 16 to be incident on a specimen 6 from an oblique direction, detects a diffracted wave 17 generated at an edge of a flaw 20 in the specimen 6 above the flaw, and determines the position of the edge of the flaw 20 from a front surface 13 of the specimen 6 using a triangular method from an entire beam path Wt of a component 18, which directly propagates above the flaw 20, of the diffracted wave, the entire beam path passing through the flaw from the position of incidence of the component 18, and an interval S between the position of incidence and the position of detection of the ultrasonic wave or from the difference (tt−ts) between the propagation time of a surface wave 15, to which the above relations reflect, to reception and the propagation time of the diffracted wave 18, which directly propagates above the flaw, to reception.
