摘要： PURPOSE:To execute at each completion of a building frame of each story of a building, to avoid fray at the time of carrying in trunk ducts to the site, to average number of operators, and to facilitate maintenance and replacement of components. CONSTITUTION:The trunk device for a building comprises a connecting cable 1 passed through a lower stair floor 3, and a trunk 2 having a conductor provided with connectors at both upper and lower ends, a branch unit 11 at an intermediate part, arranged longitudinally between the floor 3 and an upper stair floor 6 and connected with an upper end of the cable 1 to the connector, wherein a lower end of the cable 1 is connected to an upper side connector of the trunk 2 already arranged at a lower position of the floor 3.

摘要： A circuit breaker utilizes an elongated contact spring member 22 which extends along the length of a breaker housing 10 in an inclined relation with respect to the longitudinal axis of the housing 10. The contact spring member 22 is fixed at its one end and carries on the other end a movable contact 23 engageable with a stationary contact 24. The contact spring member 22 is self-biased in the direction of opening the contacts 23,24 and is operatively connected to an actuator 40 which is slidably received in the housing 10 for movement between an outward and inward positions. The inward sliding movement of the actuator 40 is translated into the contact closing movement of the contact spring member 22 with the attendant deflection of the contact spring member 22 against its bias. The energy accumulated in the deflected contact spring member 22 in the closed position is liberated in response to a fault current condition to drive the actuator 40 in such a manner as to pivot the actuator 40 about a pivot axis adjacent its fixed end under the bias of the contact spring member 22. In this manner, the tripping of the contacts 23,24 can be effected by making the most of the contact spring member 22.

摘要： Arc suppressing means for current limiting circuit breakers wherein an arc generated between both movable and fixed contacts by an excess current at the time of short-circuiting is magnetically driven by a member extending from the contact part of fixed contactor to an arc running plate in the right angle relation to the plate with a shortened time of arc's staying at the contact part and a shortened time of arc's traveling from the member to a deion grid along the running plate to quickly obtain an elevated arc voltage and to thereby effectively elevate current limiting effect.

摘要： PCT No. PCT/JP83/00101 Sec. 371 Date Jun. 23, 1983 Sec. 102(e) Date Jun. 23, 1983 PCT Filed Mar. 31, 1983 PCT Pub. No. WO83/03496 PCT Pub. Date Oct. 13, 1983.A circuit breaker of the present invention provides a movable contact held by a movable contactor to be capable of passing through the interior of an arc suppressing means and to be contacted with a fixed contact from the side of the arc suppressing means. Thus, an arc generated upon an opening of the both contacts is made to shift immediately into the arc suppressing means, whereby arc dividing, cooling and suppressing are performed rapidly and the current limiting effect of the breaker is remarkably elevated.
