摘要： A circuit breaker includes a compressive turning spring hung between a movable contact arm pivoted at an end to a handle rotatably mounted to a first reference position and a cradle pivotably mounted to a second reference position and disengageably locked to an abnormal current detection and trip mechanism. Under normal operation of the breaker, the turning spring exerts a contact pressure between movable and fixed contacts. Upon detection of an abnormal current, the turning spring is caused to turn so as to open the contacts. With this arrangement, the dispositions of constituent elements and their interlocking assembly can be simplified.

摘要： There is provided a support system for a forklift power train, having little vibration transmission to a body frame, but capable of effectively suppressing movement of the power train against even a quick movement of a vehicle occurred in such a case as when the vehicle is accelerated, decelerated, turned or the like, and simpler in construction for assembling workability. In the support structure for a power train of a forklift having a counterweight in the rear part of the body frame, while a front side support is provided at one location positioned at a differential gear case or a frame side cross member and in the vicinity of the roll axis of the power train, a rear side support is provided at two locations, on the right and left sides of the roll axis of the power train, respectively, in the rear part of the body frame, thereby supporting the power train at three locations in all.

摘要： A circuit breaker capable of breaking an associated circuit when an overcurrent higher than a rated current keeps flowing through the breaker or upon a short-circuit current. Electric power path in the breaker is partly inserted through an arm of a magnetic material and holding a movable contactor plate of make-and-break contact means, an armature means is provided as pivoted at one end to the holding arm, and a tension spring means is provided between the other end of the armature means and the movable contactor plate to provide a contact pressure. The overcurrent flowing through the path causes a magnetic force to be induced in the holding arm, whereby the armature means is rotated to change the direction in which the force of the tension spring means acts on the movable contactor plate and the latter breaks the contact means.

摘要： An electromagnetic contactor is formed by disposing an inner yoke to oppose at an end to a pole-contacting member provided at an end of an armature in an electromagnet block, disposing the outer yoke to oppose at an end to the said end of the inner yoke so as to restrict the displacement of the pole-contacting member and at the other end to a plunger part of the armature perpendicularly and closely thereto, and inserting a magnetic cylinder into an axial through hole of a coil bobbin of the electromagnet block for passing therethrough the plunger part from the side of the said other end of the outer yoke, whereby any leak of magnetic flux due to coil excitation and that of a permanent magnet disposed between the both yokes can be restrained to be the minimum and a highly efficient operation of the contactor can be realized.

摘要： A circuit breaker having an arc suppressing means disposed adjacent a contactor section and including a first arc running plate extended from a fixed contactor and a second arc running plate opposed to the first arc running plate. The distance between the both arc running plates on the side close to the contactor section is minimized so as not to cause any spatial short-circuiting to occur. At portions of the both arc running plates defining the minimized distance, magnetic arc driving force motivated by mutually oppositely directed arc currents flowing through the respective arc running plates is increased to a large extent, whereby arc shifting to deion grid of the arc suppressing means can be performed effectively quickly.

摘要： A circuit breaker having a plurality of breaker units, in each of which a movable contact of a movable contactor is separated from and engaged with a fixed contact of a fixed contactor from the exterior of a breaker housing by a manual contact opening and closing mechanism which is made operative to close the contacts normally with a tripping link retained as locked to the mechanism and inoperative with the link released from the mechanism by a tripping means responsive to an excess current. The tripping link is operatively interconnected to those in other units through a single coupling rod to cooperate simultaneously with the releasing by the tripping means in either one of the units.
