摘要： A circuit breaker wherein at least a pin sliding surface of a guide hole of a first contact arm, at least a pin sliding surface of a long hole of a second contact arm, and at least a contact surface of a second pin in contact with both the pin sliding surfaces, are treated by low-friction treatment to reduce frictional resistance, and surface-treated to provide surfaces exempt from attachment of molten metal caused by arcing; and furthermore at least the pin sliding surface of the first contact arm and at least the pin sliding surface of the long hole of the second contact arm are hardened to provide both the pin sliding surfaces with greater hardness than the second pin, thereby ensuring smooth movement of the second pin.

The first contact arm in the first pole unit has an elongated guide hole extending in a direction of movement of the movable contact and is directly connected to the operating mechanism. The first contact arm in the second pole unit is connected to the operating mechanism through a cross bar. The second contact arm has an elongated hole extending substantially in a direction of extension thereof. A spring-biased sliding pin extends through the elongated hole and the guide hole, and a stopper is mounted to a base of the second pole unit for limiting movement of the second contact arm beyond a predetermined position.

摘要： A multi-pole circuit interrupter having a first pole unit provided with an operating mechanism and a second pole unit provided with no operating mechanism. Each of the pole units comprises a movable contact, a stationary contact, and a contact arm assembly for supporting the movable contact of the respective pole unit including a first contact arm and a second contact arm pivotally supported by a common pin. The first contact arm in the first pole unit have an elongated guide hole extending in a direction of movement of the movable contact and is directly connected to the operating mechanism. The second contact arm has an elongated hole extending substantially in a longitudinal direction thereof. A spring-biased sliding pin extends through the elongated hole and the guide hole. The guide hole of the second pole unit extends further upwards than the guide hole of the first pole unit so that the sliding pin in the first pole unit starts to slide along the pin braking surface of the guide hole only after the sliding pin in the second pole unit has left the pin breaking surface and moves on the pin sliding surface. As a result, a time delay between the resetting movements of the sliding pin along the pin braking surface of the guide hole in the first and second pole units is provided.

摘要： An automatic trip device for a circuit breaker includes a U-shaped stationary iron core disposed around a current-carrying conductor. The stationary core includes a semicircular recess on one leg thereof having V-shaped bearing surfaces formed at each end of the recess. A movable iron core is positioned across the legs of the stationary core and includes semicircular projection fitted into the recess of the stationary core. A shaft extends through the projection and pivots at each end in one of the V-shaped bearing surfaces. Tension springs connected between the stationary core and one end of the movable core produce opening rotational bias on the movable core. Electromagnetic force produced by an over-current flow through the conductor causes closing rotational movement of the movable core. The disclosed construction results in elimination of undesireable sound vibrations produced in prior art devices under conditions of current flow below overload level.

摘要： An angle adjuster for a golf club shaft includes a pressing part that can advance and retreat towards and away from a space between two pressing force receiving parts. The pressing force receiving parts include grooves configured to receive a golf club shaft. When the pressing part is advanced against the golf club shaft, a bending force is applied to the shaft at a bending location on the shaft that lies between the pressing force receiving parts. This occurs while the shaft is received in, the receiving grooves of the pressing force receiving parts.
