摘要： This relay has an actuator which has a pair of coupled together driving elements, of a type which deflects according to applied voltage. The actuator deflects in one direction when voltage is applied to one driving element and deflects in another direction when voltage is applied to the other driving element. A bistable switching mechanism has an actuating member and a set of contacts. These contacts are flipped over to a first state when the actuating member is impelled in a first direction and thereafter stay stably in the first state until the actuating member is impelled in a second direction, and similarly are flipped over to a second state when the actuating member is impelled in the second direction and stay stably in the second state until the actuating member is impelled in the first direction. A drive circuit upon command supplies a one shot pulse of relatively short duration to either the one or the other of the driving elements. The actuator is coupled to the actuating member of the bistable switching mechanism, so as when deflecting in the one direction to impel the actuating member in the first direction, and when deflecting in the another direction to impel the actuating member in the second direction. Optionally, the coupling between the actuator and the actuating member of the bistable switching mechanism may have a certain amount of play provided in it, and the driving elements of the actuator may be piezoelectric elements.

摘要： A drive circuit for a piezo-electric element includes a blocking oscillator circuit which has a booster transformer with primary and secondary windings, an oscillation transistor the collector of which is connected to the primary winding of the booster transformer, and a biasing circuit via which a signal at the secondary winding of the booster transformer is fed back to the base of the oscillation transistor so as to produce oscillation by positive feedback. This drive circuit also includes an electric current control circuit means for restricting electric current from flowing through the oscillation transistor when the voltage at the secondary winding of the booster transformer has become equal to or greater than a certain value, and a rectifying element through which the piezo-electric element is connected to the secondary winding of the booster transformer. Optionally, there may be further included a discharge transistor means for rapidly discharging electric charge stored in the piezo-electric element when power input to the blocking oscillator circuit is discontinued. This drive circuit may be used in a relay for driving a piezo-electric element which makes and/or breaks contacts for connecting and/or breaking switched circuits.

摘要： An electrical contact is provided for use in an electromagnetic relay. The electrical contact includes an outer coating containing an element of the VA Group such as antimony, arsenic, phosphorus or bismuth. Thus, the electrical contact does not serve as a catalyst for oxidizing any organic gases which may be produced during the operation of the electromagnetic relay. Accordingly, oxidation of the gases is reduced, carbon generation is suppressed and high reliability of the contact can be achieved.

摘要： The electrical contact alloy is provided comprising Sb and either Au or Ag or both. In such alloys, Sb produces a non-catalytic effect to inhibit formation of carbon from organic gases derived from resin parts. Therefore, when electrical contacts of such alloys are assembled with resin parts into housings, poor contact due to carbon deposition is prevented to increase the useful life and reliability of the electrical contacts.
