Filed: 1983-11-04
Abstract: The pulse voltage for the electrode (12) of a dust separator (10) is generated by a thyristor circuit (19) to be transferred to a dust separator through a transformer (16). It being possible that voltage arcings take place at the dust separator (10), there is the risk, in case of a blocked thyristor (20) that from the secondary of the transformer (16) a high voltage is produced at thyristor (20) to destroy the thyristor. To avoid such an occurrence, a detector (27) is provided which is only responsive to sudden voltage drops whereupon the thyristor (20) is enabled to become conductive so that the energy of the secondary circuit may be discharged to the storage capacitor (24) in the primary circuit.

Abstract: PURPOSE: To provide a missile having a high accuracy in flying operation and having a high rate of hitting a target by a method wherein there is provided a control means for controlling a flying direction of the missile in reference to outputs of a plurality of sensing devices. CONSTITUTION: There is fixed a sensing device 10 such as a Piezoelectric element, for example, to detect a load when nozzles 3 are pushed in a lateral direction. A part of injection gas injected out of the nozzles 3 is flowed out in a direction B and then a load of lateral direction is produced in such a way that upper and lower nozzles 3 may approach to each other under a reaction force of the injection gas. Although an output corresponding to the lateral load is produced at each of upper and lower sensing devices 10, the output value is set such that an output from the upper nozzle 3 and an output from the lower nozzle 3 may become equal from each other if both nozzles are formed in a symmetrical manner.  If an operating amount of steering devices 7 against an output of each of the sensing devices 10 is set to a proper value, the missile can continue to fly while correcting to eliminate a displacement of the flying path caused by a displacement of the thrust force. Accordingly, a flying operation of the missile becomes quite stable and a reduction in accuracy of flying of the missile is low.
