    摘要: A novel microwave power divider is disclosed that is a combination of an ort junction circulator and a novel isolator-mismatch device for each circulator port other than one input port and divides microwave signal power incident to the input port into any desired ratio among the output ports and isolates all the ports from microwave power reflected back toward the divider after being propagated through the divider and thus prevents interaction among line devices, e.g. amplifier units, that are fed by the output ports. Also a novel microwave power combiner is disclosed that is a combination of an N-port junction circulator and a novel isolator-reflector device for each port other than one output port to combine at the one output port identical microwave signals or microwave signals that differ in frequency or phase incident to the isolator-reflector devices. The microwave power combiner, like the microwave power divider, provides isolation among the signal transmission lines. Also a novel solid-state microwave power amplifier is disclosed that includes the novel power divider, a solid-state power amplifier unit for each power fraction from the outputs of the divider and the novel power combiner for the amplified outputs of the power divider.

    摘要: The present invention is directed to a cover for a container. The cover includes a moveable member and a motor having armature connected to the moveable member. A sensor generates a sensing signal when motion is detected. A controller is connected to the sensor and the motor. The controller receives the sensing signal from the sensor and activates the motor to move the moveable member from a closed position to an opened position. After a predetermined period of time, the controller deactivates the motor to move the moveable member from the opened position to the closed position.

    摘要: A standby microwave transmitter power amplifier tube is switched into a mowave power distribution system for a phased array in microseconds when any transmitter tube feeding any one of the radiating elements fails and all the radiating elements continue to be fed by respective transmitter tubes after the switching is completed, the switching being accomplished by changing electrical length of a quarter-wavelength waveguide stub to one-half wavelength by switching a reciprocal latching ferrite phase shifter in the stub, in response to termination of microwave power from one of the feed tubes.

    摘要: Method of stretch forming a workpiece comprising placing the workpiece on a former, gripping the workpiece by at least one gripper, pulling the workpiece to a desired configuration over the former by the at least one gripper, disposing a force-applying device between a fixed reaction workpiece and the workpiece and applying a desired force to the surface of the workpiece, such that the force is reacted by the force-applying device and the reaction surface. The position of the force-applying device is altered by a positioning device such that as the force is applied to different parts of the surface of the workpiece the force continues to be reacted through the force-applying device and the reaction surface in preference to being reacted through the positioning device. The positioning device is also operable to alter the position of the force applying device independently of the position of the grippers. Apparatus is also provided for carrying out the method.
