    摘要: A control system for a blind microwave radiation tool a workpiece is described. The controlled system automatically tunes the cavity containing the workpiece. The control system automatically controls the temperature of the workpiece according to a predetermined temperature versus time schedule. Control system automatically determines when the workpiece has reached a particular predetermined physical condition. To achieve these results the control system automatically monitors applied power, reflected power or current temperature and automatically controls the microwave cavity volume and shape and launch structure including antennae location, cavity short location, cavity diameter, coupling loop position, etc. in order to maintain the cavity in resonance and to determine when to exit without operator intervention. Control system can run on a small computer or an embedded controller and is useful for automatically curing polyamic acid to polyimide to a predetermined percent cure, processing preimpregnated glass cloth in a continuous manner which can be used in circuit boards and drying and partial curing of web-like materials automatically without operator intervention.

    摘要: Active devices that have either a thread or a ribbon geometry. The thread geometry includes single thread active devices and multiple thread devices. Single thread devices have a central core that may contain different materials depending upon whether the active device is responsive to electrical, light, mechanical, heat, or chemical energy. Single thread active devices include FETs, electro-optical devices, stress transducers, and the like. The active devices include a semiconductor body that for the single thread devices is a layer about the core of the thread. For the multiple thread devices, the semiconductor body is either a layer on one or more of the threads or an elongated body disposed between two of the threads. For example, a FET is formed of three threads, one of which carries a gate insulator layer and a semiconductor layer and the other two of which are electrically conductive and serve as the source and drain. The substrates or threads are preferably flexible and can be formed in a fabric.
