Digital control of a general-purpose switching power supply is one of the key technologies to perform the high reliability and the intelligent function demanded for the next generation. The contribution of this paper is the development of a digital control-based switching power supply. In the developed system, the generation method of the optimal voltage reference in accordance with the output voltage...
In this proceeding, we introduce peristaltic gel actuators as a chemical robot. The polymer gels prepared here have a cyclic reaction network like metabolic process in itself. With a cyclic reaction, the polymer gel swells-shrinks autonomously. The periodic self-oscillating motion of the gel is produced by the dissipating chemical energy of the oscillatory Belouzov-Zhabotinsky (BZ) reaction. We have...
A 300 GHz fully continuous wave gyrotron FU CW I has been developed for application to material processing in the submillimeter wave range. The output power from this gyrotron has not reached the designed one. As a reason of power shortage, it is considered that the electron beam radius shifts from the optimum radius due to installation of additional gun coils to suppress a large anode current. For...
