en: A new supply current test method is proposed for bridging faults in CMOS microprocessor based circuits which are implemented circuit boards with discrete ICs. The method is based on supply current of a circuit under test, which flows when a test program is executed. A commercial microcomputer circuit is tested by the proposed method. In the tests, 98.7% of the bridging faults between two neighboring pins in the circuit are detected within 326 msec. It promises us that the method can be used in production tests of microprocessor based circuits. Also, it is sown that the test program can be developed by means of timing charts in data sheets of the microprocessor.

en: A Study of the Pendulum Equation with a Periodic Impulsive Force --- Bifurcation and Control

en: The pendulum equation with a periodic impulsive force is investigated. This model described by a second order differential equation is also derived from dynamics of the stepping motor. In this paper, firstly, we analyze bifurcation phenomena of periodic solutions observed in a generalized pendulum equation with a periodic impulsive force. There exist two topologically different kinds of solution which can be chaotic by changing system parameters. We try to stabilize an unstable periodic orbit embedded in the chaotic attractor by small perturbations for the parameters. Secondly, we investigate the intermittent drive characteristics of two-phase hybrid stepping motor. We suggest that the unstable operations called pull-out are caused by bifurcations. Finally, we proposed a control method to avoid the pull-out by changing the repetitive frequency and stepping rate.

en: The cage rotor of an induction motor can be diagnosed by the spectra of the stator current, the air-gap flux, and the leakage flux. However, it is not clear how the connection of stator winding, that is, series or parallel, affects on these spectra. In this letter, we discuss the measured results on spectra of stator current and leakage flux in the both case of parallel and series stator winding.
