These days, robot-industry development requires a new motor technology. Robot system is more complex than the other machine ones. They need the simplicity and light weight as robot systems. Moreover, They have to become a high energy efficiency machine. For these reasons, in this paper, the 3-degrees of freedom permanent-magnet spherical motor is proposed instead of existing ones. The proposed motor model is analyzed by using FEA(Finite Element Analysis), for comparing the results, torque of the motor is simulated by derived torque function.

This paper proposes a new test generation algorithm to detect stuck-open faults regardless of tine-skews in CMOS circuits. For testing for stuck-open faults regardless of time-skews, in this method, Hamming distance between the initialization pattern and the test pattern is made 1 by considering the responses of the internal gates. Therefore, procedure of the algorithm is simpler than that of the conventional methods because the line justification is unnecessary. Also, this method needs no extra hardware for testability and can be applied to random CMOS circuits in addition to two-level NAND - NAND CMOS circuits.

This paper presents an analysis of the characteristics in switched reluctance motor (SRM). 2D finite element method (FEM) considering the iron saturation and the actual switching circuit of the SRM drive is applied for the dynamic analysis. The influence of the rotor shape on the radial force and torque ripple is investigated and the optimal shape of rotor pole is proposed to enhance the torque. The radial force characteristics acting on the surface of teeth is investigated by using the Maxwell's magnetic stress tensor method.

We proposed azimuthally continuous nematic domain mode characterized by a cone field induced from patterned electrode structure with a circular slit. This mode has good optical performances such as higher transmittance and wider viewing angle through decreasing the demerits caused by domain walls. We could confirm to these optical characteristics by the manufactured sample.

In this paper, we proposed a novel TFT-LCD pixel structure to compensate ${\Delta}V_p$, which is a maximum value of 1.82V in conventional pixel structure without compensation. We achieved a maximum value of 60mV in proposed pixel structure by integrating a dummy switch TFT in each pixel. The proposed TFT-LCD pixel structure with a remarkably reduced ${\Delta}V_p$ allows ultra high picture quality AMLCDs.
