    우리나라에 전기가 밝혀진지 어언 80년, 그간 공급능력 확충을 위하여 송전전압 및 1차 배전전압의 승압은 이미 시행하여 오고 있으나 2차 배전전압의 승압은 일반가정 전기수용가와 직결됨으로서 가전기기 보상의 어려움등 제반여건불비로 시행치 못하였으나 금반 2차 배전전압 단기승압계획이 정부에 의해 공포되었다. 이 승압사업은 백년대계를 위한 국가적 사업임과 동시 전기혁신적 사업이며 에너지 자원절약면에서나 전기수용가에 대한 서어비스 향상면에서도 그 의의가 있다 하겠다.

    Intermittent failures exercise their effects only part of the time but constitute a dominant factor for the field failures. We consider the data raliability of the partially self-checking network with which a single intermittent failure will be recovered by a rollback method. Even if the self-testingness of partially self-checking network is guranteed for a set of permanent failures, it sometimes may not be so for intermittent failures. We introduce the notion of error residual and provide the basis for calculating the data reliability. Both the duration of each intermittent failure and the occurrence interval of successive ones are assumed to be negative exponentially distributed; the convolution of the intervals is distributed according to an Erlangen distribution.

    A new method of realizing the field effect transistor with a sub-.mu. channel width is described. The sub-.mu. channel width is made possible by etching grooves into n$^{+}$ pn$^{[-10]}$ n$^{[-10]}$ structure and using p region at the wall for the channel region of the Metal-Oxide-Semiconductor transistor (MOST), or by diffusing two different types of impurities through the same diffusion mask and using p region at the surface for the channel region of MOST. When the drain voltage is increased at the pn$^{[-10]}$ drainjunction the depletion layer extends into the n$^{[-10]}$ region instead of into p region; this is also the secret of success to realize the sub-.mu. channel width. As the result of the experimental fabrication, a microwave MOST was obtained. The cut-off frequency was calculated to be 15.4 GHz by Linvill's power equation using the measured capacitances and transconductance.

    This paper is prepaped, based upon its foundation of the design, first studying the rotor impedance of single and double layer cylindrical induction motor with solid iron rotor, and then inducing torque equation, from it. Classified were some design factors for this design from the result for above and there carried out the evidence of these design and theory after making experimental motors with solid iron rotors and examining torque characteristics.
