Abstract:
Analysis by the use of equivalent circuit method is made for the five-arm ring, and two ways to improve it are found. The improved method can make the center arm entirely match the ring and isolated ideally from the second pair of side arms, and can ...

Abstract:
On the basis of the Threshold Decision rule calculations are made of the error probability of detecting phase-modulated binary codes in the system of Pseudo-random code for the measure of distance. The results are compared with results of measurement...

Abstract:
A resonator with double-curvature mirror to be used as a resonator for optically-pumped lasers at very high efficiency is proposed. This resonator can be regarded as a combination of a stable-resonator and an unstable-resonator. It is a newtype of re...

Abstract:
An investigation of the Ba Sr Tungstate cathode was made. It was found that when the tungstate was prepared at 1050℃ for 2 hours the product was stable in the atmosphere, and storing in air with relative humidity of below 70% for 200 hours, its incre...

Abstract:
After comparing many types of antennas, we decided on the corrugated horn feed cassegrainian antenna. After improvement in input feeding method, the antenna becomes usable. After many flying tests, it proves rugged enough. For X-band, the characteris...
