Japanese thought of territorial waters in the Edo era developed connecting with the coastal fishery and being influenced by the approach of foreign ships. In Cremean War 1854, Japan rejected the demand of England on mainting neutrality. In Prussian-French War 1870, Japan declared the neutrality and accented the theory of 3-miles territorial waters. But the system of Japanese waters has not been legislated till 1977. Kairi, Hiro, Shaku and Knot were introduced by the Meiji Government. Especially Kairi took the lead in the history of adoption of the metric system.

The estimating system for the frequency stability was manufactured. The measurement, the data aquisition and the estimation of the stability, etc. are all controlled by a microcomputer PC 8001 mkII. Allan-variance and power spectral density was calculated as the measure of the frequency stability in the time-domain and the frequency-domain respectively. It was found that the tested quartz crystal oscillator had the stability of 1×10^<-11> at 1 sec averaging time and its power spectral density was designated by the sum of the terms of 6×10^<-25> f^<-2> (random walk noise) and 1.5×10^<-22> f^0 (white noise).

The great development of computers and their rconnected terminals is producing the development of image technology and also the easy operation by networks for users. Given assistance of the special fiscal 1988 and 1989 budgets in the Faculty of Engineering, Tokyo Institute of Polytechnics, this project started in cooperation with the laboratories interested in the application of the image information. In order to fulfill graphic functions and image processor simultaneously by one system, which will be the most powerful research tool in the near future, IRIS 4D/50GT graphic computer and NEXUS image processor were purchased and connected with VME BUS so that a part of the multi-functional system was completed. As several analysis about the information of the three-dimensional image were conducted using the system, the abstract is reported.
