The soil names of soil drilling-logs are processed numerically to assess the vertical variation of the soil and thickness of ground.
We analyzed soil drilling-logs down to 12 meters obtained from 149 locations in the eastern region of Muroran, Hokkaido, Japan.
Soil names are classified into 13 sequential categories and a set of numerical scale is given to each of them. The numerized drilling-logs are transformed to the spectra of Haar, Slant, Walsh function system. Using the most substantial function system, spectral zoning maps are drawn to understand the ground condition and to estimate categorized drilling-logs at arbitrary locations.
The results are as follows:
1) Haar function system provides the most abundant information on the ground condition. This function system was adopted in this study since it is most suitable for the spectral analysis.
2) In the average, 99% of numerized drilling-logs can be re-created from the 8 strongest spectra and almost 100% from 16 strongest ones.
3) D. C. spectrum component is most informative on the ground condition.
4) In the zoning map of D. C. spectrum component, zones with small fluctuation of numerized drillinglogs show extremely strong or weak spectrum intensity.

I have performed the three dimensional strain analysis of the Kayo Formation, Kunchan Group around Ban-zaki, middle north of Okinawa-jima by means of the“least square method”and“average method”. The least square method was called the“strain analysis technique 3”and theaverage method was called the“strain analysis technique 2”in my paper (Hayashi, 1994) .The results of both methods are fairly different. The“c-value”is introduced to explain the difference. The difference between the strain ellipsoid calculated using the least square method and associated strain ellipses decreases as the c-value decreases, though the difference between the strain ellipsoid calculated using the average method and associated strain ellipses does not necessarily decrease. Therefore, thestrain ellipsoid obtained by the least square method is expected to approach a true strain ellipsoid asthe c-value decreases, though the strain ellipsoid obtained by the average method is not expected toapproach a true strain ellipsoid.

The transmission system from analyzed data of EPMA (JEOL JXA-733 and JXA-8600) to a personal computer through RS-232C communication line was developed. File format is also converted by this system for some spread sheet programs, such as Lotus 1-2-3 and Microsoft Excel. It is required to make only a few cables for the system. Such a communication method and the convert algorithm using BASIC program may be applicable to various kinds of analyses machines.
