The main subject of this paper is the development of new ROBOT CONTROLLER, which can support MULTI-TASKING and MULTI-ROBOT functions. The system consists of various kinds of CPU modules according to their independent jobs. Acceleration and Deceleration profile is given in order to achieve the smooth robot motion and high cycle time. Further the communication capacity should be upgraded to meet the various kinds of peripheral PA devices.

In this study, the fatigue lives of two kinds of specimens made by co/sab 2/ gas were assessed. The materials for two kinds of specimens were taken out of the virgin carbon steel tubes and used carbon steel tubes, respectively. As a result, it was found that the fatigue lives of two groups of specimens were in the same order of magnitude.

This study was carried out to produce the antisera for the blood typing in cattle. Blood types of eighty cattle were previously determined by 56 kinds of internationally standardized antisera from Japan. The donorrecipient animal arrangements were determined according to tile previously determined blood types of animals by the computer program SS-l for efficient production of antisera. Six kinds of standard antisera, H,B', 12, C2, Z, U2, were produced by isoimmunirzation and absorption methods.

In this study. the fatigue lives of two kinds of specimens made by $CO^2$ gas weld were assessed. The materials for two kinds of specimens were taken out of the virgin carbon steel tubes and the used carbon steel tubes respectively. As a result, it was found that the fatigue lives of two groups of specimens were in the same order of magnitude.

In this paper, the limit temperature for applying maturity method are discussed. 4 kinds of W/C in combination of 7kinds of curing temperature are selected as experimental parameters. According to the experimental results, high curing temperature and low W/C gain in strength rapidly. And maturity rule can be applied less than $30^{\cire}C$ in W/C of 30~60% in the conditions of this experiment.

At the conclusion from the hypothesis testing, there is a possibility of making Type I error and Type II error. The purpose of this article is to use this program in statistics teaching through developing the program for studying on the concept about these two errors, two kinds of the probability of errors by the variation of rejection region, two kinds of the probability of errors by the variation of sample size, the relations of the probability $\alpha$ and $\beta$ by these two errors, and power function, power curve.

Studies were made by measuring number of bacteria, water content, acidity and sugar content on spoiling at different kinds of containers in Summer season, to determine better kinds of containers adoptable for storing cooked rice being the most important food for Korean. It was found that brass, aluminum and porcelain containeres are not recommendable, whereas wooden containers such as a bamboo case (Sokori), a wooden box and a gourd pitcher (Bakaji) are quite useful for at least 24 hour storage even in hot Summer time.

Two kinds of blank shapes, optimum and square, are adopted to investigate formbility. Optimum blank shape is determined to construct an L-shape cup with uniform height and without flange part. For this purpose , rigid-plastic FEM analysis is applied with backward tracing technique. Maximum cup detph and strain distribution are measured experimetally for the products of the two kinds of blank shapes, which are optimum and square.It is confirmed that deeper cup without severe thickness reduction can be obtained fro the optimum shape.

Sixty-eight kinds of aliphatic and aromatic substances peaks from ether extract of Codonopsis pilosulae Radix were shown by GC-Mass. Of them, 3 kinds of compounds were identified as ethyl benzene, acetophenone and 1-phenyl-2-butanone, which are compared with authentic specimen, and one compound was assumed as an aliphatic $C_8H_{16}O\;or\;C_9H_{20}$.

This study surveys the fabric mechanical properties according to the weaving design & finishing conditions of wool fabrics for quality control in the process. For this purpose, 8 kinds of Twill groups and 3 kinds of Plain groups weave fabrics, totally 428 woven fabrics are prepared with change of the yarn count, density and finishing method. Fabric thickness, bending rigidity, extensibility, shear rigidity, formability of the fabrics were measured and discussed with weaving design & finishing conditions.
