The purpose of this study is an analysis of the results of the Seoi-nage Technique concerning the angles of the waist to the top of the head and the waist to the wrist, and that of the waist to the top of the head and the waist to the knee of the throwing judoist. The following results were obtained. 1) As for the judoist whose weight is below 60kg, the average angle of pulling hand is 23,22±3.25 for Yuko, 23,18±2.57 for Wazaari and 24.74±1.58 for Ippon. The one of pushing hand is 30.20±3.23 for Yuko, 30.93±3.80 for Wazaari and 30.01±3.02 for Ippon. 2) As for the judoist whose weight is below 65kg, the average angle of pulling hand is 23.40±2.49 for Yuko, 23.41±2.36 for Wazaari and 24.00±3.08 for Ippon. The one of pushing hand is 31.71±1.89 for Yuko, 32.15±3.04 for Wazaari and 32.40±3.26 for Ippon. 3) As for the judoist whose weight is below 71kg, the average angle of pulling hand is 23.98±1.69 for Yuko, 23.78±1.87 for Wazaari and 24.01±1.93 for Ippon. The one of pushing hand is 33.66±2.45 for Yuko, 33.06±2.57 for Wazaari and 33.24±2.53 for Ippon. 4) As for the judoist whose weight is below 78kg, the average angle of pulling hand is 23.49±2.12 for Yuko, 24.52±1.76 for Wazaari and 24.29±1.45 for Ippon. The one of pushing hand is 34.20±1.12 for Yuko, 33.65±2.03 for Wazaari and 34.52±2.02 for Ippon. 5) As for the judoist whose weight is below 86kg, the average angle of pulling hand is 25.14±1.64 for Yuko, 24.68±2.68 for Wazaari and 24.10±1.87 for Ippon. The one of pushing hand is 36.00±1.67 for Yuko, 33.90±2.07 for Wazaari and 34.23±1.54 for Ippon. 6) As far as pulling hand in all weights are concerned, the average angle is 23.84±0.77 for Yuko, 23.91±0.66 for Wazaari and 24.23±0.31 for Ippon. As far as pushing hand in all weights are concerned, the average angle is 33.15±2.25 for Yuko, 32.74±1.21 for Wazaari and 32.88±1.81 for Ippon. 7) From above results, angle from 23 to 24 is the ideal approach for pulling hand, angle from 32 to 33 is ideal approach for pushing hand. I recognize we should research the up and down movement concerning pulling hands form now on.

"Kinsai/Ginsai" is one of fascinating patterns of Bizen-yaki and rarely appears. The formation mechanism of "Kinsai/Ginsai" has been investigated to improve reproducibility on the formation of "Kinsai/Ginsai". "Kinsai/Ginsai" is reproduced by forming carbon film on the surface of Bizen-yaki body or mica in the vacuum evaporator. The color on Bizen-yaki body or mica gradually changed from silver to gold in proportion to the increasing thickness of carbon film. The thickness of carbon film on mica, which was measured by the Aomic Force Microscope (AFM), ranges from 10 to 20nm in silver and from 40 to 50nm in gold.

Both effect of mother wavelet functions on wavelet transform and application method of wavelet transform to sound analysis are described in this paper. As for the former, in case that the speedup of calculation is desired Haar function, in case that qreater importance is attached to frequency components Meyer function, in case that qreater importance is attached to time components Mexican function and in case that both time and frequency components are checked Gabor function can be recommended for application, respectively. As for the later, in case that the distribution of frequency components as time passes is investigated Gabor function, furthermore, in case of minutely examining the difference between consonants and vowels Mexican function and in case of fully checking the distribution of formants in consonants or vowels Meyer function can be recommended for use, respectively. The effectiveness of properly using mother wavelet functions in sound analysis has been found as in the above.

This paper describes characteristics of whispered by compearing with voiced sound in case of plosive consonant. The following characteristics are shown. (1) Formants of back vowel almost agree with those of isolated vowel. (2) Back vowels influence on formants of constnant and attributes of synthesis sounds.
