In this study, with an original flow type burner, the response of premixed flame in periodic equivalence ratio fluctuation was examined on the burning velocity and the burned gas temperature of the methane/air flame and propane/air flame (in the equivalence ratio of 0.85, the amplitude of 0.06 and the frequency from 3 Hz to 50 Hz) . This observation reached the following results (1) in a certain range of the fluctuation frequency f, the fluctuation widths of the burning velocity and the burnt gas temperature were larger than those estimated for the equivalence ratio fluctuation in the mixture at the burner exit. (2) The fluctuating width of apparent equivalence ratio A of the mixture flowing into the flame front, which was measured through the relationship between equivalence ratio and burnt gas temperature for the stationary flames, were at the maximum at a certain range of the f, regardless of the kinds of fuel. (3) Within the frequency range in this study, A of methane/air flames was larger than that of propane/air flames.

Two novel placement methods for E-beam testing pads are proposed to improve the placement ratio in multilevel-wiring LSIs. In the first method, which is for the case where upper-level wires obstruct the placement of testing pads, stepped vias are introduced in testing pads so that testing pads can go around the upper-level wires outside the cells. This method has been applied to layout design data of gate-array LSIs containing from 20 to 390-k gates. Results of evaluation confirms that observability reaches more than 99.6%. In the second method, which is for the case where all the top-level wires are used for power supply, an opening is made in the power-supply wires so that a testing-pad to be placed may not short-circuit the wires. As a result of evaluation using actual design layout, resistive increase due to the openings in the wires was found to be so small that the method can practically be used for test pad placement. These proposed methods will be essential for fault analysis of multilevel-wiring LSIs.

Removal of Cd^<2+>, Ni^<2+>, Cu^<2+>, Hg^<2+>, and V^<3+> from the aqueous solutions was examined using waste-paper fly ash produced and provided by a paper-mill. The ash was stirred in 50 ppm metal ion solution at 25℃ for 6h. Concentration of the metal ions was determined by X-ray fluorimetry. Experiment of varying initial concentration of Cd^<2+> gave maximum adsorption of 24 mg/g([B]), which was higher than the results for bagasse fly ash of 1.2 mg/g reported in a literature. Cadmium adsorption increased with increase in pH, while nickel and copper adsorptions were almost constant with increasing pH, being similar values with maximum cadmium adsorption. Adsorption of Hg^<2+> and V^<3+> was considerably lower than the values of above three ions. Metal-ion adsorped ashes were stirred in 0.1N HN0_3, to be desorped for metal ions above 90%.

In order to develop the utility of the waste blood of sheep and cow, authors have studied inclusion of the porphyrins and hemoglobin into the white ghosts prepared from the blood of sheep and bovine by absorption spectroscopy. To improve the enclosing ways effeciently, the conditions of enclosure were investigated about the volume ratio of the white ghosts suspension to the added material solution, and the repeating times of the enclosing and taking-out operations. Enclosing percentage in the bovines ghost membrane is higher than the percentage in the sheep's, especially as to a hemoglobin. The enclosure was more effective in the case of 5:1 than 3:1 for the above ratio. When repeated the on-off operations for inclusion with the sheep's ghost, tetraphenylporphintetrasulfonate complex became more penetrated with the repeating times.

The removal of hexacyanoferrate(III) and (II) ions, [Fe(CN)_6]^<3-> and [Fe(CN)G]^<4-> from aqueous solutions (10-500ppmFe) by coprecipitation with various M^<2+>-Al layered double hydroxide (LDH) precipitates (M2^<2+>= Mg. Mn. Ni, and Zn) has been investigated at 25℃. The higher coprecipitation of [Fe(CN)_6]^<3-> ion was observed at pH higher than 8.5 in the case of Mg-Al system and at wide pH range of 5.0 10.5 in the cases of other systems. The solid products containing a lot of [Fe(CN)_6]^<3->ion were found to have a LDH layer structure with basal spacing of 11.0 A, which means that [Fe(CN)_6]^<3-> ion was intercalated in the LDH interlayer space. However, in the cases of Mn-Al and Ni-Al systems, [Fe(CN)_6]^<3-> ion was coprecipitated as hexacyanoferrate salts only at pH lower than 6.5. In addition. [Fe(CN)_6]^<3-> ion was also found to be removed much easier compared to [Fe(CN)_6]^<3-> ion because of its higher negative electric charge. Finally, the optimum conditions for the removal of [Fe(CN)_6]^<3-> ion were obtained. The coprecipitation method for intercalation of anions into the LDH interlayer space is useful for the removal of harmful hexacyanoferrate ions and other relative cyano-complex anions.

Dufton and Hider secondary structure prediction rules have been successfully applied to soybean glycinin and β-conglycinin subunits. Despite the different amino acid sequences involved, a common distribution of secondary structure was detected throughout these subunits. Each amino acid sequence of the subunits along polypeptide of the acidic and basic subunits caused us to predict highly α-helix and β-structure, respectively. The solvent accessibility reduction ratio in the accessible surface areas of each subunit has been attempted to calculate, based on a set of average residue accessible surface areas of the 21 kinds of amino acid residue produced by Chochia. Beta and basic subunits had higher accessibility reduction ratio than a, a ' and acidic subunits, respectively. Their total gains in the surrounding hydrophobicity of subunits and the corresponding gain ratios have been attempted to compute, based on a set of their average surrounding hydrophobicity values produced by Ponnuswamy et al. Each tendency of their differences in the total gains and gain ratios among their subunits was similar to that in their accessibility reduction ratios.

It is difficult to measure the salt-water intrusion in the field though the environment of the Lake Ogawara consists on a delicate balance of the salt-water intrusion and the salinity circulation. In this study, the amount of the salinity outflow-inflow is estimate respectively by a multiple linear regression analysis and fuzzy reasoning by using only the water level of the river mouth and the Lake Ogawara. The tendency of the amount of the salinity outflow-inflow in winter was able to estimate by the both of a multiple linear regression analysis and the multi-layered neural network.

Lake Ogawara is one of large brackish water lake upon which sea water ascends and trespasses, located in the Pacific Ocean shore of the Aomori southeast. We investigated the water qualities in the lake from August 2002 to December 2003 in order to evaluate the effect of the seawater intrusion and the trophic level in the lake. The vertical profiles of salinity at the center indicated a halocline was always found near the depth of 18 meters throughout the year. Dissolved Oxygen (DO) concentration in the salt layer below the halocline ranged from 0.5 to 2.0 mg/L throughout the observation period. The salt waters near the bottom were almost under hypoxic or anoxic environments. The horizontal profiles of the concentration of chemical oxygen demand (COD) and chlorophyll-a (chl-a) showed the seasonal variation in the surface water near the lake entrance and the center. In the southwest part of the lake near the entrance, COD and chl-a concentrations were highest in summer, while they maximized in April in the center of the lake. All the observed data in the bottom were compared with three standard values which divided the trophic level of lake into three categories. The water quality in the lake is about to approach to eutrophic level.

This report is written about the reformation of education on the"Institit Universitaire de Technologie"in France (abriviated "IUT") comparing with the education of the National College of Technology in Japan (abriviated "Kousen"). We have researched the system of short higher education of technology in main countries of EU (i.e. French, Germany, the Netherlands, and Belgium). Now many people in France go to the Grands ecoles, University and IUT. The departments and specialties of IUT are increasing and many foreigner students study in the IUT. After acquired the Diplome Universitaire de Technologie (abriviated "DUT"),most students learn in one year at many courses of the Post-DUT in which many specialties are arranged for meeting the chance of getting the good jod in the speciale region. The education of the TUT brings along the professional competence. The courses of the Post-DUT is changed to the License professinal as the system of higher education of France is reformed to the system of License-Master-Doctorate which is the European standard of the higher education system.

The mechanical physical-properties examinations on a club shaft are of much importance in the application not only to the unbending of a club shaft but to the swing itself. With this in mind, the mechanical experiments were carried out on the shaft by means of adding various weights to the club head. The following were recognized through the experiments: （1）The difference arising from weight changes was not seen in the observation of character frequencies. （2）The numerical difference of wave forms arising from attenuation half-life was not observed by each weight. （3）Although the situations of the amplitude of half-life were electrically observed, the reaction to each weight was fixed. From these things, when seen from mechanical and electrical experiment results of attenuation half-life and character frequency, the experimented shaft showed the regular and stable reaction or behavior to every weight, and it turned out that the reproducibility of an unbending function is high. Since it leads to the accurate flight of a ball, this high reproducibility can be said to be an important factor for a club shaft.

The questionnaire about the physical education was carried out to the 4th and 5th grade students. The conteuts are about their likes and dislikes of sports, their daily sporting activities, existence of confidence in their physical strength, and so on. Moreover, the author observed how much their concern to the physical education would be reflected in actual lessons by correlation analysis with the teacher's evaluation of them. Consequently, the following were known : 1. As to likes and dislikes of sports, many 4th and 5th graders chose categories 4 and 3, and the rate was as high as 65% to 72%. They can be said to be sports-loving people in general. 2. In the reply to the question "What do you ask for the physical education?" many 4th and 5th graders thought of the physical education as a place of refreshment, i.e., a place for a change. As for the rate, both grades exceeded 50%. 3. About the sporting activities other than those in the physical education and the activity time, 50% of the 5th graders answered they do no sporting activities, and activity time of the others was less than 30 minutes. Consequently, sporting activities pose a problem for upper graders. 4. To the question "Do you have confidence in your physical strength?" the level of 50% of the 4th and 5th graders answered "Medium". 5. As for the correlation of upper graders' consciousness about the physical education and the evaluation of their achievement in the physical education, it turned out to be significant by 0. 1% to 5% in the 4 classes out of the 8.
