| Abstract | The experiment for investigating the falling snow melting characteristics of warm water flowing along sheet channels spread on a roof was performed in Tookamachi city, Nigata prefecture from February 6 to February 7, 1995. The sheet surface temperatures at 11 positions in 3 channels were measured. A physical model for a gas-water-snow system was constructed to compare the predicted results with the measured ones. A fully spread uniform water film in the sheet channel was observed in the experiments. The experimental results elucidated that it was feasible to use warm water flowing along sheet channels for melting falling snow on roofs. The temperature drop in the sheet channel mainly depended on the snowfall intensity, atmospheric temperature and wind speed. Under the influence of the roof edge, the temperature drop in the channel next to the side edge was much larger than that in middle channels. A water-snow two phase flow or a snow covered frozen water was experienced temporarily in the lower reaches of the water flowing channel. These suggest that a larger water flow rate is needed for the channel next to the roof edge, and a higher inlet temperature or a greater water flow rate is required for a severe weather condition. There was reasonably good agreement between the measured and predicted water temperatures. |

| Abstract | Rigid polymer, poly(p-phenylene benzobisthiazole), formed lamellar crystals where the molecular chains were oriented perpendicular to the lamellae. It was supposed that, because of wide distribution in the chain length, the lamellar surface bristled with the chain cilia among which many voids were included. Crystallographically, this region afforded us a transitional structure from full to deficient packings of chains. The structure was analyzed using the scanning probe microscope. In the course the method for imaging one molecular chain end was developed. From the images it was concluded that an isolated long cilius did not move so violently at room temperature. |

| Abstract | Poly (ethylene-block-vinyl alcohol), which consisted of both hydrophobic and hydrophilic blocks, was prepared by using polyethylene single crystals as starting material. Polyethylene single crystals reacted with fuming nitric acid resulting in long methylene chains with functional groups such as COOH and NO(2) at the ends (the chain length were almost same as the lamellar thickness of polyethylene single crystal). The functionalized methylene chains were allowed to react with 4-aminostyrene to give corresponding amides, i.e., methylene chains with vinyl groups at the ends (macromer). The macromers were extended by block-copolymerization with vinyl acetate, then saponified resulting in PE/PVA block co-polymer. The block copolymer was molded into sheets which were subsequently heat-treated in contact with hydrophilic or hydrophobic media. Depending on the media, the sheet surface changed at high temperature reversibly from hydrophilic to hydrophobic and vice versa. The surface property was fixed by quenching because both blocks were able to crystallize. Thus the surface of this material can be tailored for various purposes at high temperature, and then used in stable at room temperature. |

| Abstract | In electric power industry, there is a problem of achieving stable joint in different components using high productive and efficient technologies. One type of these components is packages of slices for magnetic circuit of electric motors, transformers etc., which need reliable means for their fixing. Laser welding is proposed to solve this problem as an alternative for existing technologies. The development of the laser welding process is presented based on process simulation, study of heat history and comparison with experimental results. Laser beam additional scanning technique is proposed to improve the quality and efficiency of the joining operation. |

| Abstract | The evaluation of microscopic inhomogeneity of polycrystalline aluminum is performed by measuring the hardness in respective grains. The recently developed ultra-micro hardness tester is used and the effects of the test pattern, the indentation load and the indenting velocity are examined. Then, the relationship between the increase in the hardness caused by the work hardening and the deformation of respective grains are statistically investigated. The hardness testing mode in which the initial load is applied before the onset of measurement gives more stable results than the testing mode without the initial load. The test condition with the indentation load of 9.8mN and the indentation velocity of 0.2 μm/sec seems to be optimum and gives the least dispersion of the measured values in grains. It is shown that the hardness values of respective grains in polycrystalline aluminum as well as their dispersion increase with the applied plastic strain. Discussion is made on the microscopic deformation behavior of polycrystalline aluminum. |

| Abstract | Skin tests, serum total IgE levels, specific IgE antibodies against each allergen, bronchial reactions provoked by allergens and histamine release from basophils are well known as prameters of immediate allergic reactions. The incidence of positive immediate skin reaction to allergens such as house dust, ragweed, Aspergillus Alternaria, Cladosporium and Broncasma decreased with aging. On the other hand, the incidence of positive skin reaction to Candida albicans was higher in cases between the age of 41 and 50 and cases over the age of 61 compared to that in the other groups classified by age. Serum IgE levels was highest in cases aged between 0 and 30. The levels of serum IgE decreased with aging. The incidence of positive RAST scores (more than 2+) and positive bronchial reaction to house dust were highest in cases between 0 and 30, and decreased with aging. However, the positive ratio of these tests against C. albicans were highest in cases between 41 and 50. The degree of histamine release from basophils of asthmatics induced by anti-IgE was consistently high without any correlation to aging when their serum IgE levels were more than 501 IU/ml. In the cases with serum IgE levels of less than 300 IU/ml, basophil reactivity to anti-IgE decreasd with aging. Basophil reactivity to house dust was generally dependent on the levels of specific IgE antibodies against the allergen. Although basophil reactivity to C. albicans was also high in cases with positive RAST scores, some cases with a RAST score of 0+ or 1+ showed high or moderate basophil reactivity. Moderate or high reactivity of basophils was frequently observed in cases between 41 and 50 and cases over age 61. |

| Abstract | Free surface of polycrystalline metal becomes roughened after plastic deformation. The surface roughening is closely related to the inhomogeneity of polycrystalline metals, that is, to the inhomogeneous plastic deformation of respective grains. In the present study, inhomogeneous deformation on the free surface of polycrystalline aluminum specimen during uniaxial tension is studied. The inhomogeneous deformation of grains in the central area of the free surface of specimen is observed by the laser scanning microscope, while the inhomogeneous deformation perpendicular to the surface is studied by the laser scanning microscope as well as the stylus measuring instrument. It is shown that the surface roughness and the strain of respective grains increase with the applied strain. Discussions are made on the change in the surface roughness, the strain in each grain and the slip-line angles with the applied strain. |

| Abstract | The release mechanism of chemical mediators from basophils and mast cells was discussed when these cells were stimulated by different antigens and anti-IgE. 1. Ca(2+) influx into mast cells increased after stimulation by antigen. The increased Ca(2+) uptake by mast cells was inhibited by antiallergic agents, disodium cromoglycate (DSCG) and tranilast, and calcium antagonists, nifedipine and nicardipine. 2. The dose-response curve of histamine release by antigen was different from that by anti-IgE. The maximum release of histamine by house dust was, however, similar to that by anti-IgE. House dust- and anti-IgE-induced release of histamine increased with higher- serum IgE levels. On the contrary, the release of histamine by Candida albicans was not releated to serum IgE levels, and the release by C. albicans did not parallel therelease by anti-IgE. |

| Abstract | Morphological changes of blood basophils activated by antigen and anti-IgE were discussed in relation to release mechanisms of the cells. 1. Basophils activated by antigen and anti-IgE show two different types : A form (pear-shaped) and B from (swollen type), on smear preparartions. 2. Pear-shaped basophils(reactive basophils), which appear after stimulation by antigen and anti-IgE, can be observed by the staining solution for the direct count of basophils and eosinophils. 3. The incidence of reactive basophils increases after addition of antigen. Thus, observation of reactive basophils can be clinically applied for detecting allergen (DCRB ; direct connt of reactive basophils). 4. Observation of morphological basophil response by phase- contrast microscopic motion pictures demonstrates that basophils activated by antigen show two different reponses, increase in motility (oriented movement) and degranulation. |

| Abstract | Blood basophils in subjects with bronchial asthma migrate from blood stream into local allergic reaction sites after inhalation of antigen into airways. The phenomena can be observed by changes in number of basophils in the peripheral blood. The peripheral basophil count is at a normal level in non-attack stage of asthmatics as in healthy subjects. The basophil count increases in pre-attack stages, and decreases during attack stages. These findings suggest that number of basophils changes in close relation to asthma cycle, and that by observing number of basophils in the peripheral blood, it is possible to detect near future attacks. The decrease in number of basophils and histamine release by stimulation with antigen and anti-IgE can be observed in vitro in whole blood and basophils separated by density gradient centrifugation and by counterflow centrifugation elutriation. The decreased number of basophils in the peripheral blood represents migration of the cells into local allergic reaction sites. |

| Abstract | カレジダ特異的IgG及びIgG(4)抗体が,気管支喘息の発症病態に関与しているかどうかについて検討を加えた。カンジダ特異的IgGおよびIgG(4)抗体は, 0-30才の年齢層の症例ではアトピー性素因の強い症例で,また,31-60才の年齢層の症例ではストロイド依存性重症難治性喘息症例で,さらに61才以上の高年令の症例で,その産生亢進が観察される｡これらの症例におけるIgG及びIgG(4)抗体産生は,0-30才の年齢ではアトピーとの関連で,また31-60才の年齢では副腎皮質ホルモンの長期投与と関連して,さらに61才以上の症例では加齢と関連して,細胞性免疫能が低下し,そのためカンジダの発育が促進され,その結果として,IgG及びIgG(4)抗体の産生亢進が見られることが明らかにされている｡すなわち,気管支喘息におけるカンジダに対するIgG系抗体の産生亢進は,cell-mediated immunityの低下と言う共通の基盤を有しており,病因的意義とは必ずしも関連していないことを述べた。 |

| Abstract | ステロイド依存性重症難治性喘息を中心に,温泉療法の臨床効果,作用機序およびその社会的要請について総括的な検討を行った｡1.重症型喘息に対する温泉療法としては,温泉プール水泳訓練,ヨードゾル吸入療法,鉱泥湿布療法などの有効性が高いため,これらの治療法を組合わせた複合温泉療法が現在行われている｡そして,これらの温泉療法は,いずれも細気管支領域の病変(狭窄ないし閉塞)に対して有効であり,気管支肺胞洗浄法(BAL)により観察されるairway inflammationを有する症例が増えつつある現在,極めて有用な治療法の1つと考えられる｡2.入院による温泉療法で軽快した後は,それぞれの地元で継続療法を行うことが症状の安定化のために必要である｡3.重症型喘息は当院への入院例で見る限り,明らかに増加の傾向にあり,薬物療法の限界を越えたこれらの症例の治療には温泉療法が必要であり,周囲環境の変化や高齢化社会を迎えて,その社会的要請は年ごとに増加しつつあると考えられる。 |
