| 抄録 | Nested dissection method is an elimination method for a set of linear algebraic equations with minimum fillins. Physically it divides a domain into four subdomains, and each subdomain is again divided into four. This procedure is repeated till all nodes are included in some subdomains. Using this characteristic, the authors examine the efficiency of the method on the transputer. |

| 抄録 | Tensile strength and elongation of cast magnesium reinforced with titanium fiber were measured by tensile test. The pull-out test of a titanium rod partially embedded in a magnesium matrix was performed to evaluate interfacial bonding strength between magnesium and titanium. It was found that when the fiber volume fraction was changed from 1% to 14%, the tensile strength was improved with increase of volume fraction, while the improvement of elongation tended to be restrained beyond the volume fraction of 10%. The interfacial strength was revealed to be strong, and this was substantiated by the scanning electron microscopy showing an excellent wettability between the titanium fiber and the magnesium matrix. |

| 抄録 | Fine particles of Ti-Mo alloy were prepared by evaporation. When Ti-40at % Mo alloy was evaporated on tungsten filament, fine particles of Ti contaminated with W were obtained. These particles were polyhedron in shape and 10～250nm in diameter. Average diameter and size distribution increased with pressure of argon gas (100～600 Torr). When pure Ti was placed on the Mo filament and evaporated from melt down of heated Mo filament in helium gas, fine particles of pure Ti and of Ti-Mo alloy were obtained. In this case, Ti particles were of indeterminate form and of several tens nm in diameter, and their diffraction pattern was of common α-Ti. On the other hand, composition of the Ti-Mo particles was determined to be 18at % Mo by an analysis of EDX. Structure of Ti-Mo particles could not be determined because their diameters were more than 600nm. The temperature of Mo filament, for the most part, was about 1800℃, and there pure Ti particles were produced. The temperature of the fused part of the filament was locally higher than 2600℃, and there Ti-Mo particles were produced. Fine structures of contact region among some Ti particles were observed with HRTEM. |

| 抄録 | The numerical feasibility of determining soil water retention and hydraulic conductivity functions simultaneously from one-dimensional transient flow experiments in the laboratory by parameter estimation method is evaluated. Soil hydraulic properties are assumed to be represented by van Genuchten's closed-form expressions involving two unknown parameters: coefficients α and n . These parameters are evaluated by nonlinear least-squares fitting of predicted and observed pressure head with time. Gravity drainage experiments are performed for Toyoura standard sand to evaluate the adequacy of this proposed method. |

| 抄録 | This paper describes a method to design an antenna to focus millimeter-wave beam generated by a gyrotron. The antenna, which has been proposed by the authors, consists of a stair-cut circular waveguide and two cylindrical reflectors; one is elliptic and the other is parabolic. Its principle is based on the geometrical optics though slightly modified to consider the diffraction effect. Results of low-power experiments agree well with the design on beam direction, beam width and the position of the focal point. At 35.5 GHz using TE(01) mode, a focused beam with half-power thickness of 13 mm x 10 mm was obtained. This type of antennas find applications to millimeter-wave scattering measurement in fusion plasma research and high- energy-density source for material heating. |

| 抄録 | (001)-oriented Ti(2)O(3) films were epitaxially grown on a(001)-face of sapphire single-crystalline substrate by an activated reactive evaporation method. The formation ranges of stoichiometric and nonstoichiometric Ti(2)O(3) films were determined as a function of the substrate temperature (Ts), the oxygen pressure (Po(2)) and the deposition rate. Stoichiometric Ti(2)O(3) films were grown at Ts≧673K under Po(2)≧1.0×10(-4)Torr, which showed the metal-insulator transition with a sharp change in electrical resistivity from 3.5×10(-2) to 2.6×10(-3)Ωcm at 361K. Nonstoichiometric films prepared under less oxidized conditions did not exhibit the transition. The nonstoichiometry of the Ti(2)O(3)films was discussed in terms of excess Ti ions. |

| 抄録 | Poly(methyl methacrylate) substrates were immersed in suspensions containing bioactive 50CaO･50SiO(2) (mol%) glass particles (45 μm in diameter) and a 6:4 (volume fraction) mixture of ethanol and THF, and an ultrasonic energy was applied to the system. A layer of glass particles was implanted and covered more than 50% of the substrate surface. Thin film X-ray diffraction patterns and FT-IR reflection spectra indicated deposition of apatite on the glass-implanted substrates after they were soaked for 12 h in a simulated body fluid similar in apatite-deposition ability to the human blood plasma. Flake-like apatite crystallites formed on the substrate soaked in SBF for 3 days. |

| 抄録 | Direct patterning of copper coated ceramic circuit board is experimentally investigated with Q-switched Nd:YAG laser in order to shorten the time of the trial manufacture of electronic circuit board and to adapt the flexible design change. It is pointed out that the fast direct patterning the speed of which reaches about 100 mm/s is possible if the repetition frequency and the average power are selected properly. Furthermore cutting off and/or drilling of ceramic board are also possible under the condition that the repetition frequency is less than 3kHz. This technique makes it possible the mask1ess patterning of ceramic circuit board which has been widely used recently in place of conventional glass-epoxy or phenolic resin circuit board, and it leads to the shorter time limit of delivery as compared with the conventional end-milling method. |

| 抄録 | A cylindric mirror was used, in place of a parabolic mirror, to collimate the crescent blue laser beam radiated from the Cerenkov SHG in channel waveguide configuration. The cylindric mirror radius is requested to be twice the focal length of the parabolic mirror. The focusing effect of the cylindric mirror in collimation can be compensated by slightly lifting the mirror in its normal direction. Under the condition that the mirror was declined by 5.56° and lifted by 25 μm, we got the collimated beam with divergence angle less than 1.3 mrad. In the focusing experiment, the collimated beam was focused with spotsize of 1.8 μm. The details on the analysis and experiment are reported. |

| 抄録 | We present a theoretical study of Si(1-x)Ge(x) alloys based on tight-binding molecular dynamics (TBMD) calculations. First, we introduce a new set of nonorthogonal tight-binding parameters for silicon and germanium based on the previous work by Menon and Subbaswamy [Phys. Rev. B 55, 9231 (1997); J. Phys: Condens. Matter 10, 10991 (1998)]. We then apply the method to structural analyses of Si(1-x)Ge(x) alloys. The equilibrium volume and atomic structure for a given x are obtained by the TBMD method. We also calculate the bulk modulus B, elastic constants C(11), C(12) and C(44) as a function of x. The results show that the moduli vary monotonically, but nonlinearly, between the values of Si crystal and Ge crystal. The validity of the results is also discussed. |

| 抄録 | The proportion and number of lymphocytes in the airways were analyzed in 15 patients with a high proportion of lymphocytes in bronchoalveolar lavage (BAL) fluid (more than 30%) and in 17 patients with less than 20% of BAL lymphocytes. 1. Both atopic and nonatopic asthma patients with a high proportion of BAL lymphocytes were aged more than 50 years. In contrast, the age of patients with less than 20% of BAL lymphocytes ranged widely, from 29 to 63 years, in the two asthma types. 2. Age at onset of the disease, serum IgE levels, and ventilatory function test were not related to the proportion of BAL lymphocytes. 3. In patients with a high proportion of BAL lymphocytes, the mean proportion of these cells was 47.3% in atopic patients and 36.4% in non-atopic patients, i. e., there was no significant difference between the two asthma types. The absolute number of BAL lymphocytes in these patients was significantly higher in atopic (5.62×10(6)) than in nonatopic asthma (0.77×10(6)) (p<0.01). These findings show that an increased number of lymphocytes in the airways is clearly related to patient age and IgE-mediated allergic reaction. |

| 抄録 | Delayed cutaneous hypersensitivity towards Candida albicans was examined in 200 patients with bronchial asthma in relation to patient age and the level of total IgE. 1. Delayed skin reactivity towards C.albicans was depressed in the patients between the ages of 10 and 20 and in those over the age of 61. A significant difference was present in delayed skin reactivity between the groups of 10-20 and 41-50 years old. 2. The frequency of the patients with positive delayed skin reactivity towards C.albicans was the highest in those with low levels of total IgE (0 -100 IU/ml) and the low est in those with high levels of total IgE (over than 1001 IU/ml). The results suggest that cell-mediated immunity towards C.albicans is depressed re lating to atopics in the patients between 10 and 20 and to aging in the patients over 61. |

| 抄録 | Twenty six patients with bronchial asthma was classified by clinical symptoms and singns (clinical diagnosis), and the classification by clinical diagnosis was compared with the classification by a score calculated from clinical findings and examinations (score diagnosis). 1. Of 12 subjects with type Ia classified by clinical diagnosis, 8 cases with 0 to 49 ml/day of expectoration were evaluated as type Ia by score diagnosis. While four type Ia cases with 50 to 99ml/day of expectoration were calssified as type Ib by score diagnosis. The increased incidence of eosinophils in bronchoalveolar lavage fluid (BALF) of these four cases was similar to the incidence in type Ib cases with hypersecretion. 2. All of 6 subjects with type Ib by clinical diagnosis were estimated as type Ib by score diagnosis. 3. Of 8 cases with type II by clinical diagnosis, 7 cases were assessed as type II by score diagnosis. One case with type II by clinical diagnosis and with the score of 10 points was evaluated as questionable type II by score diagnosis. |

| 抄録 | Differences in morphological changes of basophils between antigen and anti-IgE stimulation were examined in atopic subjects in relation to histamine release. 1. Antigen- induced release of histamine was remarkably more rapid and larger at any incubation time than the release by anit-IgE, and a significant difference was found at 3 to 9 min. 2. Decrease in number of basophils induced by antigen was significantly higher for 12 to 15 min incubation time than that by anti-IgE. 3. Morphological changes of basophils representing increased motility such as an increased ratio of short to long axis diameter (L/S ratio) and an increased incidence of basophils with localized granules (LG) were more often observed in antigen stimulation compared with anti-IgE, and the L/S ratio of the cells was significantly more increased in antigen stimulation at 6 and 15 min. 4. There was no difference in morphological changes of basophils showimg swollen type (degranulation) such as an increased mean diameter (MD) of the cells between antigen and anti-IgE. These results suggest that antigen activates basophils and induces increased motility more strongly than anti-IgE, but the action on degranulation was not different between the two agents. |
