| Abstract | Large isotope effects have been observed in various kinds of hydrogen bonded ferro / antiferroelectrics. In clariflying their origin, themodynamic properties of the hydrogen bond are of essential importance. Two numerical methods are applied to analyze the model for isolated hydrogen bond at finite temperatures and the results of excited energy levels of proton or deuteron are examined. It is found that the second excited state is not far enough from the first excited state to be neglected discussing themodynamic properties of hydrogen especially in their ordered states. |

| Abstract | Parameters characterizing the structure ot confined Yukawa system are estimated for 'dusty plasmas', clouds of charged macroscopic particles formed near the boundary between plasma and the sheath and leviated by negatively biased electrode. When we have dust particles with different ratios of charge to mass, they form a two-dimensional Yukawa mixture or separate two-dimensional one-companent Yukawa systems, depending on the charge density in the sheath and number density of dust particles. In order to provide a basis for numerical simulations on Yukawa mixtures including Coulombic case, we summarize mathematical expressions necessary for molecular dynamics. |

| Abstract | In a stiffness estimation of living body, an internal structure under the skin influences the measured results. Because a different stiffness of body caused by bones and muscles is obtained. In this paper, by using a measurement system of mechanical impedance, the relations between a viscoelasticity and a distance from the surface of silicone-gel model is calculated. This relation is applied to silicone-gel tumor model and a shape and a viscoelasticity of semi-sphere silicone-gel tumous are estimated. The obtained results are expressed as a reconstructed 3-D image of shape / viscoelasticity. The revised curve-fitting of mechanical impedance and the cancellation of peripheral vibration influence are proposed in order to increase an estimation acccuracy. |

| Abstract | This paper describes a new measurment method and principle of power line interference elimination in ECG signal using inverse loop and AC power line configuration (APC). First, we considered that magnetic induction effect not only depend on a conductive loop area that formed by shielded wires that connect the object and amplifier but also effect of body area effective must be considered. It is simple and useful because interference can be eliminated to very small value show that the condition and it can be applied in a real ECG signal recording. Second, results show that the contribution of displacement currents into the object especially APC in vertical configuration is smaller than it in other one. Because this method is so easy that it is convenient to be used to understand some aspects of power line interference elimination phenomenon. Hence we expect that this method can be used as one of improvement method in measurement system of ECG signal recording. |

| Abstract | 末梢動脈の慢性閉塞性疾患に対する血行再建術の予後は不良で，虚血肢の治療には一定の見解が乏しく非常に難澁するものである。組織循環の概念にもとづいた評価法によると，医用質量分析装置を用いた虚血肢運動負荷後のPtCO(2)の脱飽和曲線の型により組織循環の良否が定まる。組織循環の良好な型では，自然予後は良好で，いかなる保存的治療にもよく反応する。一方，組織循環の不良な型の自然予後は不良であるので，人工炭酸泉浴によるPtO(2)の増加，および組織循環量の改善により予後は良好となる。人工炭酸泉浴は，組織循環の良好な症例には治癒促進的に作用し，組織循環の不良な症例にも有効に作用する。 |

| Abstract | Low electrode wear EDM is attained by the adhesion of heat resolved carbon made from kerosine type machining fluid to the electrode end surface. This phenomenon, however, occurs only under long pulse duration. Therefore, the low electrode wear EDM under finishing condition is impossible so far. In the previous paper, the authors developed a turbostratic carbon electrode whose structure is very similar to the heat resolved carbon generated in EDM process and made it clear that the low electrode wear EDM was possible by using the electrode even under finishing condition. In this study, a carbon coated electrode and a SiC coated one which can be made rapidly at low cost were developed and their EDM characteristics were investigated. Experimental analysis pointed it out that both electrodes were effective in reducing electrode wear under finishing condition. |

| Abstract | Poly[(benzo[1,2-d:5,4-d']bissthiazole-2,6-diyl)-1,4-phenylene](cis-PBZT)with a relatively high molecular weight was prepared by a new synthesis route. Properties of the synthesized polymer, such as thermostability, liquid crystallinity etc. were investigated and compared with those of trans-PBZT. cis-PBZT was crystallized from dilute solution and the electron microscopy showed that the precipitate was a rod-like crystal similar to that of trans form. In spite of rigid nature of the back bone, cis-PBZT showed poor crystallinity. |

| Title Alternative | STUDIES ON BALNEOTHERAPY OF DIABETES MELLITUS (Ⅰ). EFFECT OF THE RADIOACTIVE THERMAL BATH UPON THE CARBOHYDRATE METABOLISM AND THE LEUCOCYTE PICTURE IN ALLOXAN-DIABETIC RABBITS. |

| Abstract | The author investigated the effect of the radioactive thermal bath upon the carbohydrate metabolism and the leucocyte picture in alloxan-diabetic rabbits. 1. The author injected 100-200 mg. of alloxan per kg. of body weight intravenously into normal rabbits and produced alloxan diabetes. The triphasic blood sugar response to the injection of alloxan is illustrated in Table 1. and Fig. 1. About a week after the injection of alloxan, the fasting blood sugar values ranged 127 to 331 mg./dl. (Table 3.). 2. In this experiment the alloxan-diabetic rabbits were put in radioactive hot spring and plain water bath, 42-44℃. in temperature. The radioactive hot springs put in use are "Hisui-no-Yu" and "Kenkyusho-sen" (the Loboratory-Spring), both in Misasa Spa, the chemical compositions of which are given in Table 2. 3. In any case, the blood sugar level rose temporarily after the thermal baths for 5 minutes, but the 24-hour blood sugar value after taking a bath was lower in "Hisui-no-Yu" (Rn: 300-400 Mache units) than in "Kenkyusho-sen" (Rn: 10-30 Mache units) (Table 3 and Fig. 2). 4. The glucose tolerance was found to be abnormal in alloxan-diabetic rabbits even 3 months after the injection of alloxan, but this abnormal carbohydrate metabolism tended to become normal by the radioactive thermal bath (Table 5, 6 and Fig. 3, 5.). 5. The radioactive thermal bath in "Hisui-no-Yu" caused increase of leucocyte counts of alloxan-diabetic rabbits more remarkably than the bath in "Kenkyusho-sen" (Table 8. and Fig. 6). |

| Title Alternative | RHEUMATOID ARTHRITIS AND THORN'S TEST |
| FullText URL | 015_029_033.pdf |
| Author | Izumi, Tomokuni| |
| Abstract | In a course of balneotherapy of rheumatoid arthritis, there was no proper standard to judge the therapeutic effect. In this circumstance, Thorn's test and a measurement of red cell sedimentation rate were applied to ten patients with rheumatoid arthritis before and after balneotherpy, and it was found that, although patients before therapy showed a low value of Thorn's test and a faster rate of red cell sedimentation, after released from various symptoms by balneotherapy they had a higher value of Thorn's test and a slower rate of red cell sedimentation. Therefore, these two tests above described may be used as a standard for a judgement of the effect of balneotherapy to patients with rheumatoid arthritis. |

| Abstract | Dependence of precipitation hardening on the distance from specimen surface and effect of the surface layer on the fatigue strength of an Al-1.2mass% Si alloy were studied by microhardness test, transmission electron microscopy and repeated tension fatigue test. Rate of age-hardening was slower in the vicinity of surface than in the interior of the specimen aged at 423K after quenching from 853K. The result of the electron microscopy was that the size ot Si precipitates formed in the vicinity of surface was smaller than in the interior of specimen aged for 6ks at 423K. This difference was considered to be caused by the effect of the surface as vacancy sinks which slowed down the growh of Si precipitates in the vicinity of the specimen surface. A specimen surface layer whose hardness was different from that of the specimen interior was formed at the vicinity of the surface when the specimen was aged at relatively low temperature such as 423K. The fatigue strength in repeated tensile test ot the specimen did not depend on whether the specimen surface layer was present or not. |

| Abstract | In this paper, we propose a method to solve simultaneously facility layout problem and scheduling problem. About a initial random layout planning, the production scheduling and the transportation scheduling of AGV are obtained by using priority rules. From the obtained transportation scheduling, the critical transportation and the closeness rating are obtained. Facility layout is renewed by the combined procedure of genetic algorithm and tabu search in order to reduce the material handling cost. By using this renewed facility layout, the production scheduling and the transportation scheduling of AGV are also revised until no further improvement is possible. |

| Abstract | A method for designing a monitoring system with multiple cameras is proposed in order to supervise and recognize the progress of wide work area. First, a wide view camera is deveeloped by combining several usual cameras so that its visual angle could cover more than π/2. Secondly, A method for determining the number and location points of cameras is proposed by considering the shape of monitored area and the installation cost of cameras. The monitored area is divided into three kinds of basic shape (rectangular form, L form and convex form). For every basic shape area, the camera is located at the vertex pasition, so that the whole area can be monitored by the camera. |

| Abstract | In this paper, we propose a recognition index to evaluate the complexity of discrimination among parts and units. The parts and units are classified into some groups (the number of groups is shown as n) by one characteristic, such as color, shape, size and so on. The recognition index of each is denoted as log(2) (n+1) by the information quantity formula. The recognition diagram shows the classfication of parts and units into only one part and unit by the structure of a characteristic. Further we propose the line balancing method for assembly line based on the working time and recognition index. |
