抄録 An optimal control is giyen for regulating power distribution in a nuclear power reactor which has cylindrical geometry. The space dependence of the system is described by expanding space depenident variables by Helmholtz modes. Results are obtained through the principle of optimality and are described by the Riccati-type algebraic equation that the optimal feedback coefficients should satisfy. Use of an integral equation as the system equation makes it possible to deal with actual controlling apparatuses: control rods or rod clusters.

抄録 The equipment measuring the critical flicker fusion frequency (CFF) is made in order to measure many subjects' CFF at the same time. This equipment is defined the multi-flicker. The equipment measuring CFF, used until now is defined the mono-flicker. It is analysed what factors influence CFF strongly. Then it is made clear that CFF value measured by the multi-f1icker can be used to show the brain weariness as well as that of the mono-flicker, and the vigual angle and the intensity of illumination in the room influence CFF value strongly.

抄録 In paper 7) we concerned ourselves with the conformal mapping onto circular-radial slit covering surfaces over the whole plane and its extremal property. In the present paper we shall concern ourselves with the conformal mapping onto circular-radial slit covering surfaces of annular and circular types and their extremal properties (Theorems 1.1 and 2.1). Especially the extremal property with respect to the radial slits is new. The results are stated only for the case of the planar domain of finite connectivity. The method suggests the possibility of an extension to the case of a domain of infinite connectivity or an open Riemann surface of finite genus. We shall concern ourselves with this problem in the subsequent paper.

抄録 The preparative method of giant single crystals of PEO and the experimental results of them by x-ray diffraction and electron microscopy are described. The crystallization of PEO was carried out in a two dimensional crystallization apparatus. From the tridirectional x-ray diffraction patterns on the resulting platelike crystals, it was confirmed that these crystals have a single crystal-like orientation at high supercoolings, the [401] axis is parallel to a growing direction and the [001] axis is perpendicular to the wide surface, and a double orientation at low supercoolings, two axes of [421] and [421] are parallel to a growing direction and the [001] axis is perpendicular to the wide surface.

抄録 The batch chemical reaction is chosen as the process model to be optimized and the rate constants are functions of pressure only, as the reactions are assumed to occur isothermally. The time optimal control problem considered here means to determine the minimum time path from the given initial compositions to desired final compositions by manipulating the process pressure. A gradient method or a steepest-ascent method is applied to determine the control variable program by using the high speed digital computer. Numerical solutions are presented for the following three cases: (1) no constraint on the operating pressure ...... open and matched terminal constraint. (2) constraint on the operating pressure ...... open terminal constraint. (3) constant operating pressure ...... open terminal constraint.

抄録 Multi-item flexible manufacturing systems have been spread to correspond the short life-cycle and the diversification of products. Part handling plays an important role to operate multi-functional robot efficiently in these systems, and many jigs are widely used to hold a part. They should be exchanged at once according to changing products. In this paper, we propose a pin jig which holds a part with two pins, and design method of the position, length and diameter of those pins for a cylindrical part. This jig has the following characteristics. As a surface of the jig is inclined to use gravity, the part can be fixed without any external forces. Therefore the structure of jig becomes simple, and loading and unloading of a part becomes easy for a robot hand.

抄録 Numerical simulations of a single layer recurrent neural network model in which the synaptic connection matrix is formed by summing cyclic products of succesive patterns show that complex dynamics can occur with the reduction of a connectivity parameter which is the number of connection between neurons. The structure in these dynamics is discussed from the viewpoint of realizing complex function using complex dynamics.

抄録 We developed the disassembly system that uses the impulsive load and disassembly tools to disassemble used appliances economically. The main components of this system are impulse hammer, a lift table and developed disassembly tools. Several types of disassembly tools are developed to punch out fastened portion on a part and cut off the shaft of screw or connection pin of IC-chip. A simulation model is proposed to explain and formulate how the fastening point of product is broken and cut. Three kinds of disassembly tools are designed. The actual disassembly system is developed by using proposed simulation models and disassembly tools.

抄録 This paper describes a new measurement method and principle of detection of biodynamics using bioelectrical impedance method based on four-electrode technique with sinusoidal constant current. This method uses a human body itself as a part of the sensor. First, we show a bioelectrical impedance measuring device and the change of bioelectrical resistance is measured in human movement. Second, we proposes a principle of detection of biodynamics based on correspondence of magnitude, form and stability of movement to impedance waveform. Hence we can use this method for the judgement of sports skill using the impedance characteristics.

抄録 In EDM, the machining characteristics greatly depend on the energy distribution. Therefore, it is very important to clarify the energy distribution for understanding various phenomena in EDM. In this paper, the energy distribution in EDM with graphite electrode is investigated by measuring the temperatures of electrode and workpiece. Experimental analysis shows that the material removal rate depends on energy density while the electrode wear greatly depends on the adhesion of heat resolved carbon from machining fluid, and the energies distributed into electrode and workpiece are almost constant regardless of pulse duration.

抄録 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.

抄録 QCTおよびDIP法による測定値の相関性について検討し,DIP法による腰椎骨塩量の推定および,スクリーニングへの適用について考察した。QCT値とΣGS/DやMClとの相関関係の検討では.対象のQCT値が低値か高値かによって相関関係がかなり異なることが明らかになった。すなわち,QCT値が低い領域は,QCT値と,ΣGS/DやMCIに明らかな正の相関関係が認められたが,一方, QCT値が高い領域では,相関関係は認められなかった。また,ΣGS/D=2.8mmAI以上,またはMCI=0.48以上の症例においては腰椎圧迫骨折の危険は小さく,ΣGS/D=1.8mmAI以下,またはMCI=0.24以下の症例においては腰椎圧迫骨折の危険が大きい可能性が示唆された。

抄録 Serum IgE levels and IgE antibody values in relation to patient age were examined in 50 patients with house dust mite (HDm) sensitive asthma, 1. IgE antibody values to HDm were highest in patients between the ages of 10 and 19, and the values generally low in those over the age of 40. 2. High IgE antibody values to HDm were accompanied by high serum IgE levels in patients between 10 and 19. IgE antibody values and serum IgE levels were in general low in patients over age 40. In patient under age 9, serum IgE levels were less than 500 IU/ml in 5 of the 10 subjects despite an increased value of IgE antibodies to HDm. These results suggest that an increased production of IgE antibodies to HDm is usually accompanied by an increased production of total IgE in younger subjects. However, an increase in production of IgE antibodies is not always related to an increase in production of total IgE in patients under age 9. The results also show that production of IgE antibodies to HDm and total IgE is in general low in older patients despite the hyperreactivity to HDm.

抄録 Relationship of the proportion of lymphocytes in bronchoalveolar lavage (BAL) fiutd to IgE-mediated reactions and to ventilatory function was studied in two age-matched asthma groups : group A of 11 subjects with BAL lymphocytes over 30% and group B of 11 subjects with BAL leyphocytes less than 10%. Of the eleven subjects in group A, 3 (27.3%) were atopic and 4 (36.4%) were non-atopic. The proportion of BAL lymphocytes in subjects with serum IgE level more than 300 IU/ml, who were all older than 50 years, was significantly higher than that in subjects with serum IgE less than 100 IU/ml in group A (p<0.05). While of the eleven subjects of group B, 5 (45.5%) were atopic and 4 (36.4%) were non-atopic. The value of % V(25) was significantly higher in the atopics compared with the non-atopics in group A (p<0.05), although no significant difference was found in the value of % V(25) between the two asthma types in group B. The results show that an increased number of lymphocytes in BAL fluid may be enhanced by IgE-mediated allergic reactions in the elderly, and that the decreased value of % V(25) may be associated withan increased number of lymphocytes in BAL fluid in non-atopics.
