The feasibility for fabricating a magneto-optical rotary encoder (MO encoder) has been shown in our previous paper. In this paper, an error corrected recording method to improve accuracy of the MO encoder is described. The recording method utilizes one feature of MO encoder, that is, ability for re-recording. First, an initial recording is made directly from referential encoder to MO encoder and angular errors of the MO encoder are measured. According to the errors, correcting values for canceling the errors are calculated based on Fourier components analysis. Finally, the MO encoder is re-recorded by the correcting values after erasing the initial recording. As the result of experiments, an accuracy of 1.3" for 2250 pulse/rev. and 1.7"for9000 pulse/rev. was achieved by using the error corrected recording method.

In this paper, a new kind of rotary encoder based on magneto-optical storage method is proposed. By using this method, a rotary encoder with small size, high accuracy and high response can be realized. MO encoder is more advantageous than a magnetic scale and optical encoder according to its high response and its high accuracy, respectively. High accuracy can be achieved by rerecording, therefore the error is corrected. Following issues are described: (1) A device for record, playback and evaluation of accuracy of MO encoder has been developed. (2) A necessary condition for record and playback for MO encoder was experimentally derived. (3) The MO encoder made for trial purposes was recorded by 2250 pulses per revolution directly from the referential encoder, as a result, accuracy of 2.5" and reproducibility of 0.079" were achieved.

Since 1962 we have been undertaking a research project on automation of sugar refinary under the contract with the Nagoya Seito Co. Ltd. The Project included survey, analysis, development, design and experiment. The results have been fully made use of in the operation line of the new Tokyo Sugar Refinary recently built in Shinagawa Wharf, Tokyo.There are many difficult problems particular to the control of sugar refinary. As of date, however, we believe this new refinary plant is one step forward in its automation and above the most advanced world level. This new refinary adopts sequence and computer controls. A nearly complete automatic operation is possible in the production line with various batch processes including, in particular, the boiling processes. Both feedback and feedforward controls are employed. For the first time in this kind of plant, an automatic production control was made possible from an over-all point of view.

This paper is an analysis of the structural transition of wooden storehouses in the area around Mt. Yatsugatake. A few types of the structural characteristics can be seen in the same village, and in the same area. In previous studies, it was found that these types of the structural transition were caused by the development of lumbering techniques and changes in the way pine wood was used in the area. First we researched the distribution of wooden storehouses in this area and their details and found out that there were five types of structural characteristics among them. Second, we analyzed each type according to the characteristics of their walls: their lumbering techniques and the length of wood pieces and concluded that the structural types were decided on by a method to build a long wall according to lumbering techniques, We also found that there were some differences in the way of fixing pillars between eastern areas and western ones around Mt. Yatsugatake.

Over the past two decades, many types of homogeneous models have been proposed for the numerical simulation of cavitating flows. Homogeneous models represent cavitation by the media whose density continuously varies from the value corresponding to liquid to that to gas. Recent studies have, however, revealed that the present homogenous models are unable to predict the breakdown characteristics of cavitating hydrofoils. The objective of this study is to clarify causes of such inability of homogeneous models to predict breakdown characteristics of cavitating hydrofoil accurately. Theoretical analysis shows that the present cavitation models inevitably cause kinetic energy loss through expansion and contraction of the media. To illustrate this fact, we computed cavitating flows in a venturi and around a hydrofoil (NACA0015) with a homogeneous model and investigated the computed flow field in detail. It is shown that the expansion and contraction of the media based on the homogeneous model do in fact cause kinetic energy loss and as a result, a region of low velocity appears downstream of the cavity. This results in a decrease of lift force in a partial cavitation condition, which is not observed in the corresponding measurements.

アレルギー疾患合併小児162例 (A群) (男/女: 92/70) とアレルギー疾患非合併小児47例 (B群) (男/女: 25/22) を対象としてインフルエンザワクチンの副反応を検討すると同時に, フマル酸ケトチフェンによる予防内服の有用性を調べた. A群のうち即時型の卵アレルギーを有する症例は15例であった. A群の79例とB群の15例 (計94例) ではワクチンの100倍希釈液で皮内テストを施行した. また, 全209例中44例でフマル酸ケトチフェンの予防内服を施行しその有効性を検討した. その結果, 皮内テスト施行例のうち皮膚スコア2 (発赤径20-39mm) を示した症例は, A群24% (卵アレルギー群での検討では13%), B群20%と差を認めなかった. しかし, 両群とも約10%に皮内テストから予測できない強い即時型局所反応がワクチン接種部位に認められた. 遅発型局所反応は209例中24例 (11%) に認められ, A群18例 (11%), B群6例 (11%) であった. 即時型局所反応ろコアとワクチン接種回数との関係では, 即時型局所反応スコアが2以上を示した割合はそれぞれ, 初年度例の6%, 2年度例の23%, 3年度例の26%, 4年以上例の42%であり, 複数回接種により接種部位の即時型局所反応が出やすくなることが判明した. また, 遅延型局所反応でも同様の関係が認められた. フマル酸ケトチフェンによる予防内服の効果に関しては, 即時型局所反応, 遅延型局所反応ともに有効性が認められた.

哺乳類の食性の長期研究の動向を探るために,BiosisとGoogle Scholerを用いて文献検索を行い,93の文献から99の事例を収集した.食性評価の期間には2年から16年とばらつきがあった.食性の長期研究事例には分類群ごとにばらつきがあり,食肉目(Carnivora)と霊長目(Primates)で多く,齧歯目(Rodentia)と翼手目(Chiroptera)で少なかった.食性の長期研究事例は時代とともに増加する傾向があった.多くの事例では食性評価に糞分析を用いていたが,特定の分類群に特徴的な分析手法がみられた.80%以上の事例で食性の年次変動がみられたが,多くの事例では食物環境の定量的な評価を行っておらず,さらに個体群パラメータへの影響を評価した事例はごくわずかだった.動物の食性の長期変化の把握は動物の基礎生態の理解に貢献するだけではなく,種子散布や採食に付随する行動などの派生的な研究,ひいては保全戦略の策定などにも貢献すると思われる.

Peripheral artery disease (PAD) usually refers to ischemia of the lower limb vessels. Currently, the estimated number of cases in the world is 202 million. PAD is the third leading cause of atherosclerotic cardiovascular morbidity. The measurement of the ankle-brachial index (ABI) is recommended as a first-line noninvasive test for screening and diagnosis of PAD. An ABI <0.90 is an independent predictor of cardiovascular events and this measurement is useful to identify patients at moderate to high risk of cardiovascular disease. However, there is insufficient evidence to assess the benefits and harms of screening for PAD with the ABI in asymptomatic adults. Lifestyle modifications, including smoking cessation, dietary changes and physical activity, are currently the most cost-effective interventions. Inverse associations with PAD have been reported for some subtypes of dietary fats, fiber, antioxidants (vitamins E and C), folate, vitamins B6, B12 and D, flavonoids, and fruits and vegetables. A possible inverse association between better adherence to the Mediterranean diet and the risk of symptomatic PAD has also been reported in a large randomized clinical trial. Therefore, a Mediterranean-style diet could be effective in the primary and secondary prevention of PAD, although further experimental studies are needed to better clarify this association.

Two types of hydraulic bilateral servomechanisms, symmetrical type and force-feedback type, are proposed and constructed. Characteristics of such bilateral servomechanisms are expressed by a square matrix with four elements which are functions of s. These four elements can be experimentally determined by two series of experiments: one with free slave-end and the other with fixed slave-end. For a symmetrical type the value of the determinant of the characteristic matrix is theoretically equal to the unity and independent of s.

In the first report one of the authors mentioned that a selfinduced vibration of a fluid column can be generated in a pipeline to the end of which a fluttering valve supported by a spring is installed, and that the period of the vibration can be either longer or shorter than the natural period of the pipe according to the charasteristics of the system. In the present paper, vibrations based on the natural one of the water column are studied, and those vibrations can be step-wise waves having periods T=2n/c (n=2, 3, 4…………), which show, as a special case, a rectangular wave having a period T=4/c for n=2. For n=2 the maximum pressure is twice as high as the mean pressure, while for n>3 it increases with n. Further, step-wise waves can be generated even when the mean pressure is higher than the valve-closing pressure, if only the initial disturbance is sufficiently strong.

When a valve, which is installed at the end of a pipe line, has a tendency to decreaseits opening with the increase of the pressure difference, a growing or sustained water-hammer will be generated in the pipe line. In this case, two series of waterhammer are possible : one has a longer period than the fundamental natural period of tae water column, while the other has a shorter period than the latter.

The paper deals with the possibility of generating sustained water-hammer by a fluttering valve which statically increases its opening with the increase of the pressure in the up-stream and which is usually expected to make a system rather stable, contrarily to the valve in the author's previous papers which decreases its opening with the increase of pressure in the up-stream. When the frequency of pressure variation in the up-stream is slightly higher than the natural frequency of the valve, the phase of the motion of the valve treated here is almost reversed relatively to the phase of pressure variation, and the amplitude of the valve is considerably large. This means that the valve can act as a negative resistance for pressure waves having frequencies slightly higher than its natural frequency, if only the damping of the valve motion is sufficiently small.
