本稿は,の企業城下町である宮崎県延岡市を対象に,地方自治体の産業政策の転機を取り上げ,企業城下町の構成主体の対応の多様性に注目して,企業城下町的体質がどのように変容したのかを明らかにした.の影響力の低下は,地域経済だけではなく地方政治にも及び,その両者が相俟って産業政策の変化をもたらしている.1950〜1960年代において,は生産拠点を拡散した一方で,同社延岡地区に対する投資を減少させた.労使協調的な労働組合「全旭連」が延岡市政に対して強い発言力を持っていたため,優遇政策がとられた.1970〜1980年代において,繊維事業を主力とする同社延岡地区は構造不況により縮小・再編が相次ぎ,建設業をはじめとする下請企業は深刻な影響を被った.の影響力低下の中で不況対策を求める商工・建設業者が産業政策の変更を求め,民社党もその動きに加わることで支持を広げた.1990年代以降において,の政治的影響力はさらに低下するが,同社新規事業の成長が産業構造転換を促すものと再評価され,同社を核とした産業発展を目指す政策へと回帰した.

Fluid balance abnormality was observed during plasmapheresis performed using a blood purification device (ACH-Σ; Asahi Kasei Medical Co. Ltd., Tokyo, Japan). Based on this case finding, it was thought that some problems may have occurred in the fluid control system. We verified the operation of the fluid system with obstruction in its circuit. When the circuit for fluid replacement was obstructed, an alarm indicated “abnormalities in filling of fluid replacement”. The alarm could not be reset unless the cause was removed. When the filtration circuit directly behind the plasma separator was obstructed, an alarm indicated “blood leak detection 1”. When the circuit directly before the filter pump was obstructed, an alarm indicated “abnormalities in plasma balance”. For the first and second alerts, it was possible to reset the alarm even if the cause of the alarm was not removed. For the third alert, however, the alarm could not be reset unless the cause of the alarm was removed. When the filtration circuit directly behind the filter pump was obstructed, the status of fluid replacement alone was observed. Thus, excessive body fluid due to excessive fluid replacement may trigger side effects (e.g., elevated blood pressure, cardiac failure, cyanosis, dyspnea, and pulmonary edema).

The physical structure of oriented polyoxymethylene (POM) was studied, and the degree of crystallization and tensile modulus depending on stretching ratio were analyzed. The oriented films were obtained through 2-directional stretching using press elongation method. The stretching ratio reached to 6.0, and the tensile modulus increased from 2.5GPa to 4.5GPa. However, the degree of crystallization slightly decreased from 70% to 65%. The rupture elongation increased in the lower stretching region and reached its peak when the stretching ratio was 1.7%. The characteristics of the physical structure such as the degree of the crystallization and the orientation and dispersion of the lamella were analyzed by measuring the density and the X-ray diffraction. The crystal orientation observed by the X-ray diffraction pattern was isotropic, and the result was confirmed by microscopic photos. The crystallization was found out to be difficult under strong mechanical strength. After thermal aging under various temperatures, the degree of the crystallization increased from 63% to 67%. However, a degree higher than 67% could not be observed. The major factors of such a complicated phenomena seemed to be the higher rate and degree of crystallization of POM than those of PET.

We investigated oligomer-assisted injection molding which is characterized by the injection of oligomer following the injection of synthetic resin into the same die cavity. It was made clear that, when using die cavities designed to give suitable thick-walled parts, oligomer-assisted injection molding can form an oligomer channel similar to the gas channel in the case of gas-assisted injection molding and thus show good transmittance of injection pressure to the resin flow ends.

Proposition concerning desulfurization of mineral oil was published by this journal in 1971, and preliminary observations were made using autoclaves.
Autoclave test: 1970 (Fig. 1)
Double autoclave test: 1973 (Fig. 2)
Very rough scope of solubility equilibrium was derived from data shown in Table 2, and approximate value of partition relation was assumed, Sulfur compound in oil/Sulfur compound in water=100/5 at 300°C for gas oil of 0.98% S, sp.gr. 0.83. Applying this numerical data, to achieve 80% of desulfurization, 16 volume of water is necessary for 1 volume of gas oil in counter flow extraction system and on the contrary 80 volume of water in parallel flow extraction.
Extraction test (Fig. 9) was carried out from 1971 through 1972 and 1973, and experimental data are shown in Table 4 and 5. In Table 5, data of 320°C extraction and 90% desulfurization are informed. An extraction pilot plant was operated from 1972 through 1973. To realize a smooth operation, a long period was needed for adjustment, and some available data (Table 6) were obtained. Unfortunately, a grave disaster broke out October 1973 in the same area where the pilot plant was located. No damage was found in the pilot plant but the experimental operation was forced to be suspended under unfavorable circumstances. At the present moment, the experimental data are too insufficient to conclude the pilot plant test and to design the commercial super-heated-water extraction plant. But, this report is made to inform present status of super-heated-water extraction experiment. Judging from data concerning the repeated treatments (Table 4) and the concentration of extract (Table 6), prospects of improvement by combination of recovering and concentrating processes to the extration column system are very bright. The experiments up to the present are concerning mostly low specific gravity oil, for example gas oil, for the sake of easy extraction operation, but in future the experiments covering oils of higher specific gravity, for example crude oil, should be executed by adjusting specific gravities of the aqueous solution or mixture of oils.
