ジャーナル フリーThe production and demand for petroleum waxes yearly increased during these ten years, and they are used much in many fields, such as in reinforcing paper materials, manufacturing chlocinated paraffin, candles, matches, and stationeries, and in bending with raw rubber and so on. Petroleum waxes thus now become the necesaries of our modern lives.
Owing to many kinds of new agents to be blended with waxes for improving their properties, petroleum waxes are converted into new “plastics”, and the old image of waxes is now altered.
Their new characteristics enable to open more demands hereafter, especially in paper-reinforcement.
Petroleum waxes will also be used for raw materials petrochemical and fermentation industries in whcih mass productions of fatty acids, alcohols, α-olefins or proteins from waxes are under planning, and the petroleum wax industry faces to its bright future.抄録全体を表示PDF形式でダウンロード (633K) -

ジャーナル フリーDescription is made on delayed coking process and fluid coking process for mass production of petroleum coke.
Qualities and properties of petroleum coke (i. e. graphitizability, density, strength etc.) are strongly influenced by operating conditions (carbonization temperature, pressure, rate of heating) and constitutions of starting oils.
The mechanisms of coke formation are also discussed.抄録全体を表示PDF形式でダウンロード (1451K) -

ジャーナル フリーThe Wankel engine has been developed with quick tempo since its experimental engine first appeared ten years ago. Now Toyo Kogyo is making production of the 4000 rotary piston engine passenger cars per month and also in West Germany, some makers put the rotary engines for various applications on the market.
This paper summarizes the principle, the features, the present and the future of the Wankel engine which, we are sure, has the suitable characteristics for various applications.抄録全体を表示PDF形式でダウンロード (1513K) -

ジャーナル フリー1. Setonaikai (the Inland Sea of Seto) Area, in this article, includes 11 prefectures, Wakayama, Osaka, Hyogo, Okayama, Hiroshima, Yamaguchi, Fukuoka, Oita, Ehime, Kagawa and Tokushima.
The position of this area in our country is as follows,
land space 15.9%
population 26.1%
manufacturing output 21.2%
per head income* about 250 thou. yen/year
(* national average 207 thou. yen/year)
2. Features of the industrial development of the area are to be summarized.
(1) The history of the industrial development is recent one.
(2) The development has been largely depended on the heavy industries.
From 1962 to 1968 annually about 30% of the new location of manufacturing factories in Japan has been in the area. But, for example, as to the chemical industry, the proporation was 37% in the same period, and as to the oil and coal products industry the proporation was 58%.
Now, 41% of the total output of Chemicals, 38% of oil and coal products and 52% of iron and steels in Japan are produced in the area.
(3) These industries need large scale marine traffic facility and the area fit these conditions very well.
(4) Industrial development has not been concentrated but scattered to many regions. We count fifteen seaside industrial areas and they are separated geographically and economically.
(5) The area is relatively lack of the accumulation of inland type industries such as machinery and electric instruments.
3. “The Perspective of the Regional Development of Industries” (MITI, Dec., 1968) forcasts that the manufacturing output of this area will be 24 trillions yen in 1975 and 47 trillions yen in 1985 (It was 9.7 trillions yen in 1965). The plans of constructing bridges across the inland sea, new express rail road, highway network and super scale industrial basement along the Sea of Suha will support the industrial growth.
4. But, we have to solve many problems, -how to secure a great quantity of land and water for use of industries, how to treat crowded marine traffics, how to protect the sea from water pollution and how to develop inland industries.抄録全体を表示PDF形式でダウンロード (1145K) -

ジャーナル フリーSix kinds of Japanese coals-Taiheiyo (77.8%C), Bibai (81.1%C), Akabira (83.4%C), Yubari (86.2%C), Hashima (87.2%C) and Nishikawachi (89. 8%C) were heat treated at the temperatures from 600 to 900°C and the yields of products, proximate and ultimate analyses including helium densities of the heat treated coals were investigated.抄録全体を表示PDF形式でダウンロード (1074K) -

ジャーナル フリーConsiderable quantities of fuel oil additives are being consumed in Japan for diesel engines and boilers. However, no detailed figures on supply and demand of these additives have been published yet.
This interim report, based on 19 answers out of 50 questionnaires mailed to additive manufacturers and marketers, gives a brief outline of the survey sponsored by the Fuel Society.
According to the survey, annual consumption of fuel oil additives by these 19 firms totalled 20, 000 kiloliters: broken down into land (70percent) and marine (30 per cent) uses. The survey also disclosed that approximately 85 per cent of fuel oils being consumed by main engines for marine purposes use the additives, while approximately 45 per cent of fuel oils for auxiliary engines use the additives.
As regards the consumption for land purposes, primarily for pulp, chemical, textile, electrical machinery, and food industry uses, the additives are used by approximately 53percent of all fuel oils consumed.抄録全体を表示PDF形式でダウンロード (653K) -
