ジャーナル フリーMy purpose is to explain the discussion of the reform of the American oil import quota system which had been held in the committee of the Cabinet Task Force, and to anticipate for America to select a tariff plan soon or later after a long adjusting period, and to think about the influence upon the world oil market and Japan if America selects a tariff plan.
About this problem, Mr. W. Levy says, if America adopts a tariff scheme, OPEC member countries would strongly insist the reform of their tax-rate, and so the world oil price-level must necessarily go upward. If it is true, Japan, the greatest oil importer, will lose much money.
But I don't think such that under the following reasons.
(1) Even if America adopts atariff plan, the time will be after 1975, and it will be carried out with a long adjusting term. And if that will be so, American tariff scheme won't have so great influence upon the world oil market, considering the affluence of the world oil stock.
(2) The opinion of the OPEC member countries isn't same with each other, some want to revise tax-rate, others want more amount of tax revenue.
(3) After 1985-1990, the share of Atomic power in the first energy supply, will attain a fairly large percentage, and the price of crude oil will be decided in relation to this cost of atomic energy. So the price level of crude oil will go downward to that even point.抄録全体を表示PDF形式でダウンロード (1774K) -

ジャーナル フリーThe LNG industry requires a huge amount of investment in the facilities for liquefaction and marine transportation. In addition, the storage of LNG has posed a serious problem for both shipping and receiving points from technical and economical points Of view.
The storage of LNG was normally made in double-wall metal tanks in the initial stage. However, this method was comparatively higher in cost and required highly advenced techniques in the construction. Furthermore it had another detrimental factor that a suitable location was not always readily available. As a counter-measure to this, an underground storage technique was developed and has since been gradually industrialized on a commercial basis.
Additionally, instead of storing LNG in liquefied form, the underground storage of LNG in regasified form has come into wide use as a large-scale storage method.
Japan is regarded to grow to the world largest importing country of LNG in the near future and, as her consumption of LNG increases she will be faced with the problem of how and where to keep these large supplies stored. A reasonably possible answer to this question will be an underground storage method of LNG in the Pacific belt regions of Japan which will be the principal areas to receive LNG import from abroad.
Also, when the utilization of natural gas becomes prevailing, large scale storing of LNG will be a requisite for the purpose of peak-shaving. The most practical method for this will be underground storage in regasified form and for this purpose those depleted gas (oil) reservoirs located in the northern part of Japan on the Japan Sea will no doubt be most useful.抄録全体を表示PDF形式でダウンロード (1210K) -

ジャーナル フリーLNG (liquefied natural gas) is considerably expensive because it requires additional costs such as liquefaction, transportation, storage and evaporation. While natural gas is less expensive at the location where it is produced. Therefore LNG is mainly used for town gas rather than for feed stock of chemical industry. In Japan, the mass culture of hydrocarbon utilizing micro organism for the production of cattle feed containing large amount of protein is planned recently, using n-paraffine as substrate.
Methane can also be used for the above mentioned purpose and furthermore it is far cheaper than n-paraffine. However research for the culture of methane utilizing micro organism is still in immature stage.
When LNG is evaporated a large amount of cold water can be obtained by latent heat of evaporation.
The aerobic culture of the hydrocarbon utilizing micro organism generates much heat therefore, a large amount of cooling water is required. In case LNG is used, the effect of the said latent heat can be highly evaluated, and cost of cooling can naturally be deducted from the price of LNG抄録全体を表示PDF形式でダウンロード (1516K) -

ジャーナル フリーMany works of surface ignition that is defined as a phenomenon caused by hot metal surfaces or carbon deposits in combustion chamber of a gasoline engine, have been performed by using practical gasoline engine. The data on the surface ignition reported previously indicate that both the number of times and the intensity of the surface ignition vary with the characteristics of an engine, fuels and lubricants in use to the experiments, respectively.
In the present paper, emphasis has been placed on the ignition of combustible gases at a hot surface and flame development in processes of surface ignition in combustion chamber.
It has been shown by the comparative consideration between fundamental researches on ignition of inflammable gases and practical developments on the surface ignition that surface ignition by carbon deposits in an engine can be elucidated from temperature rise of the surface due to an exothermic reaction of the deposits with combustible mixture.抄録全体を表示PDF形式でダウンロード (1581K) -

ジャーナル フリーWith the increase in the number of diesel vehicles, exhaust smoke from diesel engines is becoming a problem one should not ignore. The present position of antismoke legislation is outlined. Theories advanced to explain the combustion processes leading to the formation of smoke, and controlling methods of diesel smoke; the M-Combustion system of MAN, fumigation, fuel additives etc. were described.抄録全体を表示PDF形式でダウンロード (593K) -
