    摘要： An animation solid is created by an animation solid generator such that the shape of its cross section at t=t0 coincides with the shape of the contour of an object contained in a frame to be displayed at t=t0, wherein time t is set in the height z direction of the solid. For creation of this solid, topological considerations, including connected components and the tree structure of contours, are used. By chopping this solid, intermediate dividing can be performed. The basis of the topological geometry rests on Morse theory.

    摘要： A method for treating waste water containing nitrate ion which comprises supplying raw waste water from a tube (2), formalin from a tube (3) and an aqueous alkaline solution from a tube (4) to a mixing vessel (1), while agitating with an agitator (5), so the resultant mixture has a pH of 7 or higher, transferring the mixture from an outlet pipe (6) to a catalyst bed (9) through a tube (8) by a pump (7), and discharging the treated fluid drained from the catalyst bed (9) to the outside of the system through pipe (11), wherein the catalyst bed (9) is provided within a jacket (10), through which a liquid such as water flows, for the temperature control, and is packed with a support type catalyst comprising spherical type activated carbon and Pd—Cu supported thereon. The type of reactor containing the support type catalyst in the catalyst bed (9) may be a fluidized bed or a fixed bed. The above method can be suitably used for reducing nitrate ion to nitrogen by the use of formalin as a reducing agent at a low treating cost and with a low selectivity of ammonia as a by-product.

    摘要： In an image generating system or apparatus, a first storage unit stores key frames and corresponding point data therefor. A performance specifying unit determines a processing performance of a user terminal. A resolution decision unit determines a resolution of motion pictures (intermediate frames) to be generated or reproduced in accordance with the determined processing performance. An intermediate frame generator generates intermediate frames at the determined resolution by interpolating the key frames based on the corresponding point data.

    摘要： A liquid hydrocarbon such as a natural gas liquid generally contains a small amount of mercury in a state of elemental mercury, ionized mercury, ionizable mercury compounds, which are requested to be removed thoroughly. Further, organic mercury compounds are contained in some natural gas liquid and other liquid hydrocarbons depending on their district of production, and its removal is also necessary.Already known adsorbents can adsorb elemental mercury and organic mercury compounds in a liquid hydrocarbon, but they hardly adsorb ionizable mercury compounds and ionized mercury derived from the ionizable mercury compounds.According to the preesent invention which comprises contacting the liquid hydrocarbon with a sulfur compound represented by a general formula MM'S.sub.x, wherein M is selected from a group consisting of alkali metal and ammonium radical, M' is selected from a group consisting of alkali metal, ammonium radical and hydrogen an x is a number of at least 1, the sulfur compound and mercury in the liquid hydrocarbon reacts to form mercury sulfide which is insoluble in the liquid hydrocarbon to be separated therefrom.If the liquid hydrocarbon contains organic mercury compounds together with elemental mercury ionized mercury and ionizable mercury compounds, the above-mentioned process is to be combined with a process of contacting the liquid hydrocarbon with an adsorbent comprising heavy metal sulfide to adsorb the organic mercury compounds together with the mercury sulfide which is formed in the above-mentioned process.

    摘要： Disclosed is a method for production of lower olefins from a raw material containing dimethyl ether (DME), which can produce lower olefins (e.g. propylene) with good yield and in an economically advantageous manner by prolonging the time until the reversible deactivation of a zeolite catalyst and preventing the irreversible deactivation of the catalyst, can reduce the amount of water to be recycled to increase the thermal efficiency of the process, and can simplify the facilities and operations. Also disclosed is a method for improving the yield of propylene with good efficiency under practical operating conditions. A feed gas which comprises a DME-containing feedstock gas and an additive gas and further contains steam at a specific proportion is introduced into an olefin synthesis reactor to contact the feed gas with a zeolite catalyst, thereby producing a hydrocarbon product containing C2-C5 olefins. Propylene or the like is separated/collected from the hydrocarbon product, and at least a part of the remainder is used as at least a part of the additive gas.
