Abstract: The present invention provides a thin multilayer magnetic recording medium having improved electromagnetic conversion property and durability, comprising coating layers of a lower non-magnetic layer and an upper magnetic layer. The non-magnetic layer of this magnetic recording medium comprises a non-magnetic needle body having an average major axis length of 0.25 to 1.0 .mu.m and an average minor axis length of 0.005 to 0.0151 .mu.m, a first binding resin having a glass transition temperature (Tg.sub.1) of 30 to 50.degree. C., and fatty acid ester. The content of the first binding resin is 15 to 30 wt % with respect to the non-magnetic needle body. The content of the fatty acid ester is 2 to 15 wt % with respect to the first binding resin. The magnetic layer having a dry thickness of 0.5 .mu.m or less comprises ferromagnetic powder and a second binding resin having a glass transition temperature (Tg.sub.2) of 40 to 70.degree. C. Tg.sub.1 is at least 5.degree. C. lower than Tg.sub.

Abstract: 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.

Abstract: 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.

Abstract: A predetermined amount of liquid is to be filled into a container. The weight of liquid contained within a metering container is measured by a balance and a filling control valve provided at an outlet of the metering container is controlled in response to a signal issued from the weighing balance. Thereby a predetermined amount of the liquid can be filled from the metering container into the container. A control unit opens and closes the filling control valve and a feed control valve connected to a liquid feed source in response to a signal issued from the weighing balance. An inlet of the metering container is connected via a flexible pipe to an outlet of the feed control valve, and an outlet of the metering container is connected via a flexible pipe to an inlet of the filling control valve.
