Title: Extrusion molding machine mixing screw
Inventor: NAKAMURA KAZUYUKI
IPC: B29C48/395
Filed: 1978-05-02
Abstract: PURPOSE:To increase the amount of extrusion in extrusion molding machines by providing a mixing unit between a compressing unit and a measuring unit. CONSTITUTION:Solid resin transported to mixing unit D is divided into six parts by six projections provided in six groove-shaped passage 113, and these divided  parts are made to flow in six groove-shaped passage 12, which are arranged at equal intervals in the direction perpendicular to, and at an angle of inclination of 45 deg. with respect to, the axis of screw 10. Consequently, a large solid resin is retained on the side of supply part A of projection 13, and while it is retained, it is heated and melted by the cutting action proportional to the depth of groove-shaped passage 113 due to the rotation of screw 10. When the solid resin becomes small in this way, it passes groove-shaped passage 12, and further, its melting is accelerated by the side wall of projection 13 as it moves forward. Consequently, it is possible to increase the amount of extrusion.

Filed: 1993-03-12
Abstract: PURPOSE:To obtain a fat emulsion for intravenous injection being fast in metabolism, having fat particles with small particle diameter and excellent in stability by including glyceride used as a fat ingredient as an active ingredient. CONSTITUTION:The fat emulsion for intravenous injection contains diglyceride [especial1y preferably a compound of the formula (two groups among R<1> to R<3> are acyl derived from 6-22C saturated or unsaturated fatty acid and the remainder is H) as an active ingredient. This emulsion is a fat emulsion for intravenous injection administered to patients as an energy source or essential fatty acid source. Namely, this emulsion is a stable emulsion rapidly metabolized after administration, hardly having possibility causing embolization in the endothelial system of lung, liver and spleen and having small particle diameter. Since diglyceride is used as the fat component, uniform and stable fat particles having small particle diameter can be obtained and since these fat particles are diffused into structure of whole body without being englobed by liver Kupffer cell and are rapid in loosing rate in blood, gas exchange between oxygen and CO2 by erythrocyte is not interfered. As a result, the emulsion has especially high safety.

Abstract: PROBLEM TO BE SOLVED: To mold a low double refraction optical element without generating a weld or a warp fault on a mirror surface by incorporating a holding dowel for surrounding an exterior of a core for forming a mold body, and a heat insulation layer between a metal thin film layer of a surface of the core and the surface of the core, and providing a high frequency induction heating coil on a periphery of the core through the layer. SOLUTION: A zirconia layer formed by a sputtering method or the like is used as a heat insulation layer 6. A general purpose mold steel material is used as a material of fixed and movable side cores 3, 4. Nonmagnetic material or copper alloy is used as fixed and movable side holding dowels 1, 2. High frequency induction heating coils 11 of insulator-coated wires are wound on outer peripheries of the cores 3, 4. A resin is injected in a cavity 5 at a lower pressure of the degree for generating a shrink, and hence no weld is generated due to heating at a glass transition point or above on a surface of the mirror surface (metal thin film 7) of the cores 3, 4. Since a surface of a cavity except the mirror surface is not heated, a resin near the surface is immediately solidified and shrunk.  Thus, no shrink or weld occurs on the mirror surface, and an optical element having a low double refraction is obtained by a low pressure molding.
