Abstract: In a method and apparatus for continuous shaping of carbon-fiber-reinforced plastic tubes, a carbon fiber prepreg in tape form impregnated with a first thermosetting resin is laminated on and around a mandrel; the laminate provided on said mandrel is preheated; and the preheated laminate is pulled in and through a hot die together with the mandrel, during which it is gelled, cured, and shaped into a carbon-fiber-reinforced plastic tube, wherein a second thermosetting resin is uniformly supplied onto the outer circumference of the laminate in a resin squeezing zone in the hot die.

Abstract: A thin-film forming device has a support frame for supporting a substrate to be coated with a thin film, a reaction chamber having a space surrounded by the substrate supported on the support frame, side walls mounted under both sides of the substrate and a bottom wall mounted under the side walls, an atomizer for delivering an atomized solution of a material to be coated on the surface of the substrate, a heater disposed behind the substrate for heating the substrate to a temperature higher than a reaction temperature of the material, and a nozzle connected to the atomizer and disposed in the reaction chamber in facing relation to the substrate for spraying the atomized solution toward the surface of the substrate, and cooling means for cooling at least an inside portion of the bottom wall in facing relation to the substrate to a temperature below the reaction temperature of the material.

Abstract: A process for preparing lower olefin using a calcium phosphate modified zeolite type catalyst is disclosed which is capable of reducing the decomposition of methanol into CO and CO.sub.2 and increasing the olefin selectivity. In the process, the reaction of methanol and/or dimethyl ether is carried out in the presence of an aluminosilicate zeolite-type catalyst which has a Ca-containing compound and a P-containing compound contained therein in predetermined amounts.
