Abstract: A balloon is formed from a water-soluble film which mainly comprises a polyvinyl alcohol. Coloring agents as food additives are used for pigmenting the balloon. The balloon per se is soluble in water upon coming in contact with water and accordingly, it never becomes a cause of environmental pollution. The coloring agents used are those for use in foods and thus they do not become a cause of environmental pollution.

Abstract: A joint structure for removably attaching a ball member to an end of a bar member to form a truss structure is disclosed having an engagement member attached to the ball member, which engagement member has an exterior portion extending outwardly of the outer surface of the ball member, and an attachment device associated with the end of the bar member which removably engages the exterior portion of the engagement member. The joint structure according to the present invention may be utilized with bar members with or without tension rods extending through the bar member. The ball structure may be a spherical shell made of metal or fiber reinforced plastic which is located within a hollow concrete sphere. The spherical shell is not removed from the interior of the concrete sphere, but, instead, is used to increase the tensile force resistance of the ball member. The spherical shell may be imbedded in the ball member at the time of forming the concrete ball and can be used as a molding core.

Abstract: Impurities containing a pungent taste component are removed from a hot red pepper oleoresin as a starting material therefrom by a supercritical gas extraction method using a carbon dioxide as an extracting reagent, and the extraction residue is used as a red coloring matter. Even when the hot red pepper is used as the raw material, the invention can provide a natural red coloring matter evaluated as having "no pungent taste" by an organoleptic test. When the natural red coloring matter is prepared from the hot red pepper as the raw material by the supercritical gas extraction method, the invention can drastically reduce the gas pressure of the extracting reagent in comparison with the prior art.

Abstract: This invention relates to a reinforcement member to be mounted internally in the doors of an automobile, and more particularly to the member comprising two parallel flat members and one or two corrugated members which connect said two parallel members in such a manner as to position the ridges of folds thereof perpendicular to the surfaces of the plate members. The reinforcement member is mounted internally in car doors. When the car receives an impact from the side of the door, the corrugated surfaces of the member can distribute the impact evenly by deforming themselves into a fan-like shape to thereby prevent the door from being abruptly folded at one point.

Abstract: A method for forming projections on the periphery of a pipe in order to provide branch pipes, such as a manifold for automobiles, is characterized in that the branch pipes are formed by a bulging process to have a predetermined thickness without thinning. A first embodiment includes the step of indenting a pipe member by press work or the like, at locations close to the position of a projection which is to be formed, in a preliminary deforming process. The deformed pipe member is then placed in a bulge mold having a recess or space, with the pipe member being positioned so that the indentations in the pipe member lie adjacent the recess in the bulge mold. Pressurized fluid is then introduced into the interior of the pipe member to bulge the wall of the pipe member into the recess in the bulge mold. A second embodiment employs a bulge mold having fixed recesses or spaces and variable recesses or spaces for forming a plurality of projections.

Abstract: A plunger pump comprises a cylinder (1); a plunger (2) reciprocating within said cylinder; a sucking chamber (1a) formed upon a top of said plunger; a sucking pipe (4) and a discharge pipe (5) communicated with said sucking chamber; and slidable means (1b) formed upon an inner wall of said cylinder in the proximity of an open end thereof. The sucking chamber and the slidable means are intercepted from each other by an intercepting fluid stream formed therebetween, thereby any contaminants occurring from the slidable means are prevented from being penetrated into the sucking chamber, and discharged outside the plunger pump together with the intercepting fluid stream.

Abstract: A structure and a method of manufacture of a manifold which is to be mounted either on the intake side or on the exhaust side of an internal combustion engine, which is formed by projecting branch pipes from one side of a pipe member in the form of straight pipes. The manifold is further provided with grooves for gas leakage prevention and for rotation prevention at the connection between branch pipes and flanges caulked to the free ends thereof.

Abstract: The present invention relates to a preservation method and preservation apparatus which are suitable for preserving perishable goods for a long period of time.

Abstract: A manifold which is mounted either on the intake side or on the exhaust side of an internal combustion engine. A main body of a manifold is divided into an end manifold, at least one intermediate manifold and a base manifold. Branch pipes are formed by a bulging process to project upright branch pipes on a side of each manifold, and manifolds are connected on ends with gaskets interposed therebetween so that the bending moment caused by the expansion of metal members due to hot exhaust gases may be absorbed instead of being concentrated on the roots of the manifold to enhance the durability of the manifold.

Abstract: A method and an apparatus for manufacturing cam shafts in which cam members are held in respective rotatable axially aligned rings by holding members connected within the rotatable rings so that a pipe member cam be inserted through respective aligned holes of the cam members. The rings are individually rotatable so as to rotate the cam members by respetive predetermined angles. After a pipe member is inserted in the holes of the individually rotated cam members, a bulging process device seals respective opposite ends of the pipe member and forces a pressurized fluid into the pipe so as to bulge the pipe to fix the pipe in the respective holes, thereby to form the cam shaft.
