Abstract: PURPOSE: To provide a rubber composition suitable for an automobile tire or the like capable of forming a vulcanized rubber with excellent processability in an unvulcanized condition and good mechanical properties obtained by compounding a resin obtained by polymerizing a C 5  fraction of a cracked oil to a diene rubber.  
     CONSTITUTION: A C 5  fraction which is a fraction of a cracked oil formed by cracking naphtha, kenosene or the like and contains unsaturated hydrocarbons mainly comprising 5C hydrocarbon components is polymerized in an untreated condition in the presence of a cationic polymerization catalyst (e.g. AlCl 3 /alcohol/toluene solution-type composite catalyst) to obtain a resin not substantially containing gel with bromine value of 70W240 and softening point of 200°C or lower. This resin 4W40pts.wt. is compounded with 100pts.wt. of a diene rubber, e.g., natural rubber, along with other compounding agents, e.g., carbon black, according to nedessity to obtain a composition.  
     EFFECT: A vulcanized article with remarkably high tensile strength, hardness and cut resistance as well as balanced physical properties can be obtained.

Title: Self-supported pressure vessel
Inventor: SHIMIZU NORIHIRO
IPC: B65D1/02
Filed: 1990-03-14
Abstract: PURPOSE:To improve characters of self-standing and running stability of a container made of synthetic resin, by a method wherein at least a part of the periphery of the container is expanded larger than a most expanded part of the container by a prescribed size between a body center of the container which forms a circular cross section in substantially horizontal direction with respect to the container standing direction and a leg part, excluding a recessed part extending toward a center of a closing bottom and a grounding flat part. CONSTITUTION:A self-supported pressure vessel has a mouth and neck part 11 the upper end of which is formed in an open mouth flange part, a shoulder part 12 which is adjacent to the part 11, a body part 1 which is adjacent to the shoulder part 12, an expanded part 3 which is adjacent to the body part 1 for absorbing shock, and a bottom part 2 which closes a released part lower than the expanded part 3 in the center. The part 3 is shaped to expand in the dimensional direction for absorbing shock. When the containers contact with each other on a line conveyor, they contact at the expanded part 3. In this instance, as the expanded part 3 is arranged on a grounding flat part 6 side with respect to the center of the container, the center of gravity is positioned rather low, and therefore a character of running stability is good. The expanding degree is 1 to 30% compared to a most expanded part of the container. If it is less than 1%, a character of self-standing cannot be satisfied, and a character of running stability on the line conveyor is not enough, either. If over 30%, deviation of thickness is likely to occur at the expanded part 3, which results in reduction of pressure resistance of the whole of the container.

Title: Thrust bearing
Inventor: KUBO YOSHIHIRO
IPC: F16C17/22
Filed: 1978-05-23
Abstract: PURPOSE: To countervail thermal displacements of a casing and a rotor, by locating a thrust bearing metal itself at a bearing stand so that it can move relatively in an axial direction.  
     CONSTITUTION: A cylindrical inner surface 3 being concentric with a shaft 2 of a rotary machine is placed at the inside of a bearing stand 1. Sliding surfaces 5A and 5B of a bearing metal 4, which is supported so that it can move in an axial direction on the cylindrical surface 3, is in a contact with the side surfaces of thrust collars 6A and 6B formed in one body with the shaft 2. The thrust bearing metal 4 is supported at the bearing stand 1 so that the metal 4 can move in the direction of the shaft 2 and the metal 4 is coupled with the end of a casing on the thrust bearing side by means of a coupling member 10. Thus when the casing 8 moves to the left due to a thermal expansion, the thrust bearming metal 4 also move. At that time, the thrust collars 6A and 6B move to the left due to a thermal expansion of the rotor and thus the thermal displacements of the casing 8 and the rotor can be countervailed.
