Abstract: Exemplary communication system 1 includes game devices 10, communication terminals 20, and game support server 30. Game devices 10 enable users to perform a multi-play activity. Each of communication terminals 20 runs an application associated with corresponding game device 10. Game support server 30 divides communication terminals 20 into separate communication groups in accordance with a situation of the multi-play activity performed by game devices 10 so that communication terminals 20 belonging to a same communication group can communicate with each other.

Abstract: Catalytic converter (2) includes a catalyst container (10) formed from a tubular blank (10?) and having a catalyst carrier, and a flange member (11) joined to the hollow member. The tubular blank (10?) is subjected to a spinning operation by forming roll or rolls (22A), to form the catalyst container (10) having a desired shape, and the opposed circumferential surfaces of the catalyst container (10) and flange member (11) are forced against each other by the forming roll or rolls (22A) or an array of presser pieces (22B) while the catalyst container and flange member are rotated relatively to each other, so that friction heat is generated for friction-welding the catalyst container and flange member at their joining portions (10b, 11b).

Abstract: A manufacturing method of a catalyst container includes forming a plate member that is partially different in plate thickness or material by joining material plates that are different in plate thickness or material by welding; bending the plate member that is partially different in plate thickness or material to form a hollow material, wherein the hollow material is formed by bending the plate member and joining opposing sides thereof by welding; and changing a sectional shape of the hollow material by a spinning process.

Abstract: While a material pipe and a roller are revolved relative to each other with a predetermined radius, the material pipe and the roller are moved relative to each other in the direction of progress of forming by eccentrically moving the center axis of the material pipe and the revolution axis of the roller relative to each other and simultaneously moving the material pipe and the roller relative to each other in the directions of the axis. During movement in the direction of progress of the forming, an end portion of the material pipe is deflected by controlling the axis-direction moving portion so that the roller is moved relative to the material pipe in the direction of the axis when the circumferential position of the roller, with respect to a circumference of the material pipe, changes from an inner side of the direction of deflection toward an outer side of the direction of deflection.

Abstract: Catalytic converter (2) includes a catalyst container (10) formed from a tubular blank (10′) and having a catalyst carrier, and a flange member (11) joined to the hollow member. The tubular blank (10′) is subjected to a spinning operation by forming roll or rolls (22A), to form the catalyst container (10) having a desired shape, and the opposed circumferential surfaces of the catalyst container (10) and flange member (11) are forced against each other by the forming roll or rolls (22A) or an array of presser pieces (22B) while the catalyst container and flange member are rotated relatively to each other, so that friction heat is generated for friction-welding the catalyst container and flange member at their joining portions (10b, 11b).

Abstract: Individual plate members (W1, W2, W3, W4, W5) that are different in plate thickness or material are joined together by mush seam welding to form hollow material (W, W′), and the rigidity is controlled in individual parts. By spinning the rigidity material (W, W′), a junction (1b) and a cone (1c) are formed in an optimum shape, and a hollow member (1) is manufactured. Thus, the hollow member (1) smooth in juntion and high in welding strength is obtained in spite of thin plate material. When this hollow member (1) is used in a catalyst container, the sealing performance is excellent without being accompanied by an increase in radiant noise or an increase in weight.

Abstract: Apparatus for mounting flexible tires on wheels comprising a vertically movable table lifter, a wheel centering shaft, bead spreading rollers and bead dropping rollers, the table lifter and the bead spreading rollers being provided with annular steps thereon, and means for automatically positioning the table lifter at a height, depending on the size of the wheel carried on the table, at which a predetermined vertical distance is left between the upper edge of the wheel rim and the stepped lower surface of the bead spreading rollers.

Abstract: An air pressure filling system for tires includes a rotary table receiving a plurality of tires arranged in a circle. A rotary distribution joint is placed over the rotary table and is connected to an air source through a pressure control device for controlling an air pressure of the tires at a predetermined pressure. A plurality of air hoses are connected to the rotary distribution joint at one end thereof and are adapted to be connected to the tires by an operator at the other end thereof. The operator simply keeps one place where he is able to connect the hoses to the tires one by one while the tires are transferred on the rotary table, and the tire filled with a predetermined air pressure is returned the operator.
